Caveman optical sensor RC controller concept.

[gwhy!]

Bump.

Has anyone pursued this optical sensor-controller to get a working model yet?

Or, does someone have an ETA when this might happen for RC motors?

TIA

I think this idea sort of went away, it was talked about before anyone really had a working hall sensor setup working well on rc motors using standard sensored speed controllers.

Its a cute idea, but optical always tends to fall over in implementation - it was tried with very limited success in automotive applications, for stuff like crank angle sensors etc. but as soon as crap falls into it - it falls over. The majority of stuff is hall effect for good reason. The 'cave man approach' is nice, but you could do the logic with something as simple as gates or heaven forbid something as primitive as a GAL.

The heat effects on LED's - visible or infra-red are also well known. If heat is that much of an issue, then perhaps pickup coils are more appropriate.
