5 Best Bitcoin Mining Hardware ASIC Machines (2020 Rigs)

I literally have tens of thousands of dollars in top-shelf hardware, looking to repurpose some before selling on eBay to build a NAS system, possibly a dedicated firewall device as well. o_O

Q1) What will you be doing with this PC? Be as specific as possible, and include specific games or programs you will be using.**

A1) This will be a dedicated NAS system for my home network. As such, I'm looking to have it:

- Host ##TB's of 720, 1080 & up resolution Movies and TV Shows I'm about to begin ripping from a MASSIVE DVD & Blueray collection I have.

- My kids are big on Minecraft. I understand it's possible to host your own "worlds" (or whatever they call the maps you can build) on your own "server". I think it would be pretty neat to offer them (& their friends - if can be done 'safely/securely') their own partition on one of my NAS HDD's.

- I also have accounts with a couple diff VPN companies... I understand it's possible (?) to sync said VPN's with a NAS, this might be a more relative topic on the next point/purpose...

- I'd like to be able to remotely link to this NAS for when I travel overseas and want to stream at my temp location from my house/this NAS.
______________________
Q2) What is your maximum budget before rebates/shipping/taxes?**

* A2) Here's where I make matters more complicated than most others would... I've been an advocate for Bitcoin and crypto-currencies in general since 2013. I invested in a small mining outfit back in 2014 (strictly Bitcoin/ASIC's). One of my buddies is the President of a large-scale mining operation (foreign and domestic) and he convinced me to dabble in the GPU mining-space. I made my first hardware purchase in Q4, 2017 and launched a small-scale GPU-Farm in my house since then. I had the rigs mining up until Q3 of 2018 (not cost-efficient to keep on, especially living in SoFlo) and since then, the hardware's been collecting dust (& pissing off my family members since they lost access to 3X rooms in the house - I won't let anyone go near my gear). One of my New Years Resolutions for 2019 was to clear out the house of all my mining equipment so that's all about to go up on eBay. So "budget" is relative to whatever I "MUST" spend if I can't repurpose any of the parts I already have on hand for this build... (Anyone having something I "need" and is looking to barter for one of the items I'll list later on in here, LMK).
______________________
Q3) When do you plan on building/buying the PC? Note: beyond a week or two from today means any build you receive will be out of date when you want to buy.**

A3) IMMEDIATELY! :)
______________________
Q4) What, exactly, do you need included in the budget? (ToweOS/monitokeyboard/mouse/etc\)**

A4) Well I had a half-assed idea approximately 1 year ago that it might be wise to build a bunch of 'gaming rigs' to sell on eBay with my intended repurposed mining hardware so I went on a shopping spree for like 6 months. That said; I've got a plethora of various other components that aren't even unboxed yet. 90% of the items I've purchased for this additional project were items that were marked down via MIR (mail-in-rebates) & what-not...
AFAIK, there are only 3X items I absolutely do not have which I 'MUST' find. Those would be - 1) Motherboard which accepts "ECC RAM". 2) CPU for said MOBO. 3) Said "ECC RAM".\* 
______________________
Q5) Which country (and state/province) will you be purchasing the parts in? If you're in US, do you have access to a Microcenter location?**

A5) I'm located in Southwest Florida. No Microcenter's here. Best Buy is pretty much my only option although I am a member of Newegg, Amazon & Costco if that makes any difference?
______________________
Q6) If reusing any parts (including monitor(s)/keyboard/mouse/etc), what parts will you be reusing? Brands and models are appreciated.**

A6) In an attempt to better clean up this Q&A, I'm going to list the items I have on-hand at the end of this questionnaire in-case passers-by feel like this might be a TLDR.* (Scroll to the bottom & you'll see what I mean).
______________________
Q7) Will you be overclocking? If yes, are you interested in overclocking right away, or down the line? CPU and/or GPU?**

A7) I don't think that's necessary for my intended purpose although - I'm not against it if that helps & FWIW, I'm pretty skilled @ this task already (it's not rocket science).
______________________
Q8) Are there any specific features or items you want/need in the build? (ex: SSD, large amount of storage or a RAID setup, CUDA or OpenCL support, etc)**

A8) As stated in A4; ECC RAM is non-negotiable... RAID seems like a logical application here as well.

- This will predominantly be receiving commands from MacOS computers. I don't think that matters really but figured it couldn't hurt to let you guys know.\*

- I'd also be quite fond of implementing "PFSENSE" (or something of that caliber) applied to this system so I could give my Netgear Nighthawks less stress in that arena, plus my limited understanding of PFSENSE is that it's ability to act as a firewall runs circles around anything that comes with consumer-grade Wi-Fi routers (like my Nighthawks). Just the same, I'm open to building a second rig just for the firewall.\*

- Another desirable feature would be that it draws as little electricity from the wall as possible. (I'm EXTREMELY skilled in this arena. I have "Kill-A-Watts" to test/gauge on, as well as an intimate understanding of the differences between Silver, Gold, Platinum and Titanium rated PSU's. As well as having already measured each of the PSU's I have on-hand and taken note of the 'target TDP draw' ("Peak Power Efficiency Draw") each one offers when primed with X amount of GPU's when I used them for their original purpose.\*

- Last, but not least, sound (as in noise created from the rig). I'd like to prop this device up on my entertainment center in the living room. I've (almost) all of the top-shelf consumer grade products one could dream of regarding fans and other thermal-related artifacts.

- Almost forgot; this will be hosting to devices on the KODI platform (unless you guys have better alternative suggestions?)
______________________
Q9) Do you have any specific case preferences (Size like ITX/microATX/mid-towefull-tower, styles, colors, window or not, LED lighting, etc), or a particular color theme preference for the components?**

A9) Definitely! Desired theme would be WHITE. If that doesn't work for whatever reason, black or gray would suffice. Regarding "Case Size". Nah, that's not too important although I don't foresee a mini-ITX build making sense if I'm going to be cramming double digit amounts of TB in the system, Internal HDD's sounds better than a bunch of externals plugged in all the USB ports.
______________________
Q10) Do you need a copy of Windows included in the budget? If you do need one included, do you have a preference?**

A10) I don't know. If I do need a copy of Windows, I don't have one so that's something I'll have to consider I guess. I doubt that's a necessity though.

______________________
______________________
______________________
Needless to say, I have at least 1X of everything mentioned above. In most all cases, I have multiples of these items but obviously won't be needing 2X CPU's, Cases, etc...

