Nobody's brought this up yet but I am kind of worried about wear. On a normal cube, through doing hundreds of solves, the pieces get worn down a bit, and depending on the kind of electronics you put in this could prevent it from working properly. The contacts might not keep touching for instance; I know that on my cubes the pieces aren't always all touching each other, so if the contacts are on the surface of the pieces you might have a problem with the clock recognizing it's done when the cube is solved. (And yes, a *real* twisty puzzler would use it that much :) )

One way I can think of to fix this problem would be to have a much simpler puzzle, or else a much tighter one. For example if you had a 1x1x3 (or a tight but very well-lubed 3x3) you would not have as much problem with wear. The idea of a maze cube type solution (with wires on the cube's exterior) could also nearly eliminate wear but you would have to find a way to ensure they connect. Finally it might be possible to use a different kind of circuit; for example you could have a very carefully designed set of mirrors and holes, and embed a laser in one center, so that when the cube is aligned the holes line up and the laser hits a receiver in another part of the cube (although this would be very reliant on exact positioning). It's a tricky idea, I'd like to see if someone can make a model which will work despite wear or misalignment.

maybe take an already lube and broken in cube for the alarm clock cube

Someone suggested to me a flexible large diameter fiber optic for the circuit; like this 10mm one: http://www.anchoroptics.com/catalog/product.cfm?id=446

An LED on one end and a light sensor on the other end.
