This futuristic-looking dustbin features a motion-activated iris mechanism

Have you ever met a person with an exceptionally neat, tidy, and well-decorated office? Everything is intentional, from the furniture finishes to the potted plants. Even the trash can needs to fit the aesthetic. That’s why Akashdeep Singh of The Wrench YouTube channel designed this fancy 3D-printed dustbin for his new workshop that features a very cool motion-activated iris mechanism. 

This is a small dustbin perfect for putting on a desk. Not only does it look awesome with cassette futurist aesthetics, but it is also functional. Wave your hand over the top and the camera aperture-like iris mechanism will open up for a moment, so you can toss your garbage in. A few seconds later, it will close, keeping smells contained and unsightly refuse out of view. Finally, the body of the dustbin attaches to the base with magnets, so getting access to empty the bin is quick and easy.

That iris magic happens thanks to a pretty simple gear ring mechanism actuated by a small hobby servo motor. That servo motor operates under the control of an Arduino Nano board, which tells the servo to spin when it sees motion through an ultrasonic sensor. To avoid external wires, power comes from an 18650 lithium battery with a voltage booster to get clean 5V to the Arduino and servo motor. A custom PCB designed by Singh ties those components together in a compact package.

All of the mechanical parts to build this dustbin are 3D-printable. If you want to do that yourself, you can find the necessary 3D files and Arduino sketch over on Cults3D.