Naturally, I have GPU's. Specifically;

At least 1X of every. Single. NVIDIA GTX 1070 TI (Yes, I have every variation of the 1070 ti made by MSI, EVGA and Zotac. The only brand I don't have is the Gigabyte line. My partners have terrible experience with those so I didn't even bother. I'm clearly not going to be needing a GPU for this build but again, I'm cool with discussing the idea of a barter if anyone reading this is in the market for one.

I also have some GTX 1080 TI's but those are already spoken for, sorry.

It's my understanding that select CPU's I have on this list are ECC Friendly and AFAIK, only 1 of my MOBO's claims to be ECC Friendly (The ASROCK AB350M PRO4), but for the life of me, I can't find any corresponding forums that confirm this and/or direct me to a listing where I can buy compatible RAM. Just the same, if I go w/ the ASROCK MOBO, that means I'd be using one of the Ryzens. Those are DEF. power hungry little buggers. Not a deal-breaker, just hoping to find something a little more conservative in terms of TDP.


In closing, I don't really need someone to hold my hand with the build part as much as figuring out which motherboard, CPU and RAM to get. Then I'm DEFINITELY going to need some guidance on what OS is best for my desired purpose. If building 2X Rigs makes sense, I'm totally open to that as well...
Rig 1 = EPIC NAS SYSTEM
Rig 2 = EPIC PFSENSE (or the like) DEDICATED FIREWALL

Oh, I almost forgot... The current routers I'm using are...
1X Netgear Nighthawk 6900P (Modem + Router)
1X Netgear Nighthawk X6S (AC 4000 I believe - Router dedicated towards my personal devices - no IoT &/or Guests allowed on this one)
1X TP-Link Archer C5 (Router). Total overkill after implementing the Nighthawks but this old beast somehow has the best range, plus it has 2X USB ports so for now, it's dedicated towards my IoT devices.
---- I also have a few other Wi-Fi routers (Apple Airport Extreme & some inferior Netgear's but I can only allocate so many WiFi Routers to so many WiFi channels w/out pissing off my neighbors) On that note, I have managed to convince my neighbors to let me in their house/WiFi configuration so we all have our hardware locked on specific, non-competing frequencies/channels so everyone's happy. :)


Please spare me the insults as I insulted myself throughout this entire venture. Part of why I did this was because when I was a kid, I used to fantasize about building a 'DREAM PC' but could never afford such. To compensate for this deficiency, I would actually print out the latest and greatest hardware components on a word document, print the lists up & tape to wall (for motivation). I was C++ certified at the age of 14 and built my first PC when I was 7. At the age of 15 I abandoned all hope in the sector and moved on to other aspirations. This entire ordeal was largely based off me finally fulfilling a childhood fantasy. On that note = mission accomplished. Now if I'm actually able to fulfill my desires on this post, I'm definitely going to feel less shitty about blowing so much money on all this stuff over the last couple years.

TIA for assisting in any way possible. Gotta love the internets!


THE END.
:)

EDIT/UPDATE (5 hours after OP) - My inbox is being inundated with various people asking for prices and other reasonable questions about my hardware being up for sale. Not to be redundant but rather to expound on my previous remarks about 'being interested in a bartetrade' with any of you here...

I did say I was going to sell my gear on eBay in the near future, I also said I wanted to trade/barter for anything relative to helping me accomplish my OP's mission(s). I'm not desperate for the $$$ but I'm also not one of those people that likes to rip other people off. That said; I value my time and money invested in this hardware and I'm only willing to unload it all once I've established I have ZERO need for any of it here in my home first. Hence my writing this lengthy thread in an attempt to repurpose at least a grand or two I've already spent.

One of the most commonly asked questions I anticipate receiving from interested bodies is going to be "How hard were you on your hardware?" Contrary to what anyone else would have probably done in my scenario which is say they were light on it whether they were or weren't, I documented my handling of the hardware, and have no problem sharing such documentation with verified, interested buyers (WHEN THE TIME COMES) to offer you guys peace of mind.

I have photo's and video's of the venture from A-Z. I am also obliged to provide (redacted) electricity bill statements where you can correlate my photo's (power draw on each rig), and also accurately deduct the excess power my house consumed with our other household appliances. Even taking into consideration how much (more) I spent in electricity from keeping my house at a constant, cool 70-72F year-round (via my Nest thermostat). Even without the rigs, I keep my AC @ 70 when I'm home and for the last 1.5-2 years, I just so happened to spend 85% of my time here at my house. When I would travel, I'd keep it at 72 for my wife & kids.
Additionally; I had each GPU 'custom' oveunderclocke'd (MSI Afterburner for all GPU's but the EVGA's).*
I doubt everyone reading this is aware so this is for those that don't.... EVGA had the brilliant idea of implementing what they call "ICX technology" in their latest NVIDIA GTX GPU's. The short(est) explanation of this "feature" goes as follows:

EVGA GPU's w/ "ICX 9 & above" have EXTRA HEAT/THERMAL SENSORS. Unlike every other GTX 1070 ti on the market, the one's with this feature actually have each of 2/2 on-board fans connected to individual thermal sensors. Which means - if you were to use the MSI Afterburner program on one of these EVGA's and create a custom fan curve for it, you'd only be able to get 1/2 of the fans to function the way intended. The other fan simply would not engage as the MSI Afterburner software wasn't designed/coded to recognize/ communicate with an added sensor (let alone sensor'S). This, in-turn, would likely result in whoever's using it the unintended way having a GPU defect on them within the first few months I'd imagine... Perhaps if they had the TDP power settings dumbed down as much as I did (60-63%), they might get a year or two out of it since it wouldn't run as near as hot, but I doubt any longer than that since cutting off 50% of the cooling system on one of these can't be ignored too long, surely capacitors would start to blow and who knows what else...
(Warning = RANT) Another interesting side-note about the EVGA's and their "Precision-X" OveUnderclocking software is that it's designed to only recognize 4X GPU's on a single system. For miners, that's just not cool. My favorite builds had 8X and for the motherboards that weren't capable of maintaining stable sessions on 8, I set up with 6X. Only my EVGA Rigs had 3 or 4X GPU's dedicated to a single motherboard. Furthermore, and as stated in an earlier paragraph, (& this is just my opinion) = EVGA SOFTWARE SUCKS! Precision X wasn't friendly with every motherboard/CPU I threw at it and their extension software for the CLC Close-Loop-Cooling/ CPU water-coolers simply didn't work on anything, even integrating into their own Precision-X software. The amount of time it took me to finally find compatible matches with that stuff was beyond maddening. (END RANT).
Which leads me to my other comments on the matter. That's what I had every single 1070 ti set at for TDP = 60-63%. Dropping the power load that much allowed me to bring down (on average) each 1070 ti to a constant 110-115W (mind you, this is only possible w/ "Titanium" rated PSU's, Platinum comes pretty damn close to the Titanium though) while mining Ethereum and was still able to maintain a bottom of 30 MH/s and a ceiling of 32 MH/s. Increasing the TDP to 80, 90, 100% or more only increased my hashrates (yields) negligibly, like 35-36 MH/s TOPS, which also meant each one was not only pulling 160-180W+ (Vs. the aforementioned 115'ish range), it also meant my rigs were creating a significantly greater amount of heat! Fortunately for the GPU's and my own personal habits, I live in South Florida where it's hot as balls typically, last winter was nothing like this one. Increasing my yields by 10-15% didn't justify increasing the heat production in my house by >30%, nor the added electricity costs from subjecting my AC handlers to that much of an extra work-load. For anyone reading this that doesn't know/understand what I'm talking about - after spending no less than 2-3 hours with each. and. every. one. I didn't play with the settings on just one and universally apply the settings to the rest. I found the 'prime' settings and documented them with a label-maker and notepad. Here's the math in a more transparent manner:

