Coffee-Tech FZ-94 working seamlessly with Artisan

Recently, we received the opportunity to get an FZ-94 lab roaster and see how this roasting machine could work seamlessly with Artisan. An inspired back-and-forth between Marko Luther on the Artisan side in Germany and the R&D team of Coffee-Tech in Israël ensued and soon, the first machine was communicating fully with a newly expanded and freshly compiled version of Artisan.

Artisan v0.9.9

A number of productivity features have been added on request to this version. The ones that might be of interest for a wider audience are described below. For other more specific addition and bug fixing see the change log.

Roast Calculus

This post is going to review the subject of roast calculus. This calculus is about change and motion. Everything is dynamic. Measurements of changes are vehicles for understanding a wide spectrum of physical processes. Knowledge of the universe comes from observations of changes and not from static measurements. We use calculi in real life every day. In a car for example, the speedometer measures a rate, the speed. The odometer integrates the speed over time, the distance, and the foot pedals control the acceleration, rate of speed.

LCDs

Alternatives for displaying the roast time, bean temperature (BT) and environmental temperature (ET) have been added for those, fighting with small screen sizes on their main roasting computer, but having a secondary screen available.
