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 configuration was found in a 1976 publication. The outputs of the logic circuits are applied to...
With this circuit it is possible to measure frequencies up to about 500 kHz using a common...
The very high-input impedance of the CMOS gate allows this kind of device to be used as a...
