If you want to scare some kids as they approach your house to get some candy on Halloween have a look at this project by GreatScott. He uses an Arduino which has an ultrasonic sensor connected to it. The sensor detects when someone gets into the scare zone. To scare the curious kid some LEDs light up the pumpkin and a buzzer sound. This idea could be adapted many
So if making a robot that can be remotely controlled wasn’t a tough enough challenge the guys over at Ufactory decided to make one that can roll around on a ball. Great looking design and it sounds like they are going to do a Kickstarter for it and release it as open source hardware to the community. I can’t wait to see a larger version that can be ridden
 RC cars are fun but why let the fun end at driving it around with the supplied remote? Shazin Sadakath got a car and tore it apart to see what made it tick. He took an Arduino and was able to hack it into the car circuit to be able to control all of the car functions with the digital IO Arduino pins. After learning how to interface
One common theme amongst 3D printers is that most of them print layer by layer. The printing is normally started on a flat build platform and grows from there. This is limiting though since with this limitation you would not be able to do things such as build a design around a curved platform or on an irregular surface. This 6 Axis prototype 3D printer changed that by giving
If you have ever wondered how one of those RGB LED light bulbs work have a look at the article that chr has put together. By monitoring the IR LED of the remote he was able to snif the IR remote codes for the functions. Once he knew the IR codes he used an Arduino to run through all of the byte sequences but unfortunately there were no easter
Julian Ilett demonstrates his Arduino Solar Charge Controller. He has mounted all of his Arduino modules to a piece of wood to keep everything nice and neat. “High efficiency values (96% – 97%) are achievable when the buck converter is stepping down from 18v to 12v. With a 72-cell panel and the converter stepping 35v down to 12v, the efficiency drops to around 88%.”
If you want to fly an RC plane but don’t think getting used to flying with a standard RC remote this glove control system might be a build that could help you fly. It has some interesting features that help to make flying the plane more intuitive such as simply tilting your hand from side to side to bank the plane instead of moving a joystick. “The Spatial Hand
