Hey all... I've got a bit of a major hobby project under way... and I need some help and suggestions when possible.
To start, I am building this project under the idea that ambient light improves your viewing conditions and helps you enjoy your movie/game whatnot more... and it looks cool.
The project I have in mind is to use the
- K2805 Dick Smith Parallel port programmer
[/URL]- LED lights
(probably 3 - red,green, blue depending on how i can do it)
Now, the idea is that I will use the analogue outputs of the K2805 interface so I can have the computer read what is on the screen, convert it to a single colour (ie red would be 255, 0, 0), and put that out to a Led or other light to get it going.
in other words, I want to be able to put out a "red" light, and then change the same light to be a "orange", or yellow, or a lighter yellow...
Another question I have, is that I have seen LED powered Eggs, that flash in a variety of colours. Picture here:

[url]http://www.pccasegear.com.au/prod3833.htm
And link to the page for them.
Does anyone know how these work? and also, would i be able to programmaticly change their colours using an interface of any kind?
What do you guys think?
Here is an example of the inspiration behind the project - phillips tv with ambiLight:

Maybe I should take small steps and rephrase -

What makes these lights work? and would I be able to modify it or tweak it?

Same way, with LEDs and a microcontroller, excpt the microcontroller is likely hard programmed to do its thing.
I know you can get programmable LED lamp assemblies, which resemble those touch lights.

Would it be possible to make a simple controller to accept inputs from the K2805? It can supply a variable voltage (i think its from 0-5v, 255 steps), and replace the light possibly?

Any modern microcontroller can provide PWM, which can provide a likeness of variable voltage.

You could try looking here: xxxxxxxxxxx. It simplifies the process a lot.