*** I NEVER LET MY GPU's BREACH 61C, EVER. Only my 8X GPU rigs saw 60-61 & it was the ones I had in the center of the build (naturally). I have REALLY high power fans (used on BTC ASIC MINERS) that were sucking air from those GPU's which was the only way I was able to obtain such stellar results while mining with them. **\*
Mining at "acceptable" heat temps (not acceptable to me, but most of the internet would disagree = 70C) and overclocking accordingly brings in X amount of yields per unit. =
'Tweaking' (underclocking) the GPU's to my parameters reduced my yield per unit from -10-15%, but it SAVED me well over 30-35% in direct electricity consumption, and an unknown amount of passive electricity consumption via creating approximately 20%+ less heat for my AC handler to combat.

I say all this extra stuff not just for anyone interested in mining with their GPU's, but really to answer (in-depth) the apparent questions you people are asking me in PM's. Something else that should help justify my claims of being so conservative should be the fact I only have/used "Platinum and Titanium" rated PSU's. Heat production, power efficiency and longevity of the hardware were ALWAYS my top priority.* . I truly thought Crypto would continue to gain and/or recover and bounce back faster than it did. If this project had maintained positive income for 12 months+, I'd have expanded one of our sites to also cater to GPU mining on a gnarly scale.

Once I have my NAS (& possibly 2nd rig for the firewall) successfully built, I'll be willing/able to entertain selling you guys some/all of the remaining hardware prior to launching on eBay. If there's something you're specifically looking for that I listed having, feel free to PM me with that/those specific item(s). Don't count on an immediate response but what you can count on is me honoring my word in offering whoever asks first right of refusal when the time comes for me to sell this stuff. Fortunately for me, PM's are time-stamped so that's how I'll gauge everyone's place in line. I hope this extra edit answers most of the questions you guys wanted to have answered and if not, sorry I guess. I'll do my best to bring light to anything I've missed out on after I realize whatever that error was/is. The only way anyone is getting first dibs on my hardware otherwise is if they either offer compelling insight into my original questions, or have something I need to trade w/.

THE END (Round#2)

ASICMiner Erupter Video Unboxing and Review

ASICMiner Erupter Video Unboxing and Review submitted by enmaku to Bitcoin [link] [comments]

New people please read this. [upvote for visibility please]

I am seeing too many new people come and and getting confused. Litecoin wiki isn't the greatest when it comes to summing up things so I will try to do things as best as I can. I will attempt to explain from what I have learned and answer some questions. Hopefully people smarter than me will also chime in. I will keep this post updated as much as I can.
Preface
Litecoin is a type to electronic currency. It is just like Bitcoin but it there are differences. Difference explained here.
If you are starting to mine now chances are that you have missed the Bitcoin mining train. If you really want your time and processing power to not go to waste you should mine LTC because the access to BTC from there is much easier.
Mining. What is it?
Let's get this straight. When making any financial commitment to this be prepared to do it with "throw away" money. Mining is all about the hashrate and is measured in KH/s (KiloHash/sec). Unlike the powerful ASICs (Application Specific Integrated Circuit) that are used to mine bitcoins using hashrates in the GH/s and even TH/s, litecoin mining has only been able to achieve at the very best MH/s. I think the highest I've seen is 130 MH/s so far. Which leads us to our next section.
Mining Hardware
While CPU mining is still a thing it is not as powerful as GPU mining. Your laptop might be able to get 1 a month. However, I encourage you to consult this list first. List of hardware comparison You will find the highest of processors can maybe pull 100 KH/s and if we put this into a litecoin mining calculator it doesn't give us much.
Another reason why you don't want to mine with your CPU is pretty simple. You are going to destroy it.
So this leaves us with GPUs. Over the past few months (and years) the HD 7950 has been the favourite because it drains less power and has a pretty good hashrate. But recently the introduction of the R9 290 (not the x) has changed the game a bit. People are getting 850 KH/s - 900 KH/s with that card. It's crazy.
Should I mine?
Honestly given the current difficulty you can make a solid rig for about $1100 with a hashrate of 1700 KH/s which would give you your investment back in about a month and a half. I am sure people out there can create something for much cheaper. Here is a good example of a setup as suggested by dystopiats

Hardware Fundamentals
CPU - Do you need a powerful CPU? No but make sure it is a decent one. AMD CPUs are cheap to buy right now with tons of power. Feel free to use a Sempron or Celeron depending on what Motherboard you go with.
RAM - Try to get at least 4 GB so as to not run into any trouble. Memory is cheap these days. I am saying 4 GB only because of Windoze. If you are plan to run this on Linux you can even get away with less memory.
HDD Any good ol 7200 RPM hard drive will do. Make sure it is appropriate. No point in buying a 1TB hard drive. Since, this is a newbie's guide I assumed most won't know how to run linux, but incase you do you can get a USB flash drive and run linux from it thus removing the need for hard drive all toghether. (thanks dystopiats)
GPU - Consult the list of hardware of hardware I posted above. Make sure you consider the KH/s/W ratio. To me the 290 is the best option but you can skimp down to 7950 if you like.
PSU - THIS IS BLOODY IMPORTANT. Most modern GPUs are power hungry so please make sure you are well within the limits of your power consumption.
MOTHERBOARD - Ok, so a pretty popular board right now is Gigabyte GA-990FXA-UD3 and the ASRock 970 Extreme4. Some people are even going for Gigabyte GA-990FXA-UD5 and even the mighty Gigabyte GA-990FXA-UD7 because it has more PCI-E slots. 6 to be exact. However you may not need that much. With risers you can get more shoved into less.
PCI-E RISERS - These are called risers. They come in x16 to x16 and x1 to x16 connections. Here is the general rule of thumb. This is very important. Always get a POWERED riser otherwise you will burn a hole in your MoBo. A powered rise as a molex connector so that additional power from PSU can be supplied.
When it comes to hardware I've provided the most basic knowledge you need. Also, take a look at cryptobader's website. This is very helpful. Please visit the mining section of Litecoin Forums and the litecoinmining subreddit for more indepth info.
Mining Software
Now that you have assembled your hardware now you need to get into a pool. But before you do that you need a mining software. There are many different ones but the one that is most popular is cgminer. Download it and make sure you read the README. It is a very robust piece of software.

