This project builds a Christmas lights controller for the GE Color Effects lights allowing programmed control of up to 8 sets of Christmas lights. Furthermore, it provides a function specific language for programming patterns for these lights and an emulation environment for testing the programs requiring the lights to be built or hung.

If you have never heard of an Arduino, then I suggest you check out their site. They design and sell an open-source microprocessor platform which is great for building programmable electronic gadgets for those with limited electronics experience. GE Color Effects - These have to be the coolest Christmas lights ever for the hacker. Each bulb contains a red, green and blue LED and can be controlled individually or as a group by sending instructions down a single data line. For a description of what they are and how they work, checkout this article which also provides basic control information that Robert Quattlebaum (darco) reverse engineered. While you are at it, do some Youtube searching for some very cool demos of what can be done with a microprocessor and a set of these lights (The ten string Christmas tree has to be seen to be believed). The first program is the firmware which runs on the Arduino Mega to control the lights. It does this by reading a set of instructions which are expressed in the form of an array of short integers for each string of lights which tell the firmware what patterns to generate with the lights. The firmware can also be cross compiled and run on the PC where they can do the same job but control a lights emulator. On the PC, I use the express version of VC+ to compile it. The second program is the lights emulator. This will emulate one or more sets of lights arranging them on screen according to...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
