Automatic Transmission Selector

This is a selector that I made for my automatic transmission (http://www.thingiverse.com/thing:1094616).

It has an interlock mechanism and manual mode, so works like a real one. I made this model because I plan to print my automatic transmission and put solenoids controlled by Arduino, so I needed a way to select between modes, and even select each gear manually.

Why? Well, I have an engine model that runs like a real one and I want to put the automatic transmission and all that to simulate a car running on the road.

I already have a working sketch (program) for Arduino to control the solenoids on the automatic transmission, and I have the engine model working, so now all I need is a 3D printer to print all the transmission, selector, differential, etc. The wheels are going to be connected to a big flywheel to simulate the momentum of a moving car.

This project is not for everybody, but I wanted to share it anyway.

You are going to need 3mm rods, some springs and a 5mm s
