Re: [PSUBS-MAILIST] Rudder angle indicators

["Alan James" <alanjames@xtra.co.nz>]

Thanks Jens,
That looks good. I had saved some links to projects that I thought would 
help me build
an LED indicator display but I'm electronically challenged & so thankfull of 
some help.
Am thinking of other easy ways of building the magnetic potentiometer. I 
will post what I come
up with & see wether it's compatible with your project.
