Main light modification in progress
The XML T6 charging light is the basis for the main light. Connection of microswitch for extended control on handlebars. Additional LEDs for daytime running lights are added around the perimeter of the main light
Still in progress! Last update 22.9.2019
素子 Motoko
Why Motoko? First of her kind of course! According to Masamune Shirow-Ghost In The Shell, where Motoko is the main character in the story. Cyborg, one of the first of its kind.
I want to be part of the future and create something for it.
