Nativity scene
IMG_0138.JPG Every year me and my friends build nativity scene in our church.
Every year all change!

Some of electronics (apart 25W cfl bl bulbs, led strings and dimmer) is made by me.
All "low" power leds (1w and 3w) are fed by 12v with current limiting resistors.
3x cree CXA2011 are fed by 15vca via voltage doubler and limiting resistors.
All statues are driven with relais (+ snubber).

With this intelligent lighting, we reduced power requirements from 300w (excluding pc) to 100 (half is to power 2x cfl bl, and 30w are used for cctv, nativity control and music jukebox homemade atom pc)
