Can this Cheap LEGO RPM meter be used on FRC Bots??

[NoodleKnight]

is it the revolution sensor that comes in mindstorm kits? If so, i'd think the thing would fall apart at high RPM's, lego motors don't spin very fast. I have no clue how to adapt one into counting RPM's for a non-lego device... maybe some epoxy and duct tape.

The duct tape would thus make it an illegal device.

Electrical tape.

El,
This is not the rotation sensor that comes in Mindstorm kits, but it does look cool and the price is right for an experimental device. I think the picture may be misleading as to size. The description makes it sound like a handheld computer to measure rotation and calculate distance traveled or RPM. Looks cool though.

Looking at the link it isn't one of the blue rotation/revolution sensors that comes in the Lego Mindstorm Kit.
I never actually played with this device or had it in my hands but what I think it is a portable device that you can just put over a wheel shaft and it gives a reading just so people can know how fast their personal creation goes :-)
My guess is that it could be used on counting rpm on a shaft that the exact same same size as the + Lego shaft. Also, probably not accurate enough for our type of application.
For us measuring RPM we use something like THIS.
