12 Volt Strobe -  Strobes are useful devices for seeing fast moving components freeze or just as lighting effects.  Unfortunately for a really good result you need to use a Xenon flash tube which can produce intense brief discharges of light but it needs high trigger voltages - upwards of 4KV!   __ Designed by Phil Townshend 2011

12 Volt Strobe, Coil Driven -  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

3 Xenon flashings found in flash for disposable cameras -  You are going to like this project.  it costs less than $3.00, contains six BUiLDiNG BLOCKS, re-cycles a disposable flash camera and you are going to learn a lot about electronics. 
Everyone has seen a disposable flash camera.   __ Contact Collin Mitchell

9v Powered 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. . .

A doozy requiring some parts you can't get at the 'Shack. -  You can make a doozy of a xenon strobe using the 12 volt DC in, DC output mercury lamp ballast here at http://www.  donklipstein.  com/ebdc12.  html.  You may run into a problem with the flashtube arcing continuously after a flash.  if you use an open-collector comparator such as a 339 in the overvoltage sensing section of this circuit, you can wired-AND the comparator output with some sort of scheme to disable the circuit for a few to a few tens of milliseconds after a flash (by "pulling down" Pin 5 of the 555).   __ Designed by Don Klipstein

A mad idea for a blacklight strobe -  CAUTION - May be both hard on your eyes and a bit disappointing __ Designed by Don Klipstein

A 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

Adjustable Strobe Light -  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!  __ Designed by Aaron Cake

Amplifier for a Xenon Lamp Flash Detector  -  This circuit has a very low standby current requirement yet has very high sensitivity toward the light flashes from a xenon lamp.  When connected to a flip/flop it can serve as an on on/off Controller. . . Circuit by David Johnson P.E.-February, 2002

Beat Tracking Strobe -  Strobe lights have always been an integral part of dance parties, adding an additional element of excitement to the festivities on hand.  The combination of flashing lights and music-especially those with a definitive strong beat- are a natural complement to one another, where the strobing of light is an extension and links one's aural perception to his visual senses.  The applications of strobe lights are numerous.  in more involved and comprehensive applications the strobe user would like the strobe to help fuse together the music and light.  For our final project we opted to attempt to create such a strobe system appropriate for the more complex application by creating a light strobe system that flashes a light source directly in sync with the music in real time __ Designed by Chris Chan and Kenneth Liu

DUAL- COLOUR STROBOSCOPE -  Stroboscope is a device used to make a cyclically moving object appear slow-moving or stationary.  This is realised by illuminating the object intermittently with short pulses of light.  Stroboscope is used in the study of insect flight.  it can also be used for experiments with simple pendulum, studying details of rapidly moving objects and strobo-animation.__ Designed by Raju Baddi

Emergency strobe flasher generates 250V -  08/05/99 EDN Design Ideas:  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, IC 1,  Design by Jose Luis Arce, Tecnosuma Havana, Cuba

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.   __ Designed by Aaron Cake

Flashing High Intensity LED 3rd Brake Light -  This circuit to make a flashing 3rd brake light assembly was designed to be easy to locate all the needed components and reasonably in expensive to build__ National Semiconductor

Flashing Indicators -  Need to flash "turn indicators" using a 555 and a single 20 amp relay.  Here is our suggestion.  The timing resistor needs to be selected for the appropriate flash-rate.  __ 555-Timer

Hacking the Kodak Max Single Use Flash Camera into a Self-Repeating Strobe -    NOTE - this approach is recommended mainly for Homebrewing a strobe that is powered by a single 1.5 volt battery.  if you can use a higher supply voltage, there are better ways to do this.   __ Designed by Don Klipstein
