SCIENCE PLANS

Please Note:  Plans do not include any parts!!!

PLAN21000 - TESLA COIL

This science project shows how to construct a Tesla Coil using a step-up transformer. The completed project will produce up to 250,000 Volts, giving spectacular 6"-12" sparks of continuous high frequency energy. Great for science fair projects.

PLAN21000 - Tesla Coil ................................. $12.95

PLAN21001 - BINARY COUNTER

Using a cascade of flip-flop circuits and indicator lights, the state of each stage of this counter may be observed visually. You can demonstrate binary mathematics, addition, etc. Makes a good science fair project.

PLAN21001 - Binary Counter ........................... $12.95

PLAN21002 - SOLID STATE GEIGER COUNTER

A Solid State approach for a Geiger counter to determine relative radioactivity of different materials. A simple one night project. The printed circuit pattern permits quick completion of this highly accurate professional use Geiger counter. Additional circuit patterns included to add digital readout to the radiation's indicator. Relative radiation is indicated by audio output of a piezo-electric sound element.

PLAN21002 - Solid State Geiger Counter ......... $12.95
Also available as a Complete Kit.

PLAN21003 - NEGATIVE ION GENERATOR

Similar to commercially available ion generators costing $50-60 dollars. Build your own and save. Eliminates smoke, pollen, smog, etc. from your air. Breathe easier, be healthier. Easily built in one evening.

PLAN21003 - Negative Ion Generator ............... $12.95
Also available as a Complete Kit.

PLAN21004 - UNIVERSAL TIMER MODULE

This timer module could solve all your circuit timing needs. Small printed circuit board makes an easy to build and use module. Will produce timing delays or intervals from microseconds to hours! Board has provisions for either negative or positive edge triggering and will drive up to a 1000 MA load. Timing is adjustable with an on-board potentiometer and jumpers. Operates astable or monostable. Re-triggerable and re-setable. Can be used as square wave oscillator.
