Story I heard was that the ballast was shot and needed replacing. I
couldn't find the ballast with a 30 second inspection, but it's in
Anyone interested should open it up and take a look inside. The front
"plexiglass" (acrylic I think) is not transparent as the "poster" is
silkscreened onto the back and is not easily removed without ruining
the plastic. Note that the drinks are still behind an insulating panel
and would not be visible even if the front was transparent.
However the entire plastic front panel could be replaced with clear
acrylic or something else similarly flexible. There's plenty of space
for a flat panel or an LED array behind it. TAP Plastics will cut
things to size given dimensions; I think they could even handle the
notch for the drink slot.
Drink inventory is another project for over-engineering; a few optical
sensors and an MCU could count cans leaving the machine. With a Chumby
or similar Linux board we could put the sucker on the internets with
a web interface for seeing the current inventory and refreshing the
count when restocking.
I think I actually promised to do this...
