Simple Static Electricity Detector

[weather1967]

Hi

I make a simple static electricity detector ,i want to know at thunderstorm what it show

I decided to put telescopic antenna for better ,the battery i stick with warm glue

The original concept and design it is from here ,but i use another JFET tranzistor

Because I see that portable goes well to change and in the house. I decided to make another one above on my roof and with cable in the house and to connect a multimeter in place mA in line with led, and to have it doubly in the console of weather station to see the changes of the stativ electricity at storms and not only,I will epxeriment of course at sensitivity , perhaps and to change the cable antenna, I thought a round piece aluminium 30 cm diameter and 1 mm, to the present you see in foto the materials that I bought today Waterproof box, blue one ply 1,5 mm diameter for antenna, multimeter digital, PCB, the materials (transistor, led, resistance, battery 9 volt for the detector, power supply 9 volt 500 mA for the supply multimeter, because it battery will finish fast, with patent I will open hole in the multimeter and I will remove cable with nail plug, male jack for the multimeter and cable .

For today i am finnish the inside part ,and tomorrow i will finish and the conection over to my roof . <_<

Ι build another one antenna for to try the sensitivity

I take from my wife a pan from sweet 25 x 25 cm

PVC tube Φ 50

3 angle brackets 2,5 x 2,5 cm

Bolts,nuts e.t.c

[weather1967]

I build for base 2 angle brackets 12,5 x 15 cm for touch the antenna at wall over to my roof .

Incredible i do not believe it,today we have thunderstorm 80-100 km west from Athens ,and i see change at μΑ at multimeter ,i wait the range it was 10-20 km but it is very very more .I must found a way to up load the data to net ,i thought a multimeter with pc conection .

You can see the video ,you observe at 0,19 second 0,32 s and 0,55 s the up-down μA ,at the rest 3 min it is stable at 720-730 μA.

Hi again

Finnaly i buy the multimeter V&A VA18 B

http://www.amazon.com/Manual-Ranging-Digit...e/dp/B000LQONYM

Very good multimeter ,i make upload unfortunatelly with print screen software the image ,because multimeter software it not have this option to put a file the image ,and automatic i make upload with my FTP .

If you have a idea about it ?

Here i have the image

And a small video

And one photo

Ηi again all

Today we had thunderstorm at Athens

It work great

Here you can see the video with multimeter and graphic

Here it was the sat picture ,you can observe the 2 small point with thunderstorm clouds one NW at center of Athens ,and other one NE ,after little time 2 two points conection over to Athens with heavy rain and many-many thunder

Here it is the Graphic

All the concept it is here

And here the static electricity data
