I am trying to wire up about 90 red leds and 30 blue leds onto a rotating board. How would i go about this and use least amount of power possible. it will also be running off of a house plug.

Hello advanced MECP, You can do this, but it is very dangerous, because you want to use 120 volts ac. you will have to hook them up in a series parrallel curcuit, but once all of the light emiting diodes are hooked up and 1 blows, half will shut off. You will first have to hook 60 of them up in series + to - at 2volts each will total 120 then hook up the second batch in series + to -. Once you have 2 batches you will have to hook both inputs up in parrallel. you will have to calculate the proper resistor to use in order to limit the current going into the curcuit. good luck
