I received my linear servo today for my home made electronic shifter for my shimano alfine hub. The servo will be driven by a servo controller that receives information from a microcontroller. I just have to figure how to connect the servo to the bell crank housing of the alfine hub. My 400 watt power supply came today and despite the 40% conversion losses from mechanical energy to electrical energy my genset comes in at only 14 pounds.
