Xenon flash valve - An experiment of the xenon flash valve. (added
10/05) |
Xenon Flasher (Colin Mitchell) - 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…. |

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
(ESP)] |
Xenon Strobe Light (Aaron Cake) - 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. |
Xenon Strobe Light (Linscott) - 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 ….(added 5/02) |
