Silly Job Title: Wattage Warlock. I am the Wattage Warlock!

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 measure our DVM’s current output in diode test mode.

We use the Fluke 17B+ Digital Multimeter for voltage and current measurements.

We use the EEVblog BM2257 Digital Multimeter for voltage and current measurements.

We use the Carpenter Mechanical Pencil to take notes.

We use the Kaisi S-160 45x30cm Repair Mat as our workspace.

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: Component Wrangler. I am the Component Wrangler!

In this video we continue to work our way through Learning the Art of Electronics. We have nearly finished the 1N DC Circuits chapter. Today we learned a new rule of thumb: when circuit A drives circuit B the output impedance of circuit A should be equal to or less than 10% of the input impedance of circuit B.

There is no prac this week, only theory. Next week we will complete this chapter and then we’re ready to proceed into our first lab chapter.

Today over on the EEVblog forum I learned about the two ebooks available from Texas Instruments. One is for amplifier circuits and the other for data-conversion circuits, including both Analog-to-digital converter (ADC) circuits and Digital-to-analog converter (DAC) circuits. I had to sign up for an account before I could download…

Silly Job Title: Prime Hack. I am the Prime Hack!

In this video we take a look inside Encyclopedia of Electronic Circuits Volume 3 by Rudolf F. Graf.

Some circuits of interest included:

Page Circuit
245 Electronic Dice
327 Adder
337 Electrostatic Detector
594 On/Off Inverters

Some things we needed to look up while flipping through:

CMRR is Common-Mode Rejection Ratio.

RIAA is Recording Industry Association of America.

RIAA equalization is a specification for the recording and playback of phonograph records, established by the Recording Industry Association of America (RIAA).

PUT is a Programmable Unijunction Transistor.

φ (phi) can represent an angle, typically the second angle mentioned, after θ (theta).

PEP is Peak Envelope Power.

For voltage signals you usually want high input impedance and low output impedance.

LVDT is a Linear Variable Differential Transformer.

NAB is North American Broadcasters. They defined phonograph standards similar to the RIAA’s.
