Hi Lloyd,

Hey no problem sharing info, one of the easiest methods is to just operate the power chair joystick directly with two servo's.

The big issue with the chair electronics is that unless you are a licensed/registered wheel tech technician you cannot get any info or schematics etc from the manufacturer, believe me I know, I've tried, they covet their industry info. Pick a wheelchair manufacturer and try and get info on the inner workings of their electronics.

Even the programming cable I have has proprietor electronics built inside, very hard to figure out from scratch.

Hi all,

Great posts. I will be following this thread for my next project. Alan I am in Northern Virginia. Small world. I too am into the technical arts. My hobby has been Home Automation. I have been doing that for over 10 years. EZ B has introduced another hobby. I plan on integrating my projects into my existing Home Automation system. Like you my work comes first along with family. Looking forward to more posts!

Kevin,

I also did Home Automation for many years (Primarily with Homeseer software). Unfortunatly, with X10 I could never get the reliability high enough for an acceptable WAF (Wife Acceptance Factor) and without high WAF I could not spend the money for Insteon or other more reliable tech. Catch 22. At this point I have deactivated my Homeseer machine and shut down all the automation except in my home office where I do a little automation for security.

I can see the EZ-B as a great digital IO device at a fraction of the cost of other solutions, so after I build my Bot, I may take a stab at doing some more home automation too.

Alan

Thank you all for your input. I am going to try the sabertooth 2x25 controller and wider motors. I'll let you know how it turns out.

HEY PUTT PUTT, use a sabertooth 2x25 motor controller. i almost have mine set up to use with the ez-b. i actually already have the electric wheelchair remote controlled using a spektrum dx5e. view my youtube videos.

my two youtube id's are smartstuff2buy and robots4sale so check out all my inventions.

the problem i'm having is when i take off my receiver from my sabertooth motor controller, the ez-b is not talking to my motor controller. i'm using the modified servo movement panel, since it shows a stop, up, down, left and right button. its made for a continuous servo. the wheelchair is powered by 2 motors and its like a zero turn mower.

DO NOT use servos to control the joystick. thats more of the old school analog approach.

i know i dont have this 100% working, but i did the hard part of making the rc controller work, but i'm sure i'm missing something simple here.

guys, please help me find out why my ez b is not sending signal, or why the signal is not working for my sabertooth. i left the sabertooth set on r/c mode. i tried with and without grounding the sabertooth to the ez-b.

[email protected] whoever fixes this problem will receive $5 on paypal, if i can narrow it down to 1 person that finds the ultimate problem!

Yes I have been looking at the Sabre-Tooths...

I haven't been playing around with the EZ-B enough yet but your radio is inputting a PWM signal to the Sabre Tooth so your EZ-B has to do the same, I think that the modified servo panel is outputting an on or off state, try a vertical or horizontal servo output hooked to your sabretooth and see what it does, set the servo to 35 which should be center/neutral , leave your sabretooth set to RC.

Not sure if that will work but worth a try.

I have to get to work on this chair controller, I'm thinking that they may output some kind of single wire I2C, need to do more probing yet.

Dave

ok thanks dave, [email protected] is my email if you want to see more of my r/c wheelchair videos. i made an r/c lawnmower by pulling a push mower. later i will make it all one unit so its not pulling it. trying to make it "smart" with ez-b. good luck and i will try your suggestion tomorrow TJ

The modified servo Movement Panel has the ability to select the positioning for fussy motor controllers.

press the Config button on the modified servo Movement Panel and move the positioning to values that will work. There is someone on here who is using the sabertooth without issues after adding that feature. Wish i could remember who
