Bottom case
The DSKY aluminum case is not deep enough to comfortably fit the power supplies for the EL wire and any connectors I add. Thus, I designed a 3 1/2" box that will fit underneath. On a side note, the resulting combined size is closer to a real DSKY. I designed this from 9mm thick acrylic and sent the work out to Ponoko.
For connectors to the outside world, I chose to use a very similar connector to the one selected by MIT in their design of the DSKY. It is a Bendix 85 pin circular connector, readily available on eBay and on its way to me. I chose a similar but smaller two pin connector for my main 5V supply to the unit.

Connector to AGC signals and power |
Ben Krasnow created a true electroluminescent panel as a replica of the one used on the MIT DSKY, as announced on his (watch video) Applied Science YouTube channel. He has loaned it to us and I now need to find a way to make use of this marvelous creation in the short time left before we are again working on the AGC.
Once I pick it up, I will see if its size is suitable to fit inside the aluminum enclosure I am working with on my DSKY replica. If it is, then I can remove my 7-segment display parts from my PCB, drop the mounting of the PCB lower and place his panel in the enclosure opening. His replica is programmable over USB serial link, which I should be able to accommodate from my Arduino in my replica.
The worst case situation is that I can't fit it in, thus we will need to use my replica as built with his panel sitting beside it and linked over USB cable. More on this soon, once I have completed the measurements and detailed planning.
