Fresh hacks every day
This little device lets you play some head-to-head pong using a spinning LED display. We’re really in love with the design. You get a pretty good idea of the Persistence of Vision aspect of the build by looking at this picture. But hearing [Dennis] explain the entire design in the video after the break has us really loving its … Read the rest
The concept behind this clock has been seen before, but [Dieter] tried to combine the best aspects of several projects into his HDD POV clock (translated). The basic principle of the design is to cut a slot into the top platter of the hard drive. This will let the light from some LEDs shine through. By carefully synchronizing … Read the rest
If you don’t mind working with really small components this POV wheel project for a longboard will certainly attract some attention.
The name of the game here is small and cheap. Small because the wheels are only 72mm in diameter (about 2.8 inches). Cheap because [Ch00f] wants to produce and sell them locally. He went with an ATtiny24 microcontroller driving … Read the rest
Building a Persistence of Vision globe is pretty awesome, but overlaying a Death Star pattern on the display takes it to the next level of geekery. Like us, [Jason] has wanted to build one of these for a long time. His success pushes us one step closer to taking the plunge and we hope it will inspire you to give … Read the rest
Watching Big Buck Bunny on a spinning POV display is pretty impressive. Sure, the circular display area cuts off some of the picture, but otherwise it looks fantastic. This POV display is based on a Gumstix board. It runs embedded Linux which makes video playback rather easy. But translating each frame to the round display is another story.
The device … Read the rest
Being an intern a Texas Instruments isn’t all fun and games, but from [George], [Valerie], and [Ryan]‘s TI intern design project, it sure looks like it. They built a persistence of vision display for a bicycle using the ever popular MSP430 Launchpad board.
The team of interns created a POV display by combining the power of the TI Launchpad with … Read the rest
The more we think about this one the more we like it. [Michael] built himself a wind-powered persistence-of-vision weather station. Okay, that sounds interesting, but he ups the ante when you find out what’s included in the system.
A stepper motor acts as the generator which powers the electronics. As we’ve seen before; if you spin the shaft … Read the rest
