I’ve came up with some new ideas for the Photo Frame Management GUI.
It will be able to mange the eink email account cresdentials, display saturation level, photo display time, time interval for fetching new photos by email, upload and download photos, cpu max low frequency. I want to add username and password encryption next. The photo frame email account and password will all be encrypted in a hash. When I get it to the point where encryption is added I’ll create a debian installer package. I moved the cron job to system cron in /etc/cron.d since it’s easy to deliver with the debian package.
The photo frames I used are here:
When installing don’t use the glass plate.
After I get the debian package delivery built I’ll design a back panel for the frame.
I’d like to use the rpi UPS board to power this frame. I’m still looking for one that has
an RTC and is arduino based. It might be the Witty Pi 3 or Sleepy Pi. The best solution might be a RPI UPS board with arduino, RTC, and usb connectivity … not sure yet. I started a battery test with a full charge. Will the getmail.py running every 5 minutes and photos updating once per minute battery usage has been higher.
24hrs and 25% power used so far. If I throttle down the cpu to a lower frequency than what I am using right now when idle I might get more time. Also maybe check for new photos by email once every 15 minutes and present each photo for 10 minutes.
I figured what I am testing now is worse case.
I have another display coming in. Chicago Electronic Supply had them… so I am building another photo frame.
