Open-Source FPGA Bitcoin Miner and ASIC conversion...

Hey Everyone,
So there has been a lot of talk about FPGA and ASIC miners recently, and I've been doing some of my own research. FPGA's are fully programmable, and mainly used in R&D where ASIC's cannot be programmed - but are cheap and have the potential to out preform FPGA's.
Here's where it gets interesting. There are multiple companies that do FPGA-to-ASIC migrations for this exact purpose. The "R&D lab" has a stable setup with their FPGA and want to get it into production. It would make little sense to use expensive and slower FPGA's, especially when the code (HDL) has been finalized. This is where these migration companies come in...
Now this is what I'm thinking, we already have the Open-Source FPGA Bitcoin Miner HDL - so what's stopping us with going into full production mode and getting our OWN ASIC's???
I've come across multiple companies that do this (it seems pretty common practice) such as this one that even offers pin compatibility which would make our lives even easier:
Any input is welcomed! I haven't messed around with FGPA's in 13 years so I'm probably off on a few things. Feel free to fill in the holes!

Best $100-$300 FPGA development board in 2018?

Hello, I’ve been trying to decide on a FPGA development board, and have only been able to find posts and Reddit threads from 4-5 years ago. So I wanted to start a new thread and ask about the best “mid-range” FGPA development board in 2018. (Price range $100-$300.)
I started with this Quora answer about FPGA boards, from 2013. The Altera DE1 sounded good. Then I looked through the Terasic DE boards.
Then I found this Reddit thread from 2014, asking about the DE1-SoC vs the Cyclone V GX Starter Kit:‬ (I was also leaning towards the DE1-SoC.)
Anyway, I thought I better ask here, because there are probably some new things to be aware of in 2018.
I’m completely new to FPGAs and VHDL, but I have experience with electronics/microcontrollers/programming. My goal is to start with some basic soft-core processors. I want to get some C / Rust programs compiling and running on my own CPU designs. I also want to play around with different instruction sets, and maybe start experimenting with asynchronous circuits (e.g. clock-less CPUs)
Also I don’t know if this is possible, but I’d like to experiment with ternary computing, or work with analog signals instead of purely digital logic. EDIT: I just realized that you would call those FPAAs, i.e. “analog” instead of “gate”. Would be cool if there was a dev board that also had an FPAA, but no problem if not.
EDIT 2: I also realized why "analog signals on an FPGA" doesn't make any sense, because of how LUTs work. They emulate boolean logic with a lookup table, and the table can only store 0s and 1s. So there's no way to emulate a transistor in an intermediate state. I'll just have play around with some transistors on a breadboard.
UPDATE: I've put together a table with some of the best options:
Board Maker Chip LUTs Price SoC? Features
icoBoard Lattice iCE40-HX8K 7,680 $100 Sort of A very simple FPGA development board that plugs into a Raspberry Pi, so you have a "backup" hard-core CPU that can control networking, etc. Supports a huge range of pmod accessories. You can write a program/circuit so that the Raspberry Pi CPU and the FPGA work together, similar to a SoC. Proprietary bitstream is fully reverse engineered and supported by Project IceStorm, and there is an open-source toolchain that can compile your hardware design to bitstream. Has everything you need to start experimenting with FPGAs.
iCE40-HX8K Breakout Board Lattice iCE40-HX8K-CT256 7,680 $49 No 8 LEDs, 8 switches. Very similar to icoBoard, but no Raspberry Pi or pmod accessories.
iCE40 UltraPlus Lattice iCE40 UltraPlus FPGA 5280 $99 No Chip specs. 4 switchable FPGAs, and a rechargeable battery. Bluetooth module, LCD Display (240 x 240 RGB), RGB LED, microphones, audio output, compass, pressure, gyro, accelerometer.
Go Board Lattice ICE40 HX1K FPGA 1280 $65 No 4 LEDs, 4 buttons, Dual 7-Segment LED Display, VGA, 25 MHz on-board clock, 1 Mb Flash.
snickerdoodle Xilinx Zynq 7010 28K $95 Yes Xilinx Zynq 7-Series SoC - ARM Cortex-A9 processor, and Artix-7 FPGA. 125 IO pins. 1GB DDR2 RAM. Texas Instruments WiLink 8 wireless module for 802.11n Wi-Fi and Bluetooth 4.1. No LEDs or buttons, but easy to wire up your own on a breadboard. If you want to use a baseboard, you'll need a snickerdoodle black ($195) with the pins in the "down" orientation. (E.g. The "breakyBreaky breakout board" ($49) or piSmasher SBC ($195)). The snickerdoodle one only comes with pins in the "up" orientation and doesn't support any baseboards. But you can still plug the jumpers into the pins and wire up things on a breadboard.
numato Mimas A7 Xilinx Artix 7 52K $149 No 2Gb DDR3 RAM. Gigabit Ethernet. HDMI IN/OUT. 100MHz LVDS oscillator. 80 IOs. 7-segment display, LEDs, buttons. (Found in this Reddit thread.)
Ultra96 Xilinx Zynq UltraScale+ ZU3EG 154K $249 Yes Has one of the latest Xilinx SoCs. 2 GB (512M x32) LPDDR4 Memory. Wi-Fi / Bluetooth. Mini DisplayPort. 1x USB 3.0 type Micro-B, 2x USB 3.0 Type A. Audio I/O. Four user-controllable LEDs. No buttons and limited LEDs, but easy to wire up your own on a breadboard
Nexys A7-100T Xilinx Artix 7 15,850 $265 No . 128MiB DDR2 RAM. Ethernet port, PWM audio output, accelerometer, PDM microphone, microphone, etc. 16 switches, 16 LEDs. 7 segment displays. USB HID Host for mice, keyboards and memory sticks.
Zybo Z7-10 Xilinx Zynq 7010 17,600 $199 Yes Xilinx Zynq 7000 SoC (ARM Cortex-A9, 7-series FPGA.) 1 GB DDR3 RAM. A few switches, push buttons, and LEDs. USB and Ethernet. Audio in/out ports. HDMI source + sink with CEC. 8 Total Processor I/O, 40 Total FPGA I/O. Also a faster version for $299 (Zybo Z7-20).
Arty A7 Xilinx Artix 7 15K $119 No 256MB DDR3L. 10/100 Mbps Ethernet. A few switches, buttons, LEDs.
DE10-Standard (specs) Altera Cyclone V 110K $350 Yes Dual-core Cortex-A9 processor. Lots of buttons, LEDs, and other peripherals.
DE10-Nano Altera Cyclone V 110K $130 Yes Same as DE10-Standard, but not as many peripherals, buttons, LEDs, etc.


