I want to make a DIY Power PUC to put led's on my motorcycle. I plan to use 5050 RGB strips. Power supply to these LED's will be in the form of a carbon brush - aluminium ring assembly. But since the wheel will be rotating there will be fluctuations in the current reaching the LED on the wheel through the carbon brush. Hence I was thinking of using capacitors to tide over the current drops. These capacitors would be attached between the aluminium ring and the LED wire.
I would like to know how I should calculate the capacitor required and how to connect it - in series/parallel, and whether any other components will be required for this purpose.
