I do say: Bra. Vo.
Also, I have voltage envy.
Also, we definitely spent too much money on project ForkenSwift.
Also also: did Paul really make an ammeter out of a calibrated chunk of something for a shunt and a multimeter to read millivolts? I knew it was doable, but I didn't take that path. Partly out of fear, and partly because I got a reasonable deal on the new-old-stock ammeter & shunt from Mr. E. Bay. (39.78 CAD, shipped.)

Well thank you! I'm not sure how far I would have gotten without your example. I think I pretty much had no choice going to 72v because of my tiny motor: running the amps required at 48v might melt it. I really and truly was going for 48v when I started though.
As far as the ForkenSwift budget, I just looked over the expenses: where do you think you could have trimmed the price?
Paul is a genius. I firmly believe that he can make a controller out of stone knives and bearskins. Post #245 on his thread is where he used his ammeter the first time.