icoBoard ($100). (Buy it here.)
The icoBoard plugs into a Raspberry Pi, so it's similar to having a SoC. The iCE40-HX8K chip comes with 7,680 LUTs (logic elements.) This means that after you learn the basics and create some simple circuits, you'll also have enough logic elements to run the VexRiscv soft-core CPU (the lightweight Murax SoC.)
The icoBoard also supports a huge range of pluggable pmod accessories:
You can pick whatever peripherals you're interested in, and buy some more in the future.
Every FPGA vendor keeps their bitstream format secret. (Here's a Hacker News discussion about it.) The iCE40-HX8K bitstream has been fully reverse engineered by Project IceStorm, and there is an open-source set of tools that can compile Verilog to iCE40 bitstream.
This means that you have the freedom to do some crazy experiments, like:
You don't really have the same freedom to explore these things with Xilinx or Altera FPGAs. (Especially asynchronous circuits.)


Second Place:

iCE40-HX8K Breakout Board ($49)

Third Place:

numato Mimas A7 ($149).
An excellent development board with a Xilinx Artix 7 FPGA, so you can play with a bigger / faster FPGA and run a full RISC-V soft-core with all the options enabled, and a much higher clock speed. (The iCE40 FPGAs are a bit slow and small.)
Note: I've changed my mind several times as I learned new things. Here's some of my previous thoughts.

