In this video we will be having a closer look at 8 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!

Aliexpress takes anywhere between 4 weeks up to 4 months to deliver stuff to my house.
i love it, because 2 weeks after i order stuff, i completely forget about it, and then out of nowhere a new package arives every week for about a month (depending on how much you order).
it really feels like its christmass
I like your attitude. For me the packages should come in three days and if they don't I start getting impatient. But it feels really good to be able to order something you missed for a project and get on with it without waiting for too long.
Absolutely this. Especially after a few drinks, I buy myself the coolest stuff. And I've never had an issue getting a refund on poor quality or broken items.
especially if a ton of stuff that you ordered arrives in the same package, really feels like christmas!
I just ordered 36 separate items and then found out it was the first day of Chinese new year!
I wish I could leave a note with the parts reminding me what I intended to use them for!
The pump seems a sentrifugal pump. They never suck, they only push. You need a line wit no air in it, an u-shape to keep it always primed or a oneway valve to keep air getting into it from the output side (especially when the pump is off) after priming it. Any air in the pump will make it not pump.
lol been sick in bed but I got up so I could read text well enough to write nearly exactly this. This^^^^!! Well said.
Yes, a check valve will definitely work if the the pump is always filled with water, but I think it is a vane pump because you can see the input shaft is offset from the center of the casing.
A vane pump is potentially capable of sucking air, but it needs to be made with pretty good precision.
Not sure how he got it wrong
Did he think it was vacum generator?
Ofc it wont be able to make such suction for water to reach the top its a water pump not an air pump
I can get the same product locally but marketed as an oil pump...
Literally jumped into comments to make sure someone already wrote it xd
Just an FYI, The center hole of the Spy Detector, with the ring of LEDs is meant for detecting cameras. With those LEDs illuminated, look through the hole and look around the room, any camera lenses should reflect the light into your eye making them stand out against the background.
yep although these days cameras are often too tiny for it to work
You can find spiders in your yard similarly, shine a flashlight out and hold it up by your eye and you can see their eyes reflecting back.
[[FBI has left the chat]]
@@D1G1T4L1Z3D I'd rather not know they're watching me..
You know what else reflects bright red dot that looks exactly like a camera lens and could be except it ain't. Regular Screws, any plastic, especially plastic bins, ceramic, copper, metals generally, sparkling glitters clothing buttons, zippers, glass bottles, did I mention plastic bottles. The list goes on and on everyday items give the same exact impression. Now mix that with a constant ring only in your room. And RF and emf detectors confirming something? it ain't all in the head. But where the effing shiiit coming from.
Actually love this kind of episode...to check different tech on online with new idea
That is what I thought as well :-)
2 weeks in Germany, i lived in Brazil it took 2 months to recive an item, so i moved to France, and i used to recive in 2 to 3 weeks, now i am living in Sweden and takes 1 months sometimes more to recive , and the shipping is expensive..
Most of the things take a month to Germany in reality
@@NinoJoel U should looking for delivery from Poland/Germany. U can have in 7-8 day's.
Yes items are more expensive but faster, also remember always use a Credit card where u can get a charge back.
You should move to China there you could buy yourself instantly 😃
@@farhanafjal4183 they have big distribution center in Słubice (first city in Poland after crossing border with Germany)
I have been shopping in China for about 5 years now. At the begining, shipping to Germamy (be it from aliexpress, ebay, or bangood) took ~1,5 months. Nowadays, items often come only after 2 weeks.
But it varys A LOT.
I guess there's just not enough demand to ship to China from Sweden while China to Germany is likely very popular
The hand drawn diagrams are super satisfying. I usually hand draw my schematics before drawing them on solidworks and i spend entirely too much time trying to make them look perfect. No one will probably ever see them but i enjoy doing it that way. It’s a way to make my brain think a bit more and it “sticks” better in my memory also. I could watch you draw them out all day lol, thank you for the clear explanations when your doing it as well.
