Found Hacks: 100% DIY Digital Picture Frame
Unlike the majority of picture frame hacks on the internet, this guide from Hack A Day teaches users how to build and program a digital picture frame from scratch. This is a great tutorial because it not only teaches the reader how to build the frame, but also teaches some useful functions like reading from SD cards, PIC programming, and working with common graphical LCDs.
“We set out to build a 100% DIY, scratch-built digital picture frame. Our frame has a 12bit color LCD, gigabytes of storage on common, FAT-formatted microSD cards, and you can build it at home.”
This project presents bit-twiddling and PIC programming in a more accessible fashion than many other tutorials on the net with a great end result.
