Silly Job Title: Science Officer
Today we’re gonna take a look at what arrived recently from AliExpress. They were having a sale so I purchased some natty tools and a few consumables. Details below. I made some notes at the time of purchase if you’re interested in what I paid for this stuff.
In the video I refer to the workstation I am planning to buy for the studio. When I get this new computer I should be able to improve the quality of my YouTube videos. If you’re interested in the details the new computer I’m planning is ‘victory‘. In the video I say this new computer will cost me AUD$6,000, but it’s looking like it will cost more like AUD$7,500 (roughly USD$5,000), so I will have to save my pennies! The Dell OptiPlex computer that I am presently using is ‘wonder‘.
In the video I refer to “box openers”. If you know what these things are actually called, please do let me know!
The spider who popped up on my bench during the recording of this video was found later. He, um, didn’t make it…

Let’s go shopping!
AliExpress sale
Today there was a promotion/sale on at AliExpress, so I picked up some consumables and a few natty tools. I paid the promotion price AU$63.46 for stuff on sale at AU$142.82 which normally sells for AU$326.12.
AliExpress sale
There is a sale on at AliExpress today. I picked up the following AU$881.75 worth of stuff for AU$225.03 (inc. tax and shipping).
AliExpress diodes
I ordered a bunch of SMD diodes from AliExpress (nine different types), and nine packages arrived, but they weren’t labeled. I tested everything to infer what I got, and they didn’t ship me what I ordered. My notes are here and the video of me doing all this is here.
I kept a note of the seller and will try to not order from them again. In the mean time I think I have filed the components that did arrive in the correct drawer.
Below are two happy snaps from this project. I guess on the bright side I got some practice doing SMD soldering and using my signal generator and my scope.
Oh, and I added a new item to my debugging notes, viz “is it plugged into the right socket?” (I had my output cable on the signal generator plugged into the wrong BNC connector on the device, that took some figuring out…)
Switching diodes and rectifying diodes
I had an envelope full of SMD diodes arrive today. Three different types in three different sizes, so nine bundles. Unlabeled!
I’m not sure what they were thinking at the shop. I got them from here.
I managed to figure out that the ones marked ‘S4’ were the Schottky diodes (1N5819WS). I think the ones labeled ‘T4’ are the switching diodes (1N4148WS) and the ones labeled ‘T7’ and ‘A7’ are the rectifying diodes (1N4007), but I’m not sure of that yet.
I asked ChatGPT for help and it explained how I can devise a test circuit, so that’s on my TODO list for tomorrow.
Unboxing #5: Unboxing of AliExpress TE-801 Third Hand With Magnifier | In The Lab With Jay Jay
This post is part of my video blog and you can find more information about this video on this show’s homepage which is here.

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:
- 3 Hand Soldering Iron Stand Welding Tool With Magnifying Glass Illuminated LED Alligator Clip Holder Clamp Helping Repair
- Desktop Soldering Holder Welding Equipment Auxiliary Tool Third Hand Helping Repair Tool Magnifier LED Lighting Soldering Stand
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:
- 24Pieces/12 Pairs Work Gloves For PU Palm Coating Safety Protective Glove Nitrile Professional Safety Suppliers Color: PU1350NV -DMF; Size: S

Homework
This is a part of the homework feature of my blog, which is an ongoing conversation with my mate S.F.
I said I found a microscope cheaper on AliExpress than on Amazon, but actually I was wrong about that. In fact I found it cheaper on eBay ($333.29) than Amazon ($733.42). Nevertheless, my point stands. It pays to shop around!
I mentioned my video jj5 feels hardcore!. Let me know if that doesn’t play for you, I think I have the original kicking around somewhere… If this video doesn’t make you happy, nothing will… :)
You told me about Louis Theroux’s Weird Weekends.
The I-can’t-believe-it’s-not-satire lawyer/jailer thing I mentioned is documented here: Um, America?
The academic accident I referred to was in The Hardware Lottery by Sara Hooker published in August 2020. In the essay the author says “risk adverse”. Of course the idiomatic expression she is aiming at is “risk averse” and she just got it horribly wrong. Not once, but twice. As I said, for a professional academic ignorance at this scale is… unbecoming.
My comment about academic whinging was: “There’s nothing more sleep inducing than a pompous academic having a whinge.” (If I could refer you to section three of the policy document, subsection five, article three A, there is a discrepancy regarding some thing I do not give a shit about…)
I mentioned How It Works (girls suck at math!)
The full quote is: “‘Why?’ is a stupid boring question to which all honest answers are a deception of the mind.” — John Elliot V
I mentioned Creative Act: A Way of Being by Rick Rubin. I will bring you your copy next time I see you. :) In the mean time you might enjoy: Rick Rubin: Legendary Music Producer | Lex Fridman Podcast #275.
Don’t forget to send me the name of the Sony headphones you recommend.
The LCD Soundsystem you mentioned was You Wanted A Hit. Classic.
Let’s not forget: It doesn’t have to be a bad thing!
Also, let’s not forget: everything you do is indelibly wrought in space and time. (No pressure.)
Also: hope is not a strategy. (Although some do not agree)
What is the difference between hope and faith?
Hope:
- To wish for a particular event that one considers possible.
- To have confidence; trust.
- To desire and consider possible: synonym: expect.
- The assent of the mind to the truth of a proposition or statement for which there is not complete evidence; belief in general.
- Specifically Firm belief based upon confidence in the authority and veracity of another, rather than upon one’s own knowledge, reason, or judgment; earnest and trustful confidence: as, to have faith in the testimony of a witness; to have faith in a friend.
- In a more restricted sense: In theology, spiritual perception of the invisible objects of religious veneration; a belief founded on such spiritual perception.
Serendipity and The Three Princes of Serendip.
I have a note about “deesterous”, but I have no idea what that means. What were we talking about? I think I wrote it down phonentically, but the search engine is telling me “dexterous”, but that is not it.
Also we were talking about “flapping around in affluence”. What was that all about? Lost to time?
We discussed the Spectacle. More reading may be required, particularly of Jean Baudrillard.
The string theory guy is Michio Kaku. I’m worried he might be a crank. Or maybe he is brilliant. Who could say. I watched a video of him recently: Michio Kaku | Quantum Supremacy | Talks at Google.
AI and the paperclip problem is described here. The problem is if you design an AI to make paperclips it might destroy civilization. Because, to begin with, it might sense that humans might try to turn it off, which would impede its ability to create paperclips, so it wipes out humanity and uses the atoms of our bodies to make paperclips… I mean, it is *very good* at making paperclips.
We mentioned Experimental Jet Set, Trash and No Star. Classic. On the web here.
The Chillout Sessions began back in 2001. They don’t make ’em like they used to.
The concept of enshittification is explained by Cory Doctorow in Tiktok’s enshittification.
I mentioned about Musk feigning thought in an interview I watched recently. Check this out. He totally pretends to think deeply about the question! It’s awful to watch, like bad acting!
I mentioned the video game Descent. I remember playing it back in the nineties, it was so cool! I think there is Descent, Descent II, and Decent 3. Apparently I can get them all on Steam. Gonna try that. Want to get myself a good joystick to go with them, maybe this Logitech G 4021846 H.O.T.A.S. RGB Throttle and Stick Controller X56.
You asked what brings me joy, it is this:
Love you brother. Can’t wait to see you again soon. <3
ATTINY85
Searching for ATTINY85 over on AliExpress and sorting by popularity renders some interesting results.
