Found in old documentation as permanent security lighting, this circuit uses common components. The lamps can be replaced by fluorescent inverters or LEDs with appropriate series resistors.
This astable multivibrator configuration causes two LEDs to alternately flash at a frequency...
In the figure we show our first circuit that consists of a simple touch switch capable of driving a...
This electromyography monitor is from a 1978 publication on operational amplifiers. The components are...
