Well, Just got a Jazzy Pride wheelchair. It has three wires going to a plug that is for the power and on/off switch.
I also have a din jack that goes to the joystick. There is also a potentiometer in the circuit to control the speed.
I have seen where I can hook the motors up and run them full blast, but is there a way to hook up to the joystick that is in the wheelchair and cut the wires going to the pins of the joystick and hook them to the EZB?
Will I require a Saber-tooth H-Bridge?
Will i also require a 25A regulator?
I have zero left in my budget.
thanks,
Mel

I'd suggest saving for the saber-tooth though as it's a much more practical way to go.
budgets suck. if money were no object there would be some pretty insane robots roaming about.

thanks for your help.
If you want your DC motor to run at full speed and strength you need to give it the max voltage it's rated for. You can run them at lover voltages but they will be slower and weaker.
Hope this helps.
To answer your question directly, I am certain that you cannot hook the joystick wires directly to the EZ-B. I have the Jet 3 myself, I am not too familiar with the Jazzy, but no one who has tried to hack a wheelchair in that way has been successful. If your budget does not allow for buying more parts, you might consider the shortcut of using servos to mechanically manipulate your joystick. Check out Bravia's post #24 on this page.
Also, here is a link to download the manual for your wheelchair if you do not have it.
and Thank You Danger!
This is all you need...
1 x EZB board
1 x Sabertooth motor controller (of adequate power output for the motors)
1 x battery (SLA probably) or more for extra power
There are several videos out there, but this one shows it pretty well.
Thanks