What did I buy?

I ordered a iCE40-HX8K Breakout Board to try out the IceStorm open source tooling. (I would have ordered an icoBoard if I had found it earlier.) I also bought a numato Mimas A7 so that I could experiment with the Artix 7 FPGA and Xilinx software (Vivado Design Suite.)


What can I do with an FPGA? / How many LUTs do I need?

60 BTC tip for VHDL ASIC working design

Continued from
You guys convinced me that the best way to achieve the goals stated in the previous post is to design the ASIC chip from scratch, or based on a FPGA VHDL design, instead of reverse engineering it.
Here is a reference to a relevant FPGA design opensource resource :
And also the original FPGA which the Avalon ASIC is the evolution for, and for which there are schematics and documentation available at :
So i'm offering a 100 BTC tip to anyone who can put out a VHDL Bitcoin miner working design conforming to the avalon specs at
Thank you in advance for your response! This is an amazing community!
EDIT Opensourcing the ASIC chip design is indeed something that will happen according to our roadmap and milestones reached. At any further revision of the chip the previous generation would be opensourced.
Added link to FPGA github resource mentioned in the comments.
Since i received several critics regarding the size of the tip/bounty, i have modified the amount a bit. Thank you!

FPGA Mining

A FPGA opensource miner has just been released running at 80Mhps but at a cost of $585. The efficiency is stated below quoted from a post in the thread.
At 80 MHps, I will need at least 3 of these to achieve a single 5830 hashrate. That is $595.-x 3 = $1785.- at full price, vs. $190.- for the 5830.
Giving the 5830 is consuming $11.- a month in electricity, and assuming this board will consume zero electricity, it will take more than 145 months, or 12 years to recover the investment, always comparing to a 5830.
In this thread, someone mentioned he is doing 210Mhash/sec after some optimization but he will cease public posting of his development.
Apologies but no more development information will be posted. I've been offered a 25% share from someone that owns 2 FPGA clusters. If you haven't seen that type of hardware before think a 156 FPGAs per machine.
From those posts what we can understand is that the factors that affect FPGA now are high procurement cost, low running cost and ease of scalability . What this means is that with the increasing total hash rate of the network (30Ghash/day last difficultly adjustment) the question becomes when would the difficulty render GPU inefficient in contrast to running cost?
Remember to take into account FPGAs are usually run in clusters and even though it would not be beneficial to buy one outright, those who have access to FPGA are the first movers and eventual dominant forces of the mining market.
Of course, in the end, ASIC is where it's at. Anyone? =D
Edit: read more stuff, added info.

3 Types of Bitcoin Mining Hardware

There are two options for mining Bitcoin: cloud mining and hardware mining. While cloud mining has to do with mining remotely without physical mining equipment, hardware mining comes with the full package. Most people prefer to set up a Bitcoin miner as it is more profitable than cloud mining in some cases. If you want to set up your Bitcoin miner, you need to know that it is expensive and upgraded versions are made now and then.
Types of Bitcoin Mining Hardware
  1. CPU/GPU Bitcoin Miners
Although this was the first type of Bitcoin mining hardware accepted into the mainstream, it is now considered the least powerful. You’d be using the CPU of your computer to mine Bitcoins. By adding GPU hardware to your computer, you will be able to enhance the hash rate. However, the Bitcoin mining difficulty has increased so much that people can hardly make any profit for CPU/GPU mining.
  1. FPGA Bitcoin Miners
FPGA stands for Field Programmable Gate Array. It is a circuit designed for configuration after building. This allows hardware manufacturer to buy chips in volumes and customize the chips for Bitcoin miningbefore installing them into their equipment. The performance of this hardware is far better than that of CPUs and GPUs.
  1. ASIC Bitcoin Miners
Of the three types of Bitcoin miners, ASIC is the best. ASIC stands for Application Specific Integrated Circuits. They are designed specifically for the sole purpose of mining Bitcoins. They are extremely fast and consume relatively low power compared to the others. Although they are expensive, the miming speed of these miners is mind-blowing

How does Robinhood make money? – Tue Apr 17 If you want to set up your Bitcoin mining rig, the best system for you should be the one you can afford and make a profit from.

