The non-linear ebrake handles would indeed work that way. But if I understand correctly, the linear ones are supposed to allow you to brake a little or a lot, just like your regular mechanical brakes. That means they must be putting out an analog signal, rather than just full off / full on.
Whether or not the signal is the right level (or polarity) to use for a throttle has yet to be determined. I'm sick enough at the moment I can only wobble to the bathroom and back here to the bed, but once I feel well enough to work on stuff without falling on it, breaking it or blowing it up, I'll test out the idea.
Polarity is easy to fix, by flipping the magnet around the other way, I think. Level might have to have op-amp scaling and offset. (well, transistors could be used instead).
One thing I got to thinking, related to waterproofing a throttle, was putting the throttle in a box, waterproofed more or less, and using a cable throttle from a motorcycle to activate the sealed up regular throttle. It could be a trigger throttle from a weedeater, a brake handle, a shifter, anything that pulls on a cable.
That's pretty much how my original plan for my pedal-chain-tension-operated throttle would have been, with the Honda scooter cable-twist-throttle setup to pull it's lever up for an override when I didn't want to or couldn't pedal. I never have been able to build it to test the theory yet, though. Originally the box would've been a pot throttle with a lever on the outside that had a roller on top of the chain, and inside the box the pot throttle and the electronics needed to offset and scale it's output so it could be adjusted to suit the pedalling tension vs motor speed I wanted out of the system at a certain pedalling force. Plus some op-amp integration to smooth out downstroke vs rest of rotation, so it didn't get power surges.
