  Controller 10.4 - Two Amplifiers?
Posted by: AndrewIC - 2014-06-01, 22:44 - Forum: Hardware, Software, Lightning Physics - Replies (3)

Hello,

I see from the document that Controller 10.4 has two amplifier input connectors on the board. Is it possible to run two amplifiers off the one controller, say one H and one E field?

Thanks
Andrew

Why the input signal is divided by R2 and R3 to 9% ?

  Publication Blitzortung.org maps on its website.

Hello,

I would like to put Your map http://images.blitzortung.org/Images/image_b_pl.png on my three websites. Page with the weather and a map is devoid of advertising. Can I add data from Blitzortung.org if I put information about the author?
Sample page: http://mazurskiczarter.pl/pogoda
The data are intended mainly for sailors.

Regards,

  Watching Realtime map in operation
Posted by: Dale.Reid - 2014-05-20, 02:21 - Forum: Website, Maps and Applications - Replies (2)

I think I had a somewhat unique opportunity today to watch the Beta Realtime Map software in action, due to an isolated storm and a somewhat unique vantage point.

I travelled about 100 miles from my home to attend a meeting at the Mayo Clinic in Rochester, Minnesota. The lay of the land is somewhat unique, with relatively flat prairie in all directions, only smaller rolling hills. The city is not too big, and there are almost no tall buildings except for the Mayo Clinic. From that building it is only a mile or so to farmland all around, very 'un-metropolitan' and quite rural compared to most cities with a building this tall.

I was in a 19 story building, looking westerly, with a large span of windows in a meeting room. I had my laptop watching a relatively zoomed in view of the map, showing strikes in realtime.

As the storm moved in, and lightning from the cloud to ground was visible with relatively high ceilings to the cloud, and clear visibility to the ground strike points until the rain moved in behind the strikes, I had the opportunity to see several strikes which did not show on the map, which was expected and has been discussed by the developers.

More beautiful, however, was to see a nice cloud to ground strike just to the south of a road going to the west of the building. Within a fraction of a second a second strike occurred just to the north of the road. Within three seconds both these strikes were plotted on the map, and in locations that would correspond to the north of and south of locations in comparison to the road. The plotting occurred in the same sequence as the appearance of the strikes, but I don't know if the servers calculate in any order or just as they get enough data to verify a strike. The storm approached with more intercloud lightning, much of which showed up on the map, and a few more cloud to ground, all showing on the plot map, and as far as general location from what I observed to what the map showed, being in very good agreement with observed vs. plotted positions.

Beautiful job done, developers! I can only hope to be so lucky as to have a safe window on an approaching storm again, and the system up and running to plot them. Very exciting. I hope this wasn't too lengthy of a posting, but wanted to share this opportunity to do a visual verification of approximate strike position and very rapid plotting. Dale

  iPhone app not working

Hi, the iPhone app doesn't seem to be working for me, all I get is 6 lightning strikes off the coast of Africa. This has been going on for a HuhHuhmonth or so. Any ideas how to fix this? thanks!

  LightningMaps.org: Real-time Lightning Map
Posted by: Tobi - 2014-05-09, 16:37 - Forum: Website, Maps and Applications - Replies (148)

Hi folks,

here is something new: http://www.lightningmaps.org/realtime

This map displays all strokes of the last 60 minutes in all regions. New ones are added almost in real time! The delay is up to 5 seconds. Station owners can check the signals or turn on their buzzers, wait for some lightning signal and a few seconds later there should be a new marker in the map. The best results can be seen in Central Europe due to the high station density.

Please note that this is a very first beta version! There's still some work to do. We can not guarantee for anything!

Have fun! Cool

  Wie genau ist die Blitzortung?
Posted by: sebihepp - 2014-04-22, 14:34 - Forum: Non-English - Replies (1)

Hallo,

mich würde mal interessieren, wie genau die Blitze geortet werden können? Mich würde es sehr interessieren, wo in meiner Stadt (Heidelberg) die Blitze einschlagen, wenn ein Gewitter in vollem Gange ist. Leider kann man die Karte nicht nah genug zoomen. Sind die Archive da besser? Ich überlege mir, ob ich mich nicht an dem Projekt beteilige. Ich bin Hobbyelektroniker und suche derzeit nach einem Projekt - und Blitzortung würde mich brennend interessieren. Ich habe zwar ein 40MHz-Oszilloskop, aber keinen Sprektrumsanalysator zu Hause. Und von HF habe ich leider auch keine Ahnung. Mein Bereich ist die Digitaltechnik mit µControllern, CPLDs und FPGAs. Gibt es zu den Antennen und Verstärkern gute Anleitungen?

Viele Grüße
Sebihepp

  Kit Construction
Posted by: N1LF - 2014-04-16, 05:34 - Forum: Hardware, Software, Lightning Physics - Replies (6)

I've been actively experimenting with sferics receiver, and TOA lighting detectors for several years. Very interested in adding a detector at my home in Central Alabama (near Birmingham) in the Southeastern US.

Unfortunately, time has robbed me of my eyesight for close-up work, and made my hands too unsteady for SMT type soldering. I'm looking for another forum member who would be willing to assemble the kit on my behalf. Happy to have complete kit shipped directly to your location. I can also pay you for your time and labor via PayPal, or money order.

If you're interested please contact me by PM or offline. I'm grateful for any assistance.
