Here are the schematics for our main board. Pretty simple design based of the Arduino Uno. All the pins are using the Uno's pin labelling in this schematic, but not the pin numbering, be aware of that. You can also use a CNCNano board to replace these electronics, but they'll have different pin mappings... but should be pretty easy to duplicate the board if you wanted to.
More details coming soon. There are no restrictions on using this (simple) design... it's now in the public domain.

Fantastic. The shipping costs to the Netherlands were too high for me to buy the 3D Chameleon. I had already started to reverse engineer the schematic myself: Arduino Nano equipped with display, switch and logic analyzer. This saves me a lot of work.
Thanks. I don't do a lot of hardware programming, but nice to know the info is available if I want to do so.
Thank You Bill for sharing this huge project of yours with all of us. Are You planing to release the firmware as public domain also? Without the code i´ll be quite a lot of work to get the 3DChameleon running. And - looking at the filename of Your schematic - named MK7 - I guess this will be the next generation firmware with all the sensors? Again, thank You for allowing us to participate in this project.
