I mean something like sketched in the attachement:franksanderdo wrote:Hi Marcus,
sorry you lost me. YOu have an example, sketch?
Somthing a stupid electrcian can look at? ;)
See you around

- Everything goes into the base.
- From there a light pipe goes up with the LED PCB mounted.
- Under the light pipe a IR LED is mounted which transmit serial data in the Mhz range
- by some ingenious idea we cut a 'window' in the light pipe so that a photo diode on the LED PCB picks up the light of the IR LED
- The light pipe sits in a bearing with some gears attached which is directly driven by the motor in the base
- the LED PCB has a coil on the lower part which sits directly on the lower side and hovers over one or more other coils to produce the power for the LEDs (this will be funny too)
- The induction of the coil can perhaps be also used to detect the zero crossing of the turning LED PCB
By that we can somehow transfer the power to the LEDs and get the signals wirelessly in the LED PCB and can detect at which position the LEDs might be.
UPDATE: just rethinked it: I think it must be a rotating disk instead of a single line - my fault.
