segway i180 grip

Hi,
Does any one knows how the grip works? (for i180)
Is it Potentiometer?
if yes what are the values?
Does any one try to put something instead the Original grip
Thanks,
R

It's based on magnets located on the turning part of the twist grip. The stationary part of the handlebar contains a sensor that is reported down a wire to the control board inside the handlebar.

Is this digital communication?
Serial communication
What kind of signal is it,
Did someone ever took a scope here to check it?

If yes- I can build some Arduino board to overcome this

Thanks,

Hi

From memory;

There are Hall sensors within the handlebar ( that are not readily visible ).

There is a pair of magnets ( small short rod/cylinder style ) in/on the twist grip.

Thus there's a weatherproof link.

Error conditions include:
1 A magnet is missing.
2 A magnet is installed in the wrong orientation.
3 Both magnets are installed in the wrong orientation.

Hi,
Does any one knows how to disassembly the top handle of i180 - in order to get to electronics - LCD display, I couldn't find any screw?
it seems like one part - however in broken parts I see that this is from 2 parts ?

Also found out that what I missing is only Magnet, all the handle right/left electronics is inside the handle

Thanks,
R
