I like building things, documenting them not so much. :-)
This is a Kickstarter project to encourage me to document the feeders I built and to release the documentation open source.
The feeders have some CNCed parts (could be laser cut), and some 3D printed parts (which could be CNCed). They use inexpensive gear motors and simple electronics to advance the parts one "notch" of 4mm.
The design embraces the KISS principal, and the use of inexpensive and readily available parts. I haven't done a detailed analysis on the costs (did I mention I prefer building to documenting?) but the cost per feeder (parts and materials) is about $30.
If there is enough community interest in this project to fund it, I will provide detailed drawings, assembly instructions, hints, tips, source code for CAD, bill of materials, variations on design, pcb gerbers, etc. Enough documentation so that they are easily to duplicate.
