I'd like to fit the controller inside the seatpost which throws out anything commercial I've seen (asides from the external keyde square wave controller).

Does anyone have advice of where to find info on how to make a controller that uses torque input for PAS?

Thanks ahead, Shawn

When I was at the last Shanghai show, there was a company showing tint controllers. I took one of their brochures. I was looking at it at Xmas, but then I chucked it out.
Here's a photo. It's smaller than it looks in the photo. You could take out the PCB and use a strip heatsink rather than a box to make it even smaller:

Thanks. Something told me I'd hear from you, d8veh, you're all over the forums offering the technical help. I wonder if the unit would fit inside a 31mm ID seatpost when removed from the alloy shell.
