 MR> Those displays were a sort alphanumeric. The word digital only applies
 MR> but when some kind of computer counter logic circuit is used.

Nope, digital in this case means "using digits". A digital clock
displays the time in digits, 0, 1, 2, 3, etc.

The other type is an ANALOGUE (or ANALOG) clock where the
movement of a hand around a dial is analogous to the smooth and
continuous passage of time.

 MR> Otherwise  things like mechanical odometers would be considered
 MR> digital.  

Which of course they are ;-)

 MR> Speaking of displays, I just purchased a surplus white light led the
 MR> other day in the standard size package and I was curious, seeing how 
 MR> very bright it was, how many mcd's this thing emits. The funny thing
 MR> is  the led white light seems slightly bluish, rather than what we are
 MR> used  to from incandescent lamps but it looks different from
 MR> fluorescent.  

Yes, I have just built up one of Dick Smith's kits, for an LED
torch using a white LED. The interesting part was the electronic
circuit that allows it to run from a single 1.5v cell, although
the LED needs about 3.5v or so.

It is really brilliant, IMO a lot more light than the original 3v
bulb, and for only a third the current!

I bought it three or four months back for about $27. Last month
they were on special at $17 IIRC.

Ain't that always the way?
