Show HN: Coffee grind size chart generator

Ive a 270 and never gone much under 7 for espresso. Maybe ill try!

I use an oldschool hand-crank grinder. Can someone recommend a powered one that isn't too expensive? The coffee types I typically make are: turkish, V60, and french press.

This is pretty cool. I run a coffee forum and would love to have something embeddable I can post on my site.

I though the Niche could "do it all".
