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

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.
