Title: Plasma lamps
Post by: Scott on October 18, 2000, 10:27:00 am

In high school physics,we built an economy version of the plasma lamps you see in stores like Spencer's. The bulb was a burned out 300 watt clear bulb,the base being one contact,a piece of foil glued to the top(with a thin layer of silicone caulk)the other. A simple HV circuit made from an ignition coil drove it, and the results were not as good as a commercial one, but interesting just the same. Colors,obviously,depended on the gasses in the bulb. It's worth trying,and makes a neat Halloween display.

Hey Scott!

You mean something like this? I used an old HV high frequency quack wand and a burned out bulb, something like a gasfilled Mazda C, and got the following results.....I always called it the poor man's plasma dome  (http://www.bulbcollector.com/ubb/smile.gif)
