Throttle interface for electric vehicles. I designed this one specifically around the Xie Chang line of controllers which are quite popular with the ebike crowd. I ride a high powered bike and the throttle is very sensitive to movement. What I've done is tried to solve some of that by building this micro controller circuit which allows me to convert the throttler interface from linear to an exponential curve so there is more resolution in the low range and less in the high range. It also allows you to adjust your voltage start point and end point so you are able to get the full range of motion out of your throttle. I also added an adjustable filter/delay that is variable from 0 to about 2 seconds. This should help to smooth out throttle transitions especially on rough terrain. If you have a setup with some power you are probably quite familiar with how hard it is to hold a throttle position over bumps. If you ride a really high powered setup then you've probably ended up in unintentional unicycle mode more times than you would like.
