Meet the PartyBar™! Make a wireless speaker, loud enough to fill an entire room! With a budget less than $15, you can have your own Bluetooth speakers made from scratch materials! It's slick, stylish, descent and most of all it's compact and fits in your pocket. This is a great weekend projects for enthusiasts and audiophiles.

It's small but packs quite a punch. With the help of "35mm Neodymium Drivers" the PartyBar™ delivers a solid stereo sound. It's equipped with a 1000mAh Li-ion battery meant to last for 9 straight hours, replacing it with a 2,400 LiPo will result to a staggering 22 hours of continuous playback!

Are those ready made speakers?
A lot of people thought that this was a ready made product, well it's not. It's actually made from recycled materials such as broken speakers, radios & old modules. The project box came from my eyeglass's container :D



Techie Description:
The PartyBar™ is equipped with two outstanding Neodymium Speaker drivers. Neodymium itself is a rare-earth metal. Magnets made from neodymium are light and very powerful, making the speakers more compact and gives a higher clarity rate.

Of course good speakers must be powered by good amplifiers thanks to Nsiway's NS4263 dual 3W SMD chip, the PartyBar™ delivers an excellent audio, good enough to compete in today's market. It has a class AB amplifier with a THD rating of 0.1%. A Class AB amplifier delivers fully symmetrical wave amplification, in short the audio given off by this amplifier is pure and clear.

