3D-printed IoT lock box using ESP32
My eventual goal with electronics is to create autonomous robots and drones; I’d like to make a quadcopter with my own flight controller that can take off, land, and follow a target. This will be quite an ambitious project, and I’m nowhere near capable enough for that yet.
Previously, I created a simple plant monitor that reported stats to an online dashboard. This allowed me to learn soldering, stripboards, and 3d printing. To work on future projects, I need to be able to produce ever more complicated circuits and mechanical designs.
After watching some Lock Picking Lawyer on YouTube, I was inspired to think about different locking mechanisms. A locking box would be a good experiment with mechanical design, and if combined with IoT, would be good for electronics too.
In this article, I will cover how I created my lock box - from the problems I had, the iterations I made, and the final design I settled on. It’s a bit of a random project, I didn’t have set goals in mind. I started by exploring different locking mechanisms, and then moved to focusing on the electronics and getting it working.
