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.
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.

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:

I just finished recording a video for In The Lab With Jay Jay wherein I install some bodge wires using my recently learned techniques. Below is the finished result. It’s actually three bodge wires joined together. A small one (0.07mm, 0.003″) from 28A to 21B, a medium one (0.16mm, 0.006″) from 21B to 17A, and a big one (0.31mm, 0.012″) from 17A to 14B. The job was finished with some red solder mask. I will have the video up shortly!
It would have been more convenient for me if the 0.07mm wire had have been on a smaller roll like the other two, but we can’t have everything. I’ve been thinking I might get some sort of wire rack, but I’m not sure where I would keep it.
I wasn’t sure exactly how I would go about cleaning enamel off the wire for soldering, so I asked ChatGPT, which gave me a number of options:
Mechanical stripping
Thermal stripping
Chemical stripping
I think what I will actually try is just tinning the ends with my soldering iron and some fresh solder and see if that will burn off just a little bit of enamel on the tips, leaving me with a tinned wire I can easily solder into place.
