In this guide we'll show you how you can create a fun little physics based hourglass gadget. Hourglasses are used to track time, and this one ends up being sort of triangle shaped, so...yah, it's a Time Triangle Thing. This project was inspired by this awesome Instagram post by @david_proyectos.
We'll go over the underlying simplified physics model also. It could be a useful approach for some other gadgets. It's all written in CircuitPython.
Below we link to the specific hardware items used in this guide. However, the key ingredients are:
- A reasonably powerful main board that can run CircuitPython and has I2C
- LED matrix or matrices
Therefore it's possible to come up with potentially different arrangements. For example, an accelerometer breakout could be used with a non-Feather board. Or smaller LED matrices could be used, etc. Also, the battery can be whatever size you want.
