Gyroscope Level Is Digital | Hackaday

0

A spirit level, you know the kind of level with a little bubble in a tube of fluid, is a basic construction tool. [DesignBuildDestroy] took an Arduino, a gyroscope chip, and an OLED, and made a 3D printed level with no bubble, but it does have a nice digital display.

It is funny when you realize that at one time a gyroscope was a high tech item reserved for missiles and aircraft. Now you can grab a six-axis sensor for pennies. Even, better, the code used in the project can offload the Arduino for a lot of processing.

Initially, the device lived on a breadboard, which is always a good idea to get the kinks out of things. Thanks to the OLED, the Arduino can calibrate itself without a PC and do other tricks. The display is easy to read, but we thought there should be a mode that shows a little bubble made with an O character. Seems like that would be a fun rainy day project. We did like the automatic screen rotation, though.

We’ve seen a nice level done with a Raspberry Pi before. If you need something smaller, how about something the size of a dime?
