Silly Job Title: Plugerinerer. I am the Plugerinerer!

In this video we continue to work our way through Learning the Art of Electronics. In this video we finish the first chapter 1N DC Circuits.

Today we do some experiments to verify Kirchhoff’s Voltage Law.

We use the Riden RD6006 Bench Power Supply for power.

We use the Fluke 17B+ Digital Multimeter to measure current.

We use the EEVblog BM2257 Digital Multimeter to measure voltage.

We use the EEVblog BM036 Digital Multimeter to measure current.

We use the Sharp EL-546L Scientific Calculator to crunch some numbers.

We use the Multicomp Pro MP701033 Resistor Decade Box for variable resistance.

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.

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.
