For an easy plotter design that you can build with only simple hand tools, be sure to check out this tiny project from Mr Innovative. The machine features a pair of stepper and lead screw assemblies to maneuver a pen in an X/Y plane, along with a clever string and servo setup to handle retraction. […]
After deploying a remote weather station over two years ago, self-proclaimed ugly pirate Tecwyn Twmffat needed a better wireless communication solution. Originally, his installation used a GPRS modem to transmit data over the cellular network, and while this normally worked quite well, the module would get booted off the network during updates. Additionally, its solar […]
Bryan Kevan wanted to build his own bicycle, but wasn’t satisfied with purchasing a frame—or even ready-made tubing. He instead chose to create the frame from raw strands of carbon fiber. The overall bike build is shown here, which necessitated him designing a variety of jigs, including a CNC wrapping machine. His device uses an […]
Seating charts at weddings and other formal events are usually handled by small place cards, but Gabrielle Martinfortier had other plans. For her big day, she along with help from her now-husband and friends constructed a seating arrangement on a 3’ x 4’ wood canvas, equipped with a 7” TFT display and an RFID reader. […]
Normally, boiling an egg involves heating water in a saucepan, then dropping an egg inside to be properly heated. James Bruton, however, now has a bit of help in the form of his breakfast-making robot. The device uses two servos, along with a motor/encoder/screw assembly to rotate and lower the egg into place. It then […]
After letting his Arduino languish in a drawer for some time, Brandon Switzer decided to take it out and start experimenting. While he could have started off small, Switzer chose to instead create his own player piano system, completing it at a cost of around $650. While the details of the project aren’t explicitly spelled […]
Hunt the Wumpus is a text-based survival/horror game developed in 1973. As such, it’s perhaps due for an update, and Benjamin C. Faure was able to do so using an Arduino Mega to run a graphical version on an 8×8 MAX7219 LED display. The game consists of moving your character through the 64-LED randomly generated […]
Glue sticks are great for attaching electronics and other bits to projects, but as Jon Bumstead shows in his latest work, they can also make pretty cool light diffusers. His project takes the form of a wooden box with plexiglass panels, allowing observers to see 64 vertical illuminated glue sticks inside. Hidden within the cube […]
If you need a motorized turntable for filming or simply displaying your latest project, here’s an easy 3D-printable option from Ali of Potent Printables. The design takes two forms—one using a full-sized hobby servo, and a smaller version that employs a micro servo for motion, both of which are set up for continuous rotation. Electronics […]
If you’ve ever been to an escape room, you’ve undoubtedly had to deal with a wide variety of puzzles that you have to solve in order to get out of the “prison” that you’ve willingly thrown yourself into. Beyond the puzzle that you’re trying to decode, the mechanisms used can be extremely clever, and coming […]
