LCD Displays

The LED seven segment displays have one big disadvantage in that you can't see an LED in flurescent lights or in sunlight.

For this reason we explored using a seven segment LCD.

Findings:

Lumex: makes a .5" character height 2.5 digit LCD which can be had for 1.78 from digikey

Things which still need to be worked out.
1) need a higher AC voltage
2) need 14 (7*2 for segments) + 2 (switches) + 1 (COM pin)
3) doesn't save us any money
4) Package takes up an additional .1"

Possible workarounds:
1) perhaps not having the scr in the circuit and having the PIC go to sleep.

I ran across this article looking for something else and i'm posting it here in case i want to revisit this idea.
