Cool looking clock build

A digital clock that is mostly mechanical. They author is using an ESP to control it too. https://www.hackster.io/news/charlie-sheen-helps-design-a-seven-segment-mechanical-clock-ef53a129e114

PVC made CNC

Its a plotter/laser engraver build. Overall pretty clever build. Reminds me of the little CNC’s made 10 years ago with iron pipe. https://www.instructables.com/P-CNC-Laser-Engraver-and-Pen-Plotter/

Make the lady gaga sound active mask

Nice build overall, a bit pricey since it uses several colored, addressable, LED displays. Also could be a bit of weight to wear on ones face. Uses an ATiny for a controller. https://www.instructables.com/Lady-Gaga-Cosplay-Making-the-LED-Matrix-Mask-From-/

An arduino powered haunted pumpkin

The author made this build pretty simple to do, the arduino controls some LEDS and a speaker, and gets input from what I think is an IR distance sensor, but I bet this could be adapted to Ultrasound. Once someone … Continue reading

POT to PWM controller

Using an ATiny no less, bascially you turn the POT, and a PWM comes out to control the motor speed. Good for DC based motors. It also has a nice small footprint. https://www.instructables.com/Poti-PWM-Control/

Another interesting Drawbot

This one does not use gravity, its an interesting build with most of the parts are 3D printed out. Not so sure if I would put this one on the list (take too long to print everything out). I do … Continue reading

Different take on a CNC plotter

Build to look like an odd robot. The good news is the base pieces are PVC pipe and are cheap and easy to come by. Downside, most of the other material used is not. Also wonder if there is a … Continue reading

Neat hot wire CNC

Its a neat build that looks like an Ender3 base. I like how the author has “clamps” built into the base to hold the foam board in. https://www.instructables.com/Spatial-Hot-Wire-Cutting-for-Complex-Surfaces/

A pretty serious nerf ball turret

The motors the author uses this are ones you find in higher end RC cars. Its a clever build and seems to shoot an move pretty fast. https://www.instructables.com/Arduino-NERF-Ball-Wireless-FPV-Sentry-Turret/

3D printed mini cooler

basically the author takes a 3D printed jet engine like design and puts it on a swamp cooler. Seems a bit of an expensive build overall. https://www.instructables.com/3D-Printed-Mini-Air-Kooler-the-OverEngineered-Edit/
