Re: (ET) Something to ponder - modify a wheelchair controller?

Quoting JBR <reinharj frontiernet net>:


Hi Guys,
How hard would it be to modify a wheelchair (two 24vdc motors, with 
joystick)
for the higher current and voltage required for the motors large enough to
move an Elec-Trak?
Difficult to impossible. There is a good chance it would actually be easier to 
start from scratch.
Not only do you have to change the power components, there is a very good chance 
you would need more of them.  Also the driving circuitry would have to be
changed. The internal power supply (ies) would also need to be changed and any 
internal feedbacks modified to scale properly.

Theres even a reasonable chance the phyiscal layout wouldn't be adequate.

And that's just for starters.
