After recycling an old iPad Air, I thought I'd give new life to an old iPhone 6 as well.

I've removed its battery and followed this guide to make it work without it. I removed the SIM cage and used that slot to pass the wires to the BMS. Then I designed this case to hold everything together in a nice form. It makes for a nice clock, or music player, or Home Assistant dashboard, etc…

It requires 6 M2x12 (or longer) screws, along with their companion nuts and washers.
