Surplus Anyone? |

What a bummer! For a couple of years I was thinking about my own lighning detection and finally I found the Blitzortung system
and after hours, days or weeks trying to understand the technique and requirements my conclusion was, that this could work for me.
So let's order one, I thought. Holiday comes and it is thunderstorm season.
But yesterday I got feedback that there are no PCBs available anymore even for a longer time.
... maybe a lot of people thought it's holiday and it is thunderstorm season?! ;-)
I understand from the FAQ that Gerbers or PCB design files will not be available in public (which I can understand in
terms of reliability of data). We have a small facility for double layer proto boards with through hole vias at work.
I have a faint hope that anyone has some surplus. E.g. ordered too much; no time,
overestimates skills, prefered to buy a pony instead, ... ;-)
If that is the case and you have PCB you do not need, drop me a PN.
Apologizes for my pert question and thanks for reading. Hopefully I can give something useful back some time.

Expanding detection to nuclear events |

With grow of instability in local areas around the world and grow in technology and knowledge it slowly becomes more and more likely that non-government agents might use a nuclear device in one of the many hot spots around the world. Having an independent real-time source of information that would notify population of such events could provide huge benefits to survival of people.
Now, Blitzortung already has radio frequency monitoring stations and triangulation software with real-time output. Nuclear events produce a significant electromagnetic pulse. I am not an electrical engineer, but my guess is that such a pulse could theoretically be detectable with current Blitzortung hardware. If that is true, then it would only be a question of software changes and some kind of calibration data to add support for recognizing and displaying such information along with saving copies of raw signals for future law enforcement analysis.
I am pretty sure that this would require government cooperation to provide some information on the EM pulse profile of different nuclear events, but the public benefit might be a worthy enough cause to convince them to share the data, at least to some developers under appropriate NDAs.

Phoenix, Arizona, a hole in the coverage? |

I'm in the 85032 zip code in the US, and we are in the middle of a summer thunderstorm. It's pretty active and has lasted about 20 minutes now.
And yet, the map during this time shows (just about) nothing in Phoenix, Arizona. It is registering strikes in Canada, Mexico, Louisiana, North Dakota, ....
Earlier today, when there was no lightning here, I did see the map register strikes outside of the city about 30 miles away, and elsewhere in Arizona.
What would cause lightning strikes *not* to be mapped?

Jameco BOM / OSHPark PCB? |

Hi. I was wondering if anybody had set up a Jameco BOM for the parts for the hardware?
Also, OSHPark is happy to send you three copies of a board, AND you can make the PCB design public, so that anybody can order a (well, three) copy of the board just by visiting a URL.

precision of lighting location |

Hi
Quick but very important questions :-)
1. Some android maps use blitzortung data to show lighting position even on very big map zoom. I saw which building was hit by lighting.
How precise is lighting locating in reality?
2. At www blitzortung.org we can see growing circles at place of strike. Does the speed of circle growing reflect speed of strike sound spread?
If not, it would be great to implement it. And additionally circle would dissappear at the size where sound fades away. Of course approximately.
