In this video I fix up and reassemble my Here There Be Makers badge which I received from Maker Shed in California.

John's Makers PCB badge

This electrified badge was made by lectrify.it and PCBWay.

Previously I had installed a single 3mm LED in the top of this thing, but in this video I remove that (so I can use the hole to hang it) and install two 3mm LEDs on the front instead, which is my best guess as to what I was supposed to do with this thing, which didn’t come with instructions.

There is some information about their Maker Faire event on in San Fransisco later this year over here: https://make.co/welcome/

And also, yes, I should have combed my hair before making this video. :P

In this video I take a look at some new books and equipment which has arrived in the mail:

I mention in the video that I recently organized my USB cables.

There’s some more information about where I found and purchased my Fluke multimeter over here: Fluke 17B+ Multimeter. Shoutout to my mate @ElectrArc240! When I release the unboxing video for this meter I will update this page with the link.

At the end of this video I put together my “Maker Faire: Here There Be Makers” swag but I actually revisit this and do it better in another video released as an interlude on the channel, so stand by for that (it will come out tomorrow, I will update this link when it’s out).

Old Book Teardown #9: Basic Electronics – Volumes 1 through 6 (1955) | In The Lab With Jay Jay

I mostly published this ten hour long video just to exasperate Dave Jones. ;)

Silly Job Title: Buzz Boss.

In this video I take a good long hard look at the entirety of this book.

The book is Basic Electronics – Volumes 1 through 6 written by Van Valkenburgh, Nooger and Neville, Inc. and published in 1955.

The book is about the state of electronics at the time it was written. It was commissioned by the United States Navy, who used it to train their technicians. Later, it was released for civilian use.

In the book there is lots of material on vacuum tubes, which were state of the art at the time. The sixth volume adds material on transistors and frequency modulation, which were bleeding edge technology at the time.

I learned heaps from reading this book, particularly about the various types of vacuum tubes (also known as “valves” by the British): diode, triode, tetrode, pentode, and Klystron, among others.

Also I learned that the name “transistor” is a contraction of “transfer resistor”, I didn’t know that!

Today I was organising my media files and I found this old video. I recorded this back in August 2023 but I never released it. I think back then I didn’t have this second channel and I decided this video wasn’t good enough for the main channel, so it just kind of got forgotten. But I thought it was fun so I have published it here for the record.

In this video I do a time lapse of me cleaning my resistors. While the time lapse is playing I include a narration in which I discuss things I had been reading at the time. There are two links for the show notes, being these:

In my dream last night I asked ChatGPT about… me. When I woke up, I did the obvious thing:

This is the inaugural Mini Project! I introduced the Mini Projects recently. They are developed and published by Silicon Chip magazine, and sponsored by Jaycar Electronics (which is an Austrlaian electronics store, similar to Radio Shack in the USA, hopefully it doesn’t end up suffering the same fate.)

In this project, codenamed JMP001, we develop a USB keyboard which can send interesting and unusual symbols (which aren’t usually available on a keyboard) to a Windows computer using the alt-codes that it supports in a typical codepage.

For this first Mini Project I felt it was important to actually buy my components from Jaycar which I did for roughly eighty Australian dollary doos. Approximately US$50. The parts I ordered were these:

Belatedly I did also search for rubber feet.

There was quite a lot that went into the production of this video, and we accumulated a lot of links. Those are here:

In the end this first project was relatively successful, and we did get it to work fairly well on one of my Windows computers. As for the rest you can find out for youself in the video!

In this video I do the tenth Maxitronix 20in1 Electronic Project Lab project: Speech Conductor.

In this project we learn a little about transistors, amplifiers, and astable multivibrators.

Note: while I was making this video I took a detour into making a cable, which didn’t work out. You can see the video about that over here: Extra Content #13: Failing to Attach Banana Plugs to Microphone Cables | In The Lab With Jay Jay.
