Run As A Jacob's Ladder
Turns A Normal Light Bulb Into A Spectacular Plasma Display!
Build a Plasma Tornado, Demonstrates Pyrotechnic Effects
Solid-state Tesla coil using readily available television fly back transformers and operating from 12 volts DC (from either a battery or 115-vac wall adapter, not included). Versatile circuit can be used to make a Jacobs's ladder, plasma tornado, wireless energy demonstration, pyrotechnic electrical display and even turn a normal light bulb into a low-cost plasma globe.
|Paper plans: 20 pages of schematics, instructions, and experiments (also available as downloadable plans for roughly half the price).|
Unit is built onto a plastic channel of 7.25 x 2.5 x 3" with a coil enclosure of 5 x 3.5" diameter. All controls are on an aluminum front panel and include a fuse, power switch and power control. Operation with light loads must be done with caution as open circuit voltage will soar at resonance and cause the output transformer to burn out. When the unit is operated as a Jacob's ladder or connected to a large neon display it may be left on indefinitely. Unit is fully short-circuit protected.
Assembly: Wire and soldering to a printed circuit board with some basic mechanical assembly.
Applications: Use as a high frequency high voltage generator for research, conversation piece, special effects prop, and office or bar action decoration.
In lightbulb mode, it uses a 5" clear 100W 'DECOR' bulb (not included) which may be found at your local hardware or home decorating store.
Amazing and bizarre effects!
Excellent science project!
You provide the power supply from a 12v battery or wall adapter (not included); or you may purchase one of our recommended 12V power supplies:
Optional Neon Tubes to demonstrate wireless energy transfer:
NE12U - 24" of neon tube in a 12" U-shape (available in a choice of colors)
