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/

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/

Using planetary gears for more torque

The video does a good job explaining why and how you go about doing this. Its an intersting one to watch and helps explain why you would want to do this. https://www.hackster.io/news/this-split-ring-compound-planetary-gear-system-can-achieve-super-high-reductions-4f2c4e103a22

Interesting cheap multi switch automation setup

OK I definately will not make this build. Neat looking where the author uses a stepper to “move” a servo across a row of light switches to turn them on and off. https://www.instructables.com/Cheapest-Plug-Play-Room-Automation-Setup/

Neat M&M sorter

Neat build, the author 3D printed the hardware and uses an arduino as the brains to sort M&M’s. https://www.instructables.com/Arduino-MM-Color-Sorter/

One fancy 3D printed camera motion control rig

Wow this is one complex build. Not so sure I would make this one, even if my printer could print the larger parts. Nice to watch the build thought.

Tennis ball launcher build

The author designed and 3D printed a tennis ball launcher for his dog to keep the dog entertained. Nice build, but two things, it currently only does one ball at a time (so needs loading cage). and second would be … Continue reading

Nice Chess playing robot

But way more work than I would do to make one. Nice build overall thought. https://www.instructables.com/id/How-to-Built-a-Chess-Robot-With-Arduino-Mega/
