Parts are in. Will send PCB to production tonight. Should be available in a week or two.
Working on the driver now.
Couple of questions:
-Not sure if I have to add more lables for the socket. It should work with SoftwareI2C too.
-I am exposing only 6 (used) pins on the top IDC (for non-Gadgeteer folks). Would that be ok or should I put all 10?
-Let me know if anybody interested in this module.
What does it do?
Ooops, 
It is lightning detector up to 40km away
Ah, very nice.
I never knew I needed one until now. I would like one.
@ Architect - cool, so whats the theory of operation?
I’m up for one, but thunderstorm season is pretty much over up here.
@ Mike - number one on the list!
@ ransomhall - number two 
Yeah season is over, but I will have lightning emulator to test the module with. (Working on it)
Me either. Very cool! Definitely sign me up for one.
@ ianlee74 - #3
@ Justin - It is based on the dedicated Franklin Lightning Sensor IC (AS3935)
Key features:
[ul]
Lightning Detector warns of lightning storm activity within a radius of 40km
Distance estimation to the head of the storm down to 1km in 14 steps
Detects both cloud-to-ground and intra-cloud (cloud-to-cloud) flashes
Embedded man-made disturber rejection algorithm
Programmable detection levels enable threshold setting for optimal controls
SPI and I²C interface is used for control and register reading
Antenna Tuning to compensate variations of the external components
Supply voltage range 2.4V to 5.5V
Power-down, listening, and active mode[/ul]
That looks pretty neat
Not much use here - now if you had a gray sky drizzle sensor… 
A lightning emulator? Now that sounds interesting. A Tesla coil or Van der Graaf generator perhaps? You gotta make a video if it’s anything that makes visible sparks
@ Justin - Lightning produces very distinct noises at roughly 40-60 Hz that can be heard from a very simple radio from a long distance. The trouble is there is a lot of man made noise at that freq, primarily power line hum. From what I can gather these guys have figured out a way to get around removing that interference. Google ‘natural VLF radio noise’ for tons of info.
Jacob ladder?
@ ransomhall - flicking the light switch on and off really fast - i’ll send my kids over
Didn’t think about it, but it would be interesting to see how the module will react to it.
Taser
Sweet. I want one, not sure why but I do!
@ Gus - You are already on the list at #0
@ Gus - No, we want one
We should have it on top of GHI building and then tweet when we detect lightning
