Yea, this is pretty good stuff, and Paul -- the guy driving most of it... ah-hem, sorry -- seems to be a nice guy. He is a teacher (maybe elementary school?) who decided to get into EV's and made amazing progress, along with some help from the EV community. (you might have seen posts on EVDL and EVTech)
There is also an on-going thread (a lot to read, but informative and funny at times) and Paul's hardware page if you are interested.
http://ecomodder.com/forum/showthread.php/paul-sabrinas-cheap-diy-144v-motor-controller-6404-427.htmlhttp://www.paulandsabrinasevstuff.com/store/page3.htmlI am intending to make one of these controllers, after my two Curtis controllers let out the magic smoke. I have not had time to do it yet, also they were switching out to new power components the last time I checked in. I think I'll see how that plays out before buying the components.
Do I hear a local "Revolt" group build?
