Here is an instructable which you can refer to for making PCBs. I'll be making this PCB using the toner transfer method. This circuit will be used to boost the 3.7V input from the Lithium-ion batteries to 5V DC which may be later on used for powering up our USB speakers. I think there is some problem in the output stage.. hi, i have made a bluetooth speaker but the problem is that i get distortions because it is connected to the same powersource. Logitech Bluetooth Audio Adapter (MSRP $28, Amazon.com) My Personal Search for a Bluetooth Receiver. Once that is done, proceed carefully with the rest of the pads. Also, I'll update this Instructable for the mic instructions when I'm done testing it(however the testing won't be done soon, it is on my To-Do though). The main focus will be on designing a low cost audio amplifier circuit around the LM386 and the NE5534. You can easily purchase a Bluetooth receiver from the local shop or use a Bluetooth receiver circuit board to make your receiver. Everything essential is already explained in this post. Here are just a few Bluetooth receiver hacks you can use at your disposal to create a versatile wireless system: 1. The Bluetooth receiver can also have other components depending on your purpose. BluFi supports a maximum of 5 button controls, namely Volume Up, Volume Down, Next Track, Previous Track, Pause/Play. You can also follow me on Facebook, Twitter and Google+ for news about upcoming projects and behind the scenes information. I replaced the 5534 with an LM358 (and changed the wiring to accomodate it) and it worked. We will not repeat it here to save your time. Add Bluetooth to A/V Receiver Amplifier Within 3 Minutes: This is a very simple upgrade that you can do to any amplifier that does not have Bluetooth built in. Therefore, you will end up shorting the Audio GND of XS3868 with its Power GND, which is not a good idea. A line-level signal is a low voltage signal that is resistant to noise. Pair up your phone with the XS3868 module and start playing some music. I'd like to remind again that due to layout modifications, my PCB's pictures might differ from the layout. BluFi is the combination of two circuits, namely, XS3868 circuit and MC34063A DC-DC booster circuit. Are they all bad, or am I just missing something? Share it with us!

Reply I have powered up my Arduino UNO(programmed with blink sketch) with it. You might also need to check if MIC has been enabled using PSKeys. Let's bring it to life by soldering in all the circuit components! cordless telephone) will have a particular address among a range of addresses it has established for a particular type of device. on Introduction. DIY Bluetooth Receiver for Any Amplifiers Under 3$: Today I found some old Bluetooth mono headset its kinda useless for me since you know it looks weird when you are wearing it so I tried repurposing it now lets see what can I do with something with bluetooth and audio capabilities.... Well the firs… Before deciding to buy any Analog Audio To Bluetooth, make sure you research and read carefully the buying guide somewhere else from trusted sources. Well, there have been issues with MIC for a lot of people and I haven't tested it out yet(because I know it'll take a lot of time, which I don't have currently). I made Lm386 circuit and it worked but has too much noise.. You have to be careful because the pads are easily dislodged from the module if they are heated for a long time. This may be done for all the controls. Did you notice any loss? 3x100nF Capacitor, 1x22nF Capacitor:http://amzn.to/1G29rnq, 2x470µF Capacitor, 1x2200µF Capacitor:http://amzn.to/1nW0tlX, 3x100k Resistor, 1x10k Resistor, 1x100 Resistor, 1x47 Resistor:http://amzn.to/1tp60Rh, 1xSilvered copper wire:http://amzn.to/1E8p1fy, 1xNE5534: https://s.click.aliexpress.com/e/_dVZPIjN, 3x100nF Capacitor, 1x22nF Capacitor: https://s.click.aliexpress.com/e/_d8TSem7, 2x470µF Capacitor, 1x2200µF Capacitor: https://s.click.aliexpress.com/e/_d7IrB2Bhttps://s.click.aliexpress.com/e/_dWrNxN9, 1xBC637 NPN Transistor: https://s.click.aliexpress.com/e/_dVb5i6F, 1xBC640 PNP Transistor: https://s.click.aliexpress.com/e/_dUX37mf, 3x100k Resistor, 1x10k Resistor, 1x100 Resistor, 1x47 Resistor: https://s.click.aliexpress.com/e/_dSgNnQR, 1xIC Socket:https://s.click.aliexpress.com/e/_dU34FV5.
