Cigarboxnation.com is a place for people to get plans and share their cigar box creations with other makers. I went there to get some new ideas for my cigar box amps, and I decided to join and share my experiences.
Pcbgcode.org has a good forum that can help you with PCB-GCODE issues. The program is used in conjunction with Eagle cad to produce files to create circuit boards and other great CNC things. I can’t really speak with authority about it all because I am still learning. As noted in my “Preparing for CNC delivery” page, I haven’t received my micRo CNC router yet, but I’m learning as much as I can in the waiting process.
I’m not a paid affiliate of any sites mentioned ever in my blogs. I only mention sites that I think can help my readers get more out of their hobby.
