ROR, filters, sampling, over sampling, etc
by Fred B
I've been using the Artisan program for some time now on an Ambex ym2 with
an Omega data logger and a 2 ghz dual core laptop. I just loaded 0.8 and
I'm hoping that I might get smoother ROR values with this version as I see
that is one of the improvements. Maybe the issue is the fast response of my
probes? Is there a way to compensate for this in Artisan? Can you make
some recommendations as to the EXTRA settings for the newer version and
maybe something up to date about the effects of using values too large or
too small? My ROR just jumps around too much and by the time it's
dropping/rising too rapidly it's almost too late for me to do anything about
it. Could I benefit (or not and why) from using over sampling or a higher
or lower sample rate? I'm at 4.0 now. Which curve smoothing values affect
real time displays and which don't? I've been reading Scott Rao's new book
and find myself evaluating my roasts and looking carefully at ROR and 1st to
drop percentages so Artisan is so useful. Thanks so much to all that have
contributed to this great program.

Hottop 2K+ display of Fan and Heater settings
by Michael Rasmussen
Hello All,
I've a freshly upgraded to 2K+ Hottop and freshly installed Artisan 0.9.8
While getting the installation all worked out I've been running beanless roasts.
When I have the heater power below 50% or the fan control below 5 the Artisan interface shows -1 rather than the actual value.
As soon as the fan or heater is raised above those thresholds the LCD displays an accurate number.
What clues do you have for fixing this?

Re: [Artisan-user] First Observations and Questions from a Linux install for Hottop 2k+

Hi.
Usb serial ports do not exist until the usb device is plugged in. They are created dynamically. The name is determined by the operating system.

Michael,
I also use Linux w/ Artisan. Not sure if Arch uses udev, but I fixed
my debian based system so that every time I plug in my probe, I get a
consistent device name to use. The problem is basically when you
attach your serial device, whatever it may be, sometimes it shows up
as /dev/ttyUSB0, and sometimes ttyUSB1 or something else. I am not
sure what determines this naming, but I have seen it vary, and even
change on the fly. The solution is to add a udev rule that creates a
symbolic link with a constant name to point to the actual device. In
my situation, I added a file called /etc/udev/rules.d/datalogger.rules
that contains this:
ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6001", GROUP="plugdev",
SYMLINK="tmd-56"
This tells udev to create a symbolic link "tmd-56" to point to the
real device file. You can use the 'lsusb' command to easily find the
vendor and product ID for your device. Then I just simply tell Artisan
that my serial port is /dev/tmd-56 and it always finds it, no matter
if the probe is plugged in before or after starting Artisan. You may
need to customize the plugdev group also for your distro and add
yourself to the plugdev group. On some systems the "dialout" group is
used for serial devices.

First Observations and Questions from a Linux install for Hottop 2k+
by Michael Rasmussen
Some general observations and questions after my first day with Artisan
on Linux controlling a Hottop 2k+
Observation
If the Hottop is not connected via USB when Artisan is started the serial port
is changed to __something__. No communication with the Hottop is possible. It
seems this config will persist after plugging in the Hottop. (need to confirm)
No errors are reported, even after clicking the Start button. So there's no
feedback to the user about the misconfigured state. This might lead to "it quit
working" problems.
So note to self: always plug in the Hottop before launching Artisan so the correct interface is found.
Good News
Support for the FTDI has been part of the Linux kernel since version 3.5, mid 2012, so no driver installation needed.
Observation
I can control all sorts of bits on the Hottop, but not its buzzer. Seems that's not supported by the Hottop API. Shame, it would be good to create alarms that trigger it.
Documentation Bug and Question
In http://artisan-roasterscope.blogspot.de/2015/05/hottop-kn-8828b-2k.html
Section 4.2 the illustration does not match v0.9.8 of the software.
[sorry if you don't have a fixed width font for the following]
The illustration shows [x] Button [x]Show []Mini Editor Bars[set to Value]
The software shows [ ] Butten [ ] MiniEditor [ ] Annotations [ ] Events Bars[Set to Value]
Mini Editor? What's that? Annotations?
These aren't covered in the docs, so they'll be covered in exploring.
Observation
The documentation link goes to an article from 2013.
Question
Do you have notes on how things work? Have you shared them here?
Is there a general Wiki for people to weigh in on what they've learned?
Bottom Line
Oh wow, what a great piece of software. A pleasure to use.
Despite the above I was able to load it on an unsupported platform (Arch Linux) and with just a bit of work control my Hottop. Nice.

Roast Report window pops up and disappears immediately
by Michael Rasmussen
When I select "Roast Report" from the File menu a window with some graph pops up and then immediately disappears.
Is there some configuration required prior to using this feature?

Re: [Artisan-user] Auto DROP not working
by Susan
Not a stupid question. I went out and double checked on the laptop I
used for roasting and it looks just like this.
I have added the DROP button back and can use that; and/or I can go
back in and put it in manually; I just wondered if this was happening
just to me ...

Auto DROP not working
by Susan
Is anyone else having trouble with Auto DROP?
I have had to add the DROP button back because somehow it never
registers automatically anymore.
I am not clear when it stopped, but I suspect since the lastest upgrade ???
Sorry I can't be more helpful about that.
AutoCHARGE works. AUTOTP works. Just not DROP.

Keyboard shortcuts for buttons?
by Martin Diers
I did not find archives for the list, so I apologize if this has been asked before.
Is there any way to configure keyboard shortcuts to correspond to the buttons used during a roast?
In particular, I would like to be press a key for Charge, FC, SC, and Drop.
Occasionally, I am trying to click Charge and I miss, which, of course, means I have a time offset. I know I can reposition my background (and do), but I'd not as likely miss if there were keyboard shortcuts..
Thank you,
Martin Diers
