My house came with the doorbell wires buried behind the frame somewhere, so I installed a self-powered wireless doorbell. The transmitter harvests power from the user physically pressing the button, so it doesn't need batteries. I just caulked it straight onto the brick.

I removed the TECKNET logo with isopropyl alcohol. The receiver has dozens of tunes, but the only one worth using is the Westminster Chime Melody. There's also a "ding-dong ding-dong", but it's annoying that it plays twice. The rest are just too long; it's a doorbell, not a jukebox. The receiver remembers the tune and volume if power is interrupted, so that extra cruft doesn't matter after initial setup.
- 4star3star 3y agoI love this! Sometimes I daydream about a device that works kind of like an old printing press. You can arrange letter tiles to create a message. Then, you power the thing by pumping a lever or something, and it constructs a digital signal from the letters and sends it over something like LoRaWAN.
