Interesting, gave me some nice idea - lightning coming and leaving -
This could be done if acoustical and EM radiation sensitive (count seconds
between flash and sound).
Low frequency sound, add electret.. similar to my design for the helicopter
finding missile, but now only one electret (helis are easily found by sound,
no radar needed), but that is a whole other story).


But 'one of those' NO.
First let's look at my battery consumption: 33 uA (micro ampere).
So, 33 uAh in a couple of AAA 500 mA rechargables gives 500 000 / 33 = 15151
hours of operation, or 1.77 YEARS not 100 hours as that competition.
And that is on rechargebles, and I am not even using sleep mode...
On normal batteries with sleep mode it should outlast the battery storage
lifetime several times.

And mine is PROGRAMMABLE, there is NOTHING like this is the currently known
UNIVERSE!!! ;-)

You can easily add your own ideas - algos- .
And then there is price, any self respecting amateur electronics bastler
these days has a PIC programmer, a PC with MPLAB, or some other soft to
program that PIC, the PIC costs 1$, the other parts : junk box,..
So, DIY super cheap super programmable super clever super low power super
lightning detector for a super low price.
No [it is a] great project.
Theirs is designed for outdoors???
Mine is especially designed to sit next to you while you sleep to let
you know the lightning is coming from MILES AWAY **without false alarms
to wake you up** so you can disconnect your antenna.

No mine is better :-) MUCH better....
hehe
;-)
LOL

I'mm gonna need more than a few miles so I can finish that bottle of Beam to
put my coax in! LOL ;-)

Any dust on it? (the bottle)

Never

Hmmm. Maybe the LED warning signal logic can be applied to a remote
antenna switch to provide isolation from the antenna? The the above
sensing for near by static discharges, it can hold the antenna isolated
from the last discharge plus delta minutes before re-engaging the
antenna system for normal usage. Just a thought.

Yes, but to 'isolate' you need at least a coule of meters in my experience.
A coax relay won't do ...I have seen lightning flash over electrical wiring
in a room.

So maybe explosive charges that blow piece of the coax away.... ;-)

Dunno, I just get up, go outside, just above the door is the coupling piece in
coax, turn it lose, one end of the coax throw it in the garden, the other end
the same the other way.. that is what I do.
Takes 5 minutes.

If lightning then hits the antenna it follows the coax into the ground.
