What better way to ring in the new year than with [iSax Laboratories]’ charming little project that replaces a doorbell with a Maneki-Neko cat figurine to ring a physical bell?
Details are unfortunately a bit light, but it looks like the Maneki-Neko cat was disassembled to allow for a small SG92R servo motor to attach to the arm pendulum mechanism. [iSax Laboratories] added wooden platform where the Maneki-Neko cat figurine is mounted along with some indicator lights, switches and the physical bell, with a cavity routed out in the base to allow for the Arduino Nano microcontroller.
[iSax Laboratories] has what looks to be an Assa Abloy Svara 23 wired answering machine, which has one of its output lines connected to the Nano to sense when a doorbell signal has come in.
The Maneki-Neko cats are cute, easily hackable figurines and we’ve featured them in the past, using them as everything from hit counters to POV displays.
Be sure to check out the demo video after the break!

Isolated as we are by national lockdowns and statewide stay-at-home orders, many coworkers are more connected than ever before through oddly-named productivity/chat programs such as Slack. But those notifications flying in from the sidebar all the time are are oh-so-annoying and anti-productive. Ignoring requests for your attention will only make them multiply. So how do you make the notifications bearable?
[Mr. Tom] wrote in to tell us about his solution, which involves a maneki-neko — one of those good luck cats that wave slowly and constantly thanks to a solar-powered electromagnetic pendulum. Now whenever [Mr. Tom] has an incoming message, the cat starts waving gently over on the corner of his desk. It’s enough movement to be noticeable, but not annoying.
An ESP32 inside the kitty looks at incoming messages and watches for [Mr. Tom]’s user ID, prioritizing messages where he has been mentioned directly. This kitty is smart, too. As soon as the message is dealt with, the data pin goes low again, and the cat can take a nap for a while.
The natural state of the maneki-neko is pretty interesting, as we saw in this teardown a few years back.
