Title: FPGA miner
Post by: tigerfree on May 05, 2013, 06:19:43 AM
Hi,

is there any open source FPGA miner except Lancelot ,Icarus i can get the FPGA Very cheap 50$ for 1 FPGA .


these  FPGA miner used in Lancelot ,Icarus and give 200 mh/s.

thanks

Look into software subforum: ../../Mining software (miners).

i want Hardware open source Pcb 2~4 layer if i got that mean i can get 600 mh/s for 100$

not trying to be a dick but this is not going to happen...if there was something I think a lot more people would be going this route rather than the ASIC USB key for 1.99BTC

@goxed i have these chips XC6SLX150-3FGG484C .


@dtmcnamara really i hated ASIC USB because i thought ASIC will be cheap .

For 600 Mh/s for 100 U$D you will have to wait fpga miner with kinkex or virtex 7.
Spartan 6 is in it`s limits.

If anyone want to start sell used fpga miners, I will buy cheap to recover fpga unit.

Tiger,

        I'm sure that once difficulty has increased enough for a FPGA-based mining device to cost more in electricity than it produces in Bitcoins, people will put these devices on eBay and you can snap them up cheaply.

most sell them in high price compared to the difficulty , i can get the FPGA Chip very cheap that why i me asking for open source FPGA .

I have a couple Cairnsmore1s with corrosion damage on the boards, but I'm pretty sure the FPGAs are good.  Any interest in recovering them?

How many LX150s can you get at the $50 price?  Can you get 600 pieces or more?

no really it will going to waste time but if it need FPGAs i can get you some.

i think my supplier can get it but i have to ask him first .

Ask him for pricing on 5000 Virtex-7s while you are at it.

will do .

Did you ever try replacing the fuse blocks on those boards?


Yup, I did that.  On the one board the heartbeat LED just glows weakly but does not blink.  When I connected the other board it tripped the power supply's short detection, and when the power supply came back on in a few seconds something went :BANG: on the board, and I see C55 now has a hole in its side that didn't used to be there.  I didn't plug that one in again.
