The program allows the nozzle to move in the interval (60 degrees; 120 degrees). Initially the servo is at 90degrees, so it can move 30 degrees either clockwise or counter-clockwise, but in vertical plane. It reads the state of the buttons. If one...
I found a mushroom lamp design on Thingiverse, which uses a PIC az it's uC. I have tons of Attiny85 lying around my desk, so I modified it. Here are my results.

The DMM body comes with a segmented LCD that's connected by a zebra strip. The battery compartment connects to the PCB via spring contacts. The buttons are carbon covered rubber stamps, which are shorting the exposed pads on the PCB. Example Project:...
Zero is being built on my K-9's chassis and will use all of his electronics. I'll be controlling him with the Shadow system built mainly for Astromechs. It's been adapted for K-9 and it should be easy to swap it over for Zero as well. The main body of...
