BIKE FLASHER

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 4.5V

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

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

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

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