Now that your hardware and software is ready. I know nothing about solo mining other than the fact that you have to be very lucky and respectable amount of hashing power to decrypt a block. So it is better to join pools. I have been pool hopping for a bit and really liked give-me-coin previously known to the community as give-me-ltc. They have a nice mobile app and 0% pool fees. This is really a personal preference. Take a look at this list and try some yourself.
How do I connect to a pool?
Most pools will give you a tutorial on how to but the basics are as follows:
  • Signup for a pool
  • Create a worker for your account. Usually one worker per rig (Yes people have multiple rigs) is generally a good idea.
  • Create a .run file. Open up notepad and type cgminer.exe -o (address_to_the_miningpool:port_number) -u (yourusername.workername) -p (your_worker_password_if_you_made_one). Then File>Save As>runcgminer.run (Make sure the drop down is set to "All Files" and .txt document.) and save in the same folder as cgminer. That's it.
  • Double click on runcgminer.run (or whatever you named it) and have fun mining.
Mining Profitability
This game is not easy. If it was, practically everyone would be doing it. This is strictly a numbers game and there are calculations available that can help you determine your risk on your investments. 4 variables you need to consider when you are starting to mine:
Hardware cost: The cost of your physical hardware to run this whole operation.
Power: Measured in $/KwH is also known as the operating cost.
Difficulty rate: To put it in layman's terms the increase in difficulty is inversely proportional to amount of coin you can mine. The harder the difficulty the harder it is to mine coin. Right now difficulty is rising at about 18% per 3 days. This can and will change since all you miners are soon going to jump on the band wagon.
Your sanity: I am not going to tell you to keep calm and chive on because quiet frankly that is stupid. What I will tell you not to get too carried away. You will pull you hair out. Seriously.
Next thing you will need is a simple tool. A mining profitability calculator. I have two favourite ones.
coinwarz
I like this one cause it is simple. The fields are self explanatory. Try it.
bitcoinwisdom
I like this one because it is a more real life scenario calculator and more complicated one (not really). It also takes increasing difficulty into account.
Please note: This is the absolute basic info you need. If you have more questions feel free to ask and or google it!

FOR IMMEDIATE RELEASE: After Butterfly Labs collapses, engineers find new jobs at 21 Inc.

BEGIN BLOG POST

After Butterfly Labs collapses, engineers find new jobs at 21 Inc.

A bitcoin miner has shipped on time. Yes, that is news. A new venture-capital backed company, 21 Inc., has released a miniature bitcoin miner that they call a "Bitcoin computer". For $399.99, you get a Raspberry Pi, an SHA-256 ASIC board, and a giant fan.
Again, this is news: normally, a manufacturer of bitcoin miners would overdesign and underengineer their equipment, or, if they managed to ship something functional, it would be so poorly engineered -- and over budget -- that it be an explosion waiting to happen and/or priced comparably to a four-door sedan.
21 Inc. has done something remarkable in the Bitcoin world: they started a company that operates like a legitimate business. They're even listed on Amazon.com, a company that's so strict with vendors that Nintendo was kicked off their system for not kissing enough customer ass.
Okay, enough with the praise.

This thing sucks.

The 21.co "computer" certainly deserves a place in the VC world, along with the other products consisting of wild promises and inane use cases. For the price of 4 Raspberry Pi computer kits, you get the following:
(If you have a remote desire to develop applications that use bitcoin, stop here. Go through that list and buy just those items above. You don't need anything else. If you're looking for comedy, or if you're a sucker with too much money, read on...)

Is that all I get for my money?

Those products alone don't allow you to make Bitcoin applications, apparently. You need these things, too:

How about the software demos?

It's difficult to justify developing a $400 computer that can't do much. So, to entice some customers, 21 Inc. included demos that try really hard to make customers feel inspired. Here are just a few things that 21 Inc. claims were totally impossible before their product existed:

What are the real customers saying?

The packaging is slick:
"This @21dotco computer came already opened..."
The hardware is reliable:
"...it must have lost power, which caused my SSH keys to become corrupted."
The software is revolutionary:
"...it will be more expensive to pay for your spotify subscription via your electricity bill, but a lot of people don't care."

I want to buy it anyway!

Go ahead. I won't stop you. Oh, and 21 Inc. doesn't accept bitcoins.

USB Hub for mining

Hey guys,
I am currently trying to get into the bitcoin mining with the hopes of having a steady output of some satoshis. I am quite aware of the current state of the mining business and have run the calculations. So: I am not looking for a quit break even, I just want a steady flow of like 2000 satoshis a day.
To achieve that I have purchased two GekkoScience 2-Pac and I intend to get more over time.
What is missing is the USB hub. I am quite unsure what would be the best pick. What I intend to have is a hub that enables me to have like 5 of these asics pointing upwards and still having at least one, better two, ports free to also run USB fans. And all ports should deliver maximum power (14W) so that I can run the miners on full speed.
Does anyone have any suggestion for such a hub?
Short summary for the hub I want:
I somehow guess that there is not the perfect hub I want. But I hope that at least with the help of you guys I get to the next best fit ;)
Thanks in advance!

Where can I get a good/legit Block Erupter?

So I've been looking into Bitcoin mining, and I thought of picking it up as a hobby. I was looking into getting the Raspberry Pi 3 and getting a few Block Erupters. I've looked on eBay and Amazon, but I'm a little weary because they are sold by third party sellers, and I'm new to this. Is there any verified vendors that I could buy a good Block Erupter from?

