Other than a guy with a cellar full of salvaged parts there wasn't much
local so it was mail-order from Lafayette or Allied. Then there was the
adventure when I was building a CD ignition (not a common thing in the
late '60s) and needed some ferrite cores. My cousin knew a guy who knew a
guy... and I wound up at a garage operation in Kingston. IBM always had
their eye on monopoly investigations so the backwoods of NY were filled
with cottage operations they had spun off.

Just for an alert? How far? I'd probably use a couple of Picos or even
Arduinos with nrf@$L01 modules.

The receiver in the how could blink LEDs, buzz, or whatever. For real sex
you could use neopixels for a pulsating rainbow effect.
