I have an idea for a contest.  Recycle that old MINDA or PINDA Probe.  What ideas do you have for use of that old probe?

I was hoping to recycle mine into a filament sensor, FINDA style:

@chillypenguin

Do you have a wiring diagram and STLs for that?

I see that is from MMU2 assembly:

Does anyone think this could be used as a raspberry pi filament sensor?

I don't see why not. Does Octoprint support filament sensors connected via GPIO?

Maybe Prusa could sell the MMU2S without FINDA for a small discount and let you use the old PINDA that way?

As I put the just-removed MINDA into the SuperPINDA's baggie I had this thought too, good idea.

I haven't looked at it at all, does the MINDA return a simple open/closed signal, or an analog value (which then has some threshold to act like a switch) as the sensed object gets closer?
