Artisan 2

Here is artisan 2!

Using Artisan Designer

An excellent video by Alan demonstrating how he uses the Artisan designer to develop roast profiles. 

Thanks for sharing!

How to document sampling?

Someone just asked how to document the moments she takes samples mid-roast using the tryer?

How close?

Ever wondered how close you duplicated a previous roast profile? A standard measure in statistics to express the average error between a curve and its target is know as Mean Squared Error (MSE) which computes the average of the squares of the single discrepancies between the data values and their targets.

weight • volume • density

Knowing the density of your raw beans is key to adjust your roast profile. Knowing the density of roasted beans is important for successful blending. Keeping the bean density of a product constant helps to keep your customers happy.

Keep an eye on the delta!

Once you have developed a profile for a coffee you want to precisely duplicate that one in future roasts. Artisan allows to load this successful profile in the background serving as a template for your production roasts. While seeing the delta of your current roast curve and that template helps you to decide if you should slow down or speed up your roast at any moment, especially if zoomed into the graph somewhat. However, often a numeric value expressing this delta is easier to work with. What about adding another LCD to show this delta?

On Idle Noise

This note describes how I improved the measuring system of my roasting machine to get more accurate roast profiles, like the one shown above. I got motivated by the work of Scott Rao.

Artisan v1.6.1

It is our pleasure to announce the release of Artisan v1.6.1. Many issues have been resolved and many suggestions, reported via the Artisan Issue Tracker, have been implemented.

Running Artisan on Raspberry Pi

This post describes how to install Artisan packaged releases and Artisan source on the Raspberry Pi. The process has been tested on the RPi 2B, RPi 3B,and RPi 3B+ but should work for on any RPi running Raspbian Stretch.

Artisan @ WOC 2018

Thanks to the support of Frans from Kostverorenvaart and Arnoud from the Vintage Espresso Machine workshop I am happy to announce the first Artisan community meeting!

Update: Frans was so kind to post some pics of the event on home-barista.com

Artisan v1.3.1

This version of Artisan is mostly a bug-fix release, resolving many minor issues reported by users since the release of v1.3 about a month ago.

Automating a Huky

Here I give a short insight in my roasting setup, detailing how I connected my Huky 500T using VINT Phidgets and some custom electronics to Artisan.

Artisan v1.3

Artisan is getting simpler! Simpler to find, simpler to install, simpler to setup, simpler to configure and simpler to use. Artisan v1.3 is also extending its scope by adding direct support for 16 roasting machine brands and gets more beautiful by adding color themes. However, the biggest news is on its growing team.

Artisan v1.2

Artisan v1.2 is a major release. The software on which Artisan is built was significantly modernised, especially on the Windows platform, resulting in better support of the current operating systems and hardware (e.g. high-resolution displays). A consequence of this move is that from now on, only 64bit operating systems are supported and compatibility with Windows XP and OS X before v10.10 has been dropped. Find below a description of the major changes and new features.
