Touch Activated Switch - This circuit provides about one watt of non-isolated DC power for an automotive type 12v
LED array lamp in addition to a standard incandescent table lamp.[. . . Circuit by David A. Johnson

Transmitter
for Line Powered Xenon Flash - This line
powered xenon flash circuit drives a small camera type flash tube. It has an optical isolator to allow
the flash to be safely triggered from some remote device. A flash rate of 2Hz is possible with the
circuit[ . . . Hobby Circuit designed by David A. Johnson P.E., 06/09/00]

Xenon
Flasher - You are going to like this project. It
costs less than $3.00, contains six BUILDING BLOCKS, re-cycles a disposable flash camera and you are
going to learn a lot about electronics.
Everyone has seen a disposable flash camera. [Colin Mitchell]
Xenon Lamp Flash
Detector Amplifier - This circuit has a very
low standby current requirement yet has very high sensitivity toward the light flashes from a xenon lamp.
When connected to a flip/flop it can serve as an on on/off Controller[. . . Circuit by Dave Johnson

Xenon Photoflash Controller - This 9v battery powered circuit is designed for remote control flash needs. A charge
control circuit turns off the high voltage generator when the photoflash capacitor is fully charged. A
neon lamp is included to indicate when the system is ready to flash[. . . Circuit by David A. Johnson

Xenon Strobe Light - Disco anyone? Actually, this strobe serves a much more useful purpose then making it look
cool when you dance in the dark. You can use it to view fast moving objects, look for craks in PC boards
(hold the strobe on the trace side of the board and look from the component side) , and it is a great
attention getter in a store window. [Circuit designed by Aaron Cake]
Xenon Strobe Light - The way that this circuit works is as follows. The AC line voltage is rectified by D1 and
D2 which connects to a voltage doubler circuit made up of the two 22uf capacitors. The Flash Freq. Pot
and the 10uf capacitor charge up which triggers the Diac. [Circuit by Randy Linscott]
Xenon Strobe Light - A xenon flash tube is a triggered gas discharge device. A voltage may be impressed across
the tube and it will not conduct until the xenon gas is ionised by an external high voltage (typically 3
to 5kV). Once triggered, the gas becomes a very low impedance, and discharges the storage capacitors in
about 1ms (this varies considerably, but this figure is fine for basic calculations) [Rod Elliott
