Photoflash Capacitor Charger has Fast Efficient Charging & Low-Battery Drain - DN303 Design Notes__ Linear Technology/Analog Devices
Pocket stroboscope - This circuit is a minI storoscope which you can make so small that it can fit into your pocket. The circuit is not very powerful, but is works out of two small 1.5V batteries for an hour constantly and maximum flash rate. The flash rate is variable from zero to about 10 Hz. Quite nice small device to have with you in parties to gain attention __ Designed by Tomi Engdahl
Repetitive trigger - Based on the 555 timer IC , useful for strobe lights. A bit on the 4017 counter IC for multiple flashes and sequences of flashes __ Designed by Don Klipstein
Spare Flip-Flop Stretches WR Strobe for DSP - 07/20/95 EDN Design Ideas: A 74LS592 programmable counter (not available in high-speed F or ACT versions) is a convenient IC to use in DSP applications, such as in an ADSP-2101 design running at 10 MHz. However, a close inspection of the counter's worst-case timing specifications and the WR strobe width reveals that the 74LS592 fails Design by Dhananjay Gadre, IUCAA Instrumentation Lab, Pune, India
Strobe from Flash - After using a disposable camera, you can build a strobe light (flashing light) with one simple modification. (6/02/2006) __ Designed by Jose Pino
Strobe Light - A xenon flash tube is a triggered gas discharge device. A voltage may be impressed across the tube and it will not conduct until the xenon gas is ionised by an external high voltage (typically 3 to 5kV). Once triggered, the gas becomes a very low impedance, and discharges the storage capacitors in about 1ms (this varies considerably, but this figure is fine for basic calculations) __ Designed by Rod Elliott ESP
Strobe Light - 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 __ Designed by Aaron Cake
Strobe Light 12 Volt Coil Powered - This circuit will give provide a Good Strobe Effect for a variety of
Portable Uses. Nominal current draw is "up to about" 1 amp at 12 volts. Depending on value of capacitor on pin 2 of the 555 and the particular choke that is used. The .01 cap on pin 2 of the 555 may be slightly changed in value to optomize the output drive to the 22 mfd capacitor. __ Designed by G.L. Chemelec
Strobe Trigger - These pictures are scenes frozen by a flash unit that is triggered by the action being recorded. They were made by setting up a shot, opening the camera shutter using its "bulb" setting, and carrying out some action that opened or closed a circuit to trigger the flash. The balloon pictures were taken by triggering the flash when the balloon began to shrink after being popped. in most cases the balloon had a strip of foil attached to it with probes pressed against it on two sides, with a circuit interrupted when the foil pulled away from the probes __ Designed by John DuBois
Strobex Schematic - Schematic only for a Variable intensity Variable Speed Stroboscop, no circuit description given. __ Designed by Samuel M. Goldwasser
Strobo Control - Remote controller for professional lighting system stroboscope, controls the flashing speed. __ Designed by Tomi Engdahl
Strobo Disco Light using Standard Tube Lamp (TL) - Using a standard fluorescent tube lamp (TL) , you can make your own disco light, similar to a stroboscope light. You can even use a half-broken lamp, which one side of the heating filaments has broken. This circuit use only one side heating filament inside the tube. Look at the circuit’s schematic below.__
Stroboscope - The 220v supply is rectified and then used to charge the two 3µ* capacitors. The 1µ capacitor also charges (more slowly) through the 150k resistor and 1M variable resistor. When the voltage across the 1µ capacitor is high enough to cause the diacs to conduct, the thyristor is triggered. This produces a high voltage "pulse" at the secondary of the transformer. This pulse causes the tube to conduct and a flash of light is produced. __ Acknowledgements The stroboscope was taken from an excellent French electronics magazine sadly, no longer published called "Elex"
Stroboscope triggers - This circuit typically uses a voltage around 300 volts for the main high voltage supply and needs a low voltage supply of typically 6 to 15 volts. __ Designed by Don Klipstein
Switching Supply 12 Volt Strobe - A HiGH POWER STROBE, suitable for many applications. __ Designed by G.L. Chemelec
Transmitter for Line Powered Xenon Flash - This line powered xenon flash circuit drives a small camera type flash tube. it has an optical isolator to allow the flash to be safely triggered from some remote device. A flash rate of 2Hz is possible with the circuit . . . Hobby Circuit designed by David Johnson P.E.-June, 2000
Trigger for Strobes - This page contains some information on circuits which can be used for triggering stroboscopes from external circuits. The circuit here are designed to be integrate to strboscope circuits so that they can triggered using external trigger pulse. The standard trigger pulse used in professional stroboscope controllers is 3-10V pulse. if you don't already have a suitable controller, __ Designed by Tomi Engdahl
Triple Stroboscope - This circuit enables observation of movement between other stroboscopes. Generation of rectangular signal is based on NE555. This circuit requires a low power supply that is made from a simple transformer TR1, traditional rectifier bridge and zener diode. NE555 works in multivibrator mode generating astable pulses of 2Hz to 20Hz. The frequency is adjusted by potentiometer P1. The control potentiometer P1 can be placed as far as 30 meters away, for suspension of stroboscope’s work from far away. __ Contact IQ Technologies

Welch Scientific Model 2153C Stroboscope - Here is a schematic for a typical line operated variable rate stroboscope. This unit is from Welch Scientific - Model 2153C Stroboscope. These things typically gather dust in the dusty dark corners of high school physics labs. __ Designed by Don Klipstein
White LED Stroboscope with Constant Duty Cycle & Constant Current Drive - Finally, white LEDs are bright enough to use in a practical stroboscope. This circuit can operate as a bench-top stroboscope that, in conjunction with an oscilloscope or frequency meter and bench top power supply can accurately measure rotational speeds, or it can be operated hand-held from a single 9V battery, __ Designed by Dick Cappels

Xenon Photoflash Controller - This 9v battery powered circuit is designed for remote control flash needs. A charge control circuit turns off the high voltage generator when the photoflash capacitor is fully charged. A neon lamp is included to indicate when the system is ready to flash. . .
