It turns out I did not have room inside for the battery pack after all, so I mounted it on top using velcro. And if so, shouldn’t it be rather 330 than 33k? Make sure to see the several readers' versions. A minimum 3 volts device is required for a good output level and it will produce a “pinging” alarm to warn in real time of any electrostatic pulse activity. Subsequent, take a gas lighter and click the device with its tip held near the antenna point of the circuit. All the interconnections ought to be as compact as possible, and the PCB ought to be carefully cleaned with thinner to be able to take away any kind of flux residue which may elsewhere produce malfunctioning of the circuit. The tiny RF detector circuit which has been in the beginning created for capturing cell phone RF waves, could possibly be as efficiently useful for the offered lightning detector design furthermore. Try reducing the value of C2 or perhaps eliminating it –or adding a resistor between it and the emitter of TR2. Mine is about 7-8% away from being turned all the way down. Now readjust VR1 back slightly to stop oscillation; use a screwdriver to touch the aerial-side of C1 several times; the alarm should sound for 1 or 2 seconds then stop.
