Hi all,
been away for a while but am now back and restarting work on my HDD based audio player. I want to have a scroll wheel (approx 60mm diameter) to select songs and am investigating ways I can use to light the wheel with small leds inside the dial/wheel (purely for cosmetic reasons). The wheel will be on the front face of the player so that the axis of rotation points to the user.
Recently, I dismantled an old VCR and noted how the video heads embedded in the shiny silver flywheel transfer their information via coils in the spinning drum to ones fixed outside.
Unfortunatly I couldn't get the coils out in one piece, but I am wondering if I were to make coils similar to this I could transfer enough power to light 4 or more LEDs inside my wooden scroll wheel?
