Demo:
early test of features:
Its still a bit bright at night, so will look into dimming the display beyond brightness level 0
Using the HP bubble displays, a small, unobtrusive bedside clock, with day, date, seconds and (eventually) ambient light detection.

Bits arrived, the project happened :-)
Boxes were bought from the Range, I think they are meant for découpage or something but work well as little wooden project boxes it seems.
remove hinges:
Also, add extra magnets in addition to the 'clasp' magnet.
Cut hole for Arduino Nano to poke through (Power and programming):
A bit messy but the wood is softer than I thought, will be filled with something (probably hot-melt glue) and will be unseen.
Filled with glue making it flush:
Measure twice, and cut hole for bubble display:
Mount and solder the bits. including plug for front which allows the thing to separate into 2 parts, making it easier to work on just one bit.
The 6th wire (clear) is in place for future use with a light sensor, but it dims itself at 10pm and brightens at 7am so its not a problem at the moment.
Running:
I wish the camera would focus on LED's properly, but hey ho.

Ah yes, I remember seeing that in HaD, a very nice build, and I also, have had bad experiences with the DS1307 (when building https://hackaday.io/project/3045), cheaper but pretty useless as it does not have temperature compensation.

I built something similar http://www.instructables.com/id/Tnychron-A-Retro-LED-Bubble-Style-Display-Clock/ and figured out a nice way to mount the displays at the edge of the PCB. I'd stick with DS3231, as DS1307 drifts too much.
