Fun with vacuum fluorescent displays
Liquid crystal and OLED displays have taken over the world, but before this happened they coexisted with Vacuum Fluorescent Displays (VFDs), you know, those nice displays that shine spooky blue or green instead of backlit black on an ugly greenish background. How about using such a VFD with a Raspberry Pi in a connected kitchen radio project?

After his old kitchen radio broke down, the author of this project took the time and opportunity to recycle its display, a Vacuum Fluorescent Display (VFD). Together with a Rasberry Pi he planned to build a new kitchen radio with a clock and a timer for baking & cooking. An ATmega32 would control the display and the buttons, while the RPi would function as internet radio (and later perhaps do even a bit of FHEM home automation too).
