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. Summary of circuit features * Brief description of operation: Flashing light at adjustable speed * Circuit protection: No special protection circuits used * Circuit complexity: Few modifications to an existing circuit * Circuit performance: Works quite well * Availability of components: The problem is to find a suitalble camera flas unit to take components * Design testing: The orginal flash unit was modified until it worked as I want * Applications: Gain attention in parties, very small scale stroboscope experiments * Power supply : two 1.5V AA size batteries * Estimated component cost: Few dollars + old camera flas unit * Safety considerations: Electrical shock hazard, main capacitor has 500V charge and the trigger pulse is 4 kV, should be built to a well insulating case How does a strobe light work? A strobe light passes a brief, intense pulse of electric current through a gas, which then emits a brilliant burst of light. The gas is usually one of two inert gases, xenon or krypton, that emit relatively white light when they're struck by the fast moving electrons in the electric current. Because krypton and xenon atoms have a great many electrons and their electronic structures are very complicated, they emit light over a broad range of wavelengths. Thus the strobe emits a rich, white light during the moments while current is passing through the gas. Supplying the enormous current needed to maintain the brief arc in the strobe's gas is done with the help of a capacitor. A high voltage power supply pumps charge to the cpacitor (usually to 200-600V range). You can often hear a whistling sound as this power supply does its work. The capacitor plates are connected to one another through the gas-filled flashlamp that will eventually produce the light. However, current can't pass through the gas in the flashlamp until some electric charges are injected into the gas. These initial charges are usually produced by a high voltage pulse applied to a wire that wraps around the middle of the flashlamp or to the metal reflector near the flashlamp. A cascade of collisions quickly leads to a violent arc of charged particles flowing through the flashlamp and colliding with the gas atoms. The flashlamp emits its brilliant burst of light that terminates only when the capacitor's separated electric charges and stored energy are exhausted. The circuit I build this mini strobosocope using compotents mostly taken from an old pocket camera flash unit and some cheap components I already had. On the picture below you can see the picture of the flash unit I used in my circuit (quite similar camera flash unit then can be bought from American Science & Surplus): Picture of commercial flash unit CAUTION - high voltage of camera flash unit can caus
