I've created an auto-rotating digital billboard using a Raspberry Pi Zero W and a 3.5-inch touchscreen.
It's rough around the edges for now, but sanding and repainting should sort that out.
First an ad from our billboard "sponsor"
Another example of an advert.
Fully functional mini PC desktop too.
Finally, a shot showing the back of the billboard.
The ribbon cable will drop down through the platform and the baseboard, mounting the Pi on the underside.
Also included is a small pushbutton for safely shutting the Pi down when it is done with.
