I know this has been asked many times... But I would Like My own answers... Can Anybody Tell How To Create My Own Low-Cost fpga miner.
Since It's "Cheaper" than gpu's and ASICS - It seems to be my best bet. I "REALLY" need to start earning Some Bitcoin of my own... Thanks!
PS: Smart-Mouths Need Not Reply!
I think right now is an odd time to get into FPGA use. An FPGA costs around $0.50-2 per MH/s at [almost] negligible wattage. An ASIC costs around $0.10-$1 per MH/s at slightly higher wattage but far greater power density and [presumably] ease of setup.
That said, you can get a ~400 MH/s FPGA right now for around ~$400, while the 40,000 MH ASIC could take 2-4 months to receive and cost ~$3000
an FPGA can be re-programmed though, while an ASIC device has few other uses besides bitcoin.
This, I myself am working on an FPGA using the newer Xilinx Atrix-7s
Basically what you need to do is first figure out what chip you want to use, be it the atrix-7, spartan-6, etc.
Then you have to design a pcb for it to get power to to it, get the data from comp to the chip, things like that.
Then you have to put the chip on the pcb, and make sure it works and gets correct amount of power.
Then you have to do the software part, I myself am going to use the Open Source FPGA miner, although you may opt to make your own miner software, either way it will have to be optimized for your setup.
