That last item is a boost converter only. It won't reduce voltage. They do sell buck/boost converters that look almost like this, but they will have two inductors (the black square thing). I use them in almost every project. If battery powered, it can hold the voltage constant as battery declines. In mains powered, it makes it so you can use any wall-wart power supply 3v, 6v, 12v, doesn't matter. Boost/Buck converter will hold voltage steady. Also note, amp capacity is closely related to size of inductor. For best capacity, pick the ones that say 220 or 330. One more thing (there always is) there is a ceramic filter capacitor and small inductor next to the positive output. Cheap ones omit this, and noise is terrible. Make sure it's there.
One important point - notice these are all those are WELCOME deals. You can only get ONE of those things for $1, see the crossed-out price for the REAL number. They also often don't include the shipping cost either.
You can trick this, use a new phone number if required (there are services for this, which allow you to get a 2nd one, otherwise use something like Visible free trial or Netzclub), throwaway debit card (Privacy, VIMPay, etc.) and intentionally misspelled address (Ali seems to differentiate between Av and Avenue for example, whereas a postal service should catch this), this has worked plenty of times for me. There are better deals than this however.
@@Hacktuberso what's the point of buying them on ali instead ebay?! eBay is much much more better! eBay is safer, you can pay via paypal and get a refund if something is wrong in short time. Ali is a scammer chinese reseller without any warranties (of receiving and refunding) with months-long shipping time (or 10x the cost of the item if you want a shorter time shipping) 1.000 thumbs up for eBay. 10.000 down for ali, temu etc: SCAMMERS!!!
It's a con. If I open the Aliexpress website I see all these WELCOME deals for $1 but as soon as I log in or click "Buy now" the price changes to something a lot more and they want to hit me with the same cost in shipping - especially if you live in a far-off country like I do.
I have had some issues with those cheap 555 Timer IC's. Some of them didn't work. I made a 555 IC tester with a couple of LED's, so I can test them out.
I enjoy adding mute and standby function to those little Pam modules. Simply remove the IV and cut 2traces under it and add jumpers from those pins too ground. Datasheet will back this up. Great little video
Dude. I thought this was a great video. I am always searching for my next electronics project and these cheap AliExpress components are very interesting and very useful. I appreciate that you took the time to go through these products and give us your take on it. Great job. You earned my subscription.
Hearing you express how satisfying having a lifetime supply of 555 sounds just like me. I like ordering lots of parts so I have plenty on hand, and not have to wait when I get an idea.
to be fair< I could have only dreamed of these gadgets being this affordable years ago. personally I think the amplifier boards and the step up/down one are really cool
@@Hacktuber Yes but seriously, if I would get a similar board here(which also comes from China 100%) they charge at minimum double, more likely the amp boards will be around 10 eur. Sad but true, but if they keep pricing stuff that high for more profit, I rather order them directly on Ali :)
what's REALLY Cool are these newfangled rechargeable batteries that output 1.5V with a much flatter discharge curve with USB C port for charging each cell.
I buy amplifier modules and components from AliExpress. Very good quality and price. Is the 555 chip good for making delay effects or amplifier circuits? Sockets are good especially when chips are cheap and can be interchanged with sockets for only rubles more ❤ Cents
Some items one cannot find documentation, like the various 'VI Curve Tracer' gadgets, with about 13 different configurations in the same enclosure, a few with display that would be unreadable for the job it is doing. Somehow the one I ended-up with had the display and no BNC connectors for a scope. That went back, returned for no docs. Then I found the same unit, but WITH the BNC scope connectors, for half the price, but still no docs. At least the packages from/through AliExpress are not stomped-on, like wish.CON's are half the time.
Have you considered adding the “huge” Bluetooth receiver to your tiny radio? Unfortunately, it would double its size. But maybe you could make it VERY thin…
I'm not sure what country you live in and maybe you've just had great luck getting the items you order but, I live in Arizona USA and every time I have ordered things it doesn't come for months and when it comes it's not what I ordered. Any suggestions on the way it's ordered or ??? There have been some things i'd like to try from your list !
Look for suppliers that have US based distribution points. Yes shipping from overseas takes a very long time so many suppliers stock their products in the US distribution bases.
The above comments are correct, but then can be more expensive. The idea is to be patient, I have waited for 2 months for things and forgot I ordered them. With ebay I have had only a couple of issues with Chinese sellers (and probably not seller related), so if you are patient then all good. I even pay more via ebay as I do not want the hassle of my bank account details with additional platforms. Unfortunately sellers have to jump to the next platform Fad, and sometimes You struggle to find things on ebay for a good price as too much work to be on all platforms I guess...
So happy to see you now at 1.3M subscribers. Quite incredible for a technical channel.!!! Well done. I've enjoyed your videos for years, and hope to continue enjoying years into the future.
The cheap USB Testers do not compensate for the Voltage they drop or the extra Current they draw running their own circuitry, especially their display, so V will always be a tad low and A high. buyer beware
@@Hacktuber probably because I think it wasent aliexpress fault it was a hacker that managed to hijack my google account! But I rather stay off aliexpress but one thing you should never buy their is ssd, external drives, HDD and SD cards as they are a scam!
What is your favorite Gadget and why?,please comment below thank you
The Arduino board would be my favourite, it may get me to learn to program a micro controller at that cheap price.
The display #8. I wonder if it is touch-sensitive and would even pay a dollar more for that feature 😉
the boost converter. Just to reverse engineer it.
I had to laugh out loud when i counted your 555 chips in the foam. From the 100 you ordered there are 99 left :)
We planning to made home made oreshniks...good value for money considering they can be useful in hypersonics armaments😂

