For those that want to watch some really cool stuff, weberauto has a real extensive library of videos. The teacher is most impressive. Especially when you see him doing this in a wheelchair. Hats off to you Mr Kelly.
Here is a link to that, he explains stuff real good. One of his last videos was of a mach e battery pack. Very useful.
Our school bought rights to these videos and they are available for french speaking ppl. But since everybody here is english, I wont go into that,
