I tried finding Hidden Gems on AliExpress AGAIN! (Part 12)

You can get the featured products here: (affiliate links)

In this video we will be having a closer look at 6 different products I got from Aliexpress. Aliexpress is famous for featuring the newest products/ICs when it comes to electronics but finding those can be a bit difficult. So I tried finding the hidden Gems not only electronics related but in general what I think could be useful. Let's get started!

Thanks to JLCPCB for sponsoring this video.

14:32 Verdict

Sockets in light fittings were actually used before we got them on the walls!

The oscilloscope can do 46Mhz in High speed mode! By default its in normal mode for battery longevity, that's why you only get 35Mhz

I used to live in staff accommodation in a hotel. They would turn off the power sockets at 10PM every night to prevent gatherings/parties, so we hooked up an extension to the light socket. That socket adapter would have been very handy. 😆

Some time ago I had my gas water heater replaced, and in the toolbox of one of the workers, was a homemade bulb to socket adapter, made from soviet-era parts. When I asked him about it, he explained that he also does roof and attic repairs, and in my area, It's uncommon to have sockets in attic, but we usually have lights so he used it for some low power stuff

I love this series because I constantly stare at some weird electronic find on AliExpress contemplating life decisions.

If you have trouble reading small writing, a bright torch does wonders. The bright light shrinks your pupil, and that focuses your eye because the light beams converge at a single point. Looking through a pinhole does the same thing.

You can use battery internal resistance meters to measure any resistance; they are very accurate, up to 0.001 mOhms being a battery or not. And there are plenty on aliexpress

6:46 You couldn't find the current rating? The rating is currently that 4, 7 stars ;p

Those socket to outlet adapters are used a lot here in the US as an easy and cheap way to use LED shoplights in places where there are keyless bases, like garages or basements. You take the old, dim bulb out, screw that in, and plug in a higher output shoplight instead.

05:31 Places where there is no power socket, but a (not) used lamp is available, e.g. to install a WLAN repeater or WLan surveillance camera

[billcollins]

3:53 Where you using high speed mode? That steps up the frequency ceiling but at a cost of battery longevity. This scope has opened up a whole new world for me, as someone returning to the hobby on an extremely tight budget.

Addendum: I would love to see you do a tutorial on scopes like this for the beginner because I really appreciate your teaching style. Back in the 80s when I started, oscilloscopes where far outside my reach. And now that I'm returning to the hobby, I am learning to use them from scratch.

At the beginning of electrification, homes often only had electric lighting, but over time various electrical devices began to appear, such as radios, record players, irons, and vacuum cleaners, so out of need, splitters appeared that allowed for connecting not only a light bulb but also, for example, 2 other devices.

[Paln_drome]

The Oscilloscope / 3 in 1 tool at 1:53 seems very cool, but I’m mostly interested in the oscilloscope functionality with the rest being extras.

[AhmetYusufYatkin]

5:30 older days In my country, most public dormitories has socket ban for several reasons (Students uses dangerous materials or casual devices like kettle in dangerous ways or it is believed that telephones distract them and drops the succession rate among students) at those times, we were harvesting electricity from those light bulbs (ofc in dangerous way that most of the time there is open live wires). So this product was safer way to do that. I appreciated :)

[DerKlemm-Crafter]

0:20 This is how it was done before outlets were a thing. Weird yes, but the idea goes further back than outlets

[WouterVerbruggen]

The problem with that miliohmmeter is that, even with calibration, it's still a 2-point measurement. So if when the clamps slightly corrode the calibration is already wrong. And worse, the accuracy depends, possibly strongly, on how "well" a sample is clamped. But nevertheless, if the accuracy is good enough it seems like a nice tool for home use

[brumd]

Using light fittings as a socket was a life saver many times when travelling in India, where a lot of the cheaper hotel rooms have no sockets at all. The only way to recharge batteries.

[alexcrouse]

Light socket outlet adapters are extremely useful for upgrading your garage to led strips or fluorescent setups!

7:10 Kincony started doing this as a hobby and then started selling the electronic boards he designed for himself. Since he designs primarily for his own use, he uses high quality materials.

Not sure why one would want a digital jewelers loop except to take pictures, but a regular jewelers loop is great for identifying parts on a PCB.
