This game was found in Radio Electronics from the 90s. The components used are common except some that are from that time and that can no longer be found easily.
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...
