Ion Chamber Bias Supply (Battery Topper) - After discovering that one of my bias
batteries was jumping around a few volts, wreaking havoc with the readings, I decided
to build a floating, regulated high voltage supply. The result is a micro-power 110
volt supply that runs on an ordinary 6V lanternt...(added 08/08/08) |

Jacobs Ladder (Tony van Roon) - People have long been fascinated by electric
arcs--and perhaps put off by them. They show up as lightning, Tesla coil
discharges, and long sparks that sting as you reach for the doorknob on
a cold, dry, winter day. This Jacob's Ladder project turns electric arcs into a
dramatic but harmless conversation piece....(electronic design / schematic added 2/06) |
|
Jacob's Ladders (mistertippy) - A Jacob's Ladder does not serve any real purpose
other than that it shows the properties of an electric arc, or as a visual display. It
is composed of two vertical rails that are close to one another at the bottom and
gradually spread out, forming a "V" shaped structure. A sufficient voltage to
breakdown the air gap at the base of the "V" is applied to the two rails. As the
ionized air is heated, the arc begins to rise with the more conductive hot
air.....(electronic Circuit diagram added 03/03/03) |

Line voltage negative half-cycle trigged high voltage pulse generator - This
circuit generates high voltage pulses from 230vac line voltage. The drive end's swing
comparator circuit is invented by the creator of this page. The work end is derived
from stroboscope trig supply circuit. All line voltage using circuits are inherently
dangerous, and this is particulary so. Do not build it. (added 06/09) |

Low Power 12,000 Volt Power Supply - If you need about 12,000 volts DC for an ion
generator this circuit might be the ticket. It draws power from the 120vac power line
but it uses a small 6KV camera flash trigger coil. The output signal is isolated from
the power line. Although the circuit can only deliver about 5uA of current it can
produce dangerous shocks, so be careful. ….(designed by David A. Johnson) |

Super Cheap 1500 Volt Power Supply small Laser Supply - This little power supply
uses an ordinary 120VAC to 9VAC step-down transformer to deliver 1500Vrms. You will

transformer is wired backwards. 9V windings connect to 120V.... (circuit /

Tesla coil/ HV generator - Caution! This is a fun and useful circuit for
demonstrating high frequency high voltge. It can produce up to about 30KV, depending
on the transformer used. It is cheap and easy to make, thanks to the standard TV
flyback transformer used. It can power LASERS (although I have never tried),
demonstrate St.Elmo's fire, and even cause a fluorescent bulb to light from as much as
2 feet away. (circuit added 06/07) |
