The transistors in this circuit can be the BC548 and it also functions as a logic function. The supply voltage depends on the circuit to be excited.
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...
