1) Message boards : Number crunching : Problem - cannot view my data in Trickle (Message 3366)
Posted 2686 days ago by Profile jhelebrant
I do not understand it - I did:

juhele@Hosaka-Cyberspace7:~$ id boinc
uid=124(boinc) gid=139(boinc) skupiny=139(boinc),44(video)
juhele@Hosaka-Cyberspace7:~$ sudo adduser boinc plugdev
[sudo] password for juhele:
Přidávám uživatele „boinc“ do skupiny „plugdev“…
Přidávám uživatele boinc do skupiny plugdev
Hotovo.
juhele@Hosaka-Cyberspace7:~$


Boinc was added to plugdev group without problems, but my last task looks again this way...

http://radioactiveathome.org/boinc/result.php?resultid=5364892

I will try to purge boinc again and install their own package and not the one from repository.

OK I corrected it but still does not look good:
http://radioactiveathome.org/boinc/result.php?resultid=5352706

Will try few more tasks to see whether anything changed...

This is strange. I put "53-radioactive.rules" in /etc/udev/rules.d, file contains the code based on suggestion found in mentioned discussion threads:

#r@h
ATTRS{idVendor}=="16c0", MODE="666", GROUP="plugdev"
LABEL="radioactive_rules_end"


And I rebooted my machine and also because of some problems I had to purge Boinc and install it again.

However I am still getting those messages:


Stderr output

for my tasks...

Did I something wrong? The file has the same permissions as the other ones in /etc/udev/rules.d

PS: also tried running Boinc as root but no effect...

Hi,
after some time I managed to plug in my sensor to measure again. I have the BOINC manager from Ubuntu repositories and all looks OK - however I cannot view my data.

My Computer ID is 15811, but if I use:
http://radioactiveathome.org/boinc/gettrickledata.php?start=0&hostid=15811

it says "no data". Also checked my account - there are 4 finished and validated task for September:

sample_5317978_0 5317978 16 Sep 2015 | 22:36:46 UTC
sample_5313868_0 5313868 15 Sep 2015 | 22:01:44 UTC
sample_5309802_0 5309802 14 Sep 2015 | 22:13:10 UTC
ample_5305469_0 5305469 13 Sep 2015 | 20:31:42 UTC

But if I click for details:

Stderr output

<core_client_version>7.4.23</core_client_version>

for all the tasks. I have no idea whether this is the reason I cannot view the data or maybe I am doing something wrong.

any suggestions?

thanks

PS: detector is v3 (said TJM :-) ).

OK,
in fact there are several GM tube equipped Arduino projects. We also though about using Arduino Mega + GM board + some basic sensors for temperature and humidity (cost few USD) and ethernet shield to make the station standalone. It is not problem to publicly broadcast the data however this would probably need changes in Radioactive@home database - maybe to write a new connection because such devices would be outside the BOINC network.

Already talked with the devs here and it is not problem to implement radioactive@home data in other network - maybe easier solution as the project devs seem to be quite busy.

Hi,
thank you very much for your help. My colleague modified the script to write the data to text file + some improvements so it can be for example adjusted for various time intervals etc. You can get it here from his github:
https://github.com/bulanek/rad/blob/master/rad.py

hi,
we would like to test the detector in our gamma and RTG irradiator in our institute but there is no internet connection available. Is there any known way to log the data from sensor in a file or something else? Could be in terminal - linux or windows - have both.

I am currently thinking about sniffing the using HHD free serial port monitor as the sensor uses virtual COM port via usb as I know. Will try it today but maybe there is a better way.

thanks

Would be nice if the owner of the detector could test it in another location to prove or exclude detector hardware error. This is strange.

hi,
we discussed this with my colleague and according to him, those spikes take too long time to be caused by trains. Ok, I was also thinking about trains transporting something like coal with higher uranium amount but in such distance it could be not such high dose rates.

We should take in account an hardware problem in the detector. It would be nice to have also measurements from another detector near this one...

First it would be useful to know where your detector is located. For example, radon can have influence on this.

Second, I see, that your dose rate values are ranging from 350 to 500 nanoSv/h (according to graph in "Message 1823") which is slightly bigger. Is it your normal background level?

I would check the geologic map of your locality - there could be rocks with higher radioactive elements amount. Other possible source are building materials ...
