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.

Die Erste Deutsche SCAE Röstmeisterschaft 2015

The first German SCAE coffee roasting championship took place last week on 26-28 October @Probat in Emmerich. The competition followed a slightly simplified, but authorized, version of the 2016 rules and regulations of the World Coffee Roasting Championship (WCRC) to select the candidates to compete next year in Shanghai for the world mastership.

Increasing the Heat

Up to Artisan v0.9.7 custom event buttons could only set absolute event values. The version 0.9.8 adds the possibility to define buttons that increase or decrease an event value relative to the last one registered.

Natural Roasts

People typically talk about the art of coffee roasting. We're interested in the science. Therefore, we keep adding features to Artisan that allow to analyze and compare roasts. Here we want to introduce our latest observation and the tools now available in Artisan v0.9.8 to play with the underlying idea.

Signals, Symbolic Assignments and the Plotter

Symbolic assignments are mostly used to adjust readings coming from connected devices or to define so called virtual devices. In this post, Rafael Cobo will get you familiar with the extended symbolic assignments he just implemented for the plotter in Artisan v0.9.8.
