Fresh hacks every day
Sometimes a pair of extremely similar builds hit the Hackaday tip line within hours of each other. We're not one to play favorites, so here's two projects that put RGB LED strips in a desk and workbench. [Charles] over at The Makers Workbench has long needed a lighting solution for his workspace. Flourescent lights are alright, but for real geek cred nothing but LED strips will do. He picked … [Read more...]
Building RGB LED displays is one of the most interesting programming and engineering challenges we see here on Hackaday. Not only do the creators of large displays and LED cubes have to deal with the power requirements of driving a whole bunch of LEDs, but there's also the issue of getting the frame rate high enough to display video. It's a non-trivial task, but [Paul Stoffregen] has an … [Read more...]
[4RM4] over at the Stuttgart hackerspace Shackspace ran into a guy selling individually addressable RGB LED strips when he attended the 29th Chaos Communication Congress last December. He had a Raspberry Pi with him, and after a little bit of work he rigged up an LED display that wrapped around a trash can. A respectable hack, but not quite ready for prime time. After getting back to the … [Read more...]
Sure, it's time to get the countdown clocks ready to ring in the new year, but why limit it to just one night? If you end up building a six-foot digital display you can count down trivial events; like the remaining seconds of freedom before you have to pimp yourself out in that drab cubicle. This seven-segment display is homemade and boasts six full-sized digits and two smaller digits with each … [Read more...]
Needing a Christmas present for his 4- and 5-year-old nieces, [John] built a one-dimensional PONG game, sure to be the delight of rosy-cheeked children on a Christmas morn. The new and improved 1D PONG game is built around a digital RGB LED strip with an LPD8806 LED controller. The speed of the 'ball' is controlled by a pot on one side of the game. With each player pressing their button at … [Read more...]
After adding a few LED light strips above his desk, [Bogdan] was impressed with the results. They're bright, look awesome, and exude a hacker aesthetic. Wanting to expand his LED strip installation, [Bogdan] decided to see if these inexpensive LED strips were actually less expensive in the long run than regular incandescent bulbs. The results were surprising, and we've got to give [Bogdan] a hand … [Read more...]
Quit struggling with hastily patched together electronics for your light painting images. Follow [Madox's] example and build a light painting wand designed with your hand in mind. You wield it much like a sword, but the only damage it does is to the long-exposure camera pointed its way. The RGB LED strip is controlled by the guts of a tiny little wireless router, a TP-Link TL-WR703N. This lets … [Read more...]
