7 NEW AliExpress FindsAdded:
Of course I got it.
Oh, nicely packet.
All right.
Okay. How to open this thing?
I need the scissors.
Okay.
Feeling nice.
And we have a type-C charging cable.
Oh, here it is on the side. We have the type-C connector for charging.
And right now indicates with four LEDs that is fully charged. And when I press the button, whoa, did you see it?
And we have an animation on the LEDs.
Safety lock off. Pressing not working.
one more time so you can see it.
Let me show you.
Nice.
In description, it doesn't says about the capacity of the battery. But let's check with how many Why is flip?
Okay.
How much current is pulling? 200 milliampers. That is a nice current for charging the the battery.
Okay. Indicates the fourth LED that is almost fully charged. And can you operate while charging?
No, you can operate while charging.
Moving. Yes.
And beside that, you can start the gas.
Take a look. Okay, it says that you can light a candle.
Let's try that now.
Yes, you can start a candle. Nice.
Turn it off.
It's smooth and I like it because it's long so you can light up candles or start the gas stove. Nice.
Beautiful.
No bubbles.
And forgot to tell you that this thing cost around $2.7 for two of these LED lights. and also the USB charger.
And let me tell you, okay, these are lights for night fishing.
And right here goes the line so you can see in darkness. And also we have the charger.
But why it's not working? Because you need to open it.
And the battery it's in opposite way.
And you need to place it right just like this. And take a look.
One.
Open it the other way.
And now I have two lights.
But did you see the battery? Take a look how small rechargeable battery. And this is the model CR425 3.6 volts 25 milliampers 0.09 W hours. Take a look how small it is.
And if you want to charge it, it goes like this.
Press it for the one and for the second one.
Nice.
I need this kind of battery. Take a look how small it is. Let me show you.
Okay, let's measure it.
Long 22 mm and diameter 4.1 m.
That is awesome. And tiny one.
All right.
And if one battery is 25 milliampers with how much it will charge? Let's see.
Also, we have LEDs on the charger, blue and red. 0.007 milliampers. That is 7 milliampers.
Meaning in 3 hours we will be fully charged. When I place both of them, it goes to 14 or 13 milliampers. That is perfect.
Oh, I like it.
Can you see it? How small it is? 25 milliampers. Wow.
And the light is very bright.
Isn't that nice?
Okay, all the links for the products that you see in this video will be in description below so you can check it.
I can see bubbles. Finally.
Finally bubbles. Ah!
Ooh, nice.
Ooh, more bubbles.
What we have here? Assembly instructions. They include a tiny screwdriver, instruction manual, the plexiglass front and back panel with bunch of screws and screwdriver as I said. And here it is the main module.
Ooh, looking nice. A bunch of electronic stuff.
All right. All right.
We have three inputs, type A, type-C, and micro USB. Also, we have one push button right here. It says that is for on or off.
And al also we have the dial knob with pushing or pressing left and right.
The output voltage can be uh selected on the type a USB connector or through this fast connecting connector right here. The plus and the minus. Also we have three LEDs for indicating some stuff. we're going to figure out and the LCD screen itself.
But first, we going to assemble.
Oh, nice.
And the second one.
In three, two, one.
what it says input. Oh, because my charger is quick charge that can give 12 volts maximum. I'm using different charger right now and it trigger to the input to be from 5 to 12 volts. You can monitor that on this LCD screen that the input voltage is 12. Right now we are not pulling any ampers. And with this button, you can control the output to be on or off. And you can see that the green LED is turn it on, meaning that it's on. And the blue in meaning that is auto trigger the the charger.
And with this knob right here, which which goes left, right, and you can press it, I can monitor.
Can you see the screen? Well, okay. So when I go to the left, I can monitor also the the temperature one. Another left that that the output voltage is set on 9 volts. And I can turn it off. Take a look. Another left. We are back in monitoring the input voltage. And when you press on the right, you can select to see the watts, the amper hours, the time, and back to ampers.
Beautiful. One more time to mention this module. It's a DC toDC converter.
The input voltage can be from 4 to 13 volts input and the output can be adjusted from 1 to 30 volt. Turn it on and we have 9 volts. I'm going to turn on the electronic load and take a look.
