When the bubble is in the center of the tube, the device is level in the direction of the tube. [Mark Williams] has a slightly more involved approach. He took an internal measurement unit (IMU) and a Raspberry Pi to create a modern take on the spirit level . The device shows virtual spirit bubbles on an LCD using some Python libraries. You can see a video below and find the code on GitHub . We’ve certainly seen more exciting uses of IMUs . We’ve even looked at some tiny IMUs, if you want to go smaller.
