Hello,
Firstly:
I am new to this forum and this is my first post, it is by my experience generally on forums such as theese, a bad idea to come with a huge question/problem right off the bat, but here goes. Also as i'm more than a little interesten in this subject I will most likely at the very least be an avid lurker on this forum until i actually know what i'm talking about and then i'll most likely end up posting comments/suggestions etc in other threads.
But enough about that, and more about my project.
You see, a few years ago, I was given a really old electric weelchair. It was all fun and games until it broke down and i didnt have room to store it. (later found out it was a broken electromagnet for the brakes) So i dismantled the thing, took care of the motors and electronics and gave away the frame to my nephew so that he could make a gravity racer.
Eitherway, i've always planned to actually use the motors for something else, something that i could control remotely with my rc transmitter, or via wifi and an arduino.
So i'm stuck with three options:
i can buy an appropriate speed controller for the motors that gives me serial or pwm control over the motors; which is expensive and not all that challenging.
I can assemble the complete electronics for the wheelchair and try to make it work; which is pretty much like option one but minus the expensive part and add bulky and ugly
I can actually try to learn something about a subject i'm interested in and somehow "reverse engineer"/repurpose the circuit boards of the wheelchair, making it more compact; which is what i hope to be able to do.
I really dont know enough about electronics to know where to start exactly. There are two boards on this thing; one mainboard and what i guess is some sort of speed controller. And a set of contactors.
What my intentions are, is to remove the mainboard completely; or if need be, scavenge some components from it to make it work with the suspected speed controller and an arduino. And for this i need at the very least some input and help.
Contacted the maker of this wheelchair, and since ancient they didnt have much information on it, but they did have a flow-chart.
So i made an album containing pictures of the two boards, the small one is the "power unit" or speed controller, and the large one is the mainboard by my guess.
Album url is:http://img.im/a/h1p3sl
So if anyone have any suggestions on how to attack this problem, or any "do this, this and that to make it work like you think it should"-comments i would be gratefull either way. Any comments on this project task is greatly appreciated.
Regards,
remorsan
