I tried finding Hidden Gems on AliExpress AGAIN! (Part 11)

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!

since this is part 11, can we do a compiled video of 10 parts showing only thums up products. that will be very usefull since every good thing will be in one place and can be done every 10 parts

Glue and paint, makes you the welder you ain't 😂

[FranciumEater]

You only applied glue on the surface around the joint, not on the area of contact which probably made the joint much weaker

With the torque wrench, use caution and follow best practices. The beeping kind can easily overtorque something compared to the click-type. Also, you cannot accurately check the torque of a bolt that is already torqued down because of static friction (or stiction). So I'd say it's great for your application where torque isn't critical, but if you start getting into areas like automotive, where torque can really start to matter, do your research. There's a great youtube channel that properly tests torque wrenches and torque myths.

The laser level still looks kind of nice to me. I've been in a situation where I just wanted to align things along a line that isn't level to the ground, and with this, you can also see the exact angle that you're aiming towards, at the same time.

the touch sensor is useful for switching things in waterproof housings...what is the idle current draw though?

"Bada bing bada boom!" Sonny Corleone was reincarnated as a German electronics content creator, who knew?

2:50 This description should be interpreted as a ‘substitute for welding’, not that it should be used in the same way. Adhesive requires surface contact on both sides, the more the better.
The logic behind some Aliexpress descriptions is more than questionable.

3:46 Don't we all love Chenglish? XD

so I have used that same UHU epoxy and that stuff is amazing. It is strong, it hardens in a day, it sticks to basically anything except polypropylene and teflon (expected)
But it doesn't fully cure unless you bake it at 200C
If you bake it for 5-10 minutes at 200C it'll be MUCH stronger than at room temperature and it'll cure faster of course
UHU has a curing chart with temperature, time and strength on it

By far the strongest "metal glue" is JB weld original. It's very slow but very strong.

By coincidence, I tried to do a job with the 'laser thingy' this morning and I have to concur, for the price the build quality and amount of functionality is stunning. But it is not very practical or accurate, and I quickly reverted to a simple spirit level!

Please note lifetime warranty doesn't mean for your lifetime it means for the expected lifetime of the product so would probably be 7 to 10 years, read the legalize that came with it to see what "lifetime" actually means.

That metal repair glue looks similar to JB Weld in the US.

2:28 You forgot the ramen noodles, so it didn't last.

6:00 - be careful. The limiting factor for most MOSFETs is _not_ the rated current per se - it's the junction temperature. Those max currents are usually essentially "note that even if you somehow keep the junction temperature within limits, you _still_ shouldn't switch more than this current lest you potentially get local hotspots & thermal runaway".

Unfortunately, calculating if this is in spec for the FET is nontrivial for a PWM device, as it depends on the switching waveform.

[Pelican_t]

As someone who works with SMD components, the solder tweezers are really useful to me.

[cent]

You definitely over-torqued some of your bolts there. And for few of them the beeping was telling you that the 14nm was already reached....but was it at 45?

[RomanoPRODUCTION]

00:43 mandatory smile (tm) this one was very strong and quick!

[gfdggdfgdgf]

Top tip: an incredible glue is any cheap super glue combined with baking soda. Strong as a rock, dries instantly, you can sand and drill it easily.
