I was reading the latest version of Make: Magazine, Make: Magazine, Volume 96, and I discovered this cool hardware based on the ESP32-S3: M5Stack Cardputer Adv Version. They are out of stock at the moment but I will have to check back later because I think I would love to have one of these!

John Teel explains microcontrollers to avoid

The microcontrollers to avoid and what to consider instead:

  1. ESP8266 → ESP32-C3
  2. PIC16 → ARM Cortex-M0+, STM32C0, TI’s MSPM0
  3. Ultra-Cheap No-Name MCUs → something with better doco and support, such as STM32C0 or TI’s MSPM0
  4. STM8 → STM32C0
  5. MSP430 → TI’s MSPM0
  6. ATmega328P → newer MCUs in AVR family
  7. Overpriced High-End MCUs → consider microprocessor instead

Help with Thevenin equivalent circuit

I was doing some prep work for the upcoming LAoE video and learning about Thevenin equivalent circuits, something I need to understand better than I do, particularly how to calculate Vth and Rth. I built the circuit on my bench, but then got readings I didn’t understand, so I asked about it over on the EEVblog Forum: Help with Thevenin equivalent circuit. In the end it turned out that my initial readings were wrong for some unknown reason, but when I repeated them they came out right the second time…
