We found this circuit in a 1997 documentation. It can be used in any common 12 V source and has two relays that disconnect the source in the event of a short circuit.
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...
