Hubert's $10 Air Laser

Well for Xmas or New Year we certainly do like some laser lightening shows, but buying a laser isn't so feasible in the middest of so much expanses of holiday. A French geek came up with a "built it yourself" idea, which will cost you just US$10 to build your own air laser.
I like the idea of very simple laser: no special gas, no chemical products, no vacuum and no glass work! This Nitrogen laser uses normal air at atmospheric pressure. All you need is some metal parts and an about 10 kV 1 mA adjustable High tension DC source.
Hubert (the name of the Geek) utilize the theory of Nitrogen molecules in air to lase. Ordinary Nitrogen laser uses low pressure wide channel nitrogen like the old very well known "American Scientist" Nitrogen laser project: http://www.montagar.com/~patj/n2lmnu.htm
The whole air laser is based on a rectangular A4 aluminum plate on which is disposed a rectangular A4 plastic sheet. 2 aluminum plates act as capacitors and 2 other pieces of metal are used as electrodes for plasma channel. 2 U aluminum parts screwed on the main plate can hold all that with Nylon screws. Nylon screws get electrical insulation and allow user to very easily change, modify or adjust plates, electrodes or plastic film. A4 plastic film is a low cost very easy to find/repair dielectric solution.
Hubert describe step by step of making this remarkable, yet very easy to built your own air laser device. You don't have to be a genius to follow those instruction, he described all the steps in simple non-geeky english. So if you gather the stuffs and follow the instruction few hours laser you will have your device up and running.
