Following the excellent tutorial by Jéjé l'ingé, I adapted his Time Circuit Alarm Clock model to be wall mountable and more accurate to the screen version with the keypad underneath.  

I've also updated the inner of the time circuits to give more space for the fiddly cabling that needs to be done in a effort to make it more tidier.

Keypad has been modified to allow a square 3 watt micro speaker to be fitted underneath, along with USB power.  (I ended up butchering mine as a 5V power cable was more suited for my installation after I completed it!)

I applied grey primer to all pieces and painted the time circuits with Hammerite Silver hammered metal paint and the keypad with Jenolite Sage Green rust spray paint.  Managed to source a white keypad from ebay in the end to make it easier than painting on the tutorial.

The labelling is from a genuine dyno printer.

It's a very challenging, but worthwhile build!
