This week I build a DIY bluetooth 4.0 audio receiver. I used the CSR8635 bluetooth module, a recycled lithium battery cell that I got out of an old laptop, a TP4056 battery charging & protection IC and a DIY PCB I made myself.
Here are links to these items if you plan to build one yourself:
In this episode we are going to build a bluetooth speaker amplifier based on the TDA7492P class D audio amplifier coupled with a Bluetooth 4 module. We are not actually going to build the amplifier module because we can get that from China, very affordable, it only costs around $12 shipped which is way less that it would cost us to buy the bluetooth module and the TDA7492P individually not to mention the cost of fabricating a PCB of this size.
So we are actually going to use this module and build the final product with a nice enclosure and a suitable external power supply
Here are some links for the parts used to build this project:
Hi and welcome to a new InTheMail, this time we have allot of items to look at and some of them were ordered 2 or even 3 months ago but due to the postal service madness that happens every year during holidays they arrived a bit late.
The video is split across two parts to avoid making it too long so make sure you watch both parts.
Usually when I order stuff from China mainland to Romania it takes about 3-4 weeks to arrive while stuff from Hong Kong takes about 5 weeks to arrive. However every year orders placed starting from about 15th of November up to 31st of December take very long to arrive sometimes even arriving after 8-9 weeks. So right now about a third of my orders are late or missing because there is also a good chance they will never arrive once they go past the 8 weeks mark.
A list with links for all the items shown is in the video description so do check them out.
