That sounds interesting, instead of pots

Marc…

sounds spiky

I have a wah pedal for my guitar rig that is optically coupled…has never once spiked on me - it doesn’t use an LED emitter/detector but a simple photo detector; I think the emitter/detector is a better way to go for this case (lots of chat over on VP about using this sort of thing to detect zero crossing in building instruments with x.27 steppers). You do have to take some care with the light paths in the setup (I think I’d use some fibre optic cable), but it’s a perfectly sound mechanism.

I have the same, the morley wha-volume pedal. It uses a slighly different approach. There is a led in a fixed position that point to the receiver. Moving the pedal will make a mask to move that blocks some light. Nice piece of hardware

sounds much less spiky

Yes it s called electro-optical circuit. Nice, easy and no wear at all

Yes - that was the first one I bought, back in thee 70s. I’ve since bought two more - wah/volume, and a wah/volume/distortion, which I like very much!

Ms sidewinder stick (old) used optical sensors

Jeez, back to the future… , MS Sidwinder Pro was when 1999/2000?
…and … my God, I have this Genius stick from video still in attic closet somewhere… spiky pots as hell.(100k) … same year or so.
Considering Falcon is '98 … hehe … same turf.
… maybe I would even bother to convert the Genius to the LEDs … have to think, but is it worth it… only 4 buttons. would use it for what exactly?? …
and resolution is what 128 ? … compared to today’s best 1024 … well…
I would rather chop off its usb controller and use those buttons and axis for … dunno… Mixer for Traktor (hehe:headb:)\…btw , there is a guy in Opentrack github who used webcam as WW1 flightstick joystick … put ps3cam upwards and on the end (bottom) of the stick is IRLed , so easy X/Y

Hello, everyone!
A must read!

I seem to recall that this stick was/is optically coupled too -

I have one of these laying about some place…one of the first sticks available for the Mac, as I recall. Now where’s my ADB to USB adapter?..dat’s way-back there!

I think using two pieces of polarizer film would give a more linear result. The LED, LDR and one polarizer being stationary, the second polarizer rotating
-
I think you mean a columnator…or both…
-
Rotating polarizers block light based on angle. If the sensor detected intensity it would vary. http://www.arpnjournals.org/jeas/research_papers/rp_2015/jeas_1215_3186.pdf I just don’t know if it’s any good for a joystick application.

Correct. When poth films are at the same angle you have maximum light transmition, when at 90° you have minimum
