converting an old plotter into a camera slide

The author took and old plotter and make a motorized camera slide out of it. Nice build, only issue I can see is its a “short” slide. https://hackaday.com/2022/04/07/turning-old-plotter-parts-into-a-smooth-camera-slider/

A drawbot that can use a multi color pen

Interesting build for a drawbot, it uses a multicolored pen to switch colors, instead of changing the “pen” for each color. https://www.instructables.com/Multicolor-DrawBot/

Interesting build for a automated pet feeder

Nice build overall, just it would need a top to keep the pet from getting into the dispenser. https://www.instructables.com/Simple-and-Easy-Automatic-Pet-Feeder-With-Arduino/

Nice Halloween bat build

This just shows why home loom robots don’t exist yet

This is an OMG this is a complicated build and very picky. Shows why folks don’t have CNC like looms for clothing yet (well on the cheap hobby scale). https://hackaday.com/2022/06/07/3d-printed-power-loom-shows-how-complex-weaving-really-is/

Well this is one way to make money with a 3d printer

I first heard about someone in Texas doing this, but apparently someone in NY (Utica) did it too and walked away with 21K in giftcards (500 dollars per gun). Most of the prints where just receivers or parts, so surpised … Continue reading

Nice laser engraver build

Cool 3 color CNC wall plotter

Reminds me of the Maslow CNC in its build. Most of the parts are 3D printed and it has an internal gear to switch markers. I like how the author uses vasoline for “grease”. Parts here https://www.thingiverse.com/thing:4192091

3D print a frame for Pingpong ball disffusers

Basically you use the ping pongs as an LED diffuser. Neat idea.
