Artisan Phidget - Plug and Play weatherstation

-

(Also: https://artisan-roasterscope.blogspot.com/2018/10/artisan-v140.html)

When roasting coffee, I like to know and remember what the ambient conditions are, so I can later compare roast profiles and bean behaviour over different seasons.

Until recently I used a "Eve" device from Elgato and its app on my iPhone:

Eve Degree device, by Elgato

Data from Eve degree, showing room temp, moisture, pressure

Initially I wrote this data in the Title of Bean fields of the  "Roast Properties", then Marko Luther created dedicated fields to enter this information so it would be displayed after the roast.

Now, Marko has further expanded Artisan to read these data fully automatical, at startup, from Phidget modules.

To get this up and running, Marko sent me this shopping list:

- a Phidget VINT HUB (https://www.phidgets.com/?tier=3&catid=2&pcid=1&prodid=643)
- a Phidget VINT HUM1000 (https://www.phidgets.com/?tier=3&catid=14&pcid=12&prodid=644)
- a Phidget VINT PRE1000 (https://www.phidgets.com/?tier=3&catid=64&pcid=57&prodid=719)
- and 2x VINT cables (as suggested on the order pages of the HUM1000 and PRE1000 modules)

Plus download and install the Phidgets v2.2 driver for Mac OS X from their pages.

I expected some trouble in assembly, or at least in configuration, attempting to actually make the Phidgets talk to the laptop and Artisan, but it turned out to be dead simple, a matter of unpacking, clicking in, connecting, and starting.

Artisan now requests, at START, the ambient values from the Phidget sensors. So it's a good idea to make sure the Phidgets hub is connected to your computer before clicking START in Artisan. One can also update/refresh the ambient data at a later time in the Roast Properties menu.

Shipment in the box arrived

Unpacked, ready to click in the wires between the modules and the hub

Stuck the modules and hub on underside of the table near the roaster, using 3 blobs of yellow Sugru
Phidgets hub USB to laptop Artisan already recognized the parts

Clicked "update" to read the new "Ambient Conditions" values instead of the ones I had manually entered

Tiny Cheap Fluid Bed Roaster by Tije and Jan

(also see Daily Coffee News feature ) Tije designed and made the following structure for a tiny and cheap fluid bed roaster, to which Jan van der Weel added the Arduino parts, electronics and programming: Sketch by Tije de Jong Jan sourced a very cheap blower (€ 11) to start with, Tije developed and constructed the mechanics, Jan built together and programmed the TC4 / SSR electronics.  On his blog, Jan will specify exactly how the TC4 part is combined and programmed and I will copy these details into this blog entry, just as Jan will use this video in his blog. We did a few test roasts to make sure it works at all and it does. Towards the end, the first roast tended to get a flat BT line and airflow was slightly decreased. 200g seems max load of green beans. Second roast a little more power was given to the heater. Next we will try the Background Roast driven by the PID software of Artisan. A week later, with updated software that works better to change the fan

Finished Pavoni & Fuji PXG4 pid: Probe Inside the Ring

Delicious cup: all the work was well invested! At the end of the previous blog about the pressostat and PID working together , I mentioned that I would like to clean up the xmas tree of wires and have as few cables and probes as possible to visually disturb the classic design of the La Pavoni. Getting rid of the probe that was fastened with copper tape to the top of the brew group was a priority. I wanted to hide a new probe in the cooling fin as close as possible to the brew group. This morning I asked Tije if he could do that. He would need to drill a straight hole of 3mm diameter in the 4mm inner ring of the cooling fin that sits as a tight clamp around the brew group. Always the optimist, Tije set to work: First, Tije made a piece of aluminum to fit the inside of the ring. Drilling a thin hole straight through the curved aluminum, if possible tangentially going through the inside of the ring to touch the brew head directly, you need the support of the temporary insid

TC4+ boards and Arduino controlled roaster by Matthias Gerstgrasser

illustration by Matthias Gerstgrasser On the mailing list for Artisan users , Matthias Gerstgrasser posted a report about his coffee roaster project, with a link to a beautifully illustrated, complete step by step guide of his work on Instructables: A while ago I posted a few messages on here regarding automation for my hot-air popcorn roaster, and was asked if I could share a writeup of what I had been doing with my setup. I know it’s been a long time, but I haven’t forgotten, just got a little sidetracked (more on that below). I have finally found time to do this over the last few weeks though, and compiled a step-by-step guide of how I modified my popcorn machine. This is now available on Instructables: https://www.instructables.com/id/Arduino-controlled-DIY-Coffee-Roaster/   Do let me know if there’s anything missing or anything that could be improved. I intend to keep updating the guide as I find ways to improve it or as new developments occur. I am also discussing b