Raspberry Pi + ASIC defcoin mining guide

Want to get started mining defcoin with an ASIC and a Raspberry Pi? Does 360 KH/s of mining power sound appealing? Here’s how to do it.
https://pbs.twimg.com/media/Blpj8IvCcAEIStY.jpg
1) Hardware List
-Raspberry Pi Model B
--SD Card
--Micro USB power supply
--Ethernet cable
-Gridseed ASIC
--12V power supply (5.5mm/2.5mm barrel connector)
--USB to Mini USB data cable
The main component is the Gridseed ASIC, which will be doing the Scrypt calculations. The Raspberry Pi will be used as the controller for the ASIC, and will be doing the communication with the mining pool. If you’re not familiar with the term, an ASIC is an Application-Specific Integrated Circuit - basically a chip with a single purpose, like mining crypto currency. Using an ASIC will allow us to mine more efficiently than we would be able to with general purpose hardware.
The ASIC that I’m using is a “300+ KH/s Single Gridseed ASIC Miner”. It looks like a CPU heatsink with a fan attached. There is actually a circuit board with 5 ASIC chips sandwiched between two halves of this heatsink, and has a mini USB connector and a power connector sticking out the side. There are a few places where you can buy these. I bought mine at GAWMiners.com for $130. That was the lowest price that I could find, and I had a good experience buying from them. Use this link, and you can get $20 off of a $200 order (and give me some referral points :-)) GAWMiners. You can also find other vendors by searching for “Gridseed ASIC”. You’ll need a 12V power supply to power the ASIC, and a USB A to USB Mini B cable to connect the ASIC to the Raspberry Pi. I’m using a 60W power supply, which seems to be working fine for defcoin (Scrypt) mining. These ASICs can also mine Bitcoin at the same time, but you may need a beefier power supply if you want to do that.
The Raspberry Pi can be purchased at any number of places- Amazon, SparkFun, AdaFruit, etc. I’m using the Model B because I had one already, and also because it has a built in ethernet port that will make connecting to the internet easy. Make sure to get an SD Card and a micro USB power adapter to get the Pi up and running too.
2) Software
If you haven’t already, download the defcoin wallet from defcoin.org. If you want to do pooled mining, create an account for one of the defcoin pools, such as redbaron.us or whichever other pool you want to mine. Once you’ve created a pool account, make sure to create a worker too (for MPOS pools, that will be under My Account > My Workers). The password for your worker does not have to be the same as the password for your pool account (and it probably shouldn’t be).
Next, download the latest Raspbian image from raspberrypi.org/downloads/ and install the image to your SD card. Instructions for installing the image can be found here. If you are using the dd method on a Mac, make sure to use /dev/rdiskX instead of /dev/diskX - both will work, but rdiskX is much faster. Once you have the image installed, put the SD card in the Raspberry Pi, connect the Pi to your network, and connect the Pi to your micro USB power adapter to power it on. Next, SSH in to your Raspberry Pi with the default username and password pi/raspberry. I use nMap to find the IP address that has been assigned to my Pi. You can also use an HDMI display and a USB keyboard to log in instead of using SSH. After logging in for the first time, run through the wizard that comes up to configure your Raspberry Pi. The defaults are fine for most things, just make sure that you don’t skip the step to expand the filesystem to use the rest of your SD card. If you don’t expand the filesystem, there won’t be enough space for other software.
Once you have Raspbian installed, and have gotten through all of the first login setup stuff (which will likely end with a reboot), log back in to the Raspberry Pi with the pi user. From the command line, run sudo apt-get update sudo apt-get dist-upgrade
There are some stability issues with USB communication between the Raspberry Pi and the Gridseed ASIC. Enabling SLUB debugging seems to resolve this, at least well enough to prevent the Raspberry Pi from freezing every so often. Open the /boot/cmdline.txt file, and add the following text to the end of the line. Don’t add a new line, just add this to the end. You can use vi, nano, or whatever your favorite text editor is to do this.
slub_debug=FP 
Reboot the Raspberry Pi once you’ve added that flag to your /boot/cmdline.txt file.
sudo shutdown -r now 
Log back in with the pi user once the Raspberry Pi is finished rebooting.
The mining software that we’re going to use is a customized version of cgminer that has support for the Gridseed GC3355 chips that are used in our ASIC. There are a number of different mining programs out there, this is just what has been working the best for me so far. First, install git and dependencies needed to compile cgminer.
sudo apt-get install git build-essential libtool libcurl4-openssl-dev libncurses5-dev libudev-dev autoconf automake 
Next, clone the git repository for cgminer-gc3355
git clone https://github.com/dtbartle/cgminer-gc3355.git 
Next, we’ll build cgminer.
cd cgminer-gc3355 autoreconf -i ./configure --enable-scrypt --enable-gridseed make 
Once the make command finishes, we’re ready to run the mining software. You can also run make install if you want to install the software, but running it out of the build directory works just fine. Plug in the power supply for your ASIC, and connect the ASIC to it. Connect the USB cable to the ASIC and to your Raspberry Pi. Run the mining software by running the following command. The -o option specifies your pool URL, the -u option specifies your username and the workername that you set up for the pool, and the -p option is the password for your worker. There are a couple of options available that are specific to the gridseed ASICs, and those will be placed after --gridseed-options. The freq=850 option sets the clock frequency of the ASIC to 850 MHz. There are other clock options available, but 850 seems to be working best for me. I was getting hardware errors at 900, and a lower average hash rate. I am getting about 360 KH/s with the clock frequency set to 850.
sudo ./cgminer -o stratum+tcp://www.redbaron.us:3333 -u Username.Workername -p yourworkerpassword --gridseed-options freq=850 
This command needs to be run with sudo in order to access the USB hardware. You can also create another user specifically for mining, or grant the pi user the appropriate permissions if you don’t want to run cgminer as root. When you run this command, you should see output from cgminer showing that it is communicating with the mining pool, and something showing your hash rate. If you’ve gotten this far, and you’re seeing output from cgminer showing a hash rate, congratulations, you’re mining defcoins with your ASIC! There are just a couple more steps to do if you want to let your Raspberry Pi and ASIC continue mining without needing you to be logged in.
To keep cgminer running after I log out, I am using nohup. You could also use screen instead of nohup. Create a script (startMiner.sh) by running the following commands.
echo “nohup /home/pi/cgminer-gc3355/cgminer --real-quiet -o stratum+tcp://www.redbaron.us:3333 -u Username.Workername -p yourworkerpassword --gridseed-options freq=850 &” > /home/pi/startMiner.sh chmod a+x /home/pi/startMiner.sh 
If you run this command with sudo startMiner.sh, cgminer will run in the background, and will continue running after you log out. If you want to have this run when your Raspberry Pi boots, modify your /etc/rc.local script so that it executes this startMiner.sh script. Your /etc/rc.local file will end up looking like this:
# Print the IP address _IP=$(hostname -I) || true if [ "$_IP" ]; then printf "My IP address is %s\n" "$_IP" fi /home/pi/startMiner.sh exit 0 
That’s it! You should now have a Raspberry Pi controlling a defcoin mining ASIC, that starts mining as soon as it boots up. For more reading, check out some of the links below.

