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!

In this video I open my mail. I got some stuff from Amazon and AliExpress:
The book that I mention I’m doing a new book teardown for is God Created the Integers, so keep your eye out for that coming up soon on the main channel.
The cable-making video I mention is this one: Electronics Project #5: Hook Clip Test Probes to DuPont Jumpers | In The Lab With Jay Jay.

For the record:
I’m having a problem with the YouTube player not working properly in my browser, and I demoed the problem I’m having in this video: YouTube responsive design issue.
Today I learned about Firefox troubleshooting mode.
Mum is roasting a chicken and my Air Quality Meter started alarming. The oven in the kitchen is smoking too much! This thing is super sensitive, it’s great, I’m glad I got it! The other day while I was soldering with the window closed it started alarming too. It’s good to have something reminding you about air quality.

At the pub the other night I met the guy who made this computer game: Kusan : City of Wolves.

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.
