Powering ATTiny project with LED strip

I'm wondering how to more efficiently power an IKEA LED strip (rgb, ~10ft long) I'm controlling with an ATTiny85. The LED strip has no controller because I used that for the first section of the strip I made into an infinity mirror. But not to let the rest go to waste, I've connected it through MOSFETs to an ATTiny85 and 24V 200mA ac adapter and that works well. So currently the ATTiny85 is powered by 3V battery source and the LEDs by the ac adapter. See attached image.
My question is can I somehow draw a small amount of power from the ac adapter to power the ATTiny from that and get rid of the batteries? I'm not at all an electrical engineer so don't know the first thing about doing that.
Thanks,
Erik

You can use any DC power source. Just buck it down to whatever your signal needs to be.

cool thanks!

@INTP thank you that worked, now I know something new!
