We found this circuit in documentation from the 90s. Instead of a voltmeter, you can use the voltage scale of a multimeter. The circuit tests batteries under load.
This field strength meter is intended for the VHF range, above 100MHz. The lowest voltage or...
We show an oscillator that produces rectangular TTL signals based on inverters. Inverters can also be...
The circuit presented, from 2006, serves to control loads at a distance, robots, etc. It can be...
