Event Quantifiers


Suppose you have connected a device to Artisan that measures the gas pressure of your burner or the setting of your damper. Wouldn't it be better to log this data as events reflecting changes on a 0-100% scale, instead of squeezing this data as a curve with a strange temperature scale in the graph?

Virtual Devices and Symbolic Assignments



Artisan supports a wide list of different devices to read data from and to write data to. Several of those devices can be operated in parallel ending up in more temperature channels than one can fit on the display. Could anybody need more?

Sampling Interval, Smoothing, and Rate-of-Rise


Let me try to explain my perspective on the processing of the raw data gathered from a temperature probe implanted into a coffee roaster. To understand what's going on in roast logging one has to look at the full chain of data processing from the probes to the screen. I assume here that all data is transmitted flaw-less from component to component and will especially avoid mixing this discussion with the spike issue as this can be treated separately.

Artisan 0.6


It took a moment, but now it is released:
Artisan v0.6 for Windows, OS X and Linux

Developing this version was a very exciting experience, because of all the enthusiastic support we received over the last year. We would like to thank especially the following people.

Monitoring a Londinium

The Londinium blog recently featured a box full of Amprobe TMD-56's ready to start a series of measurements on this machine that has been a bit of a rave recently. The guys at HG-One like it a lot, for instance.

Fighting Spikes


You might be one of the lucky roasters who gets perfect readings from your meter. However, some don't. Mostly spikes are caused by some electrical interferences between the temperature probe, meter or Computer. In the ideal word those should be resolved by an improved hardware setup. A nice description of the issue and a documentation towards its solution was recently posted to the HomeBarista forum. However, in some cases a physical solution is not possible for various reasons. In those cases the new spike removal features of Artisan might help you out.
