This circuit enables the on/off times of a 555 timer to be independently varied over a wide range. This is not possible with a conventional 555 circuit with the RC network being charged from the ...

This 12V power inverter circuit can be used to power small power devices that need a 240 volts. It is very useful when you want to use a 240 volts consumer powered by a 12 volts car battery .In ...

Sometimes the best inspiration is limitation. The 555 timer does “one thing” — compares a voltage to a couple thresholds and outputs a signal accordingly. It’s two comparators, a voltage ladder, and a ...
