  Time between strikes
Posted by: Jon1980 - 2014-08-19, 22:39 - Forum: Website, Maps and Applications - Replies (4)

Is there a color chart somewhere that shows the time line of a strike? I see that they change color and am not seeing anything to show me how long it has been since the strike happened. Certain customers shut us down due to lightning and we have to wait 30 min from the last strike within eye sight. I found this and would like to use it more often but i need to be able to prove that we are in the clear. Any help would be appreciated.

  Ferrite Rod Antenna Shielding
Posted by: Dave.Auld - 2014-08-18, 08:20 - Forum: Hardware, Software, Lightning Physics - Replies (4)

Morning All,

I have completed building the amp and controller and they are working great, just need to build the antenna.

I have the 200mm ferrite rods supplied by Blitzortung and was looking at the various instructions and guides etc. but I'm a little bit confused and hopefully someone with so more knowledge can help this noob.

In the guides it says to try without the shielding first to save some effort, and then also recommends to use ribbon cable to shield PVC conduit if required.

Why not use copper pipe instead on pvc conduit wrapped in ribbon cable, to me that would be the ultimate shield or is it a case of that it would be too thick or is there something else I'm missing?

Alternatively I was planning on using the pvc conduit wrapped in adhesive aluminum foil .

Please can you point me in the right direction before I head off to the local DIY store to pickup the bits I don't have. (I'm fortunate to have outdoor shielded cat5 and shielded rj45 connectors left over from my CCTV install).

Thanks,
Dave

  Interested in setting up a station in northern Norway
Posted by: Drayton - 2014-08-16, 12:25 - Forum: General Discussion - Replies (5)

Hi

I've been following Blitzortung for a while now and have noticed that coverage in northern Norway is quite poor.

We've had several thunderstorms up here the last few weeks and as soon as they go north of Helgeland most of them go unnoticed by Blitzortung.

I live in a rural area where interference should be pretty low, and I'm interested in setting up a station here whenever there are PCB's available again.
My coordinates are roughly 67 16'23.62"N 15 7'0.65"E

I have both the skills and all the required equipment for assembling the detection hardware.

Thank you

  Dokumentation und Materiallisten
Posted by: oliverr - 2014-08-16, 07:20 - Forum: Non-English - Replies (5)

Hallo Forum,

ich vermisste hier auf Blitzortung.org die Dokumentation des Systems und der Platinen und deren Stücklisten für die Materialbestellung. (Und wenn sie doch da sind, finde ich sie nicht.)

Ich habe nämlich die Platinen von Egon bekommen und suche gerade die Stücklisten. Dadurch das ich sie hier nicht gefunden habe, habe ich mal G.... benutzt und da auch was gefunden, aber es würde schon besser hier auf Blitzortung passen und nicht im Internet verteilt sein.

Wäre super entweder einen Bereich direkt auf Blitzortung.org machen oder hier im Forum.

Danke und Grüße,
Oliver

  Earthquake detection network
Posted by: baudeagle - 2014-08-14, 05:46 - Forum: General Discussion - Replies (3)

New here - Hope this is the correct place to post this idea.

I am impressed with the lightning detection network that your group has developed. From what I briefly read and understand, the lightning is triangulated by using a time on arrival to sensors at known locations. Taking this application a bit further, could a similar type of system/network be utilized as a earthquake detection/alert system?

I saw this story on NPR about earthquake detection /early warning systems (1) and now California is going to start spending some money to have these installed (2). This got me to thinking about this lightning detection network that you have collectively set up. Would it be possible to set up something similar like this (3) or (4) using your backbone of lightning detection (but forked independently) as the basis for a early warning system? Maybe this could be open-sourced and or crowd-sourced and receive some of the funding from (2). Homemade earthquake detectors appear to be reasonable in price and affordable to build (5) or (6). These could then work together in a similar manner as for lightning detection sending out text message alerts/warnings (7) when a certain number of stations detect seismic P-waves.

From what I understand, a couple of seconds of advanced warning before an earthquake hits will save a lot of lives.

  Betriebssystem
Posted by: Bonzo - 2014-08-13, 19:34 - Forum: Non-English - Replies (2)

Hallo,

ich habe jetzt viel gelesen, bin mir aber in einem Punkt noch unsicher, weil ich in der
FAQ was über eine 'serielle Verbindung' gelesen habe... Daraus ergeben sich doch
noch einige Fragen:

Gehe ich recht in der Annahme, dass das mit der seriellen Verbindung noch das alte
System betrifft und dass das System "Red" vollkommen autark arbeitet, also keinen
heimischen Computer erfordert sondern die Antennen und das GPS System direkt mit
dem WAN (über den heimischen Router) verbindet? Den "Tracker" benötige ich also
für "Red" nicht? So verstehe ich "Rechnerloser Betrieb".

Dann habe ich was von Rückkanal gelesen, der den Antennenverstärker steuert (Gain Control).
Ist es denn entsprechend nötig hierfuer einen Port am heimischen Router zu öffnen?

Kann ich weiterhin davon ausgehen, dass man das System aufbauen, programmieren, betreiben
und warten kann ohne einen Windows PC zu nutzen? Ich habe nämlich keinen solchen und nutze
ausschliesslich Linux (Debian & Flavours)

Ist das Flashen der Firmware mittlerweile über ein Webinterface möglich?


Netten Gruss

  Contribution for central/southern Europe part
Posted by: blueone - 2014-08-13, 18:35 - Forum: General Discussion - No Replies

Hello,

I am one of the fresh enthusiasts following http://www.lightningmaps.org/realtime?lang=en and http://www.blitzortung.org for few months now. I read crucial infromation on this project, read the official document, whole 95 pages Smile...
I have computer skills, but electronics and soldering is not my cup of tea, glass of beer, ....

I noticed there is a hold on HW distribution. When available, I would like to buy one set, already assembled that is and set up one additional input point somewhere around this coordinates: 45°59.7"N 14°36'"E.

Best regards
Matt N.

I hooked up a WB ferrite antenna to the scope and could see a couple of strong signals around 300KHz in the FFT view.I believe them to be DGNSS Gothenburg and Færder (DGPS stations). I assume these will be well taken care of by the LPF in the amplifiers?
