I dont see any significant diff between having a small antena and not. Thanks for the vid.

interesting design; looks less bulky, more elegant, than many shown on RUclips

thank u, usefull ruclips.net/video/n8N7pnrjb2A/видео.html

Bad video

❤❤❤

Beutiful

Beutiful

Use relay shield Rev 2 with selectable relay pin.

Thanks! I rewrite code 5 times ))) but there is no error....

I use only the line in input of the blue board, is it possible to disable this terrible "line in" announcement on powering on of the module?

Hello Dr. Strange

Bruh i test them it's works fine with good bass you have something wrong

Happy

Really cool video for seeing whats inside a fan. Would really be cool to see more videos of diy stuff, tinkering to fixing things :) . Very educational seeing the whole process uncut.

The board power is controlled by a 4409 MOSFET chip. 4409 is a P-channel MOSFET crystal. The positive power supply of this audio power amplifier board is connected to the Source of 4409, the internal IC power supply is connected to the Drain of 4409, one end of the switch is grounded, and the other end is connected to a resistor to the Gate of 4409. Because there is a diode inside the 4409 chip, the positive pole of the diode is connected to the Drain of 4409 (that is, the internal IC power supply), and the negative pole of the diode is connected to the Source of the 4409 (that is, the positive power supply). Therefore, if the power supply is reversed , it becomes that the IC power supply is directly reversed (the switch will be turned on or off), and it will burn out directly. The reason why the Bluetooth module didn't burn out was because it passed through the step-down chip, and the chip should have a reverse polarity protection device, so it wasn't damaged.

There's no diy here? This is professional worker

Seriously beautiful!

Very nice idea💡

Not bad but Making floating shelf would look cleaner

Looks good. I’m looking at some different options for a lightweight bunk for a travel trailer

Хм а смысл в перепайке? В этой плате шина i2C софтверная , поэтому проще i2c шину перекинуть на пины d3 и d4 к примеру !!!

I have this amp PCB layout as well. I only run them with 8 ohm loads. I am aware the board does seem to have shielding issues and very likely the source of the noice.

Hello, great video, is it possible to share your 3d file for printing the case? Greets Tom

have you tried the basic PMA 8610 without volume control ?

Never disconnected the internal antenna. The antenna you should use is 1/4 wave, which is about 3.1cm.

Faulty product.Other PAM8610 amp not have this issue.

no se escucho mucho la prueba de sonido,..

Unplug the aux cord not the power. If it still has noise with aux cable unplugged then it's the amp. It sounds more like your audio device or cable is bad.

Wrong conections, + are - and - are +.

Welcome return .... Long or short your videos are worth watching !

very helpful tips. i just encounter the same situation as yours.

how can I put simple sound on this speaker plz?

I was actually wondering what was supposed to be on the opposite wire end if there was a J-hook on one end. There are three options that make sense: hook-to-hook, hook-to-alligator clip, hook-to banana jack. To me the last option makes more sense if the hook is connected to a multimeter since the first two options of the three assume bridging parts of a circuit and I'm not too sure if that can be very useful.

My bunk bad's bigger in length, and my room is smaller. I have bought this bad from shop I can't return it, please could you tell me how can I make smaller, I never done this kind of work before, I want keep this bad because it was £450 and now no any body buying from me for £300. Please let me know if there is anything salutation? Thanks

perfect

Dear friend, How to change the name of Bluetooth BK800L ? Thanks

I have the same board its connecting but no audio out please reply

How u made that stand 😥

Try building an outdoor antenna with a 50 ohm impedance antenna cable with a 5 km to 30 km long range satellite dish.

What is the diameter of the wire used in this video?

D5 is a spi pin miso or mosi used for the micro sd card reader better to use d3

Fast and easy solution, thanks for sharing!!

I hear a lot of unpleasant hiss. Hopefully you have upgraded to a better camera and microphone since this clip was made. This way all of us can hear what it sounds like and not have to worry about whether we are hearing the camera noise or the amplifier noise.

Thank you so much i was look for help for 1-2 months now.

Thank you for this! I was dreading having to code a bar graph myself for a little project I'm making, so finding this is a really nice surprise.

Can use this feed back of a encoder
