This is a beautiful take on a regular old alarm clock. It should inspire people to look under the covers and cases for the inner beauty that lurks within (ooo, impressive, eh?).

DIY Nitrogen Laser
Everyone is talking about this today. I remember first read about a free nitrogen laser in the Scientific American Experimenters Handbook when I was a teenager. I was more into building a Van de Graff machine but I could still appreciate a laser that didn’t need any complex lasing fluids or expensive tubes or one of those ultra cool multi Joule flash lamps. Ahh.. Such day dreams those made up… Oh yeah, about the laser. Pretty much is uses a great whopping spark to excite the nitrogen atoms in the air to a higher state and in turn that liberates ultraviolet radiation. Cool, eh? Hubert’s page has all sorts of cracking info on how that darn thing works, the kid did his homework Looks like you could build one for less than $50 easy. The 10KV power supply could be obtained from a TV or you might even be able to get away with using one of those cheesy air ionizers you find in second hand shops. Or you could buy one from Information Unlimited. (Weird, I Googled ‘high voltage power supply’ and saw the link, I had no idea those guys were still around! Very cool!)

CSSoh’s Lego Pneumatics
What do you get when you add air to your LEGOs? No, not crispy LEGOS that don’t go soggy in milk, you get power! This site has all sorts of methods of building motors, valves, and switches that run off from pressurized air and all are made with that classic building material, LEGO. YOu know, it’s not too late to order some
Millimeter Wave Active Denial System
Ouch! The effect of this device is to make it feel like your being melted.
The ADS shoots a beam of millimeters waves, which are longer in wavelength than x-rays but shorter than microwaves — 94 GHz (= 3 mm wavelength) compared to 2.45 GHz (= 12 cm wavelength) in a standard microwave oven.
I wonder if I can get one in a flashlight form factor…

PXL2000 User Manual
A reader posted a comment today on where one might obtain a copy of the users manual for the retro niche video camera of artists, the Fisher-Price PXL2000. Now, if your into the indy avaunt guard art movie scene you know what this is. If not it was a video camera marketed to kid that recorded a cropped blocky black and white image onto a standard audio tape. Wild eh? I’ve owned a few (I did the A/V mod on at least one thank you) and they are a blast to play with. I even removed the IR filter in hopes I could make a night vision scope for playing paintball. Eh, I was young…
Air Wells, Dew Ponds and Fog Fences
My friend Greg sent this to me the other day. It’s a great read if your into water, which I can safely say we all are. The article is quite through on the many aspects of gathering the moisture in the air and even inducing precipitation (although I don’t think I’d bet the farm on the Orgone methods).
