Since I was a young child, I was interested by thunderstorms and there lightnings.
I would be great to know, if a thunderstorm come up.
But how, to arrange this?
So I begin to studying the web for informations and facts about that material.
After many hours, i developed a mobile device.
The PotzBlitz.
But many people wrote me, that the device has a disadvantage.
I used a PIC controller.
So i start to develop a new device, based on a arduino shield.
The Blitz-o-shield was born.
How the software / system is working?
On every start the BIAS voltage of the TA7692 is increased (by PWM), as long a selectable BIAS voltage is reached.
This minimizes the spread of tolerance of all components in the analogue path.
In the normal mode the voltage on pin A0 create a average value.
If a lightning stroke, the TA7692 will let break down his working voltage.
Now the difference from the A0 pin is to high to the average value.
A counter value will be incremented.
LEDs are switch depending on thresholds.
After some time, the counter value will be decremented.
All software files and electrical schematics can be found on the following blog side:
I hope, you have fun with the experimental device
