Sometimes we forget to put our trash cans out until the garbage truck is already outside. What we need is Max Maker’s Trash Train running on a schedule. Max built this automated railway for his cans when he had to start storing them on the other side of his house. Engineering and fabricating it was more complicated than it looks.
This arcade game is as small as they come. It runs on an Arduino-compatible 32-bit processor and has a tiny full-color OLED screen, a D-Pad, two pushbuttons, plus a built-in speaker. It comes pre-loaded with three homebrew games, and can be expanded with more games via a MicroSD card. Takes about 10 minutes to assemble.
Xyla Foxlin likes to build all kinds of things but has a special affinity for canoes and paddles. Using an existing canoe as a mold, she created a translucent fiberglass vessel that she wired up with strips of RGB LED lighting, making it the most vibrant and colorful boat on the water.
Dimitar Tilev shows off a truly awesome R/C car build. This scale replica of a vintage Oldsmobile Dynamic 88 wagon packs an Arduino-controlled active suspension which can raise and lower, along with a rear-wheel drivetrain that makes it especially adept at drifting. We love the engine noises and light-up tailpipes.
Telegraphs were once the fastest way to send messages over a distance. While they’re long since obsolete, DIYprojects decided to build a modern take on the paper strip telegraph, using an Arduino Mini, a motor, wood, and a pen to write down text messages. Build guide here.
We’ve seen industrial machines that can bend wires into shapes, but thanks to 3D printing and low-cost controllers like Arduino, you can make your own desktop machine now. How to Mechatronics shows us exactly how. Grab the full instructions, models, code, and schematics here.
