Two methods to reboot an iPhone, from my friend CK:
- hold down volume-up + power for 10 seconds
- volume up button, 1 second later: volume down button, 1 second later hold power button
Force reboot on iPhone

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.

Life time supply of zip ties
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.
Switch rack
I made a rack for my network switches out of old coat hangers and craft sticks.
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.

ENGINEER PA-09 Crimping Tool notes |
Let’s go shopping!
UV light
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!
Testing CMOS cell battery
I was watching Computers running very slow, long boot time, unresponsive in windows. Let’s fix it. and Richard said that if your CMOS battery reads less than 3V then you should replace it.
Bodge wire
Thanks to my mate Bruce from Branchus Creations and his wire size suggestions I got a bunch of bodge wire for doing PCB repairs, being 1KG Enameled Copper Winding Wire 0.05 0.06 0.1 0.13 0.2 0.4 0.8 0.5mm 0.65 1.0 1.4 1.3mm Cable Magnet Wire Winding Wire Coil red. I got:
- 0.07mm (back)
- 0.16mm (front left)
- 0.31mm (front right)
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.
