He decided to see what it takes to recreate one of his favorite Arcade games (Bomb Jack) using only VHDL, the games schematic, the Open Source T80 Soft Processor, and technical information available on…

  • $10 VGA camera on the Papilio One? How about a free PCB to try it yourself?

    Several months ago we designed a Wing for the OV7670 camera that can be found on Ebay for around $10. To our delight Voelker contributed VHDL code to interface with the very same camera! To show our appreciation for this contribution we are giving away all the Wing PCB’s that we have sitting on our…
