Hi Guys-
Looks like one of my slide pots is going out and am toying with the idea of using string potentiometers. Anyone used one?
Thanks,
Matt

Matt, there's been discussion here regarding string pots and where to buy them. Even how to make them :)
Keep lighting the world Matt, you do a good job of it :) :) :)

Matt here is a short thread on mine;http://www.mycockpit.org/forums/show...ght=string+pot And Gallie (Mike) also built a set. I think John Combs has a commercial set.
Here is my poor man version of a string potentiometer. Not really how a string potentiometer functions since real ones use transducers, but worked quite well in my setup.

Thanks for the info guys. The thing I've found in my 737 quadrant is due to the movement of the arm, the travel is not linear at the end, ie the rate of change decreases towards the end of throw of the throttle arm. A string pot would fix it, but MAN those are expensive. I'm very torn about it :-).
Rodney-
There are no such thing as stupid questions and that's actually a very astute one! Yes they are linear but thanks for the reply!
Matt
Actually, it wasn't Rodney who asked the 'stupid' question :-). It was me, but what I actually meant is whether you checked with an ohmmeter whether the pot is actually linear. I once ordered & received some 'linear' pots which turned out to be audio taper instead, so the only sure way to know is to check them yourself. Just a long shot ;)

It looks linear, it's just very dirty/jumpy and i wouldn't mind changing them out (pulled the quadrant out anyway). The thing has been in there almost 10 years now. Does anyone have a good lead on 100mm linear pots? Seems everywhere I look they are audio taper.
Thanks!
Matt
