Product Description:

It measures the time interval between a lightning bolt and its thunder; knowing the speed of sound, the distance from the thuderstorm is calculated.

One have to click the start button as soon as a lightning is seen and click again the same button to let the widget know that the thunder is just heard.

The calculation accounts for the temperature dependence of the sound speed: you can insert it on the back of the widget, as Celsius or Farenheit degrees or Kelvin scale; by changing the unit, the temperature already inserted is translated to the new unit.

It is possible to show the distance in the International System units or with Imperial units: also in this case, a change in the unit makes the present value to be converted.

The display color tell you if it's time to turn off and disconnect your router to keep it safe from overloading. A button let you navigate to an online help on the web.

InerziaLightning CommentaryHeads-Up - Version: 1.1, 9/26/2009 07:54PM PST

Its a not only counting, but a study of the sky to determine the front, where the hot and cold air meets. Many times people think the storm is 20 miles away, but in reality the storm is directly overhead.

St Elmo's Fire & St Elmo's Light are something to study.

If you can feel the hair on your arms or head start to stand-up or raise,
you better drop to the floor in a ball, with your feet on the ground, your hands held
against your body and try to make the smallest ball with your body.

I witnessed one day in the summer of 2007 in a food (Publix) parking lot in South Florida,
I told the lady to leave her cart right where it was and to come under the roof overhang.
She said, "I will be fine, the lightning is far away".

Well, the lightning struck her dead right there. There was about 10 to 20 seconds of time she was loading her groceries in the trunk from when I told her to take cover. There was about 8 people who witnessed the whole thing. I told them to wait under the roof overhang and they all listened to me. I held up my arm and you could see the hair stand-up. I could see other people's hair standing up at this moment.

As I started to walk out to the lot, my hair jumped right up and I knew there was going to be a strike soon.

I pleaded with the lady to take cover (she was about 28 years old I believe.).

The thunder claps sounded far, far away. I could feel the electrons in the air, it was the strongest I have ever felt in my life of living in Florida.

Props to the Program, education is needed to teach people, especially in South Florida. So many people are killed by Lightning each year.

I almost got zapped in a 28 foot boat 2 miles offshore one time, I was scared to death. The bolts sounded like they hit the boat.

InerziaLightning CommentaryDo it simply by counting - Version: 1.1, 9/26/2009 05:16PM PST

Andreas..
InerziaSoft, I think you misunderstood what "stoneage" is saying. While respecting the work you have done, the implied accuracy is rather pointless. Count the seconds between lightning and thunderclap - using your watch/clock or the sort of 'mantra' "stoneage" does (as I and probably thousands of others do) - to give the number of seconds between seeing and hearing. Divide the result to know how far away the storm is - divide by 5 for miles, by 3 for kilometres.

Usually of more importance than the actual distance is just knowing, by repeated such countings, whether the storm is getting nearer or is receding.
