A DIY The Wrench maker has built a smart desk dustbin with an automatic iris-style lid, adding both functionality and a unique touch to a workspace. After some adjustments, the final design was printed successfully using a 3D printer using a design made in Fusion 360. Different filament colors were used to make the dustbin visually appealing.
The smart feature of the dustbin is powered by an ultrasonic sensor and a small servo motor, controlled by an Arduino Nano microcontroller. To keep everything organized, the maker created a custom PCB, for its compact look. They added a rechargeable battery and a charging module too, so you don’t have to worry about plugging it in all the time. When a hand approaches the bin, the sensor detects the movement, and the lid opens automatically. The iris-style lid open and closed smoothly, making it an easy way to keep your desk clean.
If you want to build one yourself, the maker has shared all the design files, code, and PCB files in the description. It's a fun project that's perfect for anyone who loves a bit of tech on their desk. This build combines simple electronics, 3D printing, and creativity, showing how accessible technology projects can enhance everyday items.
