General Purpose Wi-Fi Donger (Actuator)

thingiverse

This gadget connects directly to your Wi-Fi network and then you can trigger it with a web browser. I built it to ring my bell, but you could use it to ring something else, push something, or pull something... You get the idea! It's fully customizable through the web interface, where you can set the position, length, and pause for each stroke. Your settings will be stored on the device, even after a power outage. To build this gadget, you'll need: 1. HiTec HS-422 Deluxe servo or similar 2. WeMos D1 Mini R1 microcontroller 3. WeMos Power Shield (unless you have a better way to power your D1 mini) The WeMos components come as kits and require some soldering skills and tidy wire connections. Since WeMos microcontrollers are compatible with the Arduino dev environment, if you know how to program an Arduino, this will be a breeze. Just configure your WiFi password in the code before compiling. Once it's up and running, try reaching the device at http://dong2.local . If that doesn't work, check your router for its IP address and use that instead. This gadget requires 5-8V DC @ 0.1 A power supply or better. The chip in the WeMos D1 is pretty power-hungry when connected to WiFi - not really suited for long-term battery operation. Check out my YouTube video on how it works: https://youtu.be/TKgYVtJK7vQ
