Fresh hacks every day
[Vinod Stanur] is working with a mouse input and a microcontroller driven LED matrix. The mouse cursor is tracked inside of a window by Python and the resulting coordinates on the LED grid are illuminated. He calls it an LED matrix "Paint Toy" because one of the features he's included lets the user create pixel art like in MS Paint. The 10x8 grid of lights is controlled by a PIC 16F877A. This … [Read more...]
[Gagandeep] was sick and tired of discourteous drivers on the highway, so he decided that he would put together a display to let them know what he thought of their poor driving skills. He planned on putting the display up in the rear window of his car, so he had to ensure that it did not obstruct his view while driving. He decided that an LED matrix would be the best way for displaying images … [Read more...]
At Hive13, a Cincinnati-based hackerspace, they like to hack everything - even their bathroom. One of the bathroom’s walls faces the street, and is made up of thick glass privacy blocks. A few years ago, they thought it would be a cool idea to install an LED matrix to the back side of the glass wall to spruce things up a bit. After a couple of iterations, they finally had something they were … [Read more...]
[vinod] sent in his replica of a Snake game, the game to play on old Nokia dumb phones. The build is based on a PIC16F877 microcontroller just like previous Snake builds we've seen, but [vinod] didn't use physical buttons in his build. Instead, he used a Philips infrared TV remote to control the game. The infrared controller only takes up one pin on the microcontroller, as opposed to the 4 pins … [Read more...]
[yergacheffe] was able to get his hands on a shiny new Google ADK board about a week before it was announced at I/O, and got busy putting together a neat project to show off some of the ADK’s features. His idea was to meld together the ADK and Google’s new music service, two items he says complement each other very well. He had a handful of LED matrices left over from last year's Maker … [Read more...]
The Revision 2011 demo party that brought us" table for two" a little while ago along with some super demos for PC's, retro, and state of the art, has also brought us the Photon Banner(google translate). The Photon Banner is a 96X24 led matrix that was made with (of course) 2304 5mm leds, and a atmega 644 clocked at 20MHz. The end result is a 192cm X 48cm display area that uses the single micro … [Read more...]
Papydoo spends most of its time sleeping, but if startled by vibration it will wake up and stare you down with a cold and unnerving robo-gaze like you have not seen before. Or it might just do something crazy like display a scrolling Space Invaders character marquee. That’s the thing with Papydoo, you just never know. Vibration sensing is accomplished with a piezo element harvested from an … [Read more...]
