Found in an American documentation from the 90's, this circuit aims to light a neon lamp with voltages from 5 to 15 V. It is a small inverter that operates close to 15 kHz.
This circuit uses a common multimeter on the voltage scale to measure the beta gain of a...
Only signals about 1 kHz can pass through this tuned circuit. The main component is a operational...
We found this circuit in a Hands-On Electronics from the 90s. The circuit must be connected to an...
