Q12N4401

I asked Charles Wenzel if he considered making a pocket version of his Lightning Detector. He e-mailedback and told me that he thought a loop stick antenna from an AM radio would work in place of the coils.I tried it and it worked!

Notice that . The frequency is on the low endof the AM spectrum, about 500 kHz.

The Pocket Lightning Detector has an LED lighted push on/off switch and a miniature piezo buzzer.

(SMDs drive me nuts!)

there are no coils The circuit board can be made very small.
