James HobsonWait a second -- how are we going to control this thing? While a simple ON/OFF switch sufficed for the electric scooters, we don't think it'll work so well with a car...
We picked up an Alltrax 450A 72V golf cart off eBay for a few hundred dollars -- It also has serial output so we can monitor everything digitally!
We hooked up the laptop for some initial testing.
The speed controller accepts a plain old potentiometer as the speed control input -- so we 3D printed our own accelerator pedal to be attached to the existing gas pedal. It works surprisingly well!
Throw some batteries in the trunk with the chargers...
Some more in the passenger seat... Oh wait we took that out.
Charging it up... and off we go! Check out the first test drive video (linked in the main project page).
