12 Volt Strobe Circuit: this circuit uses12V DC instead od mains AC. This is
very good idea if you don't want to mess with direct mains voltage connected circuit
or you want to run Strobe from batteries. (added 6/06) |

Circuit forms fast portable light pulser: 10/16/03 EDN Design Ideas /
(added 1/05) The absence of a fast one-shot multivibrator in the entire TTL
family, as well as the low-voltage swing and unwieldy supply requirements of ECL,
drove us to exploit the fast transition times and low propagation delays of F-series
gates. The application called for the implementation of a compact, portable, fast
light pulser for field testing fast photomultipliers in gamma-ray astronomy work.... |

Constant Brightness LED Stroboscope: for Measuring the Speed of Small Motors :
The rotary switch is available for $5.00USD as of 2003 from DigiKey under part number
EG1951-ND or EG1952-ND. It is a real pain to operate this circuit without a proper
switch. You can put multiple 4017 ring counters in series to reduce the duty cycle in
order to obtain a more focussed strobe image but you will have to increase LED current
to maintain the same level of brightness and that will shorten LED life.....

Emergency Strobe Flasher Generates 250V: 08/05/99 EDN-Design Ideas / (added
8/05) Figure 1 shows a complete circuit for an emergency lamp that operates from a 12V
automotive battery. The xenon flash tube requires a 250V-dc anode voltage and a 4-kV
trigger pulse. To generate the 250V dc, IC1, a switching regulator controller, and T1,
a standard Versa-PAC transformer, operate in the discontinuous-flyback mode. With this
configuration, circuit efficiency is typically 75 to 80%. R1 and IC1's
internal-sense-threshold voltage limit the.... |

Flash Slave Trigger: Flash slaves are used when you need to
supplement1-flash unit with1-or several more. This slave trigger simply triggers those
other units. It does this by "seeing" the first flash (using a phototransistor) and
triggering the other flashes a few microseconds later. The sensitivity of the circuit
is adjustable to compensate for ambient light or dimmer than usual master flashes.

Hacking the Kodak Max Single Flash Camera into a Self Repeating Strobe: this
approach is recommended mainly for homebrewing a strobe that is powered by a single1.5
volt battery. If you can use a higher supply voltage, there are better ways to do
this. (added 8/03) |

Strobe Light 12 Volt Coil Powered: (electronic circuit added 10/06) |
|
Strobe Light: 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 and causes the triac to turn on. This allows the trigger transformer
T1 to send a very High Voltage to the flash tube and lighting it. The flash timing is
adjusted by the flash freq. pot. (added 09/05) |
