Bootstrapped Timer by Andrew R. Morris

Bootstrapped timer Circuit designed by Andrew R. Morris, all rights reserved.This circuit demonstrates how to use bootstrapping to seriously boost the output power of the timer. The LC555 can only put out about 50mA as it is. This circuit can put out at least 200mA and goes to the rail as well. The LM555 time puts out 300mA, but doesn't go all the way to the rail. Replace Q1 with a big MOSFET and you can put out big current with few components. Discovercircuits.com is your portal to free electro.......

555 Circuits II - Jose Pino's Projects and Tidbits.

This circuit can be used to activate a relay for two or three minutes. Pressing the switch the relay will be activated. Changing the 1M resistor with a variable resistor you can vary the time. The 0.01 capacitor is important because it prevents any false triggering. The circuit will work OK with 6 Volts without any modification. If you want to use 9 or 12 Volts, you need to change the relay with a 9V or 12V relay. Using this circuit with 120 VAC is not recommended, however, using the right parts.......