Having trouble with FPGA(Altera DE2 board) mining

I've been trying to mine with a DE2 board, and it keeps giving me this error
ERROR: Unable to getwork. Reason: key "result" not known in dictionary.
Anybody have any idea why?
I'm using The Open Source FPGA Bitcoin Miner
I have a regular DE2, not a DE2-115, and I managed to get the correct sof file to set it up (can't remember where I got it from though), so that's probably not the problem here..
I've tried using the mining_proxy, as someone suggested on the same fourm, but I can't seem to get it to work at all.. In fact, I have no idea how I was supposed to make it work; I even tried the proxy with my GPU and still couldn't get it to work.
the .bat files I used were
mining_proxy -nm -o -p 3333
cudaminer.exe -o http://localhost:8332/ -O username:pass
Maybe if I get this working correctly, it'll actually work this time?
It would be awesome if someone could help me out here, I don't know much about mining in general as I started out only yesterday.
Thank you in advance!

Battlecoin [BCX]: a new (and ambitious) game changer in the world of cryptocurrency - Interview with JackofAll

"When it gets too hard for mortals to generate 50BTC, new users could get some coins to play with right away." - Satoshi Nakamoto, 2010
Time goes faster when one talks about IT but, when talking about cryptocurrencies, time goes faster yet.
How long have passed since we’ve heard of mythic characters from the beginning of cypherpunk era – like John Gilmore, Eric Hughes and Tim May – and those from the early days of digital currency of Wei Dai, Satoshi Nakamoto (real or not, it doesn't matter) and others, passing by the current Bitcoin and other cryptocurrencies whales – that now are experts or well established entrepreneurs – to us, the Fourth Generation?
Twenty-two years.
However, if we consider that the real deal has only begun on 2009 with Satoshi’s Genesis Block, then the perspective of the quantic leaps we are giving become clearer.
2009 - Satoshi Nakamoto deployed tools and strategy to people regain control
2011 - FPGA Bitcoin Miners appear. Regular GPU miners start to struggle more and more for Bitcoins
2013 - ASIC miners enters the market, and an official Bitcoin mining industry arises, taking small miners – regular people – completely out of the Bitcoin mines, forcing them to mine – and to create – many different altcoins with many different purposes.
2014 - Now, five years after Bitcoin Golden Dawn and almost four years after the white ninja Satoshi’s disappearance, another cryptowarrior arises on battlefield to give (hash) power back to the people.
Was Satoshi foreseeing what was about to come? However, this time, not so philanthropically…
Meet JackofAll, Head Developer of Battlecoin [BCX].
Andre Torres: Jack, are you there?
JackofAll: Yes.
AT: Thanks for talking to and also to (in Portuguese and Spanish). Shall we begin?
JoA: Yes.
AT: With the ASIC TH/s mining hardware invading Bitcoin mining pools as FPGA once did - and are about to do again, this time in Litecoin mines - common people are getting more and more trouble to mine big cryptocurrencies and have ROI.
The cryptomines, crowded with dead and injured miners, have become - literally - a battlefield.
Now is my question, why the name Battlecoin?
JoA: Battle coin is by design of course. Just like everything that we do. And yes, it is for the reasons that you might think. It has become a "Battle” out there to get coins made, to get coins listed and just to be able to mine against the early guys that have all the hardware. So I came up with the name Battlecoin rather solidify what we are doing. We are battling for hashpower and BCX will give the opportunity for anyone (with enough battlecoins) be able to have control of a comparable amount of hashpower that the elite crypto whales have.
We also have a little controversy that surrounds us, as some people would say that we are waging war on altcoins by the nature of what we are doing. People will Battle it out to keep control of our hashpower. It could possibly lock some of the weaker coins ...for instance if we are paid to switch to a coin with low difficulty or one that has low network support on average and we are paid to drive the difficulty up .
There are several things that could happen to some coins... Bad things they might not react how the developers have intended. We might fork coins or even lock coins up when our pool stops mining. So not everyone will like us. So here again another battle to try to walk a public relations line. So in short, I would say that Battlecoin represents all of the battles we have gone through and the many more we have in front of us.
We also have other app ideas that would complement the Battlecoin Brand.
AT: Nice :)
Do you watch anime/read manga, Naruto, more specifically? I mean, Battlecoin project is like an army that will, more than just fight, direct the ways of the wars by influencing/disrupting the market by its own will or by contract?
JoA: Actually I do not, as my schedule does not permit such luxury... but my sister does and as a matter of fact she is a very good cartoon artist and most of her subjects are anime. But relation to any specific object or character is purely coincidental.
I will check it out now though =)
AT: I did that relation to Naruto because there is an organization called Akatsuki, and when you replied my first question, it immediately reminded me of them.
JoA: Nice.
AT: However, you did not reply my previous comment... but then I've got the idea correctly... or not?
