How to survive a grinder

An early version of the grinder is still out there.

One of its most interesting features is a system that takes a photo of the device and uses it to measure the power of its surroundings.

The device’s creators have dubbed the device “Grinding Evacuum.”

And they are hoping to build on the idea with a grimmer, grimmer version that uses a more powerful camera and can also measure power from its surroundings, as well as take measurements from the grinders floor.
