This is an easy way to make your own $50+ value mood light with a minimum of parts/effort/Cost and electrical or electronic experience. Even soldering can be avoided!.
Total cost could be as little as $2.
Step 1: The heart of the mood lamp
The heart of the mood lamp is the colour changing light. Bright LEd systems driven by complex microprocessor systems are detailed elsewhere in instructables but this uses a commercial easily available colour changing LED from www.Rapidonline.co.uk if you are in the Uk or search fro colour changing LED or rainbow LED in Ebay or google for your country i am sure you can find them. Here they are £0.56 or so each.
The LED contains a red - Blue - Green LED and a minute microprocessor inside a standard 5mm LED package - IT IS SMALL. All you need is to apply 3 volts to the LED to make it work.
