I have not seen anything on this so that probably means we really need help. If you have projects you can bring - wonderful but not required. If you can demonstrate an oscilloscope that would catch a lot of attention. I can bring supplies for paper circuits. No experience is required to WOW kids and let them take home a circuit! Otherwise, just come and tell visitors what you like about DMS.
In 59 seconds, here is all you need to know to do paper circuits. This is the most basic. Google around and you can find neat designs to spice it up.

I will be bringing some projects from my Arduino-ish classes. I will be around much of the time 10-2.
