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??

Regards

Mark

Hello
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.
Cheers
Hans

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.

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?
  

Hi I need to reset my password on Blitzortung.org but cannot find how to reset/request a new password.

and gives no clue as to how to reset the password.

Hello, 

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?

Hello, 
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.

Hello, 
I am in Kenya. Do we have a way of updating my region here to Africa?

Hi,
I created a stroke alert and cannot delete it,  it will appear again after I delete the alert.
any help please? 

hello, just got my station.

==ordering==
1 x main board
2 x ferrite antennas.
+ shipping
+ paypal

total 235.84 €

==box==
content [pic]

* PCB 20.5 
** pic
** schematics[1]
** board[1]
* two ferrite antennas
* thru hole components

content arrived with no issues in carton box (10x24x17cm) with some newspaper as filling. 
pcb was inside a zip bag, the pcb sharp corners tore through the plastic bag and were exposed.

the kit didn't come with the 3mm LEDs, luckily i ordered a LED kit a while ago.
there are built in smd leds, which i failed to notice. the holes are to connect to an external led.

==soldering==
i started soldering with my chinese soldering station but i felt it didn't have enough power for handling the F/SMA connectors. 
even the ethernet grounds gave it a fight. so switched to the metcal SP-200 with a fat head. it handled the rest well. with a bit of flux for some. 

i sent my "finished" board picture to @tonuonu (who nudged me into blitzortung) and i noticed i switched the ethernet and mcu crystals. 



so i had to do a little rework. 

first blink!

==power==

Quote:"The main board is supplied with a 5V USB power adapter. The plug must be a USB-B Mini 5 pin. The power supply is not part of the kit. It must be purchased separately. The power consumption is about 450mA. Please use a 1A or bigger power supply. We have made bad experiences with 500mA power supplies."

Quote:You can use any GPS antenna operating with 3.5 Volts. The Antenna is connected via an SMA connector with the main board. The built in GPS module is very sensitive and works with antennas connected by lines of up to 10 meters.

Quote:4.1.2 Ferrite rod antennas

It is not necessary to align the two antennas to north/south and west/east. The antennas only have to be placed horizontally
