Coyt Barringer has been working on a programmable VFD display and ticker project:
The goal was to make a small programmable display so I can quickly check the current Bitcoin or Dogecoin price, see the time, weather, etc as I walk into my room. The display also had to look cool – I tried to make it steampunkish / hipster if you will.
The whole thing is really just a large VFD (Vacuum Fluorescent Display) and a Raspberry Pi, both of which I mounted to a bent metal plate as a stand. There is also a PIR motion sensor which I have setup to put the display to sleep after a set amount of time with no motion in the room. There are green LEDs between the metal plate and the back of the VFD to create a green glow around the edge. The Raspberry Pi is running it’s default debian distro (Raspbian?) and auto connects to wifi on boot, and a Python script controls the VFD through the Raspberry Pi’s serial port.
