Fresh hacks every day
Registering a mutant vehicle at the Burning Man Department of Mutant Vehicles (DMV) is rough. To be allowed to operate at night, wacky rolling creations have to have a certain degree of lighting presence. This keeps vehicles from blending into the scenery. Unfortunately Mirage 1.0 was built specifically with this in mind, using reflective surfaces to turn a van into a semi-invisible shiny … [Read more...]
What do you do if you see a bunch of 14-segment LED displays for sale for a penny a piece? [Fritzler], when faced with that conundrum did what any of us would do - he bought 64 14-segment displays and built a huge 16x4 alphanumeric display (German, here's the translation). [Fritzler] found a cache of old East German 14-segment displays for €0.01 at electrobi.de (don't bother, they're out … [Read more...]
After [Ch00f] got his hands on an 8x8 LED display, he didn't make a 64-pixel video game or VU meter. He made a laser doodler, allowing him to draw on this display with only a laser pointer. Using LEDs as light sensors is nothing new; [Forrest Mims III] discovered that LEDs can also detect light way back in the late 60s. [Ch00f] played around with this concept before creating a circuit that … [Read more...]
While huge LED panels are a relatively common project du jour for people wanting to flex their engineering muscle, we're taken aback by the sheer beauty of [Skot9000]'s huge LED display made of seven-segment displays. He calls the build DigitGrid, and it's a wondrous display the likes of which we've never seen. To build a display based on seven-segment LEDs, [Skot] went with a modular approach … [Read more...]
We're throwing money at our monitor and nothing's happening! Sometimes we get hacks sent into our tip line that are outrageously awesome, but apart from a YouTube video we've got nothing else to write about. So begins the story of the flying Back to the Future DeLorean quadrocopter. Sadly, the story ends with the video as well. (If you've got any info, send it in!) Fine, we'll throw in … [Read more...]
