    I can certainly do that although I don't usually bother for things like this. I just go straight from idea in my head to prototyping strip board.

    I don't usually draw the circuit untill I get it working.

    I think I must have been a nightmare at college too because of this and I would never write a flowchart for a program until I had got the program working.

    Not a bad idea. I don't have one of those swing under the lens red filters on my enlarger but sometimes I wish I did as I might want to check something after I have put the paper in the easel or I may have accidently moved the easel in placing the paper and I need to see the image to put it back in place.

    Guys, I'm extremely interested in this, and have puzzzled over it for months - but I lack the enviable electronics skills that several of you appear have. If you crack it, PLEASE would you post a layman's guide (I can solder up a circuit if I know what to buy), or else consider selling a unit to a mere mortal!

    This site has good docs on spectral response of their LEDS:

    EDIT: They also have good links in their site. Here is a tutorial on mixing RGB LED light sources:

    this too!:
