I make a portable lightning detector,it work when it receiver a RF signal from lightning strikes,at low frequency at 300 KHZ, it make a noise (scratch) to speaker ,it show a flash led ,and show a ìÁ meter how continuity is the lightnings activity.The
original consept and design is from
www.techlib.com .
| Here it is the electronic material, plastic box ,aerial antenna,potentiometer,ìÁ meter,speaker and other electronic components
|
|
Here i have open holes to plastic box and i have place some electronics parts over there. |
|
And here the same from the other side. |
 |
|
 |
|
 |
|
| Here i make a test at one choke coil with a LC meter it is 10 mH,LC meter it show 10,58 mH.
|
|
Here it is ready the components over to PCB ,with soldering iron. . |
|
Another one photo from the other side. |

 |
|
| He i make the conection with pcb and components over to plastic box. |
|
Here it is ready . |
|
Another one photo,show the jack for external ac/dc 3 volt power |
 |
|
 |
|
 |
|
| Click here for you see a test video,how work it.
I make a test if all work good ,i touch with my finger the antenna,before i use it at real lighting strikes (Thunderstorm day) |

Added a counter meter for measurement the lightning strikes.
Here I added a counter meter strikes,from a modification at step meter counter.And i change the ìÁ meter circuit for more sensitivity.The idea it is from Chris from Nederland.
| Here it is a electronic design . |
|
Here it is A simple step meter before modification |
|
Here,you see the reed switch inside the red circle,and the magnet at side near to reed switch at left side from blue circle. |
 |
|
 |
|
 |
|
| Here i put out the pcb,and with soldering iron put out the reed switch and the magnet |
|
Here with soldering iron,i stick a twince cable for the output. |
|
Here i put the correct position the pcb again,and the small screws. |
 |
|
 |
|
 |
|
| Here i open a hole at plastic for pass the cable out side |
|
Here is the new electronic design for ìA meter,for more sensitivity.added one resistor 3,3 K,and two electrolytic capacitors 100 ìF-220 ìF. |
|
Here is ready the PCB components |
 |
|
 |
|
 |
|
| Here it ready the electronic design,i use reed relay 5 volt ,it work great and with 3 volt where i use,the type it is D1A051D00. |
|
And it is ready. |
