Analog Meters for Learning the Art of Electronics
I was flipping through my copy of Learning the Art of Electronics: A Hands-On Lab Course (I have the first edition, this second edition comes out in Australia on 3 April 2025, I have a copy on pre-order, I think it’s already available in the USA) and I noticed that some analog meters are used in the first lab course.
So in preparation for doing that I purchased some analog meters, being these:
- DC Ampere Meter 91C4 Ammeter 1/2/3/5/10/20/30/50/100/200 A V Voltmeter Analog Panel Meter Mechanical Pointer 91C4 Ammeter (5V, 10V, 15V)
- 91C4 Class Ampere Analog Panel Meter Ammeter 2.5 Accuracy DC 50uA 100uA 200uA 300uA 500uA High Quality (100uA)
- 91C4- mA DC Pointer type milliammeter 1mA 5mA 10mA 50mA 100mA 200mA 300mA 500mA Analog Mechanics Plate table Ammeter (1mA, 10mA, 100mA)
- 91C4 Ammeter DC Analog 1A 2A 3A 5A 10A 20A 30A 50A 100A 200A 300A 500A Panel Mechanical Pointer Type Amper Meter Current Meter (1A)
I am planning to start working through these projects on my YouTube channel @InTheLabWithJayJay at a rate of one project every 28 days starting April 1st. April 1st, being April Fools’ Day, is of course the traditional date for launching IT projects and it is also the one year anniversary of my video (which happens to be my most popular YouTube video by a large margin): New Book Teardown #3: Learning The Art of Electronics: A Hands-On Lab Course (2016) | In The Lab.

This turned up in my feed today: CSS library based on Counter Strike 1.6 UI. I was particularly interested in how they implemented the tab panels.

Homework
This is a part of the homework feature of my blog, which is an ongoing conversation with my mate S.F.
Hey mate. Lovely to see you again, as always.
You told me about Gorilla Glue. Rather unhelpfully there are all different types.
I mentioned my manifesto. Everyone should have one. :)
The Everyday Spy is Andrew Bustamante.
A PhD involves a thesis defense.
I have a note here “star app”, but I’m not sure what it refers to? Do you remember? I did search for “star app“.
This is required viewing: Bogans.
See you again soon! <3
EXTRA HANDS FOR SOLDERING – OCTOPUS
I accidentally happened upon this while surfing the interwebs this evening and I thought it was a great hack: EXTRA HANDS FOR SOLDERING – OCTOPUS. This person makes a very respectable third hand out of a few scraps.
Spare steam keys
I purchased this Humble Bundle without realizing I already owned most of those “games”. I now have spare keys for:
- Nanotale – Typing Chronicles
- You Can Kana – Learn Japanese Hiragana & Katakana
- Terra Alia: The Language Learning RPG
- Epistory – Typing Chronicles
- The Textorcist: The Story of Ray Bibbia
These keys are free to good home. If you’re interested PM @jj5 on libera.chat and I will send to you. (I will cross them out of the above list when I give the key to someone.)

I am so impressed! This guy made his own robot: story.md.
