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. > Looking at building a small FM transmitter wired to my mail-box. > Being right at the road, and a bit away, it's useless trying to do > image-ID and there is no hope of getting power out there. Just for an alert? How far? I'd probably use a couple of Picos or even Arduinos with nrf@$L01 modules. https://howtomechatronics.com/tutorials/arduino/arduino-wireless- communication-nrf24l01-tutorial/ and a PIR to detect when the box was opened. https://learn.adafruit.com/pir-passive-infrared-proximity-motion-sensor/ using-a-pir-w-arduino The receiver in the how could blink LEDs, buzz, or whatever. For real sex you could use neopixels for a pulsating rainbow effect. https://www.adafruit.com/category/168
