  Lightning animation and map during year 2017
Posted by: RongeLuk - 2018-01-04, 21:26 - Forum: General Discussion - Replies (5)


I have made some (maybe) interesting maps and animation from Blitzortung.org data during year 2017 over Europe.

First is timelapse movie of 90 minute strikes Lightning  history with 10 minute step. 

Second is GIF animation of monthly merged lightning strikes into European map.

Enjoy  Wink

  Historical Data

Happy New Year all!!

Is it possible to select more then 2 days worth of data in the historical data?? A month at a time would be nice??

  GPS troubles with my blue box
Posted by: hazet_CHAM - 2017-12-28, 15:53 - Forum: Hardware, Software, Lightning Physics - Replies (3)

since a few hours my blue sys can't find any satellites. The blue GPS indicator on the frontside illuminates for approx. 1 sec, the pauses for approx. 2 sec. 
No PPS pulse. Antenna device is MEDIATEK. Any hints what is going wrong here? Had the same troubles already some weeks ago but they disappeared suddenly.

  Chaos Computer Club Congress meetup (34C3)
Posted by: namaste - 2017-12-26, 21:30 - Forum: General Discussion - No Replies

Hey there,

Reasonably new participant to the blitzortung project here. 
I've got two stations. one that I will be bringing to Nepal if all goes well; the other will stay hosted in Amsterdam.

From tomorrow till the beginning of the 31st of Dec, i'll be at 34C3, the yearly conference of the CCC germany that'll be in Leipzig this year.

If there's anyone that'd want to meet up there; come look for 'Justa' somewhere around the HSNL/Techinc assemblies.
I'm also bringing a fridge with home-brewed beer; so that might also be an extra incentive to come meet up.

You can also , of course, drop a private message here; i'll try to look from time to time.

Perhaps see some (other) participants or tech-heads of the project, there.

  Several questions about the circuit protection that using linear power supplies
Posted by: Jand - 2017-12-22, 04:00 - Forum: Hardware, Software, Lightning Physics - Replies (3)

This is a two-part question:

  •  Why do so many projects that I see are using basic linear transformer power supplies (i.e., mains->transformer->rectifier->regulator) but not have any kind of input protection beyond a fuse? Is a fuse really going to help prevent damage to the circuit? Are they assuming that it's going to be plugged into a surge protector, so it doesn't need to worry about excessive input voltage?
  •  If it is a good idea to include more protection in a simple power supply, is a simple crowbar-type arrangement like this appropriate?

My thought process was that I just want the fuse to open and the whole thing to become inactive if anything goes out of spec, so during an overvoltage, I basically just want to short-circuit and blow the fuse. The rule of thumb that I have heard is that your device should be able to tolerate during normal operation anywhere between 100-140 volts from a 115v nominal mains supply. This means a peak AC voltage of ~198, hence the 200v TVS diodes. The clamping voltage of common 200v TVS diodes(http://www.kynix.com/Product/Cate/109.html) seems to be in the 320-330v range, so a 300v gas discharge tube was chosen to take up the larger surges a little bit before the diodes reach their limit. Anything more than the GDT can handle would probably just arc across the component leads and trip the mains circuit breaker or blow the power supply's fuse instantaneously, right?

Is this enough? Should I also fuse the mains neutral and use a lower voltage TVS diode for D2 in order to open the circuit in the case of reversed hot and neutral? It seems like it might be over doing it to try to protect against grossly incorrect mains wiring like that. Also, now I'm starting to ask myself if it isn't even more dangerous to risk opening the neutral side of the circuit before the hot side fuse blows...

  Electric vs Magnetic antenna
Posted by: GilbertKE - 2017-12-18, 08:22 - Forum: Hardware, Software, Lightning Physics - Replies (7)


Does any one know the range (km) that Electric signal can detect? My guess is that Magnetic antenna (H) detects strikes in longer distances than Electric antenna. I see more detections (signals and  effectivity L) with ferrite antennal than E antenna.  

I am also thinking of adding a filter to Magnetic channel. Of the 3 H field channels, which would work best?

  Effectivity S & M?
Posted by: GilbertKE - 2017-12-18, 08:06 - Forum: Website, Maps and Applications - Replies (3)

What do Effectivity S and Effectivity M represent?

I know effective L represent the number of received signals used to calculate strike position with distance of up to 5000km.
