In this video I open my recent mail. Stuff that I ordered:

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.

John's feedback to Amazon for USB cable

Advice that my review was not accepted