JoA: Ask the question again and I will try to sum it up… (Jack remembers the question) “Battlecoin project is like an army that will, more than just fight, to direct the ways of the wars by influencing/disrupting the market by its own will or by contract?”
Yes exactly. It will do all of the above it will have a big influence in the market.
AT: I was just thinking about that.
JoA: Yes that is why such a controversy. There are people that don’t want to see this happen but I feel it is part of altcoin evolution.
AT: indeed. It’s like a new powerful ninja/warrior coming into the game, not seen since Satoshi's era.
JoA: Yes... You Get it.
AT: What about competitors? Is there anyone on the same level?
JoA: No. Not really. We are the only ones that I know of that is taking the multipool to this level. They have the hashpower but they do not let the public decide where to put it. They just follow an algorithm that directs to "most profitable" coin. We will give that, plus add some human power to the equation. As far as I know, we are the only one that is working on having a voting system that controls it.
Giving it that human element that other concepts lack.
AT: But it needs more than a swallow to make a summer... You do have some other strong companions, don't you? Also, you talk as "we".
Are there other Generals in Battlecoin army? Who are they?
JoA: Well, it was originally my concept but I could not embark on this project alone. I have one partner that is above the board Mr. Big. We Kind of met through a mutual acquaintance and formed a solid partnership. Mr. Big has several projects that I am not sure of what I have liberty to discuss but I do know one of those projects will be to provide hosting services and as I said before we are working on some application ideas that are still in concept.
I also have a private backer that would like to remain nameless. In addition, I have a few consultants that I work with too and I consider them a part of the team of course.
Our team is growing daily... and you have to remember this is a project that involves the community, so in my eyes they are part of US too.
AT: Yes... or all the strategy developed might go to the floor, since the project will require a LOT of hashpower...
JoA: I am hoping to have camaraderie developed and rivals be formed over this concept. I want people to be talking in War rooms about what coin they want to hit... Strategy for pump and dump coins, etc.
Yes, it will require a lot of hashpower and I hope that people will want to give us that hashpower, because they will get paid top $$ for that.
We won’t be making the revenue from the battlecoins that get spent... That money will be split between the miners in our pool as subsidy to make sure that they continue to make as much or more than they could make mining anywhere else.
AT: Now that the strategy has been covered and we are entering more into the battlefield grounds, when will the battles begin?
JoA: I cannot confirm a release date for Phase 3, which includes the "arena", but Phase 1 Will be open to the public on this Friday 9 minutes after 9 pm. The wallets will be linked on our website first then we will post on BCT and then we will have a Big giveaway starting shortly after to kick it all off.
I will also provide a mirror on Google drive. We should have a Block crawler and a faucet too, if all goes well.
AT: That sounds great. Andre Torres: So, during Phase 1, you will gather your ranks that will battle when Phase 3 starts... On what consists Phase 2?
JoA: Phase 2 will be where we determine the market value of a Battlecoin. It will need to be listed on an exchange to determine the FMV of the coin. We originally were going to dictate the price on our own exchange but we feel like to keep with the nature of crypto it would be best to let the free market decide. We have been in touch with a couple of exchanges that have interest in our idea as ours is one that would form a close relationship and provide an elevated amount of trade volume with the exchange that carries our brand .
AT: Battlecoin already have an exchange of preference? On the other hand, perhaps some exchange have already manifested interest on trading BCX with exclusivity?
JoA: I wish to decline to answer as negotiations are still going on.
AT: A wise decision. (laughs)
AT: Now, from the battlefield to the weapons of combat... could you talk a bit about the mechanics of Battlecoin?
JoA: It is pretty straightforward. We did a small pre-mine to make sure we had enough coin for the 3rd phase. And we are doing a small bonus block mine in the beginning to give all of our supporters plenty of Battlecoin to play with for the phase 3 open. And then from there it is a solid 50 coins a block every 2min we should find a block...
Difficulty adjusts every block with a 10-block look back. I think this will provide a very smooth operating coin providing plenty of coin to the market for the use of our services.
There will be a proof of stake 1% every 10 days with maturity of 20 days. This is to reward the users for holding our coin so they will have plenty to use when the time comes.
AT: As we finish this interview, any other comments you might like to add?
JoA: I think we have covered quite a bit and we have much more to come in the future. I appreciate all of your time and hard work!
AT: Me too. I am very glad of this talk and for having the opportunity of talking beforehand with the mastermind of a project than can be a huge game changer on cryptocurrency world.
JoA: Yes, it is nice to be able to talk directly to the people that make it happen. I wish I had back in the day... lol. The advantage and tools that the newcomers have…
AT: Let us make new days :)

