Museum TV installation

[Brianc]

I did some PCB design for a small audio company and part of their brief was to have a 0V star configuration with every stages' 0V tracked back to the star point which was a 4mm "bolt hole" as part of the mechanical fixing. It proved a nightmare to implement with so many tracks going from east to west. That had to be a 4 layer board but it was great fun doing it (better than solitaire)! I also did a microprocessor card using a BGA. That had to be 6 layers. I still have the software but I'm sure that it would take me ages to get back into it.
