ToorCamp recently funded Hackerbot Labs' proposal for building a laser that will project a static column of light into the sky (think Luxor or Tron) as part of their Laser Camp @ ToorCamp. They're doing this by extracting the laser module out of a casio 'slim' projector that happens to have 24 1-2watt 445nm (blue) lasers with optics and using all 24 of them to create the Photonic Beam! The picture shown to the right is their first test of only 1 of the lasers -- you can use your imagination to fill in how this scales to 24!
The HBL team (especially 3ric Johanson) are extremely well versed with lasers both professionally as well as other projects they've done at HBL so they're making sure to use the utmost safety precautions, following all laser safety regulations, and of course applying for the proper clearances from the FAA.
We're super excited about this project and look forward to posting updates on it as we get closer to the camp. Hackerbot Labs, you guys rock!