You have to admire his German precision even when hand drawing diagrams and schematics.
so true, if you've got the patience at that moment in time. I've had circuit boards manufactured out of impulse, only to realise I missed a component/trace etc when they arrive in the mail XD. Guess that's why they're called "prototypes"
@@johndododoe1411 Solidworks has an electrical engineering version.
@@anon_y_mousse the funny part about your comment is I’m also German. Well, I’m American, however, German ancestry. Not to mention I’ve spent most of my career working for German companies here in the states and abroad. It’s a natural fit for me lol
I do appreciate such episodes, wouldn't mind watching if this is turned into an actual series!
It's great that someone with your experience in electronics can analyze these for us. Would love to see more cheap electronics reviews.
Absolutely looking forward to more episodes of this. Aliexpress is full of gems but between the bad descriptions and millions of items, it's hard to find what is good and what is bad.
I like these kind of videos 👍 it's every time a surprise, what these products can deliver on quality and funny stories (like the one with the broken crank/handle 😂) looking forward to more of these Kind of Videos
Hopefully more to come 🙂
@@greatscottlab Yes, pls
same here!
Absolutely love this idea for videos, I frequently go to aliexpress and just go down the rabbit hole of different products and devices wondering what is good or bad! I would love to see more of these in the future!! :) Shipping times can be awful, but some of the halfway decent looking things would make up for that time in my mind, I sort of use it to get things I want but don't need in any specific timeframe and when they show up its like a surprise from my past self, bahaha.
Thanks for the feedback :-)
Nothing beats the Shrek masks there tho.
@@greatscottlab You're very welcome! I really enjoy all of your videos!!
@@Kalvinjj I have some different lists on AE for various categories, one of which is just for products with WILD long and bizarre names. I sometimes look through them just for some good laughs.
@@11danzizzle11 Reminds me too of a DC motor I was looking for a CNC drill and the description had something like "100w violence".
The auto translation is peak comedy in there.
Absolutely brilliant concept for a video. PLEASE make this an ongoing series!!!
That dodgy chainsaw attachment looks absolutely terrifying. :D
I wouldn't use it, you do need your fingers doing electronics, after all.
Having your hand so close to a chainsaw, even a small one such as this is not a good idea. You could end up looking like a happy tree friend. Stumpynubs did several videos on chainsaw grinder disks after getting injured by one.
@@carpespasm Although those disks are far more dangerous since they are all round and meant to be used on an angle grinder that's more powerful and faster than a drill. But yea this chainsaw looks like it doesn't have a good use case. You can outperform it with a good handsaw in every category, including physical effort 😂
That 5V/USB super capacitor buffer/filter will be useful for those USB solar panels. I have one, but it only works well under very clear sunny conditions.
I love this kind of videos, i hope you make of this a serie 👌
Will see how it performs. Hopefully good because I would love to do more :-) Lots more interesting stuff out there
@@greatscottlab Yes! Please make this a series!
I’m looking to get that Li-Ion charger board. Glad it worked out.
I was also looking at getting a charger + boost converter module (all in one IC solution).
I bought that one a few years ago and was not so happy. It did not convert the voltage level from 5v to 4.2v, instead it was pulsing 5V directly to the battery.
6:26 is there a competition to guess how many diseases you caught from that pond water? :D
50
this video is well needed
def worth doing a series on these products
Don't give up on the water pump, I have one like yours and it has helped me from time to time. Last time emptying a fuel tank while replacing a fuel pump and filling it back again.
I feel like it would work better with a length of hose on the other side, too.
This could spawn a whole separate channel, hope it gets enough attention for Mr. Scott to consider this.
Haha we will see😉
Techiesms or something similar test a random esp32 board's from sources like Ali Banggood etc.
One problem I have with AliExpress is I can't group products together for a smaller shipping fee when buying from the same store. It's always full fee for each item shipped, even when they actually send them together in one package that costs them the price of one of the shipping fees.
Ask for a refund. take pics of the parcel and request all but one shipping back.
@@stanneh1978 How do you mean ?
because the shipping fee is part of your items' cost lol...they inflate the shipping fee to lower the product listing price. Seems more attractive on the listing. To them I think it's by weight onto a huge freighter, so it doesn't really matter it's the same price (or close) for them.
