Thanks for putting your clocks up on the net. I picked up a couple of the the HP Bubble displays as soon as I saw them and had been wanting to use them in a clock but hadn't the means so your design + code is fantastic.
I had a couple of questions, if that's OK:
1) - The schematic has a couple of caps, notably one by the buzzer, but the built item doesn't seem to neither does the photograph of 'parts'. Should the caps be used?
2) - The voltage from a single AAA is below spec for the chip, display, & buzzer. Doesn't this matter?
3) - You don't have a resistor in series with the LED, would it be good to put one in, if part+room available?
Also I'm envious of your neat tac buttons as I weary of the ubiquitous black round rod type, do you have a part # or source for them - also the LED which looks a nice rounded edge shape for free mounting, all the rectangualr ones I've seen are very hard edged.
Thanks again, Vicaro
