Nice CNC Etch-a-Sketch build
A bit older article, but its a nice build where the author can draw on an etch-a-sketch.

Use RemoteXY to control a robot arduino
Basically its a wizard for creating an “app” to control an arduino via wireless. Seems pretty neat.
Cool robot build
Uses an arduino to control the servo’s for the arms. All parts are cut from plex board. https://www.instructables.com/Bidex-Robot-Dual-Arm/

Nice Robot gripper
This one uses belts to pull and grip objects.
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/
Cool robot that can swim, skate, and crawl
Came out in 2018, but still a neat robot to watch in action.
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/
