For me atleast functionality should be 100% atleast for a produ t to be called working , build quality is next wheich as you said was delicate so is totally user dependant, cosmetics part is last, but then also comes value for money especially whe nyou buy kits unlike a ready prodcuts. If the kits are already costly then it will end up like raspberry pi which are no more diy option. Personal choice may be.

There's two caveats to this. One is that UV glue is generally considered super toxic. Don't use it on anything food related. It's also a known allergic sensitizer, so you MUST use gloves when using it, and wash everything after it's cured. Also, almost ALL UV glue sold now today is acrylate based. The UV inhibitors are also temperature sensitive. So if you heat it to about 180-200 C it will spontaneously cure without UV.

Not to say that it's futile to try though; it's not expensive to use these sort of things. Presumably only like 5 dollars a month or so if you get a super cheap data plan.

You can also use it as a form of 'conformal coating' if you wanted, but there are cheaper alternatives like clear acrylic nail polish to do that.

As you've found, the UV adhesives don't work at all between two closely contacting surfaces, especially opaque ones, as the glue cannot be cured. I have found it quite useful, though, for building up or filling in surfaces where the glue remains accessible. I use it regularly for things like tacking down bodge wires on circuit boards, filling gaps or holes, building strain relief on custom connectors and adapters (layer, cure with light, layer some more) or for mounting new/added connectors into housings. As long as the glue has sufficient surface area on the parts and remains exposed so it can cure, it can fillet quite effectively between two surfaces and provide a fairly solid bond, and it's way quicker to work with than hot glue while providing a somewhat stiffer and more rigid end result (sometimes desirable).

the "gps" device only uses triangulation (oh i see others have said it as well), but you could have seen the lack of any gps components as well

The reason why hot glue was that bad in your test with the metal pieces is likely that you didn't heat up the parts before gluing. Actually hot glue can be surprisingly strong even for metal. Maybe try again and heat up the parts using a heat gun.

It's not glue, it's resin. There IS special UV glue for glass and other transparent stuff, though. But it's pretty expensive.

UV resin (glue) is really good for fast and precise adhesion, but utter useless for bonding big opaque parts. I have repaired wader boots, inflatable boats, waterproofed electronics and containers, fixed rips and lots of other things, where UV-light can harden the resin without it being covered.

Bro they have been selling those antenna “signal boosters” since the Nokia days. And they were like 30 bucks! I’m so happy to see that you have scientifically disproved it.

That is by far my most favorite youtube series! Thank you Scott :-D

We use a lot of UV cured glues at work, and these do work well. Once the cross linking starts to happen near the edge it quickly propagates to the non visible polymer. It's all in the chemistry.

JB weld makes a cheap UV active adhesive that has self curing properties, so occluded areas can also bond. It sets up instantly with UV, and results in a material like plastic with the adherence of super glue. I've been consistently blown away by it, the other UV resins I've tried are more useful as coatings than adhesives.

Hey Scott, about UV glue, what is more interesting is solder mask, that harden with UV. It's very nice for DIYers that want to fix circuit board and isolate again after a mod...

Love this Aliexpress series

For hot glue on metal you need to preheat the metal and clean it. Then it sticks much better. I guess the cold metal piece cools the glue so quickly it can't make intimate contact with the surface.

Clear UV resin isn't for gluing. It's for filling cracks and voids in transparent items.

UV resin has many niche applications. I find it works pretty well when you need to glob material onto the outside of something to immobilize it. I've used it to keep a cracked phone glass from becoming a problem, to keep a M-F antenna adapter through a PVC cap from moving around, preventing loose bits on pcb boards from becoming fallen off bits, etc. It really benefits from having a well prepped surface, roughed up and cleaned with acetone (if possible). It doesn't work so well when mating 2 surfaces together, but I've been able to get a limited amount of obscured resin to cure by setting it out in the sun for a while. IMO, that's the best way to cure resin -- there's few UV sources better than direct sunlight! It's also good at reinforcing wire soldered to pcb pads and those tiny screw terminals you frequently find on voltage convertors and diy connector ends. Just screw in your wires and glob it up with resin and you've got a significantly more reliable connection

I've been a sub for a couple of years now, but, I'm just saying that I check your channel way more often just for this series! Man it's great

I use the clear UV resin instead of this green stuff (german Lötstopplack) to protect traces or soldering on PCBs. Its very useful, but you cant glue parts together. Everything of the resin must be cured with UV. The UV must be go everywhere. Therefore best: clear, only on top surfaces.

For the oscilloscope, I really recommend to skip these 15-20 € DIY ones, and really get the 40-50€ to 120 € range ones depending do you need one, or two probes and is there a need for more than 5-10 Mhz as in some processors and chips.

That “GPS” module manages to be both creepy and crappy for one low price! 😂

i love all of the Hidden Gems on AliExpress videos love to cee more and keep up the good work

5:12 This is GSM antenna. This "tracker" not included GPS module. Only GSM position.

I think the UV glue as you named is UV resine as written on the container, that is not a glue but a surface resine protection not to glue to objects together.

I do believe I've used both correctly in that, but I could always have been the wrong one.

This UV resin is not to be used as a glue and is to be used on circuit boards, as if a terminal breaks on the board you solder the spot and apply this resin so the wire doesn't come out.

That OLED screen most likely failed QC in some factory and got sold on AliExpress to make some money out of what would have been trash otherwise. As people often not return defective stuff on AliExpress, they make money with it. Even if someone returns it, they can still sell it again or throw it away without loosing money.

UV resin glue is great for applications on UV transparent materials or on surfaces. But zero use for deep UV opaque materials because it can't get the UV to activate beyond the surface.

Thank you for leaving in the sound from the glue tests :)

Putting a layer of UV glue on both surfaces then very quickly exposing and clamping them works but is a bit hap hazard. Good grade threadloc works well even if it takes a while to cure.

Uv resin is mainly used for resin crafts, where the uv light can actually get to the uv resin

That first item, the UFO with NASA technology, has a 3.9 rating on ali. A lot of reviews say that they haven't tried it yet, which makes me wonder why they left a review.
