Sure, I'll bring it to the hackspace on Wednesday. Once its working properly I'll draw out the circuit and work out a decent PCB layout, unless there's a tool that will generate one automatically? As you can see I haven't put much effort into circuit layout and I'm just patch-wiring everything.

I'm using two circuit boards just to fit everything in, because the 7-seg display board needs to be small enough so it doesn't interfere with the back of the switches which means everything else has to be on a separate board.

I also need to update the final parts list and find the cheapest sources as this prototype is in the order of £30 and thats without buying wires, stripboard, LEDs and the two 4011's I'm using. I reckon another week or 10 days should be enough to have all that done.
