Neat !!

Would it be possible for you to knock up a simple "how-to" when you have time, please.

The Apple dongle is a bargain at £9 delivered, I have a couple, and thanks to paul- they work on pCP

My latest portable but HiFi quality player.
Pi Zero W with pCP velcroed onto a Getihu power bank with Audioquest Dragonfly. I’ve been using it for about 6 hours so far and it’s used just 4% of the power. Started at 83%.
It fits into a small carry case. The power bank has an on/off switch and 2 USB out with separate USB-C that is both in and out.

No screen required as it’s controlled by my phone. Why not just use the phone? Both iPhone and Android carry compromises.

iOS. iPeng will play 24/96 happily with the Dragonfly attached but you need to use a Lightning to USB adapter. I’ve tried all sorts but the one constant is that they fail after a period of use. They require an Apple authorised chip in the Lightning end and it’s this that is the weak area. Also iPeng doesn’t support crossfade.

Android. Although the Android audio subsystem can handle 24/192 neither of the existing SB player apps seem to be able to use it beyond 16/48. Correct me if I’m wrong.

Well, the battery HAT never arrived from China, so went another direction, using a case and battery meant for gamers. Fun little project, if impractical. Haven't tested the battery duration, but expect an hour or two before it has to go back on charge. A magnetic micro-usb charger cable would make it a tiny bit more practical. No output at the moment, just a simple controller. The joystick is pretty nifty to use with the cap on.
