Infrared footpad experiment
-
@lia I just tried a powerful led flashlight about 2cm away from the infrared module and it didn't affect the sensor, maybe full spectrum sunlight may, I have to test it when we get some sun.
Certainly mud or snow will affect it, I'm going to make a mount, source a relay today and test as a single zone as I only have one of the sensors for now, super cheap on Aliexpress. -
@lemur I hope it works out!
-
@lia The infrared footpad sensor exceeded all my expectations!
I set it up as an one zone, goofy foot sensor. Heel lift, hop off and quick stop worked flawlessly, all in bright sunlight too.
I can see snow, mud or other debris will create a ghosting problem, so I'm trying to engineer some kind of fail safe .
-
@lemur Amazing work!
I'm so happy it worked out fine. Any thoughts so far on how to stop those? Maybe a hydrophobic layer on the sensor or something. -
@lia Maybe I can figure out how to wire two in series so both have to be activated to turn on the footpad, if one is obsured (activated) , the other is deactivated the circuit will be broken.
Not a 100% solution, but a redundant system, side by side sensors.
Or tiny windscreen wipers. Hahaha -
@lemur lol
-
@lemur Figured out a getto solution to keep the sensor clean. Haha

@Lemur it's awesome how your experiment progression (or part of what has been shared publicly) is step ahead of Tech-Rails idea.
Outstanding video footage on FB 'DIY Squad' group! Guessing with such heel proximity no hard debris does not accumulate on sensor sight. Mud & moisture do leave some hesitations. I'll be following with excitement on your fail safe ideas on that experiment.

@sirgu I have a few ideas that need tweaking.
What I realized that this sensor system is super cheap and works for deep concave footpads like the Kush where a stick on pressure sensor has problems.
A friend is going to help me design and print a fender or half fender to incorporate this type of sensor.
FYI, I won't be selling any kits as liability is too high, I will post the whole procedure for those that want to diy after more testing. -

This is evidently understood. Likewise all of your one-off projects.
It is still admirable that you share all this know-hows and experiences. -
@Lemur that's so cool!
