Imagine my excitement, then, to finally have a piece of equipment that could potentially depict how well a coffee grinder works in granular detail. Specifically, I’ve got a DiFluid Omni ($900), a new device that promises something heretofore unknown: the chance for home coffee geeks to graph out the particle size distribution of a batch of coffee. (It also has a colorimeter, to assess the lightness or darkness of a roast.)

As someone who likes good coffee this made me laugh. Wired is paywalled but it has good writers and interesting stories.