Building a Dual Rig (gaming and mining)

What is your intended use for this build? The more details the better.
I’d like to build a gaming/mining rig. I would like to run 6 graphics cards at one point, might not buy them all outright. So the goal. A gaming computer running the 1070 separately so I can still game and do stuff while the other 5 cards are mining. When im not using the computer, I have the option to put the 1070 to work as well. Is it a stupid idea to combine the two purposes into one super computer? Also, I’m having trouble finding a compatible motherboard and would love suggestions. Finally, I have tried reading on the riser connection info and I’m still not sure. Hopefully those are the correct risers?
If gaming, what kind of performance are you looking for? (Screen resolution, framerate, game settings)
Nothing too crazy. I have done the research on that side of things and the things selected should make me happy.
What is your budget (ballpark is okay)?
$2000-3000 (depending on how many gpu’s I buy at onece)
In what country are you purchasing your parts?
U.S.A (amazon, here is the link my current list. https://www.amazon.com/gp/registry/wishlist/2NAC9YOHISTRI/ref=nav_wishlist_lists_4)
Post a draft of your potential build here (specific parts please). Consider formatting your parts list. Don't ask to be spoonfed a build (read the rules!).
CPU:
AMD Ryzen 5 1600 Processor with Wraith Spire Cooler
Motherboard:
Im not sure!
Memory:
Corsair - Vengeance LPX 16GB (2 x 8GB) DDR4-3000

Looking for a beginner hobby project: Is a Raspberry Pi controlled ASICMiner Block Erupter USB array worth my time?

Hello! I've been wanting to get involved with bitcoin mining for a while and thought that bitcoin black friday was a great time to take the plunge and order some hardware.
I don't have the money to invest in hardware that would actually provide a net profit, but that's not really important as I'm interested in getting involved as a hobby project.
I recently came across this PiMiner Raspberry Pi Bitcoin Miner kit/tutorial and it looks quite interesting. My question for you guys is if you've had any experience or know of any flaws with this setup or even if this is so outdated now so as to render it useless as a miner. I suppose the big unknown for me in this setup is the ASICMiner Block Erupter USB devices.
Is there a better mining hobby setup available in the same kind of price range? Would the raspberry pi controller work with a better alternate USB ASIC miner?
Thanks for taking the time to help me get started with this hobby!

If malicious hackers can pool together tons of phones together to reach considerable hashing power; Can a positive community crowdsource a large batch of cheap USB miners with auto-p2pool configurations? A significant amount of small parts add up to a greater sum!

We now hold the discussion about the danger of GHash's strength, let's use this energy to make a difference.
Let's use frictionless money to make it easy for a bunch of small contributions to make a big difference.
Ghash is popular because it's easy to mine at any amount and get a small payout, even if it doesn't quite break even.
P2Pools offer the same advantage because there is no middleman to collect fees. Yet until P2Pools get larger hashing power, this makes it not advantageous for small miners to individually direct towards P2Pools..
Yet if a bunch of small miners directed towards a single pool, it can make a significant difference
Developers have already created bot-net type applications that use phones to pool together and mine. It has occured on iOS, Android and has been occurring since 2011.
So if developers can do this maliciously, could we use this same mentality in a beneficial way to easily and cheaply secure the network?
Currently you can get small USB miners for a few bucks. And if you want to spend a little bit more, it's easy to get a hub/dock to group more then a few miners together.
Yet even just running one device in the background while online would be useful if many people did this.
So what can we do?
Well the best way to coordinate an effort would be to crowd-fund a kickstarter like campaign to buy a bulk amount of USB miners so that people could spend a few bucks and get a miner or two to give to friends.
It would be great to get a large vendor trying to rid stock could do something like this perhaps?
Ideally I would like to use Lighthouse yet it is not ready. I am unaware of any other decentralized crowd-sourcing applications.
If nothing else arrises then Bitcoin Starter could be a substitute for such a fund.
How many people would be interested in running a small USB miner in the background while your on your computer? If everyone pitched in a buck or two to get a small miner shipped to their house, would you run it?
Please give your thoughts! If you can help please stand up and if your willing to support make that known! If you think this is stupid then say so!
tl;dr: let's see if we can get a community crowdsourced effort to distribute small usb miners to a crowd of people. If they all pointed their dust-amount of hashing power it could add up to a greater sum. If done with a P2Pool it could be a very beneficial action to secure bitcoin's decentralization.

Want to get into Bitcoin and cryptocurrencys and looking for help.

Hi everyone. I'm looking to get into learning about cryptocurrencys and experimenting with mining them. I'm planning on getting a raspberry pi for Christmas and hooking up some USB block Eruptors. I know I won't get a good roi but what would be the best USB device to get? Can anyone tell me some insight on these? And which one I should get.

Someone please proofread what I have written below, so it can be posted on r/environment and other such subreddits.

