Fresh hacks every day
What a strange message to read on the digital dashboard display of your car. This is proof that [Kristoffer Smith] was able to control the ODB-II bus on his Eagle Grand Cherokee. He's not just doing this for the heck of it. It stems from his goal of adding an Android tablet on the dashboard which has been a popular hack as of late. This left [Kristoffer] with steering wheel controls that did … [Read more...]
Here's an LED and Button shield for the Stellaris Launchpad (translated) which you can fabricate at home. It gives you access to a 5x5 matrix of LEDs, and adds four more buttons. In order to cut down on the number of I/O pins required to operate the lights [Cosimo] is using the concept of Charlieplexing. This lets him get away with just six driver pins and four button pins. It's not just the … [Read more...]
[Chris] has been going about his business, letting his interest guide him as it will. But always in the back of his mind is his Androcade project, and he's spent the last year making improvements. It's an arcade controller for playing games on an Android tablet. It connects to the device via Bluetooth, and includes a built-in stand. His original version was featured here last year. It was made … [Read more...]
[Aaron's] arcade controller really makes us want to put in a button order. There aren't any secrets hidden in his design or fabrication, but he did a remarkably clean job of putting it together. The housing is a writing box he bought at the hardware store (but he also shows off an emtpy Xbox 360 case hosting the same control layout). It has a hinged cover which is perfect for getting at the … [Read more...]
We covered SparkFun's new RGB button pad controller a few weeks ago. This is a full-color clone of the monome interface; a 4x4 grid of buttons with tri-color LEDs underneath. Each LED has 24bits of color control, for more than 16million color combinations. Up to 10 panels can be chained together to create huge button grids, like SparkFun's Tetris table. We previously used a smaller version in our … [Read more...]
Electronics parts can be a pain to choose. It's often hard to tell from manufacturers' datasheets if a part will fit your design. We auditioned six different tactile switches to find a cheap button to use in upcoming projects. A tactile switch, also called a momentary button or push-to-make switch, is commonly used for input and microcontroller resets. This type of button creates a temporary … [Read more...]
