Computer controlled RGB Lamp Board      Computer controlled RGB Lamp heatsink

This project teaches you how to build a lamp that can change color, and can be controlled by a computer. Simple Python and C programs for your PC or Mac are provided that let you program color patterns into the lamp. Implementing the weather forecast and other ideas are then up to you. Web scraping with wget is easy if you understand a scripting language. The whole project should cost under 100 euro, half of which is for the lamp (glass ball, LED module, microcontroller, and odds and ends), and the other half for the flash programmer if you don’t have one. So considering you already have a programmer, the project should not set you back too much.
