BIKE FLASHER – Amazing! This bike flasher uses a single transistor to flash two white LEDs from a single cell. And it has no core for the transformer – just AIR! All Joule Thief circuits you have seen, use a ferrite rod or toroid (doughnut)


BIKE FLASHER This circuit will flash a white LED (or 2,3 4 LEDs in parallel) at 2.7Hz, suitable for the rear light on a bike.   Source: http://www.talkingelectronics.com


12v RELAY ON 6V SUPPLY This circuit allows a 12v relay to operate on a 6v or 9v supply. Most 12v relays need about 12v to “pull-in” but will “hold” on about 6v. The 220u charges via the 2k2 and bottom diode. When an input


3v WHITE LED FLASHER This will flash a white LED, on 3v supply and produce a very bright flash. The circuit produces a voltage higher than 5v if the LED is not in circuit but the LED limits the voltage to its characteristic voltage of


1.5V LED FLASHER This will flash a LED, using a single 1.5v cell. It may even flash a white LED even though this type of LED needs about 3.2v to 3.6v for operation. The circuit takes about 2mA but produces a very bright flash. My
