Produces 8-12" Visible Lightning-Like Discharges. Both the kit and assembled unit include an 8" toroid and wound coil (so you don't have to do any winding). Excellent Science Project. Easy to build. Fully adjustable.
|Downloadable plans: 40 pages with schematics and color photos.
It is also available assembled, or as a kit with plans and all parts requiring assembly.
This is a spark driven Tesla coil generating highly visual and audible sparks into open air without a return contact.
The unit operates from a standard wall outlet requiring less than two amps. The transformer is current limited to 60 ma and center point grounded.
The tesla coil is easily tabletop operable and is a two-level assembly consisting of a top and bottom section. The top supports the vertical mounted secondary output coil and the flat Archimedean spiraled primary along with tunable clip lead. The bottom supports the transformer, capacitor and spark gap assembly. A metal control panel is connected to earth ground along with the secondary return minimizing any dangerous shock hazards.
The spark gap uses two pure tungsten electrodes rarely requiring cleaning or dressing. Hardware is all brass where required, with the primary coil being a hybrid between copper tubing and a heavy insulated wire.
The kit version contains all parts to complete the unit, including a pre-wound and fully prepped secondary coil, and an 8 x 2" toroidal terminal which greatly adds to the performance and overall appearance of the completed system.
Assembly: Mostly mechanical assembly with some soldering.
Applications: use for a science project, special effects prop, research of high frequency electricity, and much more.

We find the BTC30 from Information Unlimited has all of the functional parts for a basic 250 kV Tesla Coil. It is reliable (as long as it is not modified beyond the specs recommended by the company) and lasts for years. Having the downloaded plans is great, especially since they are well drawn and easy to follow.

As advertised. They are the plans.