PLEASE make this a series, this a GREAT idea Scott!
This is a great idea for future videos and I'm sure many people will appreciate it, please keep testing more products especially from solar / wind source renewable energy related products.
I love seeing you explore the strange products Ali has, but Damn! Those prices are cray cray
I bought that drill powered pump is $10aus or around 6.5euro from a local store here.
And 46euro for a 20w handcrake generator that was essentially just a motor? That was hard to stomach.
cray cray???????????????/ How old are you?
I genuinely feel you could create an entire second channel with more content like this! Really useful!
The electronic bits makes me miss the old days of Ebay, where you could hop on and buy like 5-10 pounds of mixed electronics for no money at all. I loved getting those because they were like little treasure troves of what you could get. Usually you'd just get the usual stuff or a few boards from something, sometimes you could get neat stuff like expensive ultra caps or fancy laser diodes someone thought was trash! Unfortunately, it's just a second-hand Amazon now...
Used to buy lots of odd stuff, mainly sold as gold tech scrap. It had a good chance of having unusual parts in it. ❤
I use Amazon to research stuff then buy it elsewhere..I boycott Amazon and most people should but the herd likes to be sheep.
The design is very human
I followed you since your first videos, it's amazing how your channel has grown!
Thanks for the great content!! :D
Piping plovers! The greatness of this channel keeps getting greater and greater!
I adore the motley salmagundi of products that only make sense in a unified review video from Great Scott!
AliExpress shipping indeed takes too long . . . but it is sometimes worth the wait!
With much appreciation.
I like these kind of "looking for gold in junk" kind of videos! 😄
That anti-spy device is very popular in China, ppl hide wireless (usually wifi) cameras in power sockets, ceiling fans, heat vents under wireless routers, behind IR window on TVs... in hotels and Airbnb to capture privacy videos and sell them online. Besides detecting wireless signals emitted by wireless cameras, with the LEDs turned on you can spot hidden cameras through the round window in the middle.
Love this series! Please keep up the good work. So many new products every month. So much potential.
Great video and brilliant to see you explaining how good items from Aliexpress are ! please do more of these videos as this one is excellent !! Thanks again.
As a habitual AliExpress browser, I love the concept of this video! This would be great as a recurring series! 👍🏻
I've watched your development over the years and it's amazing. I mostly became interested in your synthesizer step-by-steps and excellent explanations. Becoming visible, too, really improved your channel. I trust your acumen, so reviewing Ali Express (Geek, Wish, et.al.) is the PERFECT thing. You know they're watching this and hopefully improving their standards at least on the products you review in such excellent detail. Your narration is excellent, the script, the pen drawings (super good). I just want to tell you how much I love your channel and your output. Cheers! Jonathan in Seattle
Thank you so much😁
These sorts of videos are great, especially the electronic ones. The rather sketchy looking mechanical devices (that chainsaw) is scary looking. Can't wait for the next one.
Thanks, Scott! I didn't even know such kind of cutters even exists! Aliexpress owes you a great deal!!!
7:44 IP2312 awesomeness - TP boards are weak. This new board is a real gem in comparison. Amazon has them but at 4 to 10 times the price 😟
9:44 Could you repurpose the hand crank generator for pedal power, wind or water turbine? It seems ideal for that.
11:14 But .. but isn't the detector for remote locations where signal is sparse? In town it would be going off all the time? It probably does a running average of signal strength?
Signal detector for hotel room to detect secretly installed voyeur cameras
loved this episode, please more!
Would also like to have a guide on how to use lithium batteries safely with charging etc and how not to overdrain them etc.
I love these random gadget review videos, especially when you buy things that I was already putting on my wishlist. More, more!
I found your channel last week and I'm loving it, thanks for the good content!
Hi, I use the same drill powered water pump to empty the dregs out of my Hot Tub, I think the reason it didn't work for you was because your drill was on the lower speed and you need a higher rate of RPM, fyi, the height of my hot tub is approx foot and this pump works great for me - so I suggest you try your drill on a speed 2 (if your drill has this feature), but all the same I do enjoy your vids
There's a clutch switch on the top.
