Building a high precision navigation gadget with simpleRTK2B

In previous updates we have given some figures about the accuracy of the simpleRTK2B board with u-blox ZED-F9P module.
We like to spend hours looking at logs and statistics about the performance of this module, but.. what can you do (in the real world) with this accuracy?

You can build a gadget like the one in the video and play the most high-tech treasure hunt in town with your kids 🙂
