Latest Fatman and Circuit Girl vids

Education Technology

Here are some recent video clips from George Sanger and Jeri Ellsworth, aka The Fatman and Circuit Girl. In the first vid, Jeri attempts to build a Sprinthariscope, a tool for viewing radiation, using the radioactive Americium from a smoke detector. She also attempts to pronounce Sprinthariscope and Americium. All three attempts fail, but it makes for an entertaining and educational video.

In the second segment, Jeri has the entire Fatman and Circuit Girl crew in hysterics when she shows off her drive bay heating and cooling cupholder which employs a Peltier thermo-electric junction she’s overclocked to 16MHz using three early 8-bit microprocessors, a Z80, a 6502, and a 8088. Geek hilarity ensues.
