Over the break I am going to start experimenting with and programming the Arduino board to prepare it for the shifter. I will probably use the time as well to ask around and try and find the kind of shifter I need. If I can use parts from the kit to use as switches I probably will. I expect it will be easy to find a shifter and a brake but you never know here in Bali.
I have revisited and revised my clutch system and decided that by using an old bike brake, the spring would be implemented in the brake. By running the cable through a directing tube I could make sure it pulled the switch straight and not possibly break the brake by pulling in the wrong direction.
