Elevation system

Installed new elevation system and inclinometer with pot (pictures here)

I choose an analog readout, the panel meter is recovered from an old ZetaGi wattmeter and the scale redrawed with the software “Galva” by F5BU.

The panel meter is driven by a simple circuit, an op-amp LM324 (2xbuffer + current source) with input the potentiometer, part of a Wheatstone bridge. Thanks to IZ8DWF Frank for some tips.

This video is intentionally speeded up through the boring parts.
