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.
In an act of delicious over kill, these guys threw a pizza into an industrial laser cutter. The result? Exactly what you would expect. Smoke, giggles and perfectly cut pizza. It looks like the cheese stuck together a bit after the laser cut, but that happens with normal pizza cutters too.

While we hope you enjoyed our How-To: Etch a printed circuit board, toner transfer certainly isn’t the only way to get the job done. [Garrett] from macetech has recently been playing around with using an Epilog laser to etch PCBs. He started by applying a thin even coat of flat black spray paint to the copper board. The laser is used to remove paint in areas that you want the copper removed. Once that’s done, you proceed with etching as usual. He eventually removed the paint mask using acetone. The result has very fine, sharp traces, but most people that have tried this agree that using spray paint is less than ideal.
Radiohead has released their music video for “House Of Cards.” We’ve already covered some of the tech involved. If making an entire video without cameras wasn’t edgy enough, they’ve released all the point data for people to play with and remix. The band is encouraging people to post their creations to their YouTube group.
Head over to their Google Code page to watch a making of video as well as view some of the datasets in 3D. There is a link to the entire dataset for download as well.
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.

[Radiohead], being no strangers to out of the box delivery ideas, are preparing to release a new video that was created without the use of cameras. The entire video for the song House of Cards was “filmed” using lasers.
The system, known as Geometric Informatics and Velodyne Lidar, scanned the entire environment 900 times a minute to capture an entire party in real time.
The video was originally set to be released in mid July, but appears to have been moved back.
[andre] sent in his first attempt at using a HD-DVD laser diode to expose photosensitive resist to create PC boards. We’ve been meaning to give this a shot with the ol’ Epilog laser cutter. For the test, he coated the board with some resist and hand exposed it with the laser. Finally, he etched it with some sodium hydroxide.