I stopped watching the video at that point

"wow, this is satisfying" while stroking a bunch of 555 chips 😁. True passion, Hacktuber! May your channel thrive.
Thank you, I am enjoying it too 😄
I feel the same about this 100pcs LM13700 bought on eBay at 1980's price, so they may or may not be real.
In Dutch I alway say "de enige goede raad is voorraad", which translates a bit like "the only good advice is stock". 😉
I personally liked the very small old display, so many uses for that little gadget.
I am loving too,I prepare new diy project using 64x32 oled
I have had some issues with those cheap 555 Timer IC's. Some of them didn't work. I made a 555 IC tester with a couple of LED's, so I can test them out.
I made 555 tester maybe 20 years ago and still using😄
and i love your vernier guage with the battery glued to the side
I love that FM radio you made, it's not so good at reception, but the design and size is AWESOME 👍
The reception is bad bcz I am in my cave 🙂
I usually skip thru videos like this, but I watched this entire video. Great fun. Thanks.
My favorite gadget is the small display, extended with your radio. LOL, that's fun 🙂
Mine too!

It's the best feeling! 😄
SEnsors and anything that interacts with the outside world - thanks man - love it.
I’m glad you found something useful!
Your DIY USB load looks like it will get you in trouble at the airport lol
For sure😄
to be fair< I could have only dreamed of these gadgets being this affordable years ago. personally I think the amplifier boards and the step up/down one are really cool
Yes right now the prices are little bit higher,but still you can find electronics for a $1

