Thank you for your teardown video. I've ordered two of these in the non-battery variant for use in a project device, and want to control power via an external relay. Your video has given me some great information on how to achieve that. Thank you!

[@jj74qformerlyjailbreak3]

I had sent seen this video but I found a couple of these and made my own block diagram that matched yours. That’s really reassuring to me. Thanks.

[@PallavAggarwal]

Great👍

Thanks for the teardown.

Welcome! Hope you found it useful.

Great video with every details. I'm excited to get these to showcase my music components setup. But i want it to be active while plugging in through charger only. Does removing the battery from inside will work for me? If yes i will definitely get these. Your responce will be immencely helpful. Also will it power on right away when it gets power through usb or needs to be powered on everytime by pressing the button?

[@maicod]

Hi Pallav, Thanks for your very clear video. Do you know if the Mic is analog or digital ? if analog could I connect a line level signal by removing the Mic and soldering onto the pads of the Mic ?

[@PallavAggarwal]

It's an Analog mic

[@maicod]

@@PallavAggarwal Thanks it now responds to music from my pc (through a wire). The Mic is gone :)

Thank you very much for your support ❣️!

[@flsabvb7578]

Question please. If I wanted to use 2 of these in my car couldn’t I wire both together and to a power source in my car and it should be fine correct. I’m asking because I don’t want to mess anything up. Thank you

[@ivanlam5131]

What kind of rgb led are they. Ws2812? I want to increase the amount of leds.

[@vantruog500]

Yes

[@neofitosmihail4272]

does it work when you charging ???

[@PallavAggarwal]

Yes, it works when on charging.

hello . sir i have 1 one question . what is first layer 2:56 material ??? is that acrylic ? ok what is black layer and what is white layer ? ty for answer me

[@PallavAggarwal]

Its a plastic.

I got no qr code with the instructions..how do I download the app to use it on blue tooth,or is there another way apart from Bluetooth which won't recognize it when it's scanning

[@kathleenpeters3407]

Mine was the same no code,I'm never reading comments again,I see these comments praising it,and how good it is,buy there's no way to ask a question about the product,but I got my money back from the site..I've a small 1 I gave 4 euro for,a few weeks ago,and it'd really good and the sound is great for the price,and so straight forward,turned it on,done the blue tooth with the phone,and it connected straight away...

[@iceho6460]

Is there a connection point where I can solder input wire to connect directly to audio source without having to use the mic pickup? This is for audio accuracy reasons.

[@PallavAggarwal]

I think you can remove the mic and give millivolt audio input. Need to experiment to see how it goes.

[@iceho6460]

@@PallavAggarwal Thanks for your reply. I've tried that. I managed to de-solder the mic then solder two pieces of wire as the audio input wire but it fail to work, in doing that it ruined the LED bar when I solder back the mic LOL

[@PallavAggarwal]

@@iceho6460 hmm.. Sad to know it did not work but great that you attempted. If I get time I will check as logically it should have worked.

[@timsolle67]

Can the sound sensitivity be reset

[@PallavAggarwal]

I don't think that can be changed unless you access the mcu via your custom code

[@timsolle67]

And where would I get a custom code

[@PallavAggarwal]

@@timsolle67 you need to 1st understand the hardware and then write your own code.

[@timsolle67]

@@PallavAggarwal yeah I figured that I just need to know where to get codes

[@saliue]

@@PallavAggarwal A bit late but 1:59 "Learn and record the environmental noise spectrum" I have been wondering what that means because pressing 2 buttons simultaneously doesn't do anything

[@ke110]

I am unable to connect Bluetooth is there a way to activate bt on the rgb bar

[@PallavAggarwal]

I don't remember now but a button should be there to activate Bluetooth. Please check once.

[@ke110]

@@PallavAggarwal i have searched many reviews, but have not been able to find the solution

[@-Constantine-]

I know that this video is old but i would realy appreciate if someone could help me. Is there a way to adjust microphone sensibility or the ambient sound cancelation? i have the same version as the video (without phusical button for it) it says "Press two keys at the same time" for learn and record ambient noise. The screen turns blue for a momment but it doesnt seem to have any difference after. Also the microphone sensibility option in the app doesnt seem to do anything also. Thank you in advance!

[@oilyexploration2085]

Hi I want to upgrade the battery in mine what would you suggest bigger the better 😀 is that a lipo 250 mah in there?

[@PallavAggarwal]

As the charger IC used says suitable for single-cell Lithium-Ion - would go with a lithium-ion battery but I feel both type of batteries should work. Charger IC detail: www.analog.com/media/en/technical-documentation/data-sheets/405442xf.pdf

[@aminshoghian2271]

Is it possible to reduce mic sensivity without phone?

[@PallavAggarwal]

Never tried that, if you have access to MCU firmware, it should be possible. adding resistor in series with MIC, might help, you can try.

[@en0n]

Hi, it is possible to disconnect and bypass the battery and use USB to power the LED light bar directly?

[@PallavAggarwal]

Hello David, I think it should be possible although I have not tried. If with current design it doesn't work we can modify a little where we remove battery and connect USB output to input of 3.3V regulator, that way it will work..

[@mrdean004]

Great content. My question is how did they control the led colors ?

[@PallavAggarwal]

RG LED light bar is using digitally control RGB LEDs so MCU sends RGB data over the serial interface to change the color of the individual LED.

[@mrdean004]

@@PallavAggarwal ohk. Thanks Sir

[@PallavAggarwal]

@@mrdean004 you are welcome!

[@sarangwarad3174]

Hi Pallav Sir, how long does the battery last on this product?

[@PallavAggarwal]

I have not checked the back up time. Back up time will also depend on how much you are using the RGB Bar light. More the LEDs dances to the ambient audio, more power it will consume.

[@ishankantisamantaray6184]

Cn it be modified to take 3.5 mm audio input?

[@PallavAggarwal]

Yes, remove Mic and add audio input.

Need to open and check if the battery is still connected? In good condition?

After using it for one day now it's not turning on and not showing the the charging sign

Mine is different but the guts shouldn't be too different.

I didn't realise it wasn't a speaker...it's only lights that work...waste of money..I nearly ate the bar,I was so sick of trying to bluetooth it....
