In this video we will be having a closer look at 7 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 Elektor for sponsoring this video!

i am actually very interested in the windmill, maybe a follow up video where you see what is wrong with it or try to improve it?

[advisedpotato]

Hope this turns into a regular seires! Im loving it so far

Would love to see you modifying that wind generator to get it to work.

A tip re battery spot welding: When there is a gap in the metal strip touching the cell as seen around 8:45, you should weld across the gap.
The gap makes the path of least resistance pass through the battery cap instead of through the strip, this results in more energy being used to make the required weld and less being lost to heating the strip.

Great content. Keep up the good work.

Maybe re-purpose the Schumann coil as a coffee mug warmer. Just have to put a current limited supply through it... being careful not to let it get too hot and de-laminate.

7:42 to melt the enamel on magnet wire you always want to start at the tip, passing the tip of the wire through a very hot blob of solder on the tip of your iron. You start at the tip because there will always be some exposed metal there from when you cut it, and thus the heat will get in through that end and the solder can "lift" the enamel up as it burns/melts.

can you make this a regular series this was fun to watch!

I got one of those USB C cables with the power meter in the connector after seeing on your channel. I was super skeptical after seeing the $4 price free shipping, but I've been using it every day now and it's really good! The connectors are even anodized aluminium and the power reading is pretty accurate. Great recommendation!

Great idea for a series! I think many of us have been the victim of misleading advertising on AliExpess - but also had some gems!

[harriehausenman]

Great format, highly compatible with YT. I would love to see more, even with some more quirky and maybe obviously bad stuff. BigClive & Co are quite successful with it and you also have your own humor and approach to testing. 🤗

These series are amazing, and I would love to see more! I know its most definitely expensive to collect, order, ship and all that stuff, but maybe a bit more often would be nice to see. Keep it up!

[Hoopty_Poopty]

This series is so great for hobbiests because AliExpress is the first place to go for cheap electronics

[RestoreTechnique]

Nice to see other people buying random stuff from AliExpress. Shame the wind power didn't work

[supersosiska]

Wow, I was expecting garbage like toddler coloring books or knockoff usb drives.

But this guy is killing it with DiY components! Bravo!

[DirkFedermann]

Thanks for testing the battery welder. I was looking at it a couple of weeks ago and was like "maybe... maybe not". But it seems to be ok.

'Melt the varnish' is somewhat difficult to do. You'll probably get better results if you get a small file, or tiny bit of fine sandpaper on a stick or skewer. Then just break through the varnish with that before soldering.
I've done quite a bit of similar soldering, but I bought a large spool of wire with a nylon coating, so melt through is much easier. Even with that I still prefer scratching through with a file or sandpaper.

[JustPyroYT]

Please Continue this Series! I really like it! 👍

Quality contents here dude, make it a regular series because there are a lot of undiscovered gems on Aliexpress

8:20 I build a spot welder/resistance welder using a microwave oven transformer and a dimmer circuit from a vacuumcleaner to be able to tone down the device which is unchecked capable of pumping out over 1000 Amps of current (at 1, 7Volts)

The Schumann coil is used by musicians. Some claim it balances the energies in buildings but our brains are attuned to the frequency and it's the 'sound of silence' which we experience in nature.
