Auto updating picture frame
The best digital photo frames cost between and 0 - the larger you go, and more extra features you choose, the higher the price.Make sure you choose the right aspect ratio: some digital picture frames come in a 16:9 or ratio rather than 4:3, which is good for landscape photos but not always for portraits.There are a number of different sized LCD monitors: This is a simple and inexpensive component that is responsible for turning the monitor on and off. You just need something that can hold a Raspberry Pi and monitor taped to it.The accuracy is great, as it never misses a beat, yet I haven’t found it to accidentally trigger in the night unless we walk by. I used double-sided mounting tape as an adhesive, although the wires are being held up by the frame itself.Digital picture frames don’t just let you show off your favorite photos in stunning high resolution.
Connecting the monitor was also trivial on a Raspberry Pi, where an Arduino, Maple, or Beagle Bone would require sourcing a connection between the monitor’s composite input and an output from the device.
The hard part for me was figuring out how to turn the monitor on and off through the command line.
Everything else is gravy, from configuring wifi and autoboot/auto-login on the device to attaching and setting up the motion detecting PIR sensor.
Also, consider the connection options: Wi-Fi is more expensive than a simple SD, micro SD or USB slot, but makes it incredibly quick to transfer your photos.
We tested a wide range of digital picture frames for over 50 hours.