As someone who has basically zero budget, I love Aliexpress and I am always on the lookout for videos of some good finds there. Sure, you have to take practically EVERYTHING claimed in the listings with a heavy dose of salt as 99% of it all is fake, scam or the specs are highly exaggerated, but you definitely can find some good, useful stuff there. Also, even if you could find something similar here in Finland, it'd literally cost 6 (or more) times more -- and that's not an exaggeration!
I hope you do more digs through Aliexpress in the future.
Hey they don't usually lie. If they do you just prove it and get half your money back
@@crissto8591 Half? I've always gotten full refund, I don't accept anything less.
@@WereCatf that's for when I fix them and use them anyways
Keep up the good work: yours is a great initiative. Consumer product tests are important and make producers think twice when writing their product specifications.
I also love this idea for videos, and would love to see more of these in the future!! Thanks !!!
The hand crank generator works best with super capacitors!
I have seen other people add super capacitors to it and it appears to work far better....
As for the hydro generator, I believe that there are better versions which are all black in colour and rated for 12v output.... I would love to see you test one of those....
I wonder if it would be possible to rig up a better turbine for the hand crank and use that in place of the water generator...
@@eccentricthinker142 you are going to need a gearbox because you won't be able to turn the water generator by hand fast enough....
I'm sure that there are better versions available which are rated for a 12v output....
@@PeterMilanovski I meant the other way around, rig up a turbine to run the hand crank as a water generator.
There might be a torque problem though
@@eccentricthinker142 if it rains a lot where you are, then it shouldn't be a problem.... Or maybe there's a stream or river close by? Otherwise it's not going to work.
@@PeterMilanovski It's easy to get a lot of head from a stream, which can translate to more RPM with the right gearbox, but rain is just too unreliable for actual power generation in almost all cases.
Hence why the main use case was as a flow meter in the video.
I loved this episode!
The chainsaw gadget looks like an amputation just about to happen. I would bury that under some garbage to keep it from ever being used.
Love the video idea! keep it up, i am a long time aliexpress user but you showed me items that i have never seen
going to buy the drill jig saw
Haha glad you enjoyed the video :-)
This was fun and useful. I hope videos like this mitigate the trash problem at least little bit!
AliExpress banned in India😭😭
Sorry to hear that.....
@@greatscottlab Banggood too.
India's import taxes are 80%, which they just can't handle
@@bheeshmavasuprasad yep
@@greatscottlab Can you tell me which websites are banned in your country
Your handwriting and drawing are a joy to watch! Thanks.
Great idea, I would love more videos like this.
Great Video! I wouldn't mind a whole new series of these videos. I frequently get lost in the aliexpress realm of products and buy some stuff I can see myself using.
Really good video. Quick, to the point and entertaining. You should defo make more like this. 👍
I love this kind of video, please keep doing them!
I like this video concept, look forward to the next one!
I would love a board like @9:00 but with jumper pins to set cutoff voltage, and also jumpers to connect built-in resistors for current setting.
Then you could just move a couple jumpers and charge basically anything lithium based in a small package with no soldering and resistors.
A lot of people here in Brazil complain that delivery times are very long when ordering from China. However, it hasn't been uncommon for overseas purchases to arrive faster than some bought from local retailers, especially when using private couriers (instead of the Brazilian postal service). The average delivery time from Aliexpress purchases has been around 2-3 weeks (even though some may took waaaay longer), while I've had some local shipments that took over a freaking month to arrive.
This type of video was a lot of fun. Hope to see more like this.
Thank you for all your efforts in educating us.
That was great, Scott. That drill powered reciprocating saw was interesting!
I love how you explain these things. And it also helps me to improve my English 😅
This is a great series please keep them going.
love this one. would watch a series like it =)
Love it!...u shud make a series out of this
loved this episode more of these will be welcome
Love this kind of video! Not just some boring unboxing. Keep it coming. 10x like from me lol.
