[rog8811] sent in this really cool hack where he used the optics sled from a PS3 as a foundation for a 7 color hand held laser projector. Combining a green laser, a blue ray laser, and a red laser, he is able to produce a variety of color  including white. There are step by step instructions on how to make a multicolored laser. He then goes even further, showing how to integrate this into a hand held projector with pre programmed patterns. You can see some examples of the different colors and patterns in this video.

Laser Cut Pumps

As the video above shows, [Zach Hoeken] is continuing to improve on his peristaltic pump design. The moving parts in peristaltic pumps never contact the fluid being moved. Instead, they interact with the outside of the tubing that’s carrying the liquid. In [Zach]’s design, multiple skate bearings roll across the outside of the silicon tubing, squeezing the liquid through. You can get a better idea of how this works by watching the first video. The newer version appears to be pumping much better. We’re not sure if that’s because of faster motors or from switching to two bearings instead of three. This definitely looks like a good choice if you’re planning on building your own cocktail robot. You can find the plans on Thingiverse.

Laser POV Projector

September 23, 2008 by 10 Comments

[shakirfm] sent us this LED persistence of vision (POV) laser projector that can display dot matrix style text. The laser projector contains a rotating mirror assembly and 5 lasers. We’ve covered other POV projectors,but this one is a bit different. The mirror assembly rotates using two cooling fans. Controlling on/off times of the lasers along with the mirror speed, it is able to project 8×5 dot matrix ASCII text onto a surface.

Turn Your Projector Into A Laser Guided Controller

[Alpay Kasal] of LitStudios as come up with an interesting way to use laser pointers as a wireless controller for games and applications. The process is currently being patented, which may explain why [Alpay]’s blog is a little slim in the details. We doubt they’re doing anything more than just using a camera to track the laser pointer; exactly like laser tagging.

If you’re just itching to get your hands on some wireless game play and can’t wait for this to go commercial you could always just get a Nintendo Wii.

James Powderly Released

August 25, 2008 by 10 Comments


Graffiti Research Lab’s [James Powderly] along with 9 other Tibet supporters were deported from China during the Olympic’s closing ceremonies. Detained on the 19th, the activists were to serve a 10 day sentence, but the Chinese government buckled under international pressure and deported them early. This brings the total number of deported activists to 53 since the start of the games.

Graffiti Research Lab is well known for its laser tagging research.

Fun With Radiohead’s Data From ‘House Of Cards’

July 21, 2008 by No comments

Radiohead recently released the 3D data that was used to create the video for their song ‘House of Cards‘. [Micheal_z] sent in some of the results of his groups playtime with the data. The first effort involved some data translation. Then they created an atomizer of the head and put it up on their ungodly huge 8160×4000 pixel multi-touch display.

The video below was created by tracking the background image to orient and overlay the projection.

Epilog Zing Personal Laser Etching

July 12, 2008 by 13 Comments

The new Epilog Zing is designed to bring laser engraving to the home for personal use. It’s got 25 watts of power, a small enough footprint to fit neatly on your desk, and the video above shows it has a pretty high resolution. But compared to the mini18, the Zing has less Z movement, a lower wattage, a smaller engraving area, and about half the speed. Also, with a price set around $8,000, we don’t think many people will be buying them for personal use just yet. However, if you have a small home business that requires these services, the Zing could be perfect. If you are looking for more information on laser engraving, see [ladyada’s] laser information page.
