I assume it's a led strip inside, do you think that would be controllable by a microcontroller? Can you see anything from the one you have?

I see maybe what you would like to do.. connecting it with your node and make it light when you receive #zaps? 🤩😁 I remember some did something like that and posted a note, a year ago maybe.
Anyway yeah, I think this is what you looking for. It works with batteries or connected with usb cable. (I opened it so you can see better)

Exactly 😆 There must be some sort of controller to change the color, I guess?
Nope, the color is fixed, you choose it when you make the order. I just found out the exact link, I think it's the same item anyway. I got confused because I bought a second one on AliExpress 😅
