This very low current circuit with the ICM7860 was found in the April 1995 Electronics Now magazine. The output voltage depends on the input voltage.
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...
