With this thing I can control the colour of a bright light into many different colours using the three fundamentals colours : red green and blue. Adding them toghether with different intensity can yeld very great a range of colours from the visible spectrum.
Specifically my mood lamp can shift colours through 32 intensity values for each RGB colour giving
32*32*32 = 32768 different combinations of hue, intensity and brightness. It can also store 10 different combinations can be turned on or off, all of these through a TV remote control.
The intensity of each red, green and blue component is done via PWM so heat dissipation is kept to a minimum.
The circuit is simple and there are no pushbuttons as control is done entirely through the remote control.
I use this circuit to light a flower vase. The flat case of the box I chose does a good job at balancing the vase.
The pictures provide some ideas.
One day I am possibly buying one of those glass cubes with LASER created 3D shapes inside to go with the lamp. For now glass vases are just fine.
UPDATE : I uploaded V1.1 where at power up the micro outputs the values from memory number 0. Just make sure you store your power up colour in memory number 0 and at power up it will show up. If you'd rather go for lights off, just store all blanks in memory numer 0.
Hey I'm on the best of Instructables book !
