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!

wisecoco has interesting screens but they are always crazy expensive
if the display touch was not working properly at the edges then I personallly would not consider that seller or stock from seller good to be recommmended but then I am not great scott. 😉. 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. Anyways as usual always nice to see this series i do like the tiny oscilloscope useful. THanks for this one and good luck 👍 for future ones.
This comment is from 6 days ago...
i recently also had the same problems with not being able to turn the screen, in the end i just transformed the app i made in the browser 😅
PS: even if you can transform the screen (which isnst too hard) then also transforming the touch didnt work in my case
The uv glue is very useful when repairing flex cable connectors....I can truly recommend it...very useful
The GPS tracker isn't actually using a GPS chip, it triangulates its position from 2G antennas.
That sucks
@@greatscottlabthere are better models that have gps like gf-09
Does 2G even exists anymore? Where I live G3 will be gone as well fairly soon.
Thanks. I just wanted to say it, too.
@@j.f.christ8421It depends on where you are. Some countries still rely on 2G for things like M2M (see Germany) while others like Japan don't use 2G anymore.
I had to force myself to stop buying random electrical components from china, so I love living vicariously through these videos
Haha
@@greatscottlab here's a big ask, It would be awesome if you could go hunting for a thermal imager that actually works properly. They're usually so expensive, that they don't seem worth purchasing.
@@tommyboi0👍
Infiray P2 PRO is extremely good and much better than Flir One PRO that is double the price, half the resolution and 2.4 times less frame rate and isn't totally shit 🤣
I have both and wish i never bought the flir one since it's been lots of issue with charging it, battery dead withing weeks, never works more than 5 minutes, doesn't work on 4 years or older phones since they end the app support and flir support refuses to help.... The infiray just works always
He blows the cash so we don't have to!!!
Yeah, my rucksack has NASA technology on it too. It's called velcro
NASA did that? Good job I would say.
Call the Mark Rober!
@@greatscottlabNope, velcro fabric was inspired by burdock in the 40s after George mestral had a walk in Switzerland. This fella is just messing around.
Edit : It thus completes one advent of biomimicry.
That GPS tracker is a better use of NASA technology, or more accurately United States Air Force technology 😂
Yea do some research before posting bullshit online. NASA did not create or even come up with Velcro…. As stated below it was created by a Swiss engineer.
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 😂
@@p-4p I was thinking the same thing but I might try the copper trace option.
The other day I got what was known as industrial strength superglue. It was a bit pricy compared to the normal stuff, but the bond is incredible.
Trying to glue 2 metal pieces was a no brain move
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.
There is metall glue outside but this wont wkrk
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.
I thought the same, but the product does not meet what was advertised when buying it, so its ok to give it a negative.
I would think that it could be useful, but only in very specific use cases, where you can actually shine the UV on a significant part of the area that you are trying to glue.
Yeah, seems like it might be useful as a conformal coating, too. I might also find use for it when doing manual rework of 3d prints.
Not really much of a glue, but it does have some uses.
Cola uv não precisa de uv, se você usa em objeto opaco como a uv vai agir na parte mais interna da junção?
I wish I knew where to get the "Dental" grade resin. @@oasntet
Finally another Aliexpress hidden gem video. Thanks! Please continue this series!
Thanks, will do!
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.
Good to know. Thanks for the feedback.
Sportwatches have had same battery life the past 10 years while using GPS. Nowadays even 40+hours, and I would assume with way smaller batteries. But sure, if you are going to use the cellular anyways, it might be more efficient yet kinda useless.
@@greatscottlabThe more honest sellers advertise it as an LBS tracker ut it scams way too many people.
Considering that GPS position devices passively receive signals from satellites your statement is misleading and wrong. The only power needed is to do a bit of math.
Most of the power requirement in these sorts of devices is in using a cellular connection to communicate to another device. That requires a cellular transmitter which drains power.
@@HyviaVideoitaMansenlale40 hours is plenty for a wearable device but abysmal for a set and forget style tracking device
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.
That seems like a good idea.
Wondering how it works on glass
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
I used a mini oscilloscope to troubleshoot and diagnose a burnt injector driver chip on my car ECU. They are really great for automotive use, I wouldnt have been able to get a benchtop scope under my dashboard and I wouldn't want to get an expensive piece of equipment covered in grease and general filth.
@@JamesChurchill3 yeah thats 100% what these were designed for, work environments where they will get dirty but will still give you enough info information to be able to diagnose the problem
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.
I was going to say something similar. Those copper stickers have been around since the GSM days and have ALWAYS been the snake oil of cell phones.
