The eddy current discussion reminds me of a conservation of energy
demonstration. Get a hand cranked dynamo. As additional incandescent lamps
are connected to it, it gets harder to crank.

It's an interesting physics demo, but how "career" is it? More career
might be "the birth of a product." This could be a combination of slide
show and pass around stuff.

1. Slide of product definition meeting.

2. Slide of product definition document.

3. Slide of person doing schematic capture.

4. Screenshot of portion of schematic.

5. Pass around a copy of a chip datasheet (few hundred pages).

6. Screenshot of unrouted board.

7. Screenshot of routed board, especially showing multilayer.

8. Pass around a bare board.

9. Photos of automatic placement and soldering.

10. Pass around a stuffed board.

11. Screenshot of firmware flow chart.

12. Screenshot of firmware in C.

13. Screen shot of disassembled code.

14. Photo of debug session (person, PCB, computer, oscilloscope, etc.).

15. Couple screenshots showing single stepping and watch window.

17. Photo of final assembly.

18. Photo of production test.

19. Pass around finished product.

Let the kids know that this is what's behind every electronic product in
their home.
