Artisan v2.8.4


We introduce Artisan 2.8.4 which adds a few features and improves stability while staying full compatible with any previous version.

Buttons – Appearance, State, and Action

A custom button in Artisan is specified by a name, an event type and value, an action as well as button and text colors (see Events, Buttons Palettes). There can be as many buttons as you like. Additionally, each button has an appearance (normal/pressed) and a state. State and appearance are disconnected by default, but can be connected via button actions.

Understanding Roast Color

Taking the color of a roast is quite simple nowadays. Just prepare a sample and point your roast color meter at it. The device will display the roast color as a number. This may raise some questions.

  • Why do different devices report different results on the same roast?
  • What does the reported number mean and how does it compare?
  • Why does the same device report different numbers for the same roast?

This post resembles our report On Idle Noise, where we identified the sources of temperature measuring noise and quantified their impact. This post shares our observations from over 1000 color measurements taken with Tonino and Lighttells CM100+ roast color meters. Our results can help answer the above questions and may lead to better color measurements.