Omigosh ! I remember walking through the mall and they were being sold everywhere.
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.
Idk about that resin in particular, but I've had good luck using UV resin to repair small cracks and chips in car windshields. Not always the prettiest thing, but it keeps the crack from spreading and me from having to get a new windshield
The UV resin is not a glue. it is used to protect things, like waterproofing PCB.
There is actually UV glue available, and it is really good. It doesn't get completely hard like the resin, but remains some elasticity. Costs 25 Euro for a small bottle though.
@@graealexthat's literally just flexible UV resin used in 3d printers. Somewhere around 30$ for a 1kg bottle.
@@MaxC_1 No, it's not. And UV glue for glass and acrylics has been around for quite some time before resin printers were a thing. But resin for printers, even the flexible stuff, doesn't really adhere to most materials.
3D printing resin by design cures only in thin films, depending on resin it can be as low as 70-100um or even lower for high precision resins.
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.
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
From observing the video, when the waveform didn’t “sync” on the scope, and it kept moving, that was when it couldn’t give a frequency reading. Which seems to be due to exactly as you described.
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.
Need to make sure they are accurate though. Some just use cell tower triangulation like the one in this video, which isn't useful enough for most situations.
Also I hear that with car theft it occurs so quickly that law enforcement typically acts too slow to be able to catch it, because the vehicles get shipped off to another city quickly, then to a port, then to another country. 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.
That Oscilliscope is a great find!
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
Fully agree!
Yes, but the product does not meet what was advertised when buying it, so its ok to give it a negative.
They STILL are peddling antenna booster stickers?? I remember seeing those 20+ years ago for nokia brick phones 😂
And the exact same stickers are often sold by the same manufacturer for protecting you from harmful cellphone radiation, too!
Yes, the best (or worst) were the ones with flashing LEDs that would blink every time the user received a call. Although If I remember correctly those were sold as protection from harmful radiation.
The best (in the worst way) ones are the "anti-radiation" or "negative ion" stickers that are often packaged to protect you against the "harmful effects" of cellular technology (most recently 5g). At best the stickers do nothing, since if they worked as advertised you wouldn't be able to make phone calls. However, at worst some of these stickers have thorium or other radioactive products in them as their method of creating "negative ions." So hey, lets protect you from radiation by putting radioactive material on your phone!
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.
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 :)
You forgot it's a freshener that keeps your windows from frosting up. :D
UV resin only works well with transparent objects- why the heck do they market it as glue
Money I would assume....
i think they could make more money off of it if they marketed it as an art material
It’s used as an adhesive in a lot of crafts and jewellery making because it’s crystal clear and bonds almost instantly when the UV light hits it. You just can’t sandwich it like a contact adhesive or epoxy.
yes but then it should still be sold as an art/jewelery medium
@@johnlombardo Yeah, it's great for that. Everything else takes 24 hours for full cure. I was bemused seeing it advertised on TV as being able to instantly bond anything a few years back.
The resin is amazing tacking wires down and potting components
UV Resin is for optical bonding, not just gluing stuff together :) - Eg, Glass screen covers like on mobile phones, it really relies on the whole surface area where there is resin being exposed optically (like behind glass) and is used due to its clear optical property over say that 2 part resin which is cloudy/off colour. 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.
Excellent video, we really need more test like this. I was really happy to watch it.
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).
I’ve used a more quality version of that UV glue, and it works great if you do thin layers and use the light after each layer.
Yaaay, you did get around to testing one of the cheap scopes on Ali. I remember leaving a comment under on of your previous vids asking about them. I needed a cheap scope with basic functions, and this seems to be just the thing I was looking for.
No matter how repetitive this series may seem, do not stop it. This is very enjoyable to watch :)
I've found UV resin to be useful not as a glue, but as a protective covering that's still somewhat transparent
technically, a lotta things we use nowadays was first designed by the US Military or NASA for their own internal benefit. The internet comes to mind.
So they are not wrong
Well...true
NASA did not invent the internet. Vint Cerf and Bob Kahn are credited with "inventing" the internet, but more importantly, TCP/IP, whilst researching at UCLA.
