I finished the main functionality for the scope last week and took to the University of Alberta Engineering DiscoverE camp for a demo. It was the main, end demo for a little talk I gave a grade 7-9 "Awesome Arduino" campers on the idea of "software-enabled everything". 

It was a lot of fun to be there and answer some very good, and sometimes hard questions. They all got to play with the scope. I'll get to present to campers in the second round Aug 10th.

All that remains is to update the Fritzing file, fix a bad encoder button red LED wire, and tweak and update the arduino source. Then, of course, post it all.

Then on to the next project!
