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.

Notes

    Where To Get Parts).

  1. This ciruits is NOT isolated from ground. Use caution when operating without a case. A case is required for normal operation. Do not touch any part of the circuit with the case open or not installed.
  2. Most any diodes rated at greater then 250 volts at 1 amp can be used instead of the 1N4003's.

Where is the missing information in the "NOTES:" for the following from the parts list? (T1 1 4KV Trigger Transformer (see "Notes") FT 1 Flash Tube (see "Notes") )

(Editor's notes: Oops. Will correct with the next update. But both a generic parts. Any 4KV flash trigger will work, any small Xenon flash tube will work as well.)

Hi there. I need to find a good way to build a strobe light circuitboard that is portable. i am doing mosquito research w a university, and we are testing electrophysiological responses. i am trying to see the effects of a strobe light, and so i need a portable strobe light device that is low-voltage and long-lasting (typically for 12 hours at least) and safe for other students to handle. any suggestions guys?

a very good website i really love it, i enjoy building up projects from the circuits, it help me practice for my A level electronics. COULD you please help me to HOW to build up a circuit for Security light.i want it to light when something move next to it.it has to light up for few second and then automatically turn off. PLEASE would u help me i really need your help. THanks

There should be a resistor in series with the AC line to prevent a half cycle of the AC from coming through and blowing the tube like so: http://silenceisdefeat.org/~lgtngstk/Sites/Strobe/Strobe.html. I learned this the hard way. Cheers

(Editor's notes: Just a note that I've had several of these circuits operating for more then 15 years with no resistor.)

I'm working a project to make a slave strobe. I see your "slave" circuit, know it is supposed to plug into "somewhere", and have looked at your "strobe" circuits, but cannot "visualize" how to merge the two together. Could you possibly send me an example of a functional combined circuit, please? Thank you. Keep up the good work ! Sincerely, Chris

i wabnt using 220 V AC, can i get a flash lights. are 4700 microFarad is enough to get the light bigger? how can i get T1 (4KV)