It's pulling one amper and I can monitor the watts. that it's around 9.8 watt 3 amp 0.004 004 amp hours.
Also, the input voltage can be monitored. The and the temperature now rise because the the MOSFETs on this PCB boards are working. Okay. With holding the button and the volt icon will flash. That mean that you can change it. Oh, other way.
Remember right now we have uh 12 volts output or input but I'm going to set it to how much let's go with 14 volts for let's say and this and what it says over power protection because it pulls more than 15 watts the module protect itself.
Nice.
Okay.
Oh, what we have here? What it says?
Mobile magnetic card holder. Nice. Oh, bubbles.
Oh, first remove the cables. You want to see what kind of cables are included in the package.
Nice.
Oh, I have already touch it.
All right. Nothing here.
And the bubbles.
And it's already on. It shows 40% capacity and my unit is 10,000 milliampers.
Ooh, and feeling nice. The plastic is very nice. It's smooth. It's not like a cheap plastic.
So, let me explain. On the top, we have the type-C double function. Through this connector type-C you can charge it the power bank and also you can charge the device or smartphone. We have a holder for the power bank. So you can place it like this and put your phone which is nice.
Oh, such a nice feeling.
The most important thing and cool thing is the fan. Take a look. This power bank have a a cooling fan.
And I like very much this transparent part where you can see the electronics.
You can see the capacitors, the connector, type-C connectors, the fan.
And let's take a look. Will it work?
What?
Can you hear it?
The cooling fan is working. Really?
And right now my phone is charging.
What does it says? I'm going to remove it and let's go again. Yes. And it says fast wireless charging.
But take a look now at the cooling fan with those RGB fading RGB LEDs. It's awesome.
And ooh and I can feel it the airflow. I can feel it. It goes in this way.
But how it works? How will it will cool down the the smartphone? If you and I'm going to plug in and yes, right away it pulls what? 5 volts 500 milliampers.
Hm. And we have a flashing second number of the indicator.
Oh, it resets. And now it PD trigger sets to 12 volts and it's pulling 1.5 ampers, 18 watts.
Nice. Take the power bank together with the cable, which is pretty nice. Remove the cable, plug into the connector to the phone and is charging also through the cable.
But how much current is giving? That is the most important thing through my USB tester. We're going to find out.
And what does it says?
Whoa. It trigger 9 volts, 1 amper, 10 watts. Right now the phone is charging with 10 watts.
I like it. This is a old iPhone, but it will work very fine. It holds the phone and in the same time you can charge it and watch on your phone.
Pressing. Why it's not charging?
Oh yes, it will. Yes, it starts to charging.
charging. Leave it like this.
But you can ask more for from this.
I can't believe it. They sold 17,000 of these CYD modules.
And what does it mean CYD? Cheap yellow display with ESP32 chip built in. And this module is very useful and many people have bought and is very popular. Let's power up.
And you can see that I already upload the software Bruce Predatory software which can be found on the Bruce website.
You can find it on the internet. Just type Bruce predatory software and from here from uh web using a web flasher you can uh program your your module. You can do it on M5 stack lily go cy cyd 32 or any custom board.
Here we have two connectors where you can attach these small connectors. So you can uh make the connection between the infrared receiver and the the module. It go right here.
Whoa.
Okay. And when I press the button, take a look. It reads the code also. You can remember that code and later use it if you want it. Isn't that a nice hacking way? Uh, choose let's say a jammer and take a look. Right now is sending a bunch of infrared signals. So, can be a jammer. Attach the module. Uh, 433 MHz.
This one is the receiver. This one is the transmitter. We're going to choose RF.
And we have also couple of functions here. You can choose a spectrum.
I have a 433 MHz remote. Take a look.
And it's getting the the waves.
Okay. But take a look what will happen when I press the button on this remote control.
And take a look here. It is the recorded code right here.
Take let's try it again. Yes, it shows in binary and the key also.
Oh, this is super nice and hacking device.
Or just choose Wi-Fi attacks, target attacks. It will scan all the networks around this module and take a look. If I press it, I will send some packages and the router will be not working.
