Nice little CNC plotter

I like this build. I was doing something similar with CDROM drives, but this is easier and uses servos over steppers. https://www.instructables.com/id/Tracey-Drawing-Machine/

A radio controlled wheelbarrow

The author did it to “race” the wheelbarrow. Me…interesting build and would be nice for a more practical use, like as a wheelbarrow that is motorized.

Cool suction bot

Nice build for a suction based robot. Uses a controller called OpenCR (new one for me). Which looks neat, but…costs 180 dollars… So if you are thinking about this build, a RPi and an arduino combo maybe a better approach. … Continue reading
