I tried finding Hidden Gems on AliExpress & got NASA Technology?! (Part 8)

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 Displate for sponsoring this video

The GPS tracker isn't actually using a GPS chip, it triangulates its position from 2G antennas.

I had to force myself to stop buying random electrical components from china, so I love living vicariously through these videos

Yeah, my rucksack has NASA technology on it too. It's called velcro

UV resin is the best for glueing coperwire to glass or glass to glass. You could in theory use super glue, but that tends to break and affects the glass surface. The downside of UV resin is that UV light needs to penetrate to cure the glue or it will forever be a liquid. Trying to glue 2 metal pieces with UV-resin is definitely a no go 😂

UV Glue is actually very good for sticking new copper traces to a PCB. Like the UV Mask that is regularly used. The only caveat is that you need to glue the copper trace from above by covering it and the surrounding area, not expect it to bind below the trace.

Finally another Aliexpress hidden gem video. Thanks! Please continue this series!

That GPS thingy isn't really a GPS. It takes positions from the cell towers, this way they can achieve a reasonable battery life, and bad precision. The real satellite GPS reception requires a lot more power and the trackers are seriously bulky because of that.

[faridfarrokhnia]

it's my understanding that the best practice to use uv resin glue it's with transparent objects so uv light actually can cure resin or simply using it in the surface like protecting pcb pad or something. thanks for the video.

The UV resin is still very useful as a fast and reliable filler material, and sealant. If you need to fill a misdrilled hole or partially seal the corners of a box, it works pretty good, specially cause it’s harder than hot glue but “dries” in about the same time.

[thesage]

Aw that UV resin is useful for lots of things other than gluing. Great for coating things. I don’t think that particular bottle was actually adhesive, just resin.

[guillaumep.]

The UV resin is not a glue. it is used to protect things, like waterproofing PCB.

One of my friends got me that oscilloscope for Christmas and it's worked great along with a USB logic analyzer. I think the main problem with the frequency detection is it uses the trigger threshold as the period counter, so you have to set that manually. If the threshold isn't within the waveform, it won't report a frequency

[macromage]

the mini oscilloscope is great for home audio people like me who wanna tune our amps and speakers properly plus also scientifically work out when and if out headunits/amps are distorting at certain volume levels

[jonmayer]

Wow, the cell phone boosters bring me back to the early 2000s. These things used to be everywhere from big box stores to mall kiosks.

When I bought a similar GPS tracker like 13 years ago, (it has the same functions as this one) it was advertised as a tracker for your car. And that is why I bought it.. So you hade it in the car, connected to the ignition, and then you can track the car if it gets stolen, and also listen to the thiefs.

[Frostfly]

UV risen is super common stuff in hobbies like Model building and mini painting. Shows up in some jewelry work too. not usually used as a glue though.

[MKDS]

Now put the OLED screen on the oscilloscope, add the GPS tracker to never lose it, glue the signal boosters to the GPS tracker thanks to the UV glue so its GPS signal is better and attach the air freshener so it's the freshest product in your home :)

Only 30 kg pulling force? You need to drink more milk.

[partytempo]

They STILL are peddling antenna booster stickers?? I remember seeing those 20+ years ago for nokia brick phones 😂

It's UV resin, it's NOT glue! It's used for example if you want to protect a surface. I use it on flies for fly fishing, makes a lovely thought coating on the smaller delicate parts. Works pretty well too, quite tought when cured
