DAB Backyard Challeng Blog #2

DAB

Great day, my boards arrived from Element 14 today.

Did more research on the RF lightning detector and looked at some options for the flash detector.

I plan to keep both simple so that they are easy to build for others interested in duplicating my work.

 

I was hoping to make some measurements over the weekend, but in true murphy fashion, none of the thunderstorms triggered.

Just like a taxi, they are never around when you need one. 

 

I also ordered part of my surprise.

 

I will get some pictures soon, but in another expected result, the camera battery was dead.

I remember my old film camera would stay ready 24/7, so the new technology has limitations. 

 

I am encouraged that the other people in the challenge are getting their boards and their projects underway.

Looks like some good applications.

  • Hi Don,

     

    I am looking forward to following your project.

     

    Years ago, one of the first test instruments that I made was a lightening intensity meter. I took an old AM radio tuned off station and rectified the audio output that would normally go to the speaker. I then integrated the output with a small electrolytic cap and used the output to drive an mA meter. Every time there was a lightening discharge in the area the needle of the meter would jump. As the storm intensified or got closer the needle would rise higher and higher. As the storm diminished or moved away the needle would settle back to the zero point.

     

    Thanks

    John
