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 […]
While building a walking robot especially with less than six legs can be quite a challenge, maker “Skill Mill NYC” decided to construct a quadruped robot named DoggoBot using cardboard for its body. Four micro high torque servos power the legs, which are able to move the robot around with the help of unpowered knee joints. […]
In the video below, Brazilian maker Eduardo Zola shows us that you don’t necessarily need radio waves to pass messages between Arduino boards; instead, he’s using ultrasonics. Zola’s setup features TX and RX transducers desoldered from an HC-SR04 module along with a pair of Unos to transmit text short distances. An LM386 amplifier and LM393 comparator are […]
If you’d like to check out your pool or a lake without getting wet, this underwater ROV looks like a great solution. The DIY device features a sturdy PVC frame with six thrusters that allow it to move through water like a drone through the air (complete with depth and heading hold), and uses the same […]
