Prepared for DC 20A motor speed control circuit (mk2) TL494 PWM control IC is used. Integrated IRF1405 N-channel MOSFET output transistors in the two units have the speed setting potentiometer 10k 100k if the frequency setting is adjusted with a 12-volt or 24-volt DC motor can be used. Speed control range TL494 0/100% idle current drawn from power max 20mA. 20 amps also connected to the supply source (battery, etc.). Voltage sensing feature, there is low ..

USB Powered Inductance Meter Circuit Atmega8
Coil measurement “Inductance Meter” circuit based on Atmega8 microcontroller LCD HD44780 driver and the system’s power supply is taken from the USB port on the computer or adapter operated with the circuit. Circuit of the box mints box cut and processed interesting metal, enamel paint made circuit optimized 🙂
The LCD screen of the circuit 10MHz frequency coil over strut value is displayed in the Information, as well as the frequency.