I'm instantly buying that scope, really useful to have a small portable one around, can already think of a use, which is setting car amplifier gains, without carrying around a bulky scope and running an extention cord to it
I have a handheld combined multimeter, oscilloscope, and basic function generator; with probes and cables it was maybe $100. Comes with an 18650 cell as well. I already have a full-sized scope, but the portability is great. Brand is Owon.
that touch screen looks absolutely amazing, and has so much potential for projects, you considered it being so thin a downside but i would argue that it is actually a huge benefit, it is not meant to be used just laying on the table by itself. hell, i would add an aluminium back plate and use it as a drawing pad for image design
also, uv resin is not meant to be used as an adhesive, its meant to be a protective layer, mask for circuit boards or other "over the surface" applications.
I love this series. The mini oscilloscope is what I have always wanted, and the OLED might be handy in the future (klipper screen for my 3d printer, if it works with the RPi)
We use UV cure glue in watchmaking for fitting watch crystals, as it cures quickly and it dries clear. I had a few aliexpress bargains that didn't please me - such as a plant moisture meter that when immersed in a glass of water registered "moist" - so I asked for a refund and submitted a video, got the refund within an hour. Thanks for the lessons, enjoying this series.
That is by far my most favorite youtube series! Thank you Scott :-D
I'm planning to add that little oscilloscope to a larger experimental tool I'm designing. Glad to see it's not junk.
The UV resin stuff is used a lot with Electronics for holding "bodge wires" to a PCB or covering an exposed area after modification. Very useful stuff.
i love all of the Hidden Gems on AliExpress videos love to cee more
and keep up the good work
keep them coming pls, im loving the series
For PETG nothing beats welding it with dichloromethane tbh
Unfortunately you're not legally able to buy it in many countries, the UK for example, unless you're a registered professional. That's not to say you *can't* buy it, just that it's regulated. I mean, you can buy anything from the right place. 😂
@@GothBoyUK Hmyeah, fair enough. I'm in The Netherlands. Electric scooters are illegal. Can't have a catapult and baby jeebus forbid you defend yourself from a burglar... but drugs, DCM, etc? No problem! 🙄
An alternative is using ABS or ASA if you're planning to solvent weld parts, they have some downsides compared to PETG but have the advantage of being soluble in acetone rather than needing more hardcore stuff like DCM
Heck, velcro and cordless power tools are NASA technology. NASA spinoffs are everywhere in our society. Who kickstarted the mass production of integrated circuits? That would be NASA.
That cordless power tool story has gotten a little convoluted over the years. The NASA contribution was the cordless impact driver/drill. The impact method of tightening bolts greatly reduced the torque that had to be counteracted by an astronaut in weightlessness.
NASA didn't invent the Velcro though
*Shows pan*
This uses NASA technology!
touch screen problems might actually be windows problem : sometimes you need to "setup screen for touch input" and press the touch screen, especially with multiple output monitors. Also sometimes again after changing resolution outputs windows can get confused about touch screen location and resolution
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.
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...
Thanks for the upload. I love it when you do these, because their informative and fun and also because I order from Aliexpress too. 🎉
Glad you like them!
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 UV adhesive might be good for clear polycarbonate, plexiglass, and glass, etc
It's not glue, it's resin. There IS special UV glue for glass and other transparent stuff, though. But it's pretty expensive.
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.
im sure you will use the uvresin in the future, its amazing to protect circuits from water and outside weather, or just instead of conformal coating to hold some small wire down after you solder it.
Did not think about that. maybe I should also test it for that purpose. Thanks.
5 minute epoxy works just as well and cheaper, available everywhere for pennies, and cures chemically.
UV resin adhesive is excellent with electronics! I use it when I want to strengthen soldered wire connections or join LED strips together. Waterproofing is a bonus. Just don’t let it get between parts that the UV light can’t reach.
Exactly, you have minutes to sort your epoxy jib.uv resin gives you forever @@AaronHendu
I use uv resin with my translucent resin prints and it works well for my projects. When experimenting with pigments and dyes, the pigments reduced the uv penetration so I left the part outside on a sunny day and that did the trick
Love this Aliexpress series
we use uv glue to bond nozzle for vacuum attachment to glass plate in pcb uv exposure machine.
The UV glue may still be useful for improvsed tooth fillings!😄
jesus xd
we use uv resin for fly tying, it's not a great glue, but it makes a decent shell for certain things... iit also very useful for fixturing things in an exact position, because of the instant cure. after that you can then use a stronger glue etc
7:43 that's the devil laughing 😂
Huh, I honestly wasn't expecting to see you review the exact same oscilloscope I bought last year. It's good to hear it has your approval for basic projects!
About the phone signal booster - Its main function is to maintain better connectivity, not speed. Speed could also be limited by carrier or phone but signal strength and overall better stability is what it's all about
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
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.
