cool design!

Thought you would’ve been sponsored by pcbway

We really getting sponsors in youtube shorts now?

Would love to see the improvements

Hi, I have been wanting to make an amplifier for my mic that also allows reverb. Can you do something detailed like this? It does not have to be super loud. I just want to sing on the street and try to make some money. Thank you. :)

Thanks

The buttons literally send a pulse of the music down a wire, wach button has a different resistance causing a different pulse and the computer figures it out in its hardware

💯

I have one of those lg earphone, they lasted me around 7 years and really good

I think that this is how wired remote controls from the 70s worked, I found one and opened it up and I was disappointed that it was just a lot of resistors, maybe a diode or two. But potted ICs are the worst, just so boring and you can't learn anything from looking at it.

Beautiful

Thank you, that's a game changer 👏

Thanks for the simple and also very beginning friendly vid

Mines like 200,000 Mah

Mine is Bigger ❤💯

Some do have microphones like geekbar vape it even says mic but its on the pcb not the thing in the video thats different

I want to understand this but don’t know electrical jargon

Thanks for the Knowledge brush up

❤️

What a great channel

Noob question, but is it as damaging or dangerous when I use it with my powerbank instead?

you have a lot of space for a 2mm chip... it's nonsense! you can use bigger voltage regulator! tiny chips are for tiny projects and... tiny currents 😊

why not add some screws beside the chip and then screw on a heatsink? or maybe you can make it so that the chip controls the output voltage using a mosfet, which should also be able to solve the problem

I playwd with electronics a bit when i was a kid, and now my children are old enough to start. Ive been thinking forabout little kits like this to build together... Anxieuouly awaiting version 2

How long does it take to get fully charged?

This is cool! I love vintage stuff, I collect myself

Unfortunatly there is no way of turning of the voice. Its included by default in the sdk and usually manufacturers dont change much and just compile in the default template because it saves money and they wont need to hire programming people. Also the sdk is not really fully documented well. Some boards that dont have usb sound card functionality can still have it implemented in the firmware and board layout (becauss again manufacturers are lazy to desugn their own thing and use premade schematics) but they just dont place a resistor or jumper disconnecting the usb data lines but leaving pads that can be bridged. I had some models like that. Also if you do plan on tinkering with the firmware, they can be programmed using usb in DFU mode. You have to put a specific signal across the usb pins to put it into dfu mode. The Dfu mode is burned into the bootrom of the ic so you wont erase the functionality. The chips also use UBOOT as their bootloader. They use JieLi's sdk to compile and flash the code onto the flash

My 2x 200 Watt HiFi with boxes and multimedia server was still cheaper. How? 'My sponsor gave it to me. But lets be fair: that chip may be listed for 2cts, but 2 cts is not gonna get you that.

Disappointed. Why go through all the trouble, and it still requires a barrel jack. Make it use usb C PD atleast 😉

does the ip2721 support 100W?

999.0 volts🤔🤔🤔🤔🤔🤔🤔🤔🤔🤔

I bought a 40,000 mah battery on ebay. It would charge my phone to at least 80%.

😂😂😂😂 biggest... joke.

The same thing existed in the UK, a service from the Rediffusion company. Their service lines were on the same poles as the telephone cables. They had four stations selected by a rotary switch, usually BBC Radio 1,2, 3 and 4. I seem to recall one of the channels switched to Radio Luxemburg at night. My grandmother had one until the early 1970s, when the service closed down because radios were now so cheap. The speaker units often had beautiful wooden cabinets and you would find them thrown out with the trash. I collected a lot of speakers and audio transformers from these, when I was a kid and just getting interested in electronics.

i dont have a solder machine

Be sure that your powerbank has the capacity noted on it, otherwise it might get confiscated, regardless of size.

Well, if you're a technician or hobbyist you'll eventually use them. I'd use other methods to test the capacitors other than the AliExpress device

I live in America and have seen a couple of these over the years at thrift stores. I could never figure out what they were until I seen this.

In that history book, there is a pocket radio in a black case. I have one!

Thank you

I just want to say thank you for having the title in English and actually speaking English. I gave you a like for that reason. It doesn't cover the amplifier board i have however. All the other videos I have found on the board I have, have the title in English but they speak some foreign language and I HATE it when people do that. I consider them "clickbait".

You had the Bluetooth transmitter in the floor ! You should have tested the range when the transmitter was atlas 1.5 meters off the floor

This is a communist thing?

🗿🗿🗿

So basically, they invented amplified speakers as reduced cost versions of radios. That seems pretty forward-looking, now.

The OnePlus is only drawing 18w from the power bank because it uses a proprietary protocol to communicate with it's original brick charger and then charges at 80w.. you can confirm this by taking a look in the USB A port of the charger (if that's what it is using) there will a extra pin in the connector other than the USB connetors..if it's using type c it's not possible to see the extra connetor but it's there..all of the phones which say fast charging like 100w 80w of Xiaomi OnePlus etc use their proprietary protocol and that's why don't charge at that speeds other than with their original charging brick
