I just got Jeri Ellsworth’s web video shows on my radar, namely The Fat Man and Circuit Girl. She and co-host George Sanger do an awesome job of explaining electrical engineering, science concepts, and various forms of hackery in a clear, straightforward, and fun way.
Jer’s just started experimenting with short videos, with limited editing, of her describing something that’s caught her interest, like a video lab journal. This vid, Short Circuit #1, is her describing how an analog falling edge detector circuit works (and yes, she knows that she said “variable capacitor” when she meant “variable resistor”).
BTW: Jeri will be at Maker Faire in May! She’ll be showing off her Easy Bake Oven chip lab.
