Silly Job Title: Code Warrior. I am the Code Warrior!
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 investigate two mystery boxes.
The values we measure in this video are available in this spreadsheet: LAoE-01L.6.ods.
We use the METCAL PS-900 Soldering Station for soldering.
We use the AiXun H314 Hot Air Gun for heat shrink.
We use the Riden RD6006 Bench Power Supply to provide test voltages of 0.1 V through 10 V.
We use the EEVblog BM2257 Digital Multimeter to measure current.
We use the EEVblog BM036 Digital Multimeter to measure current.
We use the Fluke 17B+ Digital Multimeter to measure voltage.
We use the Brother P-Touch D210 Label Maker to make labels.
We use the WilliamKlein Music Stand to hold the text book.
We use the Carpenter Mechanical Pencil to make notes.
We use the Hakko CHP 3C-SA Precision Tweezers for tweezering.
We use the Plato Model 170 Wire Cutter to cut, cut, cut.
We use the Kaisi S-160 45x30cm Repair Mat as our workspace.

Hacking a cheap Temu router
This is fun.
Buy 12 Broken Ryzen CPUs for $10 Each and repair them for profit?
I was very impressed with how enterprising this guy is! Most just needed their pins straightened out, a few needed new pins, and two were salvaged for parts (i.e. pins).
1986 Sinclair Spectrum+2 repair
In this video I learned about the Metcal PTTC-706 soldering iron tips. I must save my pennies so I can buy myself a pair of these babies!
Deprecated master/slave signal names
See A Resolution to Redefine SPI Signal Names for notes about alternative names. I also noted in Getting Started with Arduino that alternatives to male/female are pin/socket.

Silly Job Title: Terminal Tactician. I am the Terminal Tactician!
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 test a 1N914 diode.
The circuit we build is this:
And the charts we make are these:
This demonstrates that as we increase the voltage into our diode the current increases exponentially.
We reverse the polarity of the diode to see what happens and we observe that only a very small leakage current of 0.4 µA flows.
We use the Riden RD6006 Bench Power Supply to supply 5V for our test circuit.
We use the EEVblog BM2257 Digital Multimeter to measure voltage.
We use the Fluke 17B+ Digital Multimeter to measure current.
We use the Carpenter Mechanical Pencil to make notes.
We use the Kaisi S-160 45x30cm Repair Mat as our workspace.

Alessandro Volta
Today I read about Alessandro Volta who is the person the “volt” was named after. Volta achieved a number of things but the most famous of them is the Voltaic pile, the first battery.
Arduino Project Hub
Today I discovered Arduino Project Hub. There are over six thousand projects there!
Low Tech Sensors and Actuators
Today I discovered Low Tech Sensors and Actuators while reading Getting Started with Arduino. It’s a report about how to salvage electronics from cheap toys to make various types of systems which can interact with their environment.
