This circuit implements a 3-way control, with outputs in A, B and C, using CMOS integrated circuits. I found this circuit in an old publication from 1978.
This high-gain circuit uses junction FETs (JFETs) and must be powered by somewhat high voltages. The...
This circuit counts 1 per second, displaying the value in binary. The circuit is TTL and must be...
Critical components of this project are the Geiger tube and the 300V battery. The battery can be...
