Mail Call #14: Loot from Amazon and AliExpress: Cables, Micros, and More! | In The Lab With Jay Jay
This post is part of my video blog and you can find more information about this video over here.

In this video I open my recent mail. Stuff that I ordered:
- New Pro Micro for arduino ATmega32U4 Module with 2 row pin header For Leonardo in stock . best quality
- JYHealth Medical Household Infrared Digital Ear and Forehead Non-contact Laser Body Thermometer LCD Baby Adult Fever Temperature
- AmazonBasics 3.5mm to 2-Male RCA Adapter Cable – 1.2 Meter
- DKE PC Power Button Desktop PC Computer Case Power Switch On Off HDD Push Computer Host Button Supply Supplies with 2m Cables
- BIAL Red-blue 3D Glasses with Case Glassese Cloth 2 Pack Cyan Anaglyph Simple style 3D movie game- Extra Upgrade
In the video I mention that I made some notes about how to pronounce famous mathematicians’ names, those notes are here: God Created the Integers.
In the video I mention the Arduino Leonardo and the Arduino Micro which I am using for my MIDI-synth project: Crustaceans Chirp Chirp Challenge. Both the Leonardo and the Micro are based on the ATmega32U4 microcontroller which has built-in USB support.
My audio cables are so that I can connect my new gaming rig ‘treat‘ to my Logitech Z607 5.1 Surround Sound Speaker System Bluetooth.
The NASA Astronomy Picture of the Day for 2024 November 15 is what I needed the 3D glasses for. Unfortunately they didn’t work particularly well for me. Oh well, can’t win ’em all.
Also, I figured out how to use my thermometer properly by reading the manual. Go figure. The thermometer supports two modes of operation, forehead and ear. So it works properly if you use it correctly.

Amazon feedback
I don’t usually send feedback but I stumbled upon an email in my inbox asking for feedback on this purchase so I figured I would tell them what happened.
lol. And then it turned out they only wanted a review of the product, and not a review of my customer experience. I am now reminded or why I don’t usually send feedback.

STM32F1 Pico Pwner
I was searching for info about picoPower and I accidentally found STM32F1 Pico Pwner. Looks pretty interesting! It seems to be using power glitching to bypass locks so firmware can be dumped from certain microcontrollers.