I HAVE ALWAYS LOVED YOUR VOICE AND VIDEOS AND ACCENT AND EVERYTHING YOU TEACH US -- THANK YOU VERY MUCH!!!
I use UV glue to hold wires to the circuit board after I have made modifications.
It isn't structural, easier than heating hot glue.
Terrific video (as usual) , I really liked the oled display review. This type of video is always appreciated by me, please continue. Thanks!
Thanks, will do!
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.
Thank you for leaving in the sound from the glue tests :)
Great job..i Wait for Hiden Gems all time...
I used exact same screen with Rpi3 and various other SBCs. You can make it work. Just contact the manufacturer and they give you a file what to change and it starts fully working!
I still have a board around where I have exactly that modifications - just not sure where. Very good screen but I wish the price would be better. I have used it in projects.
Oh hey, I bought that exact brand of mini oscilloscope on Amazon for doing some waveform analysis on a synthesizer project! I also find the interface to be a little clunky, but it's *very* usable if you don't need to work on very high frequencies, and the auto-ranging works pretty well in my experience. I got the one with a battery so I can use it fully isolated, for I think less than $30 US.
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
Love the series!
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.
The UV glue would be great for acrylic parts assembly.
I once saw a video about phone screens, where you sometimes need to bend the flat cable backwards so that its metal part touches the back of the display, and then secure it with an adhesive, for proper grounding, and this could improve the touchscreen. I have no idea if it's actually a thing, nor if it would help with your display, but I think it could be worth a try, if you do it very carefully.
I've been considering one of these cheap oscilloscopes but the 2ch version. Glad to see it can be useful and for the price its a good
That UV resin glue works best for stabilizing and holding delicate connectors on pcbs.
That UV glue might be good for holding wires down. Basically any application where you can expose all of it to the UV light.
Love this series....cheers
Another great AE products review. Thanks. If you do find a good GPS tracker, please share the details. UV activated adhesives are really only useful when bonding clear or translucent materials. As you found, if the light doesn't reach any of the adhesive the bond will be compromised.
I love these series!!!
UV glue is used to secure ceramic crowns. Enough light gets through to cure the glue. It should work with translucent plastic, glass, and ceramics.
Nice video, thanks for sharing. The mini oscilloscope is interesting, a good video idea is to make a comparison between entry level scopes for makers?
That OLED screen is pretty awesome. I like the idea that these are starting to trickle down and that there seem to be controllers for them. I look forward to the potential for retro console replacement screens using these at some point in the future, like for gameboy/GBA/DS/3DS/PSP. The IPS ones supposedly look nice, but these would really truly be the ultimate especially for DS/3DS/PSP.
Fascinating! Thanks a bunch, dude! 😃
The mini oscilloscope is on my list!
Stay safe there with your family! 🖖😊
Uv resin is mainly used for resin crafts, where the uv light can actually get to the uv resin
The metal test pieces will bond better with the epoxy and the hot glue if the mating surfaces are rough instead of smooth.
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.
I've been curious about those little oscilloscopes for a while, but always written them off as being junk. Its pretty impressive to see that they actually work that well for the price! I might pick one up as a portable scope, it seems like a pretty good solution
I use UV glue with 3D prints using transparent filament. Works really well
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.
The uv resin is actually one of my favourite product, but it is definitely not a glue, I don't know if marketing it as a glue is a mistake or intentional. It works perfectly as a filler or a moulding resin, it reproduces surface details very well, and most importantly it releases from most surfaces easily.
Never thought of buying a little screen before. Interesting!
Finally another chapter, love this series.
I know that require a lot of money cz u need to buy everything xD, but's rlly interesting!
I suspect those "gps" trackers may actually just be using cell-sites for location, not real GPS
Ooh! I love UV glue/resin! I mostly use it for conformal coating or protecting solder joints. It’s actually not that great as glue. lol.
I think UV resin makes most sense as a coating or a stabilizer for parts that otherwise are in danger of being ripped off again.
Considering epoxy: You can get variants like 5 minute epoxy or 20 minute epoxy which cures in no time. I love this stuff. It can also be colored using simple airbrush acrylic colors, for example to make black epoxy to prevent light bleeds (for modelling stuff). Or mix in cotton flocks to make it thicker or use it as filler.
When you used the UV cured glue between the opaque wood and metal I real life facepalmed.
Thanks 👍
I friggin love your pronunciation of "glue". I'm gonna say it like that from now on
5:12 This is GSM antenna. This "tracker" not included GPS module. Only GSM position.
Tysm I needed a ociloscope so much its cheaper and not a bad diy one
