    Uuh, for normal people the topic of this thread sounds like “Alien vs Predator”.
    Sorry.

    Very nice work Hexide!

    Really like your map with included client-site (highcharts) charts!
    I was very busy at my day-job the last weeks. Tell us if you need help, ideas or … chocolate.

    Improve of this new index is significant!
    It should also improve your creation of the current charts.

    But don’t use too much indices, cause they will lower your insert-perfomance.
    … but at the moment (you have a maximum of 160 inserts per minute) this will not have influence. 🙂

    that’s it; what I wanted to say:
    You must not use mysqldump for big production databases.

    One way would be, to master-slave replicate the DB and dump the copy:
    https://dev.mysql.com/doc/refman/5.0/en/replication-howto.html

    Other way, the one I’d investigate in, would be XtraBackup.

    Btw. Radu, could you install vim, screen and htop on the dev-server? This would enlighten my commandline-feeling.

    Thanks Radu for the current firmware.
    It works fine and also fixes the JSON issues described here.

    For all interested in this, JSON now looks like this:
    {"data":{ "id":"11000035""type":"1","detector":"SBM-20","cpm":20,"temperature":4.69,"uptime": 19544}}

    You could use it for your own analysis or 3rd-party processing.
    See the nice work, Pixel K did:

    @Halon: do you have a Cacti up and running?

    Edit:
    Reason why I’m asking this: Last weekend I installed Cacti on a test machine. It’s about 1.5 h including some first steps. I think it works fine, but it’s quite old-school, like webalizer.

    Is it worth working with it? If you only use it for one graph, you could faster code a realy nice graph yourselves.

    And there are interesting alternatives like Zabbix and Munin.

    So, why Cacti?

    Hi Halon,
    there is the possibility to access a JSON output in the current firmware. This is accessed directly from the device. So you could automatically access the values in whatever interval you want.

    What kind of interface would you need/prefer for cacti?

    New firmware, see: https://www.uradmonitor.com/topic/the-new-firmware/

    P.S: Sorry, I moved your interesting entry, because client-charts refers to web browser charts at the moment. Hope that’s ok.

    hi Radu,

    Valid HTML
    That’s OK, I see the problem with controllers memory.
    We have to see, if there are issues with browsers.
    I don’t need this server, but there is a benefit for local use or local (third party) data processing.

    Maybe you should only return that JSON (with word-wrap \n), it is quite readable. A nice HTML5 version could be a HW-update with more EEPROM.

    JSON
    It looks like this at the moment.
    Þ¿ýòü|ó¿s¿ßó;÷¬ö }‘° ß¿V{ï{ŽÿÝõ«þ‰~Ë~‘í Gó$c­Ÿ½—Ýÿ ;úÝ—ß ne¿ û ß+ÖÓÿžóÄf­Ûã^û çùú±ýÀ"type":"1","detector":"SBM-20","cpm":20,"temperature":10.81,"uptime": 186086}}

    I used current Firefoxes on Win7, OS-X and Linux. I checked others, all the same.
    But have a look at lynx, attached. 😉

    Do you have code included in EEPROM? I don’t think so.
    What should I see in these cryptic parts? Think this is quite short, maybe it’s only “{{“.

    Server IP
    See attachment, too.

    I just set up the current firmware, Radu sent me.
    It works fine and fixes the minor DHCP error we described.

    • Programmer: AVR Dragon (USB)
    • Software: Atmel Studio 6.2 -> Tools -> Device Programming
    • I made a simple converter from 6-pin ISP to 10-pin ISP.
      The 10-pin header has to be connected rotated as @Radu describes.
    • The AVR Dragon does not supply the 3.3V power. You have to power the device itself. Dragons level shifters get powered from the urad-device.

    It is very dangerous to open any electric device, especially this one.
    Do only what you, yourself understand and can absolutely take all the responsibility.

    @Andromedan and others

    Radu just sent me a new version of the firmware.
    This version fixes the DHCP problem described here.
    I see an all-green capture now. 🙂

    Hi Richard,

    That’s fantastic. 🙂 Did you already engage in this?

    How long (time) is the “impact” on earth? I read about 0.3 to 30secs for the GRB.
    And how strong is the radiation increase in % over normal?
    I’d like to estimate the response for a single URAD device in the 1-minute samples.
    Example: Impact is 0.5 counts (CPM) more than it would be.

    Currently I’d assume it’s too short and too weak to find it with dosimeters on earth. 🙂 (But don’t know!)

    Next would be finding correlations over several devices.

    Peter thats cool, I like the Shift-drag ant the included average (read line below chart). I have to check this.

    Oh, “highstock” does everything I was dreaming of. Including a nice overview below the chart, fixed and manual ranges and zoom.

    Think https://www.dokuwiki.org is good too, and not so bloated. But MediaWiki is good and most people know it.

    I definitive think a Wiki would be good. There is no need for millions of articles, but some static articles (that could be extended) are useful.

    You could quickly open a FAQ list. And insert articles like Radus detailed and good explanation on Calc Dose from CPM.
    Also you could link to the wiki from questions in the forum. It’s for static information and the blog and forums link to it.

    so, did it: https://www.uradmonitor.com/topic/how-to-detect-and-act-on-an-incident/

    Think peoples tests will normaly not be longer than 6h (-> single sensor alarm).

    And messages should not be nervous and excited, but rather technical.
