Design of small CPLD passthrough
I have designed a small and simple passthrough using a CPLD (Complex Programmable Logic Device). Expected cost is $30 in parts. Lynx is going to build and test it in about 2 weeks since this is how long it takes to receive a custom PCB. The schematics and other files will be soon posted on this weblog for your amusement. Detailed How-To will be published after the board is made.
PassMe uses VHDL code based on DarkFader’s passthrough.
For now, here are rendered pictures of top and bottom sides of the PCB:

you should send this to a pcb manufacturer, and get them made in bulk, that is if we can get some bread!

need to manufacture it if it works

Hey, that looks really great. What are the dimensions?

Dimensions are 3.5 cm x 5.4 cm. Although, one could leave less space at the top.
You can see the outline of the DS cart on the PCB. One would have to file down the board to that outline.

Once this is tested, is there any chance someone could make up parts kits for those of us outside the States? Digi-Key’s export policy is rather unfriendly, so it works out pretty expensive to order the parts for even one…If someone was willing to get a few extra boards and sets of parts in it’d make things much easier.

Your site is a much needed addition to my life. THANK YOU!
