Hi,

the video shows testing of a speedometer with a selfmade electronics. It explains a lot about the function of electronic VDO speedometers:



The video has a German soundtrack, but English subtitles are available. If you don't see them by default, watch the video directly at YouTube and press the subtitle button below the frame.

Enjoy it,

Thanks for the link. This took me back to my days at university

Now I'm tempted to check the calibration on my car's speedo.

The next question is how to calibrate the speedo beyond re-orienting the needle on its axle.
