You've managed to pack a lot of alpha characters into the small flash memory (32KB) of the ATMEGA328. Very nice display setup. Does it have a timeout to shutoff, if left on? Is the RAM preserved if it shuts off? Is there an ON/OFF switch? What? No serial port/SD card to upload/download programs??! (just kidding). Nice design!

All parts are through hole, so it's easy to solder.
Everything is managed by the ATMEGA328 (no other chips are involved)
The display is a standard SPI 192x64 LCD.
It does have auto-shutdown timer (and the time can be changed on the settings screen)
It also has backlight and auditable feedback (speaker)
Ram is preserved.
I'm working on a new design with serial communication and on a 3d printed case.
