Hi you all! I designed a small led stroboscope light for testing crystal sync accuracy of movie cameras. It is a crystal stabilized strobo, very accurate flashing speed and can be powered with power supplies of from 8 volts to 26 volts (for example with a 9v battery) . These are supposed to be as affordable as possible so I decided to sell them without case to save about 50% on the assembling costs and because they can normally be used just as is. All the controls are possible to wire
