Despite being found in a 1980 publication, this circuit uses components that can still be found easily. The circuit feeds an array of LEDs that run randomly, stopping at one.
This simple circuit causes an LED to flash at times whose active cycle is determined by C1 and C2....
This circuit is temperature stabilized. Modern equivalent transistors can be used, and the power...
This simple circuit works at the same time as a radio receiver and transceiver for the medium wave...
