| High
Voltage Power Supply Kit |
 Universal
high voltage power supply kit. This HV power source
may be used in a variety of different high voltage
applications, like:
kirlian photography
HeNe Laser tube power supply
x-ray tubes
plasma tubes
negative ion generators, etc.
Features variable frequency using a potentiometer.
Also has a High-Low frequency range switch.
In addition this circuit to be either battery powered
12 VDC, or powered from a wall transformer also
12V with either an AC or DC output.
When powered from batteries provides the advantage
of portability for fieldwork.

Wimshurst Machine |
 This
machine produces large static electric sparks for
a terrific classroom demonstration. No assembly
required, simply attach the hand crank, begin cranking,
and watch in wonder as the sparks fly. Instruction
guide and helpful hints are included with each unit.
Unit consists of two high resistance 25cm plastic
discs, with equally spaced metal sectors. The discs
are supported in two rigid upright supports, rotating
in opposite directions with a hand crank. Provided
with a system of induced charge collecting brushes,
adjustable ball-ended electrodes, and cylindrical
Leyden jar capacitors for obtaining higher potentials.
Produces substantial opposite charges, which are
deposited in the capacitors and on the metal spheres.
A rapid sequence of sparks can be generated by lowering
the system capacitance (moving the metal spheres
closer together).
Mounted on an insulated wooden
base.

| Ion
Generator |
 Generates
negative ions and blows air without any moving parts.
High voltage negative ion generator generates “ion
wind” without a fan or moving parts. Wind is generated
by force of ion repulsion. Similar in principle
to the ion propulsion systems used by NASA in modern
spacecraft. Generate negative ions for health and
airborne pollution removal in small areas. Kit includes
7.5kV DC negative power supply at 400 uA, 7 ion
wind tubes and mounting hardware for the ion wind
generator.

| High
Voltage Plasma Generator |
- Generates 2” sparks to handheld screwdriver
- Light fluorescent tubes without wires
- Build your own Plasma Balls
- Generates up to 25kV @ 20 KHz from solid state
circuit
Solid state high voltage power supply is perfect
for high voltage experiments, like Kirlian photography.
The high voltage at the terminal won’t electrocute
you, so its relatively safe, but it can burn you,
so use caution. Can be run from 5-24 VDC so the
output voltage can be directly adjustable.

Kirlian photography device
These include the on/off power switch, discharge
switch, Hi-Low frequency switch and variable frequency
control. The discharge plate is located on the left
hand side of the device. The terms discharge
plate and film plate mean one and the same.
The on/off switch provides main power to the circuit.
discharge switch is a momentary contact switch that
applies the electrical power to the discharge plate.
The frequency control varies the frequency of the
electrical power going to the discharge plate.
This device is designed to work with all 4" X
5" color, b/w 4" X 5" sheet film and paper.
as well as polaroid film.
