We pretty much don’t know anything about this POV device other than it uses 96 LEDs. We’ve seen POVs with more LEDs, but usually they aren’t packed in so tight. This thing looks almost capable of displaying low res movies. Wouldn’t this thing be cool, and probably dangerous, in a hat?

Every year, as it gets cold, many of us put our faithful two wheeled companion away for the winter. Despite that, there have been a veritable smorgasbord of bicycle related projects posted to instructables this last week. In honor of our human powered transportation, lets take a peak at a few projects.
Bicycle safety is always paramount. They can be fairly difficult to see compared to a car. There are many ways to make them easier to spot, such as wrapping them in reflective material, or adding blinking tail lights. Even if people do see us, they often have no idea where we are planning on going. To remedy this, we can always add turn signals. It can also be hard to see where you are going at times. Adding a head light, or helmet light can really help. If you’re not a big fan of LEDs and want a little retro flair, you can always add an oil lamp.
For those who live in warmer climates, or just can’t give up their bicycles, you may wish to add some festive decorations. Covering your bike in Christmas lights doesn’t look too difficult, and a CFL lit wheel is a cheap way of adding some cool effects.
[Mario Mauerer] and friends were commissioned to build this 2m persistence of vision display (translated) for a party (in a hight-voltage lab no less). Dubbed “Display from Hell”, it uses 100 blue SMD LEDs to generate the POV images. They’re connected to an ATMega64 via shift registers. Their target speed is 600rpm for a flicker free image, which means the propeller tips are moving at 140mph. The board can be updated wirelessly via IRDA and plans for adding SD storage are in place. You have to see and HEAR this thing in the video embedded below. Continue reading “Stupidly Huge POV Display”

[ricosgoo] wanted a way to stand out at his graduation. We think he succeeded with his graduation gown VU meter. After putting the circuit together at the last minute, he made a mounting harness out of duct tape. The electronics hang like a sash, placing the bulk under his arm where it won’t show through his gown. He mounted a mike towards the neck line so it reacts best to his voice. It was a hit, apparently strangers would come up and make noise just to see the meter go off.

Add lights to your graphing calculator. Do it now. [Sil3ntP8nd8] added some, and seems to have done a decent job. They are spread around the back, supplying a nice even light on, well, on whatever is under your calculator. It may be difficult to see too much detail though on account of the water marks. You have to protect your intellectual property though. This almost compares to the DS LED monstrosity we covered recently.
[Brian] made this really cool LED keyboard. He started with a Deck Legend Fire. When he got it, he realized that every key had its own LED, but the entire unit was either on, or off. He just couldn’t live with that and decided to start hacking into it to make each light individually controlled. He found a perfect empty space in the back of the keyboard and designed custom PCBs to control his lighting. he notes that he spent 12 hours of cutting and soldering wires to each of the lights in the keyboard, that doesn’t include the PCB construction.
In the end, he had a fantastic looking keyboard that had cool effects like heat mapping and idle animations. All stock features still work and it looks almost entirely stock. The only obvious difference is the fact that it has two USB cables coming out of it due to some issues with his KVM switch not detecting it.

Adding LEDs makes everything better. Watch this video as a regular old DS gets turned into one of the most awesome things on the planet. A ton of LEDs were added, some to the body, some to an extra cartridge, some behind buttons. Parts are wired into the speakers, so you get nice effects to your music. We’ll bet the battery life suffers, but who cares. This thing is worth it. This was originally taken from Nico Nico Douga, which overlays the comments on the video.
