Hi Sorin. The line of pam amps are pretty impressive, I've built a few projects with the different chipsets, and all have worked out well. I've been watching a bunch of home made Bluetooth speaker builds lately, and I must say, the few speaker builds I've seen of yours have been the better ones. You have a good understanding, of how best to utilize speaker drivers that other people wouldn't care to use. You also seem to understand, that no every portable speaker has to fit in your pocket, having to use tiny drivers, but crammed to capacity with batteries and other components. I like the way you keep these home builds simple, and effective. (Not to mention) using salvaged parts to repurpose them. Thanks for making interesting informative videos. Oh yeah,,, rules of cats,,,,, they MUST investigate speaker boxes.
Imi place ca abia mi-am dat seama ca ai vorbit romana la inceput :)) fain (de acum, o sa comentez in engleza aproape tot timpul sa inteleaga si cei care nu sunt din Romania)
Great project as always! Full of info and mistakes to avoid when building homemade Speaker!! I liked the Audio knowledge shared and also about the battery/ 18650 pack. By far the best Audio Build around on TH-cam, everything is not about the esthetic, but more about the knowledge shared through the whole video!! Keep the great your work!! PS: I would have spray painted the case in black, but it seems that you are fine with the laminate wood color :P
Proiectul este foarte bine explicat, componentele sunt best buy la pretul asta, cat despre video... Dureaza 13:37 minute :)). Meriti mult mai multi subscriberi decat ai! Succes! ;)
Scosche car door speakers are much cheaper too I also would highly recommend sony car door speakers or scosche car door speakers from Walmart if your gonna use speakers for that project
Nice work, for easier battery management use a DC/DC buck boost module ~$1 and a USB 18650 charger protection board ~$1 with multiple 18650 cells in parallel, use the DC/DC buck boost module to bring the voltage up to a constant 9 or 12v or get a lower voltage amplifier and better yet one with built in bluetooth.
hi. thanks for the feedback. that will work too. but you will loose some power, because the step up converter efficiency is not 100%. usually this method is used for low voltage amplifiers 5 - 6V. you can get 12-15V from one or more 18650 cells connected in parallel, but when the battery voltage drops lower than 3V, it will be difficult for the step up converter to get it up to 12V and 1A. the efficiency will decrease to 70% or even less. you will loose a lot of battery power. the charger will also need to be very powerful. for example to get 12V 1A from 5V at an efficiency ~80% you will have 12V*1A=12W; 12W/5V=2.4A; 2.4A/0.8 (80%eff)=3A. you need a 5V and 3A charger. step up converters are useful only for low power amplifiers. I've made a 2x6W bluetooth amplifier with this configuration and it works great. but for powerful amplifiers you need a 2A or more, constant power source.
How about including a solar Pannel and charging circuit, Bluetooth and wifi would make it a wee beasty, fab simple easy to follow vid, love the calculations and examples. Cheers
Nice build but i m having doubt for the battery run time as you said run time is of 10hrs for 2000mah which means it will consume about 200ma at 12 volt and it means power output should be of 2.4 watts and you are saying it as it is providing 30 watts
hi. the current consumption of an audio amplifier fluctuate. it depends on what kind of music you are playing, songs with powerful bass sounds drain the battery faster, so it may last less than 10h. also the current consumption is much lower, it's not 30W continuously. the average current consumption is much lower and the peak power is 30W, for seconds or fraction of seconds, for example when there are bass sounds during a song. if you play only bass test songs, the battery will probably last only 2h. and the last thing, the power of audio amplifiers is exaggerated by the manufacturers, to sell their products more easily. in reality it most likely has less than 30W. so this audio amplifier has a maximum (not continuously) output power of almost (exaggerated) 30W, depending on the song frequency and volume level.
Good morning. Awesome explanation and thanks for the vdo. If I want to buy this speaker from the speaker shop what is the Watts, Ohms and diameter of the speaker I have ro ask ?
hi. I didn't save the links, so it took me a while to find them. th-cam.com/video/-7fuHEEmEjs/w-d-xo.html th-cam.com/video/V42iRj0Toq0/w-d-xo.html th-cam.com/video/yJg-Y5byMMw/w-d-xo.html th-cam.com/video/C6IaUMAg3Dc/w-d-xo.html
very nice video. Can I use 4700uF 25V capacitor and if I want to use 2 PAM8610 kit with 4 Speakers the do I have to use 2 BMS module to give them individual supply Also the 4.7Kohm resistor of how much watt You are using a Speaker of 100W. the amplifier support 15W
hi. yes you can use a 4700uF 25V capacitor. you don't need 2 BMS boards for 2 amplifier modules. the BMS board is to protect the battery pack, you can connect 2 amplifier modules to a BMS. the speaker drivers should have a higher rms power than the maximum power of the amplifier.
the supply power is ok. you probably use 4ohm speakers. if you use 2 or more speakers in parallel, they will make a lower impedance and this could damage the amplifier. you need to use 2x 8ohm speakers for this amplifier. or if you use 2x 4ohm speakers, you need to add a heatsink on the PAM8160 IC.
