To all those asking about Blue LEDs, here's some info.

There are a number of them starting to come on the market at more useful
prices (still high) around $10 CDN (depending on quantities).

The blue LED that I mentioned is from Marktech, 5 Hemlock Street, Latham
New York, USA (12110).  Phone lines: voice # 518-786-6591, fax # 518-786-
6599.  The part numbers are MT1018D-BL (Diffused) and MT1018-BL (Clear).
Spec's are: Silicon Carbide, 470nm peak wavelength, Vf= 2.9 to 4.0 volts
at 50mA for a luminous intensity of 10mcd with a viewing half-angle
of 7 degrees.

Hope this help.  Cheers.
