[vcf-midatlantic] Museum wireless doorbell thingamajig

[Jeffrey Jonas]

In this day of IoT, this could be a FUN project
Martin Flynn offered
> Waveware SPS-5 transmitter with 4 pagers.

That should be perfect! Pagers are retro.
4 of them mean some will always be charged and ready.

But the master station needs serial input from something.
Let's see

- a pushbutton to the Raspberry Pi
running the overhead video display,
which ought to have motion and distance sensors to react to folks automatically.
The "call button" could respond with a video - the cavalry is coming!
Or one of a random assortment of science fiction talking computers
such as the talking head from The Starlost or Red Dwarf.

- the big red button on the Cray

- setting the PiDP-8 console switches all "on"

- the Apple ][ serial port card.
Evans' Lego robot could entertain them while waiting.
For movie trivia, have it say "My name is Rags! Woof woof woof" :-)
