Fresh hacks every day
Back in the 1980's there was a movie cliché that the person with the largest boombox on their shoulder was always the coolest. It's obvious to us that [Tim Gremalm] thinks that's silly. Why be uncomfortable carrying something like that on your shoulder when you can strap a much larger object to your back? He's working on a mammoth speaker enclosure which can be carried around, but he needed a set … [Read more...]
[Deekshith Allamaneni] built this controller which will automatically turn the lights in a room on and off. No big deal, right? You can already get a replacement light switch at the home store that will do this for you. But there is one big difference. The commercial solutions we've seen simply rely in a motion sensor and a timer. But [Deekshith] found a way to count the number of people that … [Read more...]
North Street Labs really brought their 'A' game to the build finals for the Red Bull Creation contest. Behold the Centrifury, their spinning hell of a game. You can't really make it out (because of the spinning) but the game consists of two bucket seats positioned opposite of each other on a merry-go-round type deck. Each player has a button in front of them which must be held down for the rig to … [Read more...]
[Michael H] tipped us off about this guide to using view camera lens parts with DSLR cameras and lenses. We weren't familiar with the term 'view camera' but we certainly recognize the accordion-like bellows that define that type of camera. The idea is that modern cameras with their fixed lenses miss out on some types of shots. Why not work out a way to get the best from both old and new? The … [Read more...]
The security flaws on this common hotel keycard lock are nothing short of face-palmingly stupid. Look closely at the picture above. This is a hotel room door swinging open. The device he holds in his hand is an Arduino connected to the OUTSIDE portion of the door lock. It takes approximately 200 milliseconds from the time an attacker plugs the device in, until the door can be opened. Yes, in less … [Read more...]
In this project [Ryan] shows how he added Bluetooth audio to the stock stereo of his Toyota Matrix. The work he did with his add-on hardware is quite good. And the installation was surprisingly easy. For example, the dashboard bezel which is hanging in the foreground of this picture simply pulls off without the need for any tools. Also, the CD changer input for the stereo is what he uses to patch … [Read more...]
[skywodd] just finished his own DCPU emulator (French, translation) based on [notch]'s upcoming game, 0x10c. The neat thing about [skywodd]'s build is his emulator uses the lowly ATMega328, the same microcontroller found in (some) Arduinos. The DCPU specification goes over the operations required of any DCPU emulator. There's a lot of crazy stuff here - a division instruction that takes only … [Read more...]
