DIY HACK – Voltmeter Ammeter LCD
by max on Wednesday, February 21st, 2007
Check out voltmeter and ammeter LCD panel you can make using an Atmel8 MCU. Tight!
This multimeter was designed to measure output voltage and current in a PSU, where the current sense shunt resistor is connected in series with load at the negative voltage rail. It needs only one supply voltage that can be acquired from main PSU. An additional function of the multimeter is that it can control (switch on and off) an electric fan used to cool the main heatsink. The power threshold at which the fan switches on can be adjusted using One Touch Button Setup.

This is very interesting device and would like to build one of these for a remote power supply I am building.
