Easy to build pulse induction metal detector with DSP

Although this is done in most commercial and home made metal detector circuits, it is less than ideal. The main problem is that the voltage generated by the DC/DC converter is not ripple free, and especially at the high frequencies we are working with, this may cause some unwanted coupling. We will postpone this problem to the paragraph about the power supply and will now