FPGA mining?

Has anyone thought about using FPGAs to mine litecoins? In particular, I was thinking about Xilinx Vertex FPGAs, which have large amount of block RAM, which might be useful for the litecoin RAM-intensive hashing algorithm. However, they don't have enough block RAM to saturate the logic with hash units, so you'd still need a board with off-chip RAM, although not much. On the downside, they are much more expensive than the Spartan FPGAs most FPGA Bitcoin miners seem to be using.

Mining Question: Is FPGA mining completely worthless already, or when the ASICs truly ship?

I've been really wanting to get into bitcoin mining but cant bring myself to invest in a Butterfly labs unit with a horrible prediction as to the shipping date as well as not being able to even know where i am in the pre-order lineup.
I could very well be 20,000th in line and never have a chance of getting my bitcoin paid back. I have no doubt it would make profit in dollars, but if i spend 15 bitcoins, I want to make back at least 15 btc.
So my question is about FPGA boards. It looks like the market is largely dead for actual FPGA bitcoin miners, but many generic FPGA boards (if I programmed them and figured out how to get them mining) are relatively inexpensive. I was curious if anyone knew where you could get directions for programming FPGA boards. I dont need the fancy ones that are mini computers, just what I need to make it mine.
Does anyone know a way to get a few GHash out of some regular FPGA boards instead of ones prepackaged to mine bitcoin, and subsequently sold for prices reflecting their Network Hash Rate?

[WTS] Altera DE2-115 FPGA board - capable of 100 MHash/s with incredibly low power!
Can count the number of times I've used this on one hand, never really bothered setting up a mining setup after my video card one - as I had planned to do with this board.
I can ship internationally for an extra 5 BTC.
Selling for a total of 30 BTC (shipping to Australia inclusive) or 35 BTC with shipping internationally inclusive. Worth $595 in non-crypto currency!
Open to negotiation!

would bitcoin mining with an FPGA (or multiple) be feasable?

so i was thinking a bitcoin asic is only good for one generation of asics and if a new one comes out they are no longer profitable, then i had the idea to use an fpga and becasue an fpga is basically as fast as an asic there shuld be no difference in berformance and once a new generations of asics comes out you would only be one firmware update away from being profitable again. do you guys thinck?

