Adjustable Strobe LightThis 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!

Notes
1. T1 and L1 are available from The Electronics Goldmine
2. 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.
3. Most any diodes rated at greater then 250 volts at 1 amp can be used instead
of the 1N4004's.
4. Do not operate this circuit at high flash rates for more than about 30 seconds
or else C1 and C2 will overheat and explode.
5. There is no on/off switch in the schematic, but you can of course add one.
