ksubikillah: will you make a tutorial on how to build in the future?
DarkTrunksGeorgeSim: Hah, cool. The pirates of the 21st century.
Tycho343: Yes, FPGAs are good for such applications (not ANY general purpose
calculations, but mostly integer/binary, related to cryptography). You
should note that designing for FPGA may be much more difficult that
programming for GPUs, so it's useful when you need lower power consumption
or higher scalability.
Mountshilol: Are us selling off any of rigs now?
Tycho343: @dutchFurries this current setup is connected using USB cable to each of
the boards. Price and availability depends on the quantity required.
Tycho343: @nlucctw2 current and expected prices are in range of $400 to $580 for one
dual-chip board. More efficient and cheap designs may appear later.
Keith B: how can i make one ?
dare21magine: whats the board your using ? please ?
Tycho343: Sorry, but you can't if you have to ask. You need a Spartan6 150 version
chip with appropriate power supply, but it's BGA and very difficult to
solder at home, almost impossible.
teknic111: I am very new to FPGA boards. Can these be used for other GPU intensive
applications, such as Pyrit?
Tycho343: Those are ready to use boards. You just plug them in and launch the
Tycho343: JTAG connection is available.
ALTElektrik: а музло то наш играет.... по нему и спалился...
Mountshilol: I admit I am a not a hardware technical guy but I want to create a mining
rig or by one that using the new fpgas not the old gpus how did you get
yours up and running?
Tycho343: Yes, but you are talking about BFL which I'm not interested in :) Otherwise
Benjamin Perry: where did you buy this cards ?
Andrew Boynton: can you explain?
Andrew Boynton: how do you program the boards to mine though?
Tycho343: Thanks. Those boards are based on Spartan6 FPGA.
sinnersaintx1: what model fpga are you using?
Mountshilol: question I know someone in the bitcoin economy is making money and we all
know its not the miners bc minining be blamed for all sorts of hackings and
pump and dump but then why are there some many exhange websites and whats
funny they build programs to create better exchanges some with fees so
doesn't anyone build a program to fix the hashing because this i
cryptography 21 million what about being unlimitless and allowing the users
to create there own business or pump and dump
CRAKIZGOOD: i keep seeing you using the words "reusable" when your talking about FPGA
what do you mean exactly ?
Tycho343: I sold all my GPUs recently, but why would I sell FPGAs ?
Tycho343: No, it won't become mainstream BECAUSE of ASICs. Mining is just a service
task like transaction processing by Visa/MasterCard. You don't need to mine
anything, just use bitcoins for payments. It's not a make-money-scheme,
it's a currency. You aren't mining USD, right ? :)
sashadevet: круто. $ в день имеешь? и причём тут сиетема)
Tycho343: Added song info to the description.
Thiago Borges: so.. specs please?
MinecraftMan7778: first. i know this is old. second. i bet you money i could get it for less
than 1k. usd.
thegreathead: where would someone get this equipment and the software to run it?
евгений бровкин: за сколько сделаешь подобную Штуковину?
Niko Punin: I'm selling ztex 1.15x boards 27BTC a piece
CRAKIZGOOD: i have a question ive seen some people have huge GPU bitcoin rigs
everywhere which just uses ALOT of power but these FPGA can do the same
amount of work for about the same price/performance without using alot of
CRAKIZGOOD: with ASIC approaching it seems that bitcoin will become mainstream because
of how cheap they will be will difficulty the difficulty increase ? btw how
many bitcoins do u get per day ?
Andrew Boynton: I will pay you if you can help me get these and program them. how many
hashes do you get?
Portugal Designlab: Helllo Tycho how can i build one just like yours can you tell me. please
send me a message
Tycho343: I only said it twice :) It means that some FPGA mining products can be used
for other purposes without unsoldering the chip. Icarus and Lancelot boards
have LOTS of GPIO pins routed + lots of chip interconnection channels, so
they can be used for many other FPGA projects or sold to someone.
Voodoo Hack: where can we buy parts :)
Tycho343: Same as everyone else - Xilinx Spartan6
Tycho343: You can google for "JTAG". It's a special kind of interface that is using
for diagnostics and bitstream flashing.
Mountshilol: So basically you don't have anything to sell?
2jpu524: Do you write your own HDL code? ..You likely will be able to boost your
maximum frequency by pipelining. I've seen many cases where a design stuck
at 52 MHz would be able to run at 528MHz (8 tap FIR filter, not pipelined
vs 8 stage pipelined). It also pays to understand the internal architecture
of your FPGA (like the DSP48 multiply accumulate blocks found in the Xilinx
orangedac: What's the song in the background?
Craig McLeod: May I ask which is the best of model to use: there appear to be a number of
them: I looked up the spartan 6 series and there are pages and pages of
them with slightly varying specs. I would like to setup 1000 of them.
Tycho343: I can recommend "Lancelot" boards. They are not available to general public
yet, but it's the most reusable FPGA solution ATM.
Vitaliy Kiktev: Добрый день.У меня есть пара вопросов. Свяжитесь со мной по скайпу
Tycho343: @blackbeard68 each board is hashing at 370 MH/s, 20W, nice and silent. I'll
never build a GPU rig anymore :)
Tycho343: Yes, FPGAs use around 7-8 times less power than GPUs at same hashrate.
nlucctw2: how much do these cost?
