I don't have a good way of posting the schematic in picture form. It's too dang big. any suggestions?! my crap software won't allow it to be saved as a pdf.
you could upload it to http://picasaweb.google.com or some of the photo sharing sites. Alternately you can email it to me and i'll host it for you.

edit: yes you're right the Aussies have a revision 2D of the design... however the link to it is broken.

Question My brother, the electrotech

Hi everyone, I beg your pardon for not having read the whole 300+ pages of this important thread but the topic got me very excited. I wanted to know if there is a final revision of a DIY motor controller Schematic or is it still in beta testing? I think I could use my brother into making it and that would be the beginning of my future EV.

The revision 2c schematic works well, but you should use the component values listed in the bill of materials on the wiki. A couple resistor values have changed (R15 and R16).

And this is good for let's say a 110 V AC motor or do I need to search for specific motor? I'm a beginner into this but I think I can manage the info I'll be given.

Well, this controller is for a series wound DC motor. It can use anywhere from 0v up to about 144v. If you change the mosfets/diodes/capacitors on the power section, you can have the voltage range go up just about as high as you want.

Hi Mike and Adam, I'm getting oh so close. If only there weren't so many interruptions. I'm teaching my daughter to drive, and she's looking for a job. Meaning that I have to ride with while she goes around applying. Then I got a ticket for a headlight out and after 2 days of driving around well over 40 miles, I'm getting closer to the end of that..... then having to work for a living.... oops I digress..

Controller: power on LED's on steady, Realterm up and connected to the com port I have no communication and cannot see program. WH-@#$@%!!!

Sorry to bother you again.....

The controller is coming along very nicely and I wouldn't change anything. I rather build my own controller and know everything about it than fork out tons of $$$$ again for something that I can't fix.

Thanks guys for all your hard work.

Do you have the serial port plugged into the computer? Is com1 or whatever being used by another program?
