Look at My Shiny Crystal Balls!

I've got some gorgeous balls - you really have to have a look at them...

I got several of these crystal balls for Christmas from AliExpress.

They are pretty nice, but the default display is pretty basic. The PCB is on the minimal side of things with just three resistors and six LEDs.

So I decided to do an upgrade. I’ve added a ESP32-S3-MINI, a microphone, and support for battery power!

It’s pretty cool - I can now use the amazing WLED software to control my balls!

I’ve put the KiCAD project up here. It still amazed me how simple a PCB for an ESP32-S3 module is.

As always, the video is full of more details - so have a watch and let me know what you think!
