Hello
When I compare the network statistics with th station list statistics, I observce significant discrepancies between the number of signals, strokes and efficiency percentage figures displayed! Do all these webpages use the same data basics and the same time periods for the statistical data? What else could be a reason for the significant gaps? Thx for an explanation.

I have just finished building my new system blue. When I fired it up, the GPS worked but kept dropping out. Now it has stopped working at all. The only way I can get it to work is to power down for a good while and then power it up again. This enables it to work for a few minutes and then it shuts down again. Seems like a heat related problem, a dry joint maybe?
Can anyone help me to diagnose this please?
(I cant search for GPS in the forum because searching for three letter words is prohibited.)

I have just gotten the gorgeous aluminum case for my Blue circuit board.  Having installed all the parts I was very impressed with the precision of the machining and how nicely everything fits.

Then I got a couple spade connectors and some jumpers from an Arduino board to replace the shorting plug on the board to allow me to wire in the on/off switch that is on the back panel.

I cannot see how there is enough room for me to put any sort of wires from the switch to the two terminals that control power to the board.

While I cannot see a time that I might use the switch very much, and I can always unplug the power supply, I'm wondering if anyone who has purchased the enclosre has been able to gracefully wire in the on off switch?

Greetings,

On the system blue 19.3 & 8.3b2 controller signal page I see these letters
"S, L, & L P" sometimes being written just to the right of the 1A and 1B channel rows.

I have searched but have not found any information on their meaning.
What are the meanings of these letters? 

Thank you.

Hi all, for a while I have been considering how to use the Blitzorg data to do a statistical analysis for scientific research. It seems like there are complications in downloading and using the actual data, around server load, licences, data volume, cost etc. For a climatological analysis, having the raw data is not really necessary, but a summary gridded product would be excellent! I think it would also negate the worries the Blitzorg team have about allowing open access to the raw historical data.

Is it possible for you (or us - I am happy to help ) to create a gridded summary product, something like 0.25 degree resolution, 1 hour summary, in an open standard format (NetCDF: http://www.unidata.ucar.edu/software/netcdf/). For each pixel (area bin) the climate community would need to have lightning strike counts, and a measure of aggregated error regarding the detections.

Would you be open to creating such a product? It could potentially be invaluable to the climate community, and widely shared for research. I am sure that NCEP/NCAR and similar organisations would also happily host the data as they do with many others (http://www.esrl.noaa.gov/psd/data/gridded/) so that there would be no load on your servers. Potentially, you could also release the data after a first high-impact publication and garner more awareness of Blitzorg. 

Assembly instructions linked from http://en.blitzortung.org/cover_your_area.php
say to put the 2 (or maybe 3) ferrites at 90 degrees.

The picture on the same page http://en.blitzortung.org/cover_your_area.php
shows the ferrites in a 120 degree delta

What should I do?
Have I missed some documentation/description somewhere ?

thanks

The pre-wound ferrites that came with my Blue kit all have a small loose knot tied in one of the two wires.

What is the significance of this?
Should this be connected to a certain pin of the pre-amp?

thanks

Can the H-field pre-amplifier PCB be placed 'inside' the loops of a 3-loop H-field antenna?

Hey Ho Leute!

Ich bin neu dabei und wollte kurz mal "hallo!" sagen und anschließend eine Frage stellen.

Letzte Woche habe ich mein Paket mit dem Material des Blue-Systems erhalten.
Das Zusammenlöten war für mich als gelernter Elektroniker kein Problem und hat echt Spaß gemacht.
Nur der Einbau in das mitbestellte Gehäuse war etwas kniffelig, da die LEDs natürlich ordentlich in der Front sitzen sollen.

Die Aktualisierung der Firmware war kein Problem und dank der ausführlichen Anleitung hatte ich keine Problem die Station 1683 ans Netz zu bringen.

Für Interessierte:  - Ich verwende die hier im Forum oft empfohlene  "GPS-Antenne SMA 90° (abgewinkelt) Magnetfuß", bestellt über amazon. Bisher bin ich für den Preis von unter 9Euro voll zufrieden.

                            - Als USB-Netzteil verwende ich das alte Ladegerät meines Nokia-Handys ;  ich bin sehr skeptisch gegenüber den China-Billigteilen auch wenn namhafte Hersteller dort auch produzieren lassen

                            - Ich habe mir eine Loop-Antenne aus Koax-Kabel gebaut, mit 1m Durchmesser und durch die Schirm-Innenleiter-Verbindung 4 Windungen

                            - Ich überlege zusätzlich zwei Ferritantennen im 90°-Versatz mit einzubinden

                            -  An den E-Feld-Empfänger habe ich ein Stück 1,5mm² Kupferkabel angeschlossen ; <-- Wahnsinn, dass man über ein kurzes Stück Draht etwas empfangen kann

                            - die Netwerkanbindung erfolgt über  Patchkabel ---> WLAN-Repeater ---> Router ---> Internet



Abschließend hätte ich noch eine Frage an die anderen Blue-System-Nutzer;

Wie kann ich das System vernünftig erden? Gibt es auf der Platine einen vorgesehenen Punkt zum Anschluss des Erdpotentials, welchen ich ggf. herausführen kann?
Da die Platine ja lediglich ins Gehäuse eingeschoben ist, wird ja ein einfacher Anschluss ans Gehäuse unsinnig sein.
Oder reicht es am vorgesehenen Erdungspunkt der Vorverstärkerplatine die Antenne zu erden?
Derzeit habe ich einen (vermutlich) ziemlich hohen Noise-Floor von 125 mVpp.


So das war's auch erstmal.

Viele Grüße

He all, hi developers,

I'm running a Blue System with the latest Beta-SW version. This one has a feature "ALERTS"  and "ACTION" where the system calls an URL or makes some noise depending on the set parameters.

So my idea for a future SW release is if there is enough free memory left to implement a feature which brings a notification to a mobile phone or tablet if an individual limit is exceeded.
For example I'm using a home automation system based on a open source platform using a Raspberry Pi (http://www.domoticz.com/) where the developers have implemented the option to trigger those notifications.
You need a personal API-key which has to be stored in the setup and an APP on the phone like from those:


https://www.prowlapp.com/
http://www.notifymyandroid.com/
https://pushover.net/

Then depending on the settings a message will pop up on the phone if some value is exceeded even if the phone is in idle mode.
