Smart Useless Box with ESP8266 and Gesture Sensor

myminifactory

This is a project for a highly advanced useless machine built using an ESP8266 microcontroller on a Wemos D1 Mini board paired with an APDS-9960 proximity sensor to create more humorous responses. Smart Useless Box in Action: https://youtu.be/x0kGetj1nt8 YAUB (Yet Another Useless Box)? Useless machines are not new inventions, there are many versions available. You can build a simple one using a lever switch, however that will react consistently every time. Using a programmable microcontroller you can create unexpected and funny responses, and by adding a proximity sensor you can surprise the user with actions before they even turn on the switch! This is a fully programmable useless box, so you have the option to implement additional reactions whenever you want to further improve this humorous little toy. What's more, the used controller board has WiFi connectivity, allowing you to connect it to other online services (e.g. IFTTT) or smart assistants (Alexa, Cortana etc.). How to Print This Rotate the lid parts to print them upside down. That way you don't need any supports and you can get a nice surface finish. You can safely print all parts with 0.2 mm layer height, without any supports. How I Designed This I used Fusion 360 to design all parts of this machine, and I continuously kept 3D printability in mind, so: no supports are needed to print the parts, 0.2 mm layer height is more than enough, so you can print fast, no additional details necessary, only M3 screws are required which are common for 3D printers. Feel free to download the attached STEP files and customize this project for your needs!
