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.

Silly Job Title: Chief Fuse Blower. I am the Chief Fuse Blower!
In this video we continue to work through our Maxitronix 30in1, today doing project #3: The One-Way Street. In this project we learn a little more about diodes and LEDs.
We use the EEVblog BM2257 Digital Multimeter to investigate voltages within our circuit.
We use the Sharp EL-546L Scientific Calculator to do some basic calculations.
We use the Carpenter Mechanical Pencil to make our notes.
We use the Kaisi S-160 45x30cm Repair Mat as our workspace.

Silly Job Title: Conductor Captain. I am the Conductor Captain!
In this video we take a look at the KY-010 Photo Interrupter. This module sets up a light beam and can detect when the beam is broken. We interface this module with an Arduino Uno after testing it with a simple circuit on the test board to figure out which pins are which. The pin labeled “S” is the signal, the pin labeled “-” is the negative or ground, and the middle pin is 5V VCC. The signal is high when the beam is interrupted and low otherwise.
There is more info about this sensor here: KY-010 Photo Interrupter Module at ArduinoModulesInfo.
Source code is here: 2025-10-06-KY-010-Photo-Interrupter.ino.
We use the Riden RD6006 Bench Power Supply to power our test circuits.
We use the EEVblog BM2257 Digital Multimeter to measure voltages.
We use the Kaisi S-160 45x30cm Repair Mat as our workspace.

Over in Intro to Data Oriented Design for Games, Nic Barker explains “taking information out-of-band”. Nic credits Andrew Kelly of Zig fame for introducing him to the idea (see Andrew Kelley Practical Data Oriented Design (DoD)).
The basic idea is that instead of having one list with items that have an enumeration with three different states, you can have three lists where membership implies the enum state, obviating the need to store the enum value in the item anymore, thus saving space and improving cache locality.

Silly Job Title: Chief Engineer. I am the Chief Engineer!
In this video we attach some alligator clips to a handful of AA battery holders. I was planning to use these for a Learning the Art of Electronics experiment that I didn’t understand, but now that I understand the problem a bit better I don’t want to go short-circuiting five AA batters… that would be a bad idea!
We use the METCAL PS-900 Soldering Station for soldering.
We use the MUIN Solder Fume Extractor to clear the air.
We use the EEVblog BM2257 Digital Multimeter for voltage and continuity testing.
We use the Hakko CHP 3C-SA Precision Tweezers for tweezering.
We use the Plato Model 170 Wire Cutter to snip, snip, snip.
We use the Kaisi S-160 45x30cm Repair Mat as our workspace.
