Thank you very much for posting your design! I was wondering if you had a partlist including the large capacitor at the input. I am trying to do the same thing but will be using NI’s RIO FPGA system as the controller to provide versatility thus I am just trying to replicate the driver portion. I think I have most of the components identified but want to make sure. In addition I am a ME with a slight background in circuitry but wasn’t sure of the reasoning for the C38 through C51 capacitors in parrallel vs using just one and how do you use the multiple signals to calculate the current?

very interesting, is your board assembled and running? is there more to come?

Are you still active on this work? I have just found your blog via a comment on linked.in. I do something similar in my (rare) leisure time: http://letsmakerobots.com/blog/15537. Do you see any common ground?

Yeah, I’m very interested in the anwser to same question. Either RGB or even VGA output. Not only would it save a couple Playchoice 10′s PPUs but also provide proper palette and a solution for PAL-version which can’t have its PPU swapped just like that.

Some time has passed, but no report on the board : did you ever get it assembled ?

I’m tempted to try a board with a Spartan 6, SDRAM, and PCIe (a slimmed-down SP605) and would love to hear more about how your test board worked out.

Please excuse me if what I am asking is out of the realm of possibility ( or practicality). I am just recently learning of fpga’s and was curious if one could be programmed as a replacement ppu on original NES hardware? The reason would be to get an RGB signal out of the NES rather than composite. Many collectors try to get the most out of there hardware and to get rgb video out of an NES requires replacing the ppu with that from VS System arcade hardware. Besides the cost issue, the hardware is becoming extinct. Maybe if an fpga could be used, people wouldnt destroy good hardware for a single chip.

I would like to prototype up something similar.

What a website. Tons of info !…. I’m designing my very own motor controller with an AVR and Allegro chip. Have you got any source code showing how to do odometry ? Would love to see it if you have something.
