Chibikart uses two Turnigy SK3 5065 motors, driver sensorless by Jasontrollers. Its cheap and powerful, so I can dig it. But whats better than the grinding, powerful not-launch of a sensorless drive? The smooth, terrifying launch of a sensored one. Id been thinking about how to achieve this on a vehicle, especially after seeing TinyKart at NYC Maker Faire. And then I forgot.Charles recently posted about adding sensors to sensorless motors and driving them with Jasontrollers. And I realized that it was what I wanted to do, so I emailed him. And being the awesome guy he is (and a fellow lover of tiny brushless things), he emailed back, and I ended up with some sensors to put on a motor. I pulled the motor off TinyBike, popped the sensor ring on it, whipped up a quick mounting plate, and went off in search of a Jasontroller. Fortunately, I had one lying around. Unfortunately, I had cleaned up the wiring and modded the circuit board, meaning all the stuff I needed to hook up the sensors was gone. Dang. So I ordered another Jasontroller. And now I wait.
Which leaves me with two options. I can work on the frame and mechanics of ChipiKart, and have it ready to test come Jasontroller time, or I can daydream about designing my own controller. Knowing my project ADD, you can probably guess which one Im going to choose.
Hint: It might be this one. Then again, it might not.