Hello sir, thank you for this wonderful project! During 6:44, what are the directions of the red and green wires on the jack? Right or left? Maybe you explained it in the video but I cannot hear the video, that is why I am making a DIY speaker :) Thanks!
hi. the colors don't matter. the tip of the jack is the left channel, the middle (ring) is the right channel and the base (sleeve) is the ground. you can connect all the components and then use an app on your phone, or the sound settings on a PC sound board, to check if you connected correctly the left and right channel. if the channels are not connected correctly left and right, just reverse the wires for audio left and right where it's easier, on the audio jack, potentiometer or the amplifier audio input.
@@Sorin_DIY Thank you so much! Because I was using a female socket before the jack, I asked you which color is left or right channel. Finally, I found the wiring diagram of the pot on the internet and connected right cables :)
is there any noise on sound and is there any background noise without playing anything or is there any amplifier with Bluetooth chip integer that you recommended with to the people who has more budget
hi. there is a small background noise, when the audio jack is not connected to anything, or when the jack is connected to the phone and there is no music playing. but this is common to almost all amplifier boards. I've installed the volume potentiometer to my speaker, so you can just turn it down, when you don't use the speaker, or when you unplug the cable, so you don't hear the noise. the amplifiers with audio bluetooth receiver included have an auto-mute function, when the bluetooth doesn't receive any music. that's why they don't have background noise. but is the same as turning the volume potentiometer down. I will test more bluetooth amplifiers in the future, to see which ones are better.
Hi Sorin, thx ur projects are always so great, still waiting for the Variable voltage Power Supply. I plan to use the same protection board as you, the 3S Battery protection board, but how to know when to remove the power cable from the created project?? I mean for the TP4056, there are 2 leds, one for charging and another when the bat is full, so it can be disconnected. what about 3S proctection board??
hi. some protection boards have LEDs to show when the cells are getting charged. this one does not, so we don't know.. it takes 3-4 hours to charge the 2000mAh battery pack. you can use a voltmeter/ammeter, like I did in my cordless drill conversion video. when the charging current drops to "0", the cells are fully charged.
@@Sorin_DIY thx, and effectively I am getting exactly the same 3S board, so without any Led to indicated when the charging prossess is done. I ll look to the cordless drill project for more info. is there any risk if I leave the pack charging, since the protection 3S board is there to cut the charging??
hi. you can leave the charger connected, even if the cells are charged. the protection board will stop the charging and the speaker will work on charger power.
hi Joe. MDF is actually better than what I used. it creates a better resonance, because unlike laminate wood sheets, it doesn't have flat plastic surfaces, which creates echo inside the speaker box. MDF can absorb sound a little better. for this speaker size you can use 8 - 12 mm MDF.
Great work, thanks for sharing, What is the size of that small heatzink for the chip or Where can i find that?! Do i need special adhesive for that or a simple super glue will work?!
Hi there. I tried both pam 8403 and 8610. 8610 worked best.i already had 18650 type battery. I used 3 of them as mentioned in the video... It worked... But i didn't used the bms board and capacitor. The capacitor available here is 25v instead of 16v. Can i use that? What is the true purpose of the capacitor in the circuit? I have 3s charger. Do i need bms board? Please help
hi. you need a 3S BMS protection board, otherwise you will damage the lithium cells. you can use the 25V capacitor. it will help to keep the voltage stable, when the current consumption fluctuates.
@@Sorin_DIY i have decided to use a powerbank. I can provide regulated 10v, recharge the batteries, battery protection... .e.t. c. So do i still need the capacitors?
@@Sorin_DIY if i connect 3 batteries in series i can get 10-12v. How much current will be there?. After some use the battery voltage will be down to 7v. So the amp will not work.is there any other method for regulating the 3 batteries to 10-12v till it drained?
yes. you can make a 3S battery pack (8 - 12.6V) with a 3S BMS protection board. then a step up converter, which will increase the battery voltage to a stable 13 or 14V. and a 12.6V charger for the battery pack.
@@Sorin_DIY hello. Thank you so much for the reply.today i bought Xl6009.used 5v 1amp to step up 11.5 volt. But when the speaker reaches 70% volume it wont play. Instead it provide noise. Any solution to this?
This is by far the most in depth but easy to follow tutorial on this project
But I don't have thermal paste how to apply heatsink without thermal paste
Really nice build. You did a lot of things *right* to get the most out of this. Separate ported chambers with opposing ports was genius.
When that bass dropped, I got back the bass my headphones lacked! Thanks Sorin.