<p>this is mine !</p>
<p>Hi Puig,</p><p>Do you by chance have a schematic for your wireless speaker?</p><p>Thanks!</p>
Ill will open it and take some pictures aswell drawing the schematic.<br>
<p>Did you get a chance to draw up the schematic and take pictures? Thanks for the help!</p>
<p>Hope it helps</p>
<p>Sure</p>
<p>looking at it i know it doesn't work</p>
Hey dude!! Can u help me with the wirings pls :)
<p>here you have</p>
<p>You getting any buzzing or extra noise?</p>
When i switch it on i hear a low piiiiiiiii, but when the music start it stops, or at least i dont hear it.
<p>i have the same problem, have you found a solution yet? If yes could you tell us so people with the same problem can fix it. Thanks in advance</p>
<p>I've got rid (almost) of the piiiii in a similar project adding an electrolytic capacitor in the input (+ and - terminals) of the bluetooth module. A 470uF electrolytic capacitor removes some noise, but a 1000uF or 2000uF was better in my project. So, I think you could try values between 470uF and 2000uF. I'm not an expert, but suspect that low noise to be radio waves propagated to input wires as when I increased the volume the noise also raised.</p>
hey! Needed help with wirings!! Can u help plss
<p>Hope it helps</p>
<p>will try, thx</p>
<p>Hey, I am not a electronics person; but planning to make one of these. Help.</p><p>Where do we add those capacitor ?</p><p>connecting -ve and +ve power input of bluetooth?</p><p>or</p><p>one in each line of -ve and +ve supply ?</p>
It seems that the current won't go through the capacitor
<p>try to use a different battery for the Bluetooth USB port, that is compatible. If you plug the audio into a smartphone and play music, for example and it doesn't buzz strongly at any frequency then it is the battery. I have also found that using a cut, female USB cable for power only (mine doesn't support audio through usb) and a lithium-ion rechargeable battery with the power to charge a smart phone, gets rid of most all buzz, and a cut male 3.5mm (I think) cable for audio to the amplifier.</p>
<p>What gauge wire did you use? Did you have to use any resistors? I am new to this and would love any help!</p>
<p>its 24 AWG and I did not use any resistor</p>
<p>wanted to make something like this for long..thanks ASCAS!!</p><p>Have used parts from the link, used an acrylic perfume box as case :)</p><p>There is a small problem though..there is a background noise, quite audible when song is playing at low volume/ silence in the song..Please help!!!!</p>
<p>That's an awesome build. Have you tried connecting a 10uF Capacitor to both lines channels? </p>
<p>Hello! I just read the datasheet of TP4056(Battery charging module).It say it Maximum Battery current it can hold is only 1000mA. Is is true? or i have read it wrong?And as you have used 2400mA battery.Can let me know at resistance value to have changed/modifyed in the module?Thanks. Awsome Work!!.Help appreciated.</p>
<p>Charger module for lithium batteries (1S) come at 1Amps rate only. Anything beyond that will need battery protection. So does not matter if you use 1Amps or 2Amps charger; the battery will charge at a maximum of 1Amps/hour rate only.</p><p>Coming to Lithium battery; the maH in battery denotes the capacity. So technically a 2400maH battery which is nothing but 2.4Amps*Hour; will charge in around 2.5 to 3 Hours if you are using a power source 1Amps or higher. If you are using a old mobile charger; which come with 700ma or 800ma rating, then the charging time will increase.</p>
<p>ook.thanks alot</p>
This is what I have <br>DROK<br> &reg; Mini 5V Digital Audio Amplifier Board USB Powered 2-Channel Stereo Amp DIY 3W+3W 470uf<br>And I want to substitute there amp for mine and add another speaker without screwing up here CIRCUT and still be able to access the Bluetooth. Can you instruct me please
I have a question if you would be so kind to answer. I'm building a few of these for some music artists with a cheap auvio single speaker bluetooth square and I want to bypass there mini amp and use a drok 3w/2 amp module with a pot volume control. How can i bypass there amp and add mind without totally retiring there system ?
<p>Nope :( ...have used a 104 (0.1uF) as you had in your pic. Should I try a 10uF instead at each channel's input?</p><p>Thanks for your response, appreciate it :)</p>
You can put a pulldown resistor between the + and - sides of the amp
Why is my mobile battery charging to 6+ volts? I tried it with 2 batteries and they did the same! The funny thing is that once i disconnect the batteried the votlage keeps on rising. Whis is this?
<p>hello,</p><p>It is possible to have a shema? I don't understand the connections with the modules you advice In dx.com</p><p>The capacitors 104 have it mate sense ? where they must trendy ?</p><p>Thank</p>
<p>hello,</p><p>It is possible to have a shema? I don't understand the connections with the modules you advice In dx.com</p><p>The capacitors 104 have it mate sense ? where they must trendy ?</p><p>Thank</p>
<p>Since most of people seem to like this, I'll show it here as well.</p><p>Made it mostly following your instructions for electronics part, thanks!</p>
<p>I've seen that one before, didn't you make a reddit post about it?</p>
<p>I did and it somewhat took off. (:</p>
<p>Hi ASCAS! This is my build :)</p><p>I got the speakers from a broken Monster Clarity speaker, the box from an art shop and everything else from china and from recycling old electronics.</p><p>I'm thinking about building a larger and stronger bluetooth speaker, maybe 2x6W, or 2x10W. any suggestions?</p><p>Thanks!</p>
<p>You show 104 capacitors in the pictures, but do not list them in the wire diagram, I'm assuming they go on the power leeds? </p>
<p>Both 104 go to each channel's input. It acts as a simple low pass filter.</p>
<p>great idea using a glasses container!</p>
<p>what if one wanted to make two bluetooth speakers (one left and one right), how do you sync both to read as one? </p>
<p>I should also state that I'm not an electronics person, but what if one wanted to make two speakers, separating the left from the right? How would you link the two speakers to each other, then to the phone or whatever device is picking up the bluetooth signal? </p>
<p>I have a pair of tv speaker that are 16 ohms and 11 w, and I wanted to turn them into wireless bluetooth speaker just like the one above. What kind of amplifier, bluetooth module and battery would I need.</p><p>speaker- <a href="http://www.ebay.com/itm/378G110A567YAK-TELEVISION-LEFT-AND-RIGHT-16-OHMS-11W-SPEAKERS-SPEAKER-/142179874309?_trksid=p2141725.m3641.l6368" rel="nofollow">http://www.ebay.com/itm/378G110A567YAK-TELEVISION-..</a></p><p>I am a noob in these kind of project so, detailed explanation would be helpful.</p><p>Thanks in advance.</p>
<p>This is fake. You are using a HC-05 module bluetooth module. This module can't stream analog audio, only serial data.</p>
<p>Does anyone know how I can get around this issue I have run into?<br><br>I am using the bluetooth usb dongle that was linked in his part list, but it seems like the battery isn't strong enough to power the bluetooth as the battery runs on 3.7V and the Dongle runs on 5V. </p>
<p>Hiya, I am in the process of making this and I have a question regarding the aux jack, how do I know which leg of the jack is left, right and ground? </p><p><br>~Also, my bluetooth usb dongle has an aux jack on it already, do I solder my Left/Right input wires onto the jack for the bluetooth to work?</p>
Can I add a volume knob in this project?? Reply asap. If yes pls explain it. Thanks.
Hi I was wondering if you could help me. I have the guts of a few bluetooth speakers(808 Tl 808 SL and jawbone big jam box) and i have 2 circut boards from an ilive and polorid and before the speakers died i remeber they worked. So I was wondering if I could use them and wire up a battery to one of them. I was thinking of using the battery from the big jambox as the speakers from it and the 808 tl. If your willing to help I can send pics of what i have and specs of everything.