Creating a BitCoin or any Crypto miner on an FPGA- How tough is it?

I have a small project to implement using SoC, and I was thinking of creating a crypto miner using microblaze. However, the deadline for this project is around ~3-4 weeks, I have decent VHDL experience and have used microblaze before.

Are there any beginner resources on where I can read how I can design and create my own crypto miner?

Can anyone explain the bitcoin source code?

I have a friend that want to try mining bitcoin and I want to help him. I understand the operating principle of bitcoin, but how come there exists bitcoin and miners (such as cgminer)? Could anyone provide a guide to reading the source code so that I can understand it on a deeper level?
P.S. I tried to look into the make file, but I am not an experienced programmer so I could not understand much, is that the right direction?

Effects of ETC moving to SHA3

0xBitcoin might experience some benefits from ETC's recent decision to go to SHA3.
For one thing, if ETC developers turn their minds toward SHA3 GPU mining, it seems likely that they'll be very interested in the optimization work already done by Lt. Tofu and Azlehria on Cosmic and Nabiki. But they may also spot additional optimizations, which could most likely be ported back into our miners!
For another thing, since ETC has a larger community than 0xBitcoin's, it's likely that they have people with very diverse skills. As they turn their minds toward SHA3 on FPGAs, I anticipate they will be choosing FPGA boards and writing software for them that probably will not be very difficult to alter to mine 0xBitcoin! Practically speaking, this may result in a new era of mining where a respectable hash rate can be achieved with much less electricity expense.
Basically, if people with EE or hardware development backgrounds in the ETC community pin down some of the variables involved, like development board, it seems very likely that we will be able to get FPGAs mining 0xBitcoin quickly.
We recently exchanged some nice words with Alex Tsankov. He revealed he is doing work that may allow merge mining ETC and other projects like 0xBitcoin. I don't know how good this will be, but it's hard for me to see how this could be a bad thing. It's really great to have nice words from Alex, because he seems like a very smart dude who is very open to collaboration.
I have joined the ETC Discord (edit: link removed for just-Reddit-things reasons, you'll have no trouble finding it) and will be watching for opportunities to tell people there about our miners if they don't know, and watching for info about their developments on SHA3 miners.

Building an ASIC miner with FPGA chips or manufactured IC's available on the market

Hi again. I recently made a post on using Arduino to replace bitcoin miners and i realized how crazily stupid that decision would be seeming as a typical Arduino has a hash rate of around 50
Now I needed a new way to build an ASIC miner seeing as Arduinos are out of the question. The two possible methods I came up with/discovered was by using multiple FPGA chips to do the exact calculations needed.
The other is by using pre-manufactured IC's from older GPU's, buying them in bulk and building many GPU's that are built around those IC's
I have three questions:

A field-programmable gate array (FPGA) is an integrated circuit designed to be configured by the customer or designer after manufacturing—hence "field-programmable". The FPGA configuration is generally specified using a hardware description language (HDL), similar to that used for an application-specific integrated circuit (ASIC) (circuit diagrams were previously used to specify the ... FPGA’s Edge. Even though the FGPA solution is extremely expensive relative to its GPU equivalent, FPGAs are widely available commercially. If the bitcoin exchange rate were to spike further, FPGA mining may be about the only option for being able to add any significant amount of mining capacity. Field programmable gate array (FPGA) is an integrated circuit designed to be configured by the customer or designer after manufacturing—hence "field-programmable".FPGAs are integrated circuits that can be tailored to suit a particular task like mining bitcoins, after their manufacturing thus creating ASIC. During the last years, the bitcoin mining ecosystem has been experiencing important changes. At the beginning, it was possible to mine bitcoin with a CPU processor, but later, it was possible to do it with GPUs. After it, GPU mining was replaced by FPGA and ASIC miners. What Is FPGA? FPGA stands for Field-Programmable Gate Array. A miner that makes use of a compatible FPGA Board. The miner works either in a mining pool or solo.. This is the first open source FPGA Bitcoin miner. It was released on May 20, 2011.
