We found this circuit in a 1977 Timers Cookbook. The circuit uses common components to divide a 1 kHz signal by 2. The output has an amplitude of 2 Vpp.
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...
