My IRC friend dcz referred me to this: Spintronics: Build Mechanical Circuits. Definitely need to get me one of these!

John Teel explains microcontrollers to avoid
The microcontrollers to avoid and what to consider instead:
- ESP8266 → ESP32-C3
- PIC16 → ARM Cortex-M0+, STM32C0, TI’s MSPM0
- Ultra-Cheap No-Name MCUs → something with better doco and support, such as STM32C0 or TI’s MSPM0
- STM8 → STM32C0
- MSP430 → TI’s MSPM0
- ATmega328P → newer MCUs in AVR family
- Overpriced High-End MCUs → consider microprocessor instead
String case
We have camelCase, PascalCase, snake_case, Pascal_Snake_Case, SCREAMING_SNAKE_CASE, and ALLUPPERCASE.

Silly Job Title: Transistor Troubadour. I am the Transistor Troubadour!
In this video we do the 11th project from the Maxitronix 30in1 Electronics Project Lab Kit: The Beacon Light.
We use the Rigol MSO5074 Mixed Signal Oscilloscope to examine the waveform.
We use the UNI-T UTi260B Thermal Imager to check the thermals (there wasn’t much to see).
We use the Kaisi S-160 45x30cm Repair Mat as our workspace.

Silly Job Title: Spark Slinger. I am the Spark Slinger!
In this video we continue to work our way through Learning the Art of Electronics. In this video we finish 1L Lab: DC Circuits by learning how to use our oscilloscope and function generator.
We use the Rigol MSO5074 Mixed Signal Oscilloscope as our oscilloscope and we use the UNI-T UTG962E Signal Generator as our function generator.

p.s. today I added slinger to my spell check.

Silly Job Title: Volt Vanguard. I am the Volt Vanguard!
In this video we do the 10th project from the Maxitronix 30in1 Electronics Project Lab Kit: The Highs and Lows of Oscillation.
The spreadsheet with our measurements is here: Maxitronix-30in1-10.ods.
We use the Rigol MSO5074 Mixed Signal Oscilloscope to measure the period of our circuit’s oscillations.
We use the UNI-T UTi260B Thermal Imager to check the thermal properties of our circuit. There was nothing exciting to see.
We use the Carpenter Mechanical Pencil to take notes.
We use the Kaisi S-160 45x30cm Repair Mat as our workspace.
