    Hi

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

    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 .

    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

    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

    Here it is the Graphic
