Found in an EEE from 1970, this circuit supplies a voltage of 12 V DC x 10 mA current from the power grid. The NOR or NAND port used is TTL.
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...
