I’ve been going at In The Lab With Jay Jay for a bit over three months now, and I finally got my first comment on YouTube that wasn’t from a friend of mine:
Do you know they based lester crest from gta v on you?
You literally have the same look and the setup is similiar to his in game lol.
I finally got around to reading about YAML at Wikipedia. Worth doing if you use YAML anywhere and haven’t read the YAML page yet.
The Wikipedia article links to the official website: yaml.org, which is good fun. It’s written in YAML! :D
If you’re interested in data formats and markup languages here’s some other reading on the subject:
This guy, Cathode Ray Dude [CRD], does some fun stuff. He’s on the web via HTTPS at gekk.info and HTTP at www.cathoderaydude.com.
I think I have roughly 500 zip ties in my drawer. Should take me a while to get through those! I have other ones, but these 150mm ones are my fav.
I made a rack for my network switches out of old coat hangers and craft sticks.
I have an item on my TODO list to make a program to convert text into Title Case. On a whim, I asked ChatGPT to do this for me, and it did! ChatGPT is automating me out of work!

In this video I unbox two “different” helping hands (AKA “third hand”) only to discover they are the same TE-801 model.
I purchased these separately on AliExpress:
They are exactly the same product so if you’re planning to purchase might as well get the cheapest option. Note that the first link above also has a separate more expensive option which is actually a different product, I didn’t get one of those.
In addition to unboxing these third hands I also add some 4mm heat shrink to the alligator clips to take the bite out of the teeth.
Note: in this video I have the annoying habit of calling “heat shrink”, “shrink wrap”. The correct term is heat shrink, shrink wrap is a different type of thing.
In the video I use 4mm yellow heat shrink:
The hot air gun I use is a part of my Horusdy Soldering Station.
The batteries I use are Duracell AAA batteries.
My gloves are:

Got myself a USB powered UV light. It came with a few tubes of solder mask:
I’m gonna keep this in my booth where it will be used. Don’t want to use it anywhere near where I keep my UV solder mask because I don’t want to accidentally cure it!

In this video I solder three different sized bodge wires onto some perfboard for practice and for the purpose of exposition. After attaching the three bodge wires I cover them with UV solder mask.
If you haven’t heard of the expression “bodge wire” before, ChatGPT will explain.
I want to thank my mate Bruce from Branchus Creations for recommending the enameled wire of various sizes, the Swann Morton blades, and the Amtech flux.
I got three rolls of this enameled copper wire from AliExpress:
The diameters of the various rolls I got were:
| Size | mm | inches |
|---|---|---|
| Small | 0.07mm | 0.003″ |
| Medium | 0.16mm | 0.006″ |
| Large | 0.31mm | 0.012″ |
I got the “coppery” colour, not the red stuff.
The Swann Morton blade handles I got were these:
I got three types of blades in #15C, #15, and #10 sizes:
The #15C Swann Morton blade is the smallest and is so far my favourite. The #15C is the blade I use in this video.
My flux is:
