Hey Dave,
A few of my favourite videos of yours have been the tour of Channel 9, the tour of the SMD manufacturing place, and the tour of the calibration container.
You seem to somehow effortlessly tap into fellow engineers brains when interviewing them, probably mostly because you aren't some douchebag journalist, but are actually one of their peers asking intelligent questions that demonstrate some understanding of the subject.
Anyway whatever it is, I love these vids and would like to see more like them.
Thanks for the truly excellent contribution you make to the industry and to education.
James
