This monostable circuit, from a 1977 Radio Shack documentation, uses a 7400. The time is given by the capacitor and the power must be supplied with 5 V.
Two sensors are used in this simple remote-control circuit, one to switch on and one to switch off the...
Using old germanium transistors like the CK722, this circuit has good gain. We found it in a...
We found this configuration in a 1974 publication. Transistors can be replaced with equivalents such as...
