John,
Isn't it amazing where this little semiconductor has taken us? I remember the first commercial red LED costing $10 and finally buying one at Radio Shack for $2 (I was making a buck forty an hour at Hobby House at the time). It was a pathetic red at that. I also remember when Cree developed the first blues at a mere $54 each.
My latest adventure in LED's was a PCB I laid out that was 1/16 x 2 inches x 1 mil thick and had 25 LED's on it. The LED's were 12 mil square, impossible to see with the naked eye. They were used in a process called photodynamic therapy. They activated an injected pharmaceutical thru a window catheter for prostate cancer.
I enjoy the latest in LED's. You can now get a truly accurate green for signals. And with the right code you can make truly realistic emergency vehicles.
