This wraps up all the videos I needed to make to describe every espresso accessory I've made in the past 3 years.
It's a bit strange that I put all this energy into making a new product, and then don't find the time to explain it.
On a separate topic...
I have two new accessories currently in development:
1) a "pour over basket", to help you make V60-style pour-overs with your espresso machine. I'm working with Scott Rao on this. The goal is to create the right spray angle, and the right amount of turbulence. Our current prototype has 11 calibrated holes in a blank portafilter basket.

2) a puck simulator (essentially, a blind basket with a calibrated laser-cut hole)
And I'll post news about them here, when I've made progress on them. The "puck simulator" is ready to go, but I don't expect it'll be a "big seller", so I'm waiting until Rao is happy with the "pour over basket" and will make the two of them at the same time, since they're variations on each other.
