I found that I couldn't order the solid buttons from Farnell as they have just started slapping a minimum order quantity on; so I was going to get a set cast. At the point where I tried this I found a chap locally with a laser he uses to cut steel plates; he can punch a 0.5mm hole through the buttons for me with no effort, so I think I will go for this route.

I have got a supplier of blue LEDs locally, so I'll be buying up a batch soon.

As for wiring in the tracking and mounting the LEDs - no, not yet. This is something I'll be starting in the next month or two so I'll let you know.
