Stumbled upon this a few months ago and loved the idea. Followed the DIY guide and used all the recommended parts (bluetooth, wifi, SD card, usb drive, etc). Installation was smooth. Just plugged the parts in. Didn’t need any drivers or anything. I used the official Pi 5V 2.5A power supply so I didn’t have any power/no-boot issues that some had mentioned in the forums. In case you were wondering, you DO need the bluetooth adapter. The frame mostly uses wifi to do things, but on the first boot up, you’ll need to enter the wifi network password which gets passed from your phone app to the frame by bluetooth.
This frame is amazing. Thanks so much for creating and sharing this. Hope all is well and best wishes!
