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!

Description
Substitutions
R11250 Ohm 10 Watt Resistor
R21500K Pot
R31680K 1/4 Watt Resistor
D1, D221N4004 Silicon Diode
C1, C2222 uF 350V Capacitor
C310.47uF 400 Volt Mylar Capacitor
T114KV Trigger Transformer (see "Notes")
L11Flash Tube (see "Notes")
L21Neon Bulb
Q11106 SCR
F11115V 1A Fuse
MISC1Case, Wire, Line Cord, Knob For R2

Notes

  1. T1 and L1 are available from The Electronics Goldmine (see Where To Get Parts).
  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.

I want to build me a Photographers studio flash heads. Do you perhaps know where I can find something like that? Do you perhaps have better, more cost effective ways of obtaining this or similar item? Thanx alot
