[Joe] sent us this project called Laser Pup.  After seeing many other projects with the ioBridge like beer pouring and dog treat dispensing, he wanted to make his own. His project allows him to play with his dog via a ceiling mounted laser pointer. We know, you were hoping for something more along the lines of Laser Cats, but this is still pretty cool. He built a web interface specifically for the iPhone to control the laser, room lights, and show a live feed of the puppy playing. You can see a video of it in action after the break.

[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.

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.

Laser Based Night Light

June 15, 2008 by 5 Comments


[the4est] put together this quick how to for making a laser based light bulb night light. First, you need to break out the black glass base of the bulb and remove the filament. Scrub the inside of the bulb and pour in the paraffin. Once it sets, you can break the glass, leaving a solid wax bulb. Hollow out the inside, insert a laser pointer, and you’ll have fine glowing night light.

Interactive Laser Drawing (graffiti)

May 26, 2007 by 14 Comments


This hack was linked a bit back in February, but it just didn’t get a decent write up. They used this 5000 lumen projector, a zoom lens video camera and a 60mw green laser pointer to generate interactive graffiti on nearby buildings. Most of the link love focused on the show-off video. I’m surprised that nobody mentioned the most obvious use: a laser pointer reactive white board. I could have loads of fun with this and my laptop during presentations. Thanks to [Brishen] for reminding me of this one.
