I made some notes about God Created the Integers by Stephen Hawking which I have been reading recently. I’m in the process of creating a new book teardown for it. I needed to make some notes about how to pronounce various names. I didn’t do this until I was half-way through the book though. If I had have taken the time to do this activity sooner I would have embarrassed myself less. Anyway. Better late than never!
For the record:
Today I learned about Firefox troubleshooting mode.
Over on Hackaday Give Your SMD Components A Lift they linked to How To Lift SMD Pins Safely – IC Pin Lifting / Soldering by Mr SolderFix.
There are some tips on making a website fast in this video: How is this Website so fast!?

In this video I do the 11th project from the Maxitronix 20in1 (the Sensor Robot 20): Burglar Alarm.
This project uses the reed switch to trigger a bistable multivibrator that controls an alarm. The bistable multivibrator can be reset with the key. An astable multivibrator is used to generate the tone for the audible alarm.
In this project we get some more experience with transistors and how they can be used in various types of multivibrator circuit. Under the thermal camera we can see some of the transistors warming up as they conduct electricity. With the oscilloscope we can see the periodic waveform used to generate the alarm tone.
Note: while I was making this video I needed to make some banana plug to hook clip cables (so that I could test the reed switch). I made a video of my making those cables which you can see here: Electronics Project #9: Making Banana Plug to Hook Clip Cables | In The Lab With Jay Jay.

I thought this was good: Seven things people learn too late in life.
Today I watched Most Important Skills for Electrical Engineering.
Stuff I need to learn includes:
He listed some important soft skills which included:
Today I found Quake ported to Arduino Nano Matter and Sparkfun Thing Plus Matter Boards via this article from Hackaday: Quake In 276 KB Of RAM.
The code is on GitHub and there’s a YouTube video with a high-level explanation.
