Silly Job Title: Capacitor Captain. I am the Capacitor Captain!
In this video we take a look inside Encyclopedia of Electronic Circuits Volume 4 by Rudolf F. Graf and William Sheets.
We noted while going through the book that πP is short for “microprocessor”, or, essentially what we’d just call a CPU these days.

Silly Job Title: Electron Enchanter. I am the Electron Enchanter!
In this video we continue to work our way through Learning the Art of Electronics. In this video we start 1L Lab: DC Circuits.
Today we do some experiments to determine the voltage burden of our DVM when it is in current-measuring mode.
We use the Riden RD6006 Bench Power Supply to power our test circuit.
We use the Fluke 17B+ Digital Multimeter to measure current and voltage.
We use the EEVblog BM2257 Digital Multimeter to measure current and voltage.
We use the EEVblog BM036 Digital Multimeter to measure current.
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.
