Silly Job Title: Surge Sage. I am the Surge Sage!
In this video we continue to work our way through Learning the Art of Electronics. In this video we continue with 1L Lab: DC Circuits and do an experiment: try your DVM’s resistance measurement.
Today we do some experiments to determine the voltage used by our DVM when it is in resistance-measuring mode.
We use the Fluke 17B+ Digital Multimeter to measure resistance and voltage.
We use the EEVblog BM2257 Digital Multimeter to measure resistance and voltage.
We use the Multicomp Pro MP701033 Resistor Decade Box as our variable resistor.
We use the Carpenter Mechanical Pencil to take notes.
We use the Kaisi S-160 45x30cm Repair Mat as our workspace.

Silly Job Title: Joule Juggler. I am the Joule Juggler!
In this video we assemble the Children’s Science Technology Small Production Diy Telegraph Machine in the Science Experiment Equipment Stem Education Model.
The instructions were easy enough to follow, given they are in Chinese! We get the two circuits working perfectly. Really impressed with this one, it works like a charm! Didn’t do any range testing or what not, I’m going to do this one again when my little people come to visit.
