The original mimic panels were built using commercially available console cases.

As our experience with 3D printers has evolved, we can now print complete cases that are smaller and lighter that the units that we used previously.

We now have new station and fiddle yard panels, both freshly printed but we need to start and implement the wiring necessary to connect individual bulbs and switches to the electronics.

However the first task was some fault finding on a panel control module. The problem was that the switch circuitry worked but the module would not light any LEDs. One chip on the board was identified as a candidate but doing some chip swops with a working board proved that this was not the case. Ray suggested it might be the microcontroller and after some further chip swops this proved to be the case.
