Anyone measures roast colour? I’ve used a tonino colour meter for a little bit, and besides volume and weight measurements, colour measurements add a bit more data to your roasts.
So made this roast meter based off: https://github.com/juztins-lab/roast-meter (seen on a HB thread. It’s not very hard to make and components cost around £100. Printed 4 cases, so I have 3 left if anyone wants to build one.
Seems to be quite consistent in measurements, using NZ on turkish coffee setting of 1.
