We recently covered voltage dividers in our Ask MAKE column. In the above two videos, done by our pal Jeri Ellsworth, computer industry legend Lee Felsenstein (member of the Home Brew Computer Club and Osborne designer) explains voltage dividers and how to calculate them. Things get pretty thick by part II and I pretty much got lost, but sharper math heads should prevail. These videos are labeled as “Lessons from Industry Legends.” What a cool idea. I hope Fatman and Circuit Girl do more of these in the future.
