I'd rather wait to do a build page until both projects are finished so the chaor will have proper covers.

I don't know what type of solder they used but it refused to turn loose or flow into any desoldering wick. I haven't soldered a new one in yet. I will when the opportunity and an assistant is near.
Williamclark77 wrote:Thank you for responding Goose. I was hoping you would. I know your soldering abilities are light years better than mine. I attempted adding more good ole 60/40 or 63/37 solder. Albeit not much. I was afraid of connecting two pin holes and not being able to remove it. Even buried under flux it still never really flowed. I was also too chicken to turn my iron up over 375 degrees C and hold it on more than about 2 seconds.

I would more-or-less willingly pay their extreme prices IF I could get one with both encoder and (manually releasable) brake, but at least a couple years ago they said no can do. After all, I paid just as much for the MicroMotor units currently on Rachi's chair and though they are good, they're not nearly as good. There are some Chinese brushless out there that can be had cheaply, including with brakes and gearcase release (instead of brake release) but their right angle drives use worm gears and I hate to give up the efficiency of planetary+helical. Still working on my lift & tilt idea (now with lead screws), so it will be a while till I try to design a complete chair, so maybe other options will become available.
Another mfr of high efficiency brushless motors said they could mount encoder + brake available, but the only releasable brake they had had a bail that flipped over where the encoder would mount. When I get to the point of actually starting on a scratch built chair, I'll keep your offer in mind. 'Twould be even neater if instead of an encoder one could mount an absolute angle resolver.I'm positive I could incorporate a brake and encoder. It would be fairly easy for me to make an adapter to mount the encoder on the releasable brake with a small shaft extension if the small rear shaft wasn't long enough. I wouldn't mind doing it if you ever decide to.
No choice in the matter here. Siena area is full of steep hills, 10% grade or more, and driving as attendant I can't exactly keep my hand on the stick to keep it from sliding. However, couldn't you turn your motors at an angle - front end up to get more room? Yes, it would mean different mounts, but that seems to be the sort of thing you have 0 trouble doing.I ALMOST did on this one. The main reason I didn't is because that would make the motors about 1.5" longer. See the photo I just posted for Vitolds in the Roboteq thread (which doesn't show the docking pins either). I'm out of room without moving the COG farther forwards by moving the rear axle centerline rearwards. W1 nor W2 has mechanical brakes. I don't really miss them 99.9% of the time.

Anybody is welcome to help write the Arduino sketch. I'd compensate you. It's not that complicated if you know what you're doing. Unfortunately, I do not know what I'm doing!

You're killing me. The gifted Asian and abacus won't fit!

The display info is (or supposed to be rather): top middle - battery voltage, just below that - AH used, just below that - MPH, the small number on bottom - total mileage, just above it - trip mileage. The lights and horn text are latched and momentary buttons. That was simple to do. The speed and accel sliders are PWM outputs .1 to 4.9v to replace mechanical potentiometers. Haven't gotten to them yet. Need to let my brain quit smoking.
