Hi everyone!👋

Thank you for checking out this portable Bluetooth + WiFi speaker build I have come up with. As always I will have the laser-cut plans, the wiring diagram and the whole parts and tools list on my Instructables page. Make sure you check my Instructable page too for more details. Let's get started!

For this speaker I decided to try implementing not only Bluetooth 5.0 but also a WiFi module. Here I am using the Up2Stream WiFi module which is super easy to use and delivers great sound quality at a reasonable price. There is also an Aux input which when plugged in automatically disables the Bluetooth or WiFi input letting us make a simpler and cleaner looking speaker with less buttons and switches which is always pleasing to get rid of.

For the amplifier I chose one of my favorite Class D amplifiers - the Yamaha YDA138-E. It delivers plenty of power in to the drivers with plenty of bass and clear highs. One of the best features of this amplifier is that there is absolutely no audible noise being projected when the speaker is not playing. I have tried many Class D amplifier and I can truly say that this one is top of the range in it's price point.

I have to say - I am happy the way this speaker has turned out. My apologies for the crappy sound test on the video but you will have to take my word for it - not only does it look decent but it sounds good too! I did make a few flaws here and there when building the speaker but hey - at least I learned something! Thank you so much for checking this project out, I hope I inspired you to build a speaker of your own. And if you are still hesitating - do it! It is super rewarding and the knowledge you get by making it is priceless. Not to mention the fun!

Thank you once again for tuning in to this project of mine and I will see you on the next one!
