3 Led Voltmeter

[Gerben]

Hi Guys,

A while ago someone posted this 3 led voltmeter.
The more I thouht about it, the better the idea seems. Hook up warning buzzer to the red led and I'll know when to shut off stereo.

Just can't find it anymore. Please help.

Thanks and greetings,
Gerben

A little more complex but not too bad.