Got one of those servo testers and they work very well. I love it.
Glad you liked it!
Love the "discharge"
Its a good gadget
@Hacktuber sorry, I meant your DIY bulb discharger with the wire wrap (heat protection?). It just looks nice.
Informative video. Thank you for sharing. 👏 👏 I like the Arduino.
Glad you enjoyed it!
Does the AtTiny have the boot loader pre burned in?
Yes they have boot loader
what's REALLY Cool are these newfangled rechargeable batteries that output 1.5V with a much flatter discharge curve with USB C port for charging each cell.
I like the voltage mofifier
Love this type of videos
Thx for feedback
My favourite thing is your TH-cam channel Hacktuber. 👍👍 thank you for posting.
Thx sir for support and your feedback mean lot for me.
Regards Marjan
Nice presentation. I like this!
Thank you very much!
Tengo una pregunta, cuánto tiempo le tardo en llegar su pedido del video? A mi me tienen 3 meses esperando un pedido
i like the bluetooth to speaker gadget - i just need the tv audio to bluetooth gadget to complete the set lol
thanks for your conversations
Celui que j'utilise le plus c'est le TP4056 pour mes projets, Bien la mini FM
ALL ARE BRILLIANT KEEP DOING THESE VIDEOS- Johney Guitar👌
Thanks, will do! Stay cool bro👍
I feel like there should be rehab centers for people like us. I already bought almost everything you recommended 🤦🏻♂️🤣
😆 I love cheap electronics boards and modules
Very nice discoveries.
Thanks! I had fun trying them out.
OMG that’s the tiniest radio. So cute.
Thank you,I have a full diy video on my channel
I like your videos and presentings,thanks for it...
Glad you like them! 👍
I like that your digital Vernier has some sort of alternative power. Please show
yes I attach AAA duracel battery,for longer life
@@Hacktuber I did the same with two of mine and another with an Aaaa from a pp3.
Can you run Win 11 PRO on item #9, the SMB?
i love the radio
Me too
I directly gathered the Parts, i like your „modular“ approach…i think i copy this😁
I like your radio! Will you share schematic and sketch?
I have full video tutorial;th-cam.com/video/Ks6lziEVOxM/w-d-xo.htmlsi=ntEWV8HgsOKmmBa6

555 its timer chip,for audio effects need to use different circuits and IC
I love this channel ………..
what is the power draw on that radio you made?
Pull around 20mah if you rock louder goes over 60mah
This was a great video. What is the name of the workstation pad that you're using? I want one for my workstation.
search on Amazon: Heat Insulation Silicone Repair Mat, S-160 Anti-Static Station Magnetic Repair Silicone Work Pad for Cellphone, Laptop, Watch,

Can you make a tutorial on how to make a powerbank in which we can add more of those rechargeable batteries that all powerbanks use?
Nice idea,keep in mind😉
Micro LCD is very nice.
I love it,its the smallest oled screen that I found for arduino projects.thx for feedback sir👍
Can you make a video of how to make the radio??? PLEASE 🙂
I have made that videoth-cam.com/video/Ks6lziEVOxM/w-d-xo.htmlsi=Glgx3ZgCU40PKcGC
nice video, thanks
Glad you liked it!
Nice,thank you:)
How can I use the little display? What are the input pins?
Check my channel and search the project using these words oled 64x32
Wowsers! I haven't seen such a janky servo for about 45 years. And it even has the constant buzz of no proper deadband in the electronics. Nasty!

You can find them all on ebay just with little bit higher price

Have fun playing with them! 😁
Sir, can you help to construct a cheap solar charging system for my e-bike? The battery on my e-bike is 48V 12.5AH 350W. Many thanks

Thank you very much for very kind words and support,I am glad that you love what I am doing.
I love electronics and that makes me happy🙂
I'm sure I could find a use for the servo
Yes many projects can be done
7:30 Can this board be used to charge cordless drill battery? Its 18V system with 5 1860 battery's.
No,that is not possible bcz cant handle with proper current
@@Hacktuber Is there any other board that i can buy to do this task? Battery's are still good and charge but circuit board is dead.
The cheap USB Testers do not compensate for the Voltage they drop or the extra Current they draw running their own circuitry, especially their display, so V will always be a tad low and A high.
buyer beware
That's something to keep in mind, thanks for the heads up!
I want one ATTINY85 development board and one 64x32 OLED screen 😊
Servo tester and lithium ion charger.
Those are good finds, you can use them for many interesting projects.
I dont have the AAA battery step up to 5v but I have all the rest of the items.
Good for you,just have fun with the projects
Good.
Thank you! Cheers!
Me gusta el que regula el voltaje
Useful gadgets YES
6:00 No one still uses these batteries.
8:20 Bless you.
$1 if you are a new user...after first purchase then no more $1 item . Pay full price 😢😮🙄
Yeah, it's a bummer when those deals disappear
Nit sure how correct this us. The attiny digjspark module shown will cist me 3.05 euro
Is that you Alex ?
Alex who?
I no longer use aliexpress as it caused my account number for my bank to be compromised
