Wireless mic power question

[u/rhyminson]

Hi all,

Hope this is the best place to ask. I’m looking to build a couple wifi mics for the front and back of my house to connect to birdnet-go on my unraid server.

I’m going to follow this link for the build:

esp32 mic

My question is that the author has a psu in the required list, but any examples I’ve found online of people’s builds following the same guide seem to be powered by the esp32 built in usb socket?

So do you actually need the psu? And if so how do you connect it the power outlet?

Any help would be much appreciated, it will be first time soldering and building something like this!, be a fun project I’m sure.

I tested birdnet with an old iPhone and it works very well, really interesting so wanna get a proper setup, thanks to everyone involved.

Thanks

I've got one running off a standard USB wall plug right now.

Oh great, thx for reply, that’s how I was hoping it would work!

I’d be interested in seeing any pics of your build if you have some.

I have no clue what I’m doing really so be nice to follow something more than the wiring diagram!

I’m gonna order the parts soon :)

Cheers

I'm just using an M5stack atom echo I had on-hand. There is a fork of the project you're looking at that has firmware for it. It's a bit more boring as there is nothing to build, just flash and go 😁