Thanks! Will do!
this content is so valuable bro, genuininely; thank you for making this!
Please keep doing these. Make this a series even!
Hi GreatScott,
Nice practical video ! I'm looking for a quality step-down DC-DC converter (accepting possibly 60V on input) and able to sustain continuous 3A use. I bought a lot a such converters (on ebay/ali) and was very disappointed with sturdiness. They were based on the XL6009/XL4015 chips. they were also supposed to self-regulate when overheating but most of the time, I found them lying with the PWM chip burnt...
If you have suggestions.... (thanks)
I love this concept! Keep it coming!
I used a similar drill pump to empty an old washing machine once that died. It's not as deep as your pit, but it had no problem pumping 24" deep and I suspect it could me much deeper. One important thing to know is they are only supposed to be used in one direction.
Nice! Looking foward for episode 2!!
Love these type of episodes!!
Thnx, fun watching, bought tons of stuff on ali with similar experience. Learnt to read product description and reviews extensively. Anyway, good video for me 😊
Good video :) Def want to see more videos like this in the future!
we love this kind of video, the jigsaw adapter seems really handy, and the prank generator looks very funny....
Hi Scott. I solved the heating of the old battery charger using a thermal pad and putting PCB on a big metal plate. It works like a charm.
One of my favorite thing to buy from aliexpress so far has been these boards for converting old laptop displays to hdmi monitors. Used quite a few of those and they don't cost much.
please make many more eps, this is awesome
ooh...definitely want to see your DIY or buy on the SuperCapacitor Cube!!!!
I understand the love/hate relationship with aliexpress. I ordered around $80 worth of ICs for a synth I was designing and none of the ICs arrived and on top of that I didn't get my $80 back. You really have to be careful when ordering because you may think you're ordering from a company who you have previously had a good experience ,but in reality is just an unrelated company using the branding of a company with a good reputation. That being said the thing I love about aliexpress is that it's a great place to find aftermarket/obsolete/vintage ICs and very specialized tools/ test sockets/adapters. I found some very nice test sockets that would have been costed an arm and a leg on amazon and some used vintage YM2203 sound generation chips that were completely unavailable on amazon or even digikey.
stuff i bought and liked - sata to usb3 converter, esp32, neodymium silk dome tweeters, lusyia dac, bt5.0 dongle for 1.99 ,android tv box, and tons and tons of class-d amps from 2x3w with BT... to wuzhi 2.1 (subwofer ) BT one.. and all of em are basically amazing
5:39 “~but ‘water’ I expect”. Lol
Pls do more of this videos, even a series would be cool, something like, testing random products that I've found on AliExpress
Good and informative, thanks
Bob

Awesome video! We want more of those!!!
I saw the 4s usb c PD board in your B-Rolle I have as well. My plan was to use it with a 5s Power tool battery. For that I changed the resistor as described in the product description. Unfortunately it only started to blink a five pattern.
Have you tried to change the cell configuration?
i loved this video, we need more like this one!
More to come hopefully :-)
Great topic for a video. I hope you consider making this a regular event on your channel (every 6-8 weeks maybe?)
Sooooo... couldn't you feed the water wheel power into the 5V SuperCapacitor Filter and use the output as a power supply for the water tracker project you mention? I've been considering pairing that water wheel with supercaps to power a RP2040 project... what are you thoughts?
I really like this new video type! You should do more of it
definitely looking forward to that wind turbine, i got one for camping but haven't had the chance to test it yet
I've been since August browsing Aliexpress for components and its amazing the amount and variety that there is.
I'd love to see some suggestions for a lipo battery charging and protection circuit if you can find any.
11:08 and of course, you simply power the hand drill with the output from the generator! Genius!
Brilliant, thanks for sharing
please make more videos like this, very useful!
Wow that super capacitor filter is what i really wanted for a long time, i might consider getting that.
I love the idea of this video. You can give in to buying crap you assume is crap, but are not sure. So we don't have to. You are taking one for the team, so to speak ;)
Very good and informative video, keep doing these!
