I worked at an e‑waste center in the early 2000s that eventually shut down, and as a result still have roughly 50 pounds of old pagers in various states of disrepair.
One of my personal chindogu ideas (someday) is to wire them all up so I can control them from a phone app, then strap them to different "meridian points" on a customer to deliver an authentic beeper massage experience.
Check for Gold Apollo AR924 first before powering up...
