VW Beta 4 radio

23 Jan 2012 180
We've had a few cold days and my car wouldn't start anymore. It did a few 'wup wup wup-s' and that was it. Today I tracked down my radio to be the culprit. When I measured it today I determined it to have a standby consumption of 1.44W (120mA). And that sucks the battery dry in about 10 days. Something must have broken, as it didn't do that before. I couldn't find any obvious things like blown caps. The main amplifier gets a bit warm without any load attached and there is absolutely no signal reception anymore... DOH!

It's an old radio

They don't make chips anymore. And Austria... I'm shocked.

It's an old radio

Passive frequency... whatever

Strange dots

Analog hell

Gets warm

Tuner input

All of it

I like these multi-function potentiometers. Maybe I will save them from getting recycled too soon.

Lot's of TDAs on there

Machine translation - sort of

"... chronic common LED jockey fragments ..." "... demo cipher ..." - NO NO NO - I do add meaningful comments to my code. Almost as good as "This provides top to which!". And that came from a human being - as far as I know. The source of that one is a secret.

The new RGB LED Ring v2 is powerful enough indeed. Using the Arduino 'ShiftPWM' library (slightly adjusted) gives super-smooth fading effects.
