What Jason does at school

I am taking a one day break from my beautiful girlies, and bragging about my third child today...my smart hubby. He has been working hard in his Engineering lab to build this board that I guess "amplifies things"...I don't pretend to understand, but he built this from scratch, and I have been watching him fiddle with all these little pieces, and yesterday he officially completed it...yay! So now he is down to "just" three classes for this semester.
