Fresh hacks every day
Gaming has infiltrated everything around us. It seems that any time a control interface is needed, the first thought to many current hacker’s minds are the familiar controls from the video games we grew up with. In this example, [eljaywasi] needed a way to control the wavelength of light coming out of a laser. We don’t know exactly how he’s … Read the rest
[Eiki] found himself in need of a project for his “simple machines” class. Another project had brought him in contact with some relatively cheap MEMS accelerometers and gyroscopes. He had the idea to create a simple tilt sensor based circuit that would light whatever LED was at the bottom.
He’s using an Analog Devices ADXL202E accelerometer chip to sense … Read the rest
[Bertho] sent in a great tutorial on terminating transmission lines. If you’ve ever tried to send a high frequency signal a long way down a wire, you know the problems that can crop up due to electronic strangeness. Luckily [Bertho]‘s tutorial explains just about everything, from where and when to terminate a cable and why signals get screwed up … Read the rest
This project from a few years back is an interesting take on a metal detector. Instead of building a detection circuit, [Bruno Gavand] replaced the external clock crystal with an inductor. Here you can see the inductor coil next to the PIC 12F683. You can see two components jumping from one breadboard to the other. These are smoothing capacitors … Read the rest

So at first glance we were thinking there wasn’t much special about this clock. It’s based on an Arduino and displays the time using a character LCD screen. But then we realized that there’s no battery-backed RTC and no buttons. How the heck do you set the time on this thing? [Mossblaser] is using a light programmer to set … Read the rest
This is a robot that any Transformers enthusiast will love. Sure, the car looks just a bit boxy, but you’ll forget all about that when you see it unfold into a bipedal robot (translated). [Zak Sawa] is responsible for the creation. He pull off the build using 22 servo motors which let the car transform, and provide the … Read the rest
This radio controlled car controller replacement is a great project to try some new things with that fancy hardware you’ve got sitting around. The hack comes in two parts, the receiver and the transmitter. They’re communicating via Bluetooth so if you only want to build one side of the hardware you should be able to make most Bluetooth devices work … Read the rest
