Plated-through hole reliability:
After having poor results with both ferrite and large loops (station 1808), the Magnetic sensor pre-amp was removed and examined on a bench with a few millivolts input at 10kHz.  It was discovered that the magnetic sensor preamps were functioning as attenuators rather than as amplifiers.  Further investigation showed that the plated-through holes supplying 3.3 volts to the 4531's showed no continuity.  These were then wired-through and the preamplifiers then functioned as expected. A similar (but intermittent) issue was found on one of the RJ-45 pins.  This was remedied by applying flux to the top side of the affected pin and reheating the pin.  The flux drew solder from the lower pad through the missing plating to the top connection.  Cabling and environmental performance is currently being evaluated before returning the preamps to service.  
.... Be aware there are apparently boards that may have marginal plated-through connections.

Is there an API to query if there is a lighting in your own region? You could use that info for home automation like closing blinds. I've already searched but didn't find anything.

The data feed of our lightning data often gets 404. Can the IT crew of Blitzortung please provide a stable connection to third party applications. Don't forget that this project is supported by a community of volunteers

Hi All!

Can somebody confirm if I can use the case (housing) here https://www.thingiverse.com/thing:3364124 that states it's for PCB 20.6 with my PCB 19.4?

From what I can see it seems to have the same layout, but I don't want to waste a lot of material and time on this to find out it doesn't fit...


Thanks!

We are looking for a translator into Japanese for the vector map. Please write to info@blitzortung.org. It's just a matter of a few words and sentences.

Hello,

Please forgive my lack of knowledge.  I use this website frequently to help determine where wildland fires may start in my region during fire season.  The problem I have is that, if I am not monitoring this site constantly as a storm passes, and plotting the strikes separately, then the information is lost once the strike drops off the map.  It would be of enormous help to me to be able to see strike data for a specific region aver the past 6-12, maybe even 24 hours.  Is there a way to do this?  If so, how?  If not, is it something you folks would ever consider implementing?

Either way, please know that a great many of us in the farm/ranch community are very grateful that this site exists.  Fires often don't take off and burn for several hours after a strike, and it's wonderful to have some data to help us focus our watch efforts.

Thanks!

I want to buy another clear plastic box like this one for my other station's main board. Do you have one?

This material is anti-static polycarbonate, and it was the protective shipping container for a SATA hard hard drive. It's a perfect protective enclosure for the main board; I just had to cut holes for the connectors, etc. with an X-Acto knife.

   

It doesn't have to be exactly like this; it just needs to be transparent so that I can see the LEDs on the board.

Of course, I'll pay big bucks for anything that I find usable. ;-)

I am using this tool to help deal with wildfires in our area. We are quite dry in north central Washington State, US during the summer and next to human activity lightning strikes are the most common causes of fire starts.

When I zoom deeply into the map I see a number of yellowish triangles. I can not find any information that states what they mean, could someone please let me know.

Thank you.

Hi
I am pretty sure I have been getting interference from an electric fence. It was only abut 20M away from my antennas but has now been moved further away. I have set the gains right down but now hardly ever pick up lightning. Maybe better than swamping the servers with useless signals. 
So A) can anyone identify the trace below as really being the fence and B) would direct earthing of the H field shields help. Or any other tips for that matter.
Thanks
Alan

Hello,
My detector is been out of order since feb 2018… PPS pulse problem is still on, I have try to solve that by myself and with experts, but no solutions. Any new ideas here, or do I give up and throw my system to junk…
