Honestly, for the price of an FPGA miner you could get a good ASIC miner, which gets many more MHashes/s.
Look at this:

About 100 M/hashes on my de2-115 FPGA, though I am planning on setting up my Radeon 7800 soon. Wonder how much that will get me

I am debating whether it makes more sense to mine for LTC or BTC, considering that my FPGA can do a max of 104 or so MH/s.

Hello!
I have an FPGA I used in a high school project, and I need help setting the FPGA up to be a bitcoin Miner! Until I can reach the other side of the forum, I guess I am waiting here...

Hello all fellow bitcoin miners,
I have a de2-115 that I used for a high school project that I would like to convert to a bitcoin miner. I used the Open-Source-FPGA-Bitcoin-Miner code which was optimized for this exact FGPA (luck I guess) and I have run into a few problems.

1) Whenever I run mine.bat, it comes up with the error -
> ERROR: Unable to getwork. Reaon: key "result" not known in dictionary
This could be because of the old version of Quartus I am using (10.0) - If anybody could confirm or deny if that is the issue, I would be greatful!
2) The core seems to get very hot even with the acrylic casing off. Has anybody implemented a cooling system for this FPGA
3) I have heard that there is a way to get this program to run at 100+ MHash/s. Though I wouldn't dream of implementing this until I figure out a cooling mechanism for the FPGA, does anybody know where the sof file for that is?

Any help would be much appreciated.
Thank you very much!
