This Adjustable Strobe Light is the bigger brother of the plain old strobe light. This one uses a much more powerful "horse shoe" Xenon tube which produces more light. You can also control the flash rate up to about 20Hz. Do not look directly at the flash tube when this thing is on!

|HI...I would like to ask that can this circuit be solder on a stripboard?? as i would like to make it increase the speed of flashing when i press the button increasing by time and can the flash stop and continuing lighting the light without flashing after a long pressing on the button??
|the xenon should be rated at how many watt ? i am going to waor this circuit in 240v and i had removed the doubler (C1 & D1) how many volt n watt required for the neon bulb to discharge the capasitor ? last, the ground pin or primary pin of the trigger transformer is connected to SCR ?
|What determines the power output to the flash tube? How is the capacitor value determine in a voltage doubler. Say I want to power a much larger flash tube.
|What are the changes required for the circuit to work on 220V
(Editor's notes: Remove voltage doubler.)
|where is a good source for the SCR ? the high V cap ?
|I know what an 106 SCR is, but I can't it. Could someone help me?
|what volt battery does it run on?
|Very helpful. Just a quick question, how do I do this on 220V? Best regards, -Max
|Hi all. Just to answer some questions you might have about the neon light. Since the circuit runs (thereby charging the capacitor) as soon as it is plugged in, the components become dangerous to handle. The neon bulb is a mean a discharge the capacitor so that the circuit doesn't zap you if you go to touch/modify it. Another way to put that is: when you plug the strobe light in, don't turn it on at all, then unplug it, the neon light will go on to eliminate any build-up of charge. Give me an e-mail if you have any questions.
|I remember building this circuit as a kid way back in the 70's when all the parts were available from radio shack. The neon bulb acts as a trigger for the transistor and coil. It passes no current until there is enough charge in the capacitors and then all of a sudden it fires. It needs to be there.
