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.
The more paint you use, the more intense the color will be. You can also make DIY paints from acrylic paint ... glass to adhere it securely inside the frame, then hang it wherever you'd like.
