We need to have a talk how we can realign our interests and bonds within the hackerspace. For this, we're organizing a meeting where we can openly talk about the future.

To make this talk as efficient as possible, I'd like everyone that attends to think about the following things:
* How can we fix the internal issues we're having
* How do you contribute to these issues, and how can you fix them?
* What kind of things do you think that Bitlair needs in order to prevent cq minimize these issues from happening

Since this talk is going to pull up a lot of old sore from a couple of people, It's vital that *all* of you come in peace and be respectfull to each other during the talk. We do not want any mudslinging, we want to make Bitlair a better place for *all* of our members.

= What =
Since we want to build a lot of really big fires this summer, we need lots and lots of fuel, preferrably dry (and free as in beer) wood. Since wood only returns heat on investment, we need to pool money ourself to pay for wood and arrange our own transport.

= How =
# We find wood somewhere
# We arrange transport
# We pickup the wood and bring it to bitlair
# ... PROFIT!!11oneeleven

= Resources =
For transportation, we will need someone with a towbar so we can hookup a trailer. If you've got a car with a towbar and are willing to drive to pickup wood, please add yourself to the list below. If we cannot find someone with a trailer, we can rent one (See money pooling). If you pay for fuel (instead of your boss), add it to the list and make sure you specify the maximum distance you would be willing to drive or if you want to be reimbursted for the costs.

R3boot: /* Hanging main unit */

{{Project
|name=Weatherstation
|start=2011/09/01
|URL=https://r3blog.nl
|contact=User:R3boot
|info=An arduino powered weatherstation
|status=Test
}}
Using an arduino together with a couple of sensors, I've created a weatherstation. This page contains (or should contain) all required info to use and maintain this system.

== Overview ==
This weatherstation is based on an arduino pro mini, which has seven different (mostly analog) sensors connected to it. The arduino talks to a soekris over a RS-232 line, which has been modified on the soekris side to provide +5v over a spare wire to provide the arduino with power. I've inserted an PNP transistor inline with this +5v line which is coupled to a GPIO pin on the soekris, providing remote reset functionality. The soekris runs a C application to read the data from the secondary serial port, aggregate it and distribute the aggregated values to both a file-based datalogger and graphite.

== System Diagram ==
TBD

== Source Code ==
The source for this system consists of two parts. One part that is running on the arduino, and one part that is running on a soekris.

* weatherstation (to be run on the arduino) https://github.com/r3boot/weatherstation
* weatherd (to be run on the soekris) https://github.com/r3boot/weatherd

== Graphs ==
For now, there are some rudimentary graphs available on stats.bitlair.nl. This is subject to refinement and recalibration in the future. Also, the namespaces for these graphs may change. To see these graphs, follow the link below:

* graphite based: https://stats.bitlair.nl/dashboard/weatherstation
* graphene based: http://weather.as65342.net/realtime.html

== Bugs ==
=== Segmentation fault (core dumped) ===
The server-side code hasn't been finished yet, and sometimes segfaults. To fix this, I'm running weatherd in a while true loop until I've fixed the code. Furthermore, since weatherd doesn't startup automatically, it needs to be restarted after each reboot or poweroutage. Both zarya and myself have root rights on this box, and can run the following commands (as root) to startup weatherd:

<tt><pre>
# tmux attach
</pre></tt>
or
<tt><pre>
# tmux
</pre></tt>

followed by:
<tt><pre>
# cd ~r3boot/weatherd
# ./weatherd -v -g stats:2003:weatherstation
</pre></tt>

Furthermore, I'd like people to save the coredump for future analysis. For this, please run the following command:

<tt><pre>
# cd ~r3boot/weatherd
# cp weatherd.core weatherd.core.`date +%d%m%Y%S`
</pre></tt>

=== Hanging main unit ===
I've also seen that the main unit might crash every now and then. Symptoms are either no values, or a continuous identical value. To verify, stop weatherd (see the above explanation), and check the serial port to see if there is any difference and/or variation in the pattern of values. To do this, run the commands below. Please note that I've added a check in weatherd that will reset the main unit after we've received the same checksum 5 times.

<tt><pre>
# cu -s 57600 -l /dev/tty01
</pre></tt>

Normal output looks something like this:

R3boot: /* Hanging main unit */

{{Project

|info=An arduino powered weatherstation
|status=Test
}}
Using an arduino together with a couple of sensors, I've created a weatherstation. This page contains (or should contain) all required info to use and maintain this system.

== Overview ==
This weatherstation is based on an arduino pro mini, which has seven different (mostly analog) sensors connected to it. The arduino talks to a soekris over a RS-232 line, which has been modified on the soekris side to provide +5v over a spare wire to provide the arduino with power. I've inserted an PNP transistor inline with this +5v line which is coupled to a GPIO pin on the soekris, providing remote reset functionality. The soekris runs a C application to read the data from the secondary serial port, aggregate it and distribute the aggregated values to both a file-based datalogger and graphite.

== System Diagram ==
TBD

== Source Code ==
The source for this system consists of two parts. One part that is running on the arduino, and one part that is running on a soekris.

* weatherstation (to be run on the arduino) https://github.com/r3boot/weatherstation
* weatherd (to be run on the soekris) https://github.com/r3boot/weatherd

== Graphs ==
For now, there are some rudimentary graphs available on stats.bitlair.nl. This is subject to refinement and recalibration in the future. Also, the namespaces for these graphs may change. To see these graphs, follow the link below:

* graphite based: https://stats.bitlair.nl/dashboard/weatherstation
* graphene based: http://weather.as65342.net/realtime.html

== Bugs ==
=== Segmentation fault (core dumped) ===
The server-side code hasn't been finished yet, and sometimes segfaults. To fix this, I'm running weatherd in a while true loop until I've fixed the code. Furthermore, since weatherd doesn't startup automatically, it needs to be restarted after each reboot or poweroutage. Both zarya and myself have root rights on this box, and can run the following commands (as root) to startup weatherd:

<tt><pre>
# tmux attach
</pre></tt>
or
<tt><pre>
# tmux
</pre></tt>

followed by:
<tt><pre>
# cd ~r3boot/weatherd
# ./weatherd -v -g stats:2003:weatherstation
</pre></tt>

Furthermore, I'd like people to save the coredump for future analysis. For this, please run the following command:

<tt><pre>
# cd ~r3boot/weatherd
# cp weatherd.core weatherd.core.`date +%d%m%Y%S`
</pre></tt>

=== Hanging main unit ===
I've also seen that the main unit might crash every now and then. Symptoms are either no values, or a continuous identical value. To verify, stop weatherd (see the above explanation), and check the serial port to see if there is any difference and/or variation in the pattern of values. To do this, run the commands below. Please note that I've added a check in weatherd that will reset the main unit after we've received the same checksum 5 times.

<tt><pre>
# cu -s 57600 -l /dev/tty01
</pre></tt>

Normal output looks something like this:
