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/

Making an Omnibot CNC plotter

First time I have seen one with 3 wheels instead of 4 and a write-up that involves the math behind it. Omni wheels have come down alot on price too…I saw some for $10 each. https://www.instructables.com/id/Omni-Wheel-CNC-Plotter-V2/

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.

Make a laser chaser bot for your dogs

I have thought about doing this myself. Pretty simple build to do but looks like the laser is not too random in its movement. Thought you can change the code to be more random. https://www.instructables.com/id/Arduino-Controlled-Laser-Dog-Chaser-Toy/

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

I want one of these sorting machines

Its fun to watch the video. Basically a light from the bottom lights up the parts for a camera to take a pic of and figure out what is what in shapes, then it picks them up and puts each … Continue reading