Here is the title.
Bitcoin requires a tremendous amount of electricity to be maintain, but there are much more environmentally-friendly, alternative cryptocurrencies. Please demand that merchants accept the environmentally friendly alternatives.
Executive Summary:
Large Bitcoin mining operations are now being constructed in places where they unnecessarily squander the least expensive, renewable hydro-electric and geothermal-electric resources. There are very environmentally-friendly, readily-available, alternative cryptocurrencies such as Blackcoin and NXT that do not pose a threat to these precious renewable resources.
The environmentally unfriendly coins that require a lot of electricity to mine are called Proof of Work (PoW) coins. The environmentally friendly alternatives like Blackcoin and NXT are called Proof of Stake (PoS) coins.
The price spike in bitcoin last fall has led to an arms race to adopt electricity-gobbling, specialized mining equipment in the pursuit of corporate mining profits. They were not required to maintain Bitcoin prior to their invention. Specialized mining equipment for a second class of coins, which are similar to Litecoin, another PoW coin, is about to start shipping. This will lead to another large surge in unnecessary corporate mining operations and greatly increase the electrical demand in the race for corporate mining profits.
You can read the long report below.to find out more about the issue, and you can visit blackcoin and NXT at the links below to find out more about our coins. If you have heard enough and just want to do something quick and simple to support our efforts, visit blackcoin and NXT, click on our subscriber button to show your support, and then watch us take on Bitcoin. While you visit the two subreddits, you can judge for yourself which one you think will succeed.
Hopefully, some respected environmentalist will start campaigns to get merchants that already accept Bitcoin and Litecoin to start accepting the environmentally friendly alternatives.
http://www.reddit.com/blackcoin
http://us.reddit.com/NXT/
Electrical requirement to mine PoW coins:
The Bitcoin, Litecoin, and Dogecoin ledger are maintained by miners who compete against each other to see who can first find the next page for their blockchains. Only the miner that wins the race for each ledger page gets paid in coins.
As a result of this competition and the late 2013 price spike, Bitcoin mining corporate startups are popping up in central Washington State as documented in the first link below to take advantage of the inexpensive, renewable hydro-electricity and in Iceland as documented in the second link below to take advantage of the renewable hydro and geothermal resources. If bitcoin continue to expand, it will unnecessarily eat up more and more of these valuable renewable resources

The mining hardware manufacturers are about to start shipping specialized mining equipment that can only mine the Litecoin and Dogecoin type of PoW coins as documented in the two links below. This new front in the mining arms race will gobble up much more precious renewable electricity in the competitive pursuit of corporate mining profits than is currently required to update the ledgers of these coins.

This specialized equipment is prostituting the original bitcoin promise
The tremendously profitable mining of crypto coins that are competitively produced is unnecessarily prostituting the original concept of their inventor, Satoshi Nakamoto. He envisioned bitcoins as being mined on standard personal computers while preforming other useful tasks. Instead, special computer hardware is being manufactured costing upwards to $10,000 apiece which can perform only one task. These individual units are being racked up in warehouses now.
This specialized equipment was not required for Bitcoin prior to its invention and is not required currently for Litecoin and Dogecoin. However, it is coming anyway producing an unnecessary arm race in the pursuit of corporate profits.
These specialized dev ices are energy inefficient in a second ways.
These specialized devices generate so much heat that they require elaborate energy-intensive cooling system for large operation. One of the most elaborate of these cooling systems is documented in the link below for a Hong Cong corporate mining operation that emerges the energy-wasting equipment in boiling goo to keep it cool. Thus, not only does it take electricity to run the equipment for these large operations, but more to keep it all cool.

PoS coins are the environmentally friendly alternative.
In contrast, the ledger pages of coins like Blackcoin and NXT are generated by stakeholders who cooperate to perform the task which are being done on standard multitasking computers. Many of these computers would be running anyway as originally envisioned by the inventor of the blockchain.
If you have heard enough and just want to do something quick and simple to support our efforts, visit blackcoin and NXT, click on our subscriber button to show your support, and then watch us take on Bitcoin. While you visit the two subreddits, you can judge for yourself which one you think will succeed.
Hopefully, some respected environmentalist will start campaigns to get merchants that already accept Bitcoin and Litecoin to start accepting the environmentally friendly alternatives.

Clever mining multi mining pool with usb asic stick ?

Hi all. As a novice miner I was just wondering if anyone has had any success mining on http://clevermining.com/ with a USB ASIC such as this http://www.amazon.com/gp/aw/d/B00CUJT7TO?pc_redir=1411211420&robot_redir=1 . My understanding is that it is uneconomical to mine bitcoin alone on a USB ASIC such as this at this time but I'm not sure if this is the case with multi coin sites. Thanks guys !

Litecoin mining with a Raspberry Pi: Is it possible?

I'm not looking for anybody telling me it'll be horribly inefficient. I already know that. I'm mainly just doing this for a little bit of fun. I know Bitcoin rigs are possible, but what about Litecoin? I found these USB ASIC miners on Amazon and I could just put it on a USB hub and power it with the Pi, but are there any mining programs that'll work with it?

