I compromised on my original high aspirations for a case. Perhaps I'll make a better case another time, but for now I have a nice wood case with a plastic face with -12V, 3.3V, 5V and 12V binding posts alongside 4 ground posts .75" apart to find the dual-banana plugs should I ever run into that. I also hot glued two LEDs at the bottom under the plastic. The yellow is standby and the green is on. I also put a power switch in instead of letting it be always on even though I have a switch on the back of the original box.
ED (Electronic Discovery) is specifically designed to engage a family with a friendly faced gadget which is easy to assemble, write code for and encourages them to interact. Ideally this makes electronics a family hobby rather than something Dad does alone. Older children could find much opportunity to learn a bit about electronics by studying schematics and assembling ED. Younger children's minds will begin to be engaged with the idea of making things and will begin to pickup the basics of electricity as they see schematics built and learn component names.
