“Control the colour of a powerful LED light beam with a remote control, store the colours and recall them at will.
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.” – Link.
