Firstly I will say that he made long ago (but still works), because some details I can pass up, not exact.
Battery-powered, has a tachometer with 2 limits: 6000 and 1500 speed, it is necessary to configure the appropriate trimmers (for example, feeding the input of the pulse generator).
Some parts of the circuit are taken from the Radio (for input circuits - just an idea), there you can find the data on the setting. In particular, the bottom painted the voltage Converter 400 In the electronic ignition circuit, the data trance unfortunately at hand now no, it's just I have such self-ignition and I stuck it ready.

The sensor is made so: cut the ferrite ring with a diameter of about 30-40mm winding on one half of with d0.1 homemade "object", which chart hung on the wire.
The strobe can be disabled.
The lamp itself with the details (the small box) is in the extension box, which we and Shine, brightness will depend on conder (4uF 400V). The ignition transformer is made on a ferrite rod 8mm length approx. 50mm (from antenna), winding... well primary I looked - 30 Vit d~0.3, secondary (to the ignition) 1000-wit. Remember what I thought in the parameters IFC, there is given the voltage of the ignition and we just need to take the ratio Vподжига/Wat, better to make a margin. Wound first high voltage, then duct tape, on top of the primary. In General, rude and simple ;-) Floor lamp glued foil for greater brightness.
The disadvantage of this: at high speeds (anywhere from 3000), the Converter does not time to charge conder and flash are ignored, but for settings such momentum is usually not needed. You can try to increase the power Converter (AFAIR reducing the resistor AA, it's better to look at resp, "Radio").
The advantage is that the flash is bright and can be configured with a rather strong light, well seen. I freely configured on a Sunny day in shadow, and in the garage at all possible in the corner of the hood to shove, and he shines like a small lamp.
If someone will remake another way to charge the capacitor for a flash, then it is necessary that the charging scheme allowed a short circuit in the load, because the charge of the capacitor is periodically discharged into the lamp. Oh, and don't overdo it with the power (it is possible to estimate even just on a heating lamp), or I'll die quickly.
