This might be considered overkill but I have completed a clock which uses the B-7971 Smart Socket design to control six SP-252 displays giving 12 digits on which time is displayed along with date, temp, pressure and 10 different scrolling text messages (each of 70 characters in length).

The clock consists of a backplane, the smart socket boards (twelve of them, two per display) and display holding boards.

The software now has a web gui which provides access to all the settings as well as the user definable text messages. Many thanks to Paul Andrews for helping with this.

An optional PIR device will wake the displays from sleeping whenever it is activated and the whole thing is held together within my regular (one trick pony!) acrylic case design.

Although it is not clear in the pictures, there are two individual smart socket PCBs per display, one on top and one underneath. After the initial test build I elected to have the smart socket PCBs pre-fabbed, they are double sided and each one has 30 x 0603 resistors and 15 x MMBTA42 transistors.

Why have just one micro in a clock when you can have 13!