I got it. And by the way, there are some damages on the package, but never mind.
OH, finally some bubbles.
Oh, I have a instruction manual. This I need to read it.
OKAY, this is so exciting.
And it's a DIY.
More bubbles. What?
These are empty.
Oh.
Okay. What are these?
Oh, pads. So, we can place them right here. Okay. Okay.
Okay. We have pads. We have the iron, the handle.
Time for 360, of course.
And let's see what it says in description.
Power consumption 72 watts default tip.
That is my version. T12K display 0.96 in OLED. Handle cord material silicon handle cord length about 1.1 m.
Temperature range from 200 to 480°.
Control method knob adjustment. And uh size is 88 mm by 41 by 38 mm.
Okay.
The brand is Quico.
Auto sleep auto power off. Vibration wake up. Hm. We're going to check that rapid hitting mini DC version of soldering station. Highlight this. It's simple. Whoa.
Okay.
Now, we're going to add this one.
Okay.
Power unit. I'm going to turn on in three, two, one.
Oh, and right away it start to hitting.
Take a look a smoke from the first time turning on the heating element and take a look. You can make a calibration current 350 ready ratio 100%.
You can adjust the auto sleep.
It's now set on 10 minutes.
Auto power off. You can change it to 30 minutes to 1 hour, 2 hours, whatever you want. Boost duration, boost degree, wake up method. Take a look. Button and handle.
Button only. Button handle.
Button handle. All right. Buzzer switch.
You can turn off and on that sound that you you are hearing.
Battery guard, battery protect at 12 volt because this thing can be powered by a battery.
There is that kind of settings. Convert units. You can change from Fahrenheit to Celsius, which is super nice. firmware and factory reset. And if you want to go back, hold it for around 3 seconds and we are on the main screen.
Stable the temperature. And now it's set on 240.
Let's measure that and take a look. It's here 24.
I'm going to increase the temperature now to 300 and take a look how fast is going to 300 in one two seconds maybe. Okay, let's measure again first to add little bit thin on the tip.
Whoa. And take a look. 295 29 99 99 300.
Wow, I love it.
And what will happen if I remove the soldering handle?
Oh, alarm. Alarm. No tip handle.
Okay. Okay. Looking back.
Nice. And the other thing when you power off and turning on it will remember the previous set temperature which was 250°.
Okay. Beautiful.
And the handle is also beautiful. Take a look. Quico T12 9007. The handle is all right. And you can change the tip to whatever tip you want. Beautiful.
Beautiful.
And the last package for today video is the very popular mini board which is ESP32 C3 with built-in OLED display that is 64x 32 pixels or 0.42 in OLED module with caramic antenna. ESP32 super mini development board with Bluetooth it says and also a Wi-Fi. This thing you can get from AliExpress for starting from $4 US and it's going up every day. The prices are going up.
Crazy. Okay.
They send it without bubbles. This thing which is super fragile at least came in this plastic transparent case which is nice together with the pin headers that need to be soldered on the board. And take a look at that small screen and what says Mr. Google about this board. And for those who don't know what kind of board is, this one is a ESP32 C3 with built-in uh 0.42 in OLED display. A compact cost effective internet of things development board that costs from 0 to $5 featuring 32bits processor, 4 megabytes flash, Wi-Fi and Bluetooth, and is ideal for wearables and small projects.
Okay. So, here it is. The small OLED screen. We have one reset button right here. The boot button. This is the caramic antenna. The type-C connector for programming the chip which is on the other side of the printed circuit board.
Here it is. And from the side we have the digital or GPIO pins with me which means general purpose input output pins. And when you solder these pin headers you can hook up all kind of sensors or buttons or LEDs.
And I needed one more of these. That's why I order it. But here it is my old one.
And let me power on. And I have already installed it on this a tiny flappy bird game. And yes, without adding external button. I'm going to use the boot button. And take a look. The smallest game in the world.
Come on. Jump, buddy. Jump or fly.
one point.
I can barely see where I'm going because the the OLED screen it's super small.
Okay.
Oh, that's Oh, you get the point.
