This posting may seem a little late, but getting this info together is actually a bit of work. But now someone has actually expressed interest in making one of these so I feel I have an obligation to post the design files.

Now I don't have much experience posting a Kicad design, so please bear with me. If there are files or info that are missing, just tell me what they are and I'll try to post them. I apologize for any inconvenience. It is my intent to reveal the design, not hide it. I just need to know what's needed.

Please see the files section for the actual files. You should create a Kicad project directory to hold them. I'm sure you'll have to mess with the paths and possibly the project file name. Next I'll try to get a parts list together.
