If you run a small business where transactions are made, handling out coins is a necessary part of the job. While a cash register does the trick, perhaps you could try out the SmartCash device—a cylindrical electromechanical system running on an Arduino Mega—to help you count coins and make change. Aside from sorting coins, there’s the added […]
We all need to wear clothes, but where do they come from? If you answered “the mall,” then perhaps it’s time to play a couple rounds on the “Meme Weaver.” As seen here, this project by the husband and wife team of David Heisserer and Danielle Everine prompts users to adjust levers correctly in order to […]
While there are many ways to move an airplane on the ground, Anthony DiPilato decided to create a “tug” of his own. The treaded device looks like a tiny tank, and when it slides under the aircraft’s front wheel it locks in place, allowing a 5,200-pound plane to be pulled around courtesy of the RC system’s […]
Arduino All Over With the arrival of Spring, just prior to the ending of the academic year in Spain, teachers and education initiatives have been celebrating STEAM events all over the country. I personally attended RoboCampeones in Fuenlabrada, a small city outside Madrid, but there were a lot more: Robolot, FanTec, Cantabrobot, Granabot, ROByCAD, and even […]
Would you like to create a robot that slithers from place to place like a snake? Well now you can, thanks to this bio-inspired design from Will Donaldson. Donaldson’s project uses 10 metal gear servos to allow his robotic snake to curl its body back and forth, sliding along on small wheels that replace a real serpent’s […]
If you’d like to monitor your driving habits, or perhaps keep them handy in the event of an accident, a “black box,” or more properly a “telematics” device is just what you’re looking for. Monitoring driving habits can be interesting, but what if you’d like to make a telematics box yourself, giving you total control […]
If you’re a high school student and would appreciate a vending machine in class, what’s to be done? Most of the time the answer is “not much,” but Tustin High T-Tech students were able to get one—by building it themselves! In fact, this excellent device functioned both as a class project and as a fundraiser […]
We recently visited NextFlex, the flexible electronics manufacturing institute in Silicon Valley, where they developed a flexible prototype based on the Arduino Mini. Their mission is to make flexible electronics mainstream, opening up all kinds of new applications. How did you make the flexible Arduino prototype? Some of the equipment we use is familiar. For example, automated screen printers and […]
If you have an unused Teddy Ruxpin lying around, you’re in luck. This hack from “Jayden17” turns the iconic ’80s toy from a fancy tape player into your own talking bear assistant! The build started out with obtaining one of these vintage bears and fixing up the internals, as well as equipping it with a new speaker. […]
After being inspired by an Old Spice commercial where actor Terry Crews plays music with his muscles and EMG sensors, hacker Julio David Barriga decided to do the same thing using an Arduino. While Crews’ setup involves an entire one-man band, Barriga’s system is greatly simplified, detecting the amplitude of the electrical signals emanating from […]