Eobot.com FAQ

FAQ https://www.eobot.com/new.aspx?referid=94984
General Questions What is a Bitcoin? Good question; see www.bitcoin.org for more information.
What are your options to withdraw? We currently only allow withdrawals in BTC/LTC/BC/NMC/DOGE/XRP/DRK/RDD/BTS/CURE/PPC/NXT/SYS.
Why can't I deposit or withdraw "real currency", aka fiat (USD/EUJPY/GBP/CNY/RUB/etc.)? Due to international law, we do not allow you to deposit or withdraw fiat currencies. In the USA, there are MSB and FinCen regulations; in Europe, certain countries have banned cryptocurrencies, and in China, the banks aren't allowed to transfer cryptocurrencies. The laws may change in the future.
Why does my "Total Cryptocurrency Value" go down? This is because that display is tied to the exchange rates on other websites. Also see this user generated YouTube video for more information: https://www.youtube.com/watch?v=GucqlMuIXMg
Are their any fees to join or monthly fees? No fees.
Do you speak Spanish/Russian/Chinese? No, only English, but Google Translator works well.
What are the maximums/minimums for withdrawing? There are no maximums. The minimums are small, see the withdraw page for details.
Where can I see the terms and conditions? Please click here for terms and conditions.
Where can I see the privacy policy? Please click here for privacy policy.
Are you hiring? We are always looking for quality talent. If you would like to contribute, then please send your cover letter and resume to [email protected].
Do you have a bug bounty program? Yes, we pay for bugs, so contact us for details or visit us at CrowdCurity.com and submit bugs there!
Do you perform off-chain transactions? No we do not. All cryptocurrencies are sent, usually including miner fees, and can be seen on the blockchain for that respective cryptocurrency. This helps secure the network, makes our transactions transparent, provides an easier way to debug and track down coins, and reduces the chance for fraud. An off-chain transaction would be like what Coinbase could do if both users are Coinbase users and they change coins from one email to another, mark it in the database, and Bitcoin is never actually sent from one wallet to another.
Why does my balance reset after refreshing the page or changing cryptocurrencies? The server updates every 60 seconds and the balances you see updating in real-time are performed with Javascript. If you change pages quickly, or choose a new cryptocurrency, then it will look like it is resetting. However nothign is lost, as whatever cryptocurrency it is set at when the server updates will get the past 60 seconds of mining results.
Help! My account was hacked and withdraws are being made? Eobot is a secure site and has never been compromised. If your account was hacked, then you should change your password, turn on 2FA, and turn on email notifications. There are many unscrupulous Bitcoin sites, and most likely, you used the same password on another site. Never re-use passwords!
Do you have any wallpapers? Yes, you can download wallpaper1 or wallpaper2. Feel free to send us your own creations.
What does Eobot stand for? We have heard everything, let us know your favorite, including: Earn Online Bot, Earn Online Bitcoins Online Tool, Earn Online By Our Tech.
Is this legal? We cannot provide legal advice; make sure cryptocurrencies are legal in your jurisdiction before continuing to use Eobot.
Cloud Mining Questions What are the Cloud Mining fees? For electricity and maintenance, we currently charge a fee of 65% for SHA-256 and 65% for Scrypt. These values will change as difficulty increases, exchange rates change, and newer ASICs come online. These fees are better than our competitors, for instance CEX.IO charges $0.105 per GHS, which is a 81% fee! While GAW charges a 96% fee at current prices!
How long are the Cloud Mining rentals and contracts? Prior to October 11 2014, GHS/KHS contracts had no expiration. Old contracts are not affected. New contracts and rentals, mined or purchased after October 11 2014, are now limited in term for 5 years going forward. See your History tab for expiration dates.
Can I sell my Cloud Mining? No, you cannot sell the cloud shares at this time. This is because we own the hardware and do not want to be stuck if everyone decides to sell at once.
Can I buy Cloud Mining with credit card/USD? Yes, but please keep in mind you cannot sell or convert the Cloud Mining.
Can I buy Cloud Mining with cryptocurrency? Yes, deposit the cryptocurrency and then convert it to your choice of Cloud Mining.
What are the maximums/minimums when making a credit card purchase to buy Cloud Mining? The minimum is 1.0 GHS and 10.0 KHS and there is no maximum at this time.
Can I buy a Cloud Mining that mines in Scrypt? You can use the Cloud Mining SHA-256 hashing power to mine other currencies by automatically converting them as you mine, but the earnings will still be tied to SHA-256/Bitcoin difficulty, not Scrypt/Litecoin difficulty.
What is the difference between Cloud Mining SHA-256 and Cloud Mining Scrypt? One is tied to the difficulty in mining SHA-256 cryptocurrency (Bitcoin) and the other is tied to the difficulty in mining Scrypt cryptocurrency (Litecoin). This means that if history is any indication of the future, then the Cloud Mining Scrypt won't decrease as fast as the Cloud Mining SHA-256.
What does 1 instance of Cloud Mining SHA-256 and Cloud Mining Scrypt equal? 1 of Cloud SHA-256 equates to 1.0 GHS of SHA-256 mining power, while 1 of Cloud Scrypt equates to 1 KHS of Scrypt mining power.
Can I change the pool that my Cloud mines on? No, you cannot; this may change in the future.
What hardware is behind the Cloud Mining? The hardware varies from custom ASICs to GPUs. The ASICs are behind the SHA-256 and the GPUs are behind the Scrypt.
Can I RDP (remote desktop) into my Cloud Mining? No, you cannot at this time; we will run the servers for you.
What is the Cloud Mining Pre-Order? These are the same as the other Cloud Mining, but they will start mining on a later date. For instance, a Cloud Mining Pre-Order October 2014 will start mining on October 1, 2014.
Software/Miner Questions Why is it stuck on "initializing...please wait 5 minutes"? We recently changed our Scrypt pool, so this messge will show and the stats and speed won't show under your account. See pool info page for more info.
Why does it show as a trojan/virus? This is a false-positive that many of the popular antivirus programs report. For now you can ignore it, or try another free antivirus, like Microsoft Security Essentials. Hackers use something similar programs to make money off of people's computers, so that is why it shows up as a virus.
Why does Chrome block the download as malicious? This is another false-positive. Simply, go to your Chrome settings, scroll to the bottom and click on "Show Advanced Settings". Go to the Privacy section and uncheck "Enable phishing and malware protection". You will only do this temporarily. Then proceed to download our software. Then return to your privacy settings and recheck Enable Phishing to further protect you.
Do you have a Mac or Linux version? Yes, see the Pool Info under the Account page.
How do I use cgminer? See this English PDF tutorial for cgminer, or Spanish version, created by one of our members, for a simple walk-through.
How can I increase the speed? Important to increase speed: The default cgminer settings do not include hardware specific flags, which you may find here in the Litecoin Mining Hardware Comparison. Failing to use the proper flags can result in performance decreases in excess of 50%.
What do the intensity settings relate to? This is the same as cgminer flag --intensity. Low is 11, normal is none, high is 15, very high is 17, extreme is 19.
Can I use one account for multiple computers on same IP address? Yes, it will add your speed/rates together, you can use as many computers as you want.
Can I connect to the pool manually, through cgminer or bfgminer? Yes, see the Pool Info under the Account page.
Do you use Bitcoin and Litecoin? Yes, we are the easiest miner to use with BTC and LTC and convert on the backend automatically.
What do you use on the backend? We use cgminer, bfgminer, pooler's CPU miner, and a variety of pools.
Can I mine any cryptocurrency? Yes, regardless if you use SHA-256 or Scrypt (BTC vs LTC mode), you can earn and mine any cryptocurrency.
Can I use an ASIC? Yes, simply choose the option and run as GPU mode. Devices that work with bfgminer will work, for instance USB Block Eruptors or Butterfly Labs ASICs. You can also contact us for pool information for other ASICs.
What is the best graphics card/computer to buy? Either use a high end ATI Radeon card, or buy one of the USB Block Eruptor devices on Ebay/Amazon or a similar online store.
What drivers do I need for USB mode? http://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx
Why doesn't GPU mode work? You may need to download the OpenCL drivers; get them from here: http://developer.nvidia.com/opencl
Where can I get the .NET framework? Try Windows Update, or use Microsoft Web Platform Installer.
Can I use a proxy server? Yes, edit intensity.txt and put the details in there, for example, add "--proxy=http://mycompany-http-proxy:8080"
Where can I download the software? Download from link here
Can I use custom flags/change intensity? Yes, you can put in whatever custom flags/parameters/arguments you want. Edit the "resources/intensity.txt" file. Put in whatever you want, like for GPU mode: "--intensity 12 --shaders 1024" or for CPU mode (number of threads): "-t 32"

Side effect or rising bitcoin prices: rising bitcoin mining hardware prices

A month ago you could pick up USB ASIC hardware for less than $40/US. Now the price has risen to over $80/US.
I think it's an interesting indicator, and a possible indicator of how many people are flocking to Bitcoin mining late in the game.
