Hi all !
2 years ago I decided to make my own PI metal detector . For the first time I made some experiments with well known PI technology , but one day a very beautiful idea came to me - I found a way how to store and recuperate the energy that we usually waste in the resistor connected in parallel to the sensor coil . I tried this idea and found that it really works . So we can either decrease power consumption of the device or radically increase the pulse energy with the same current from the battery . And after some research I made the prototype , it shows quite a little energy consumption and some other interesting features . Now I decided to publish the circuit of this device - maybe you find it interesting ... But how can I attach the pictures ?
Best regards
Dmitry
