Designed to dissolve sulphated plates of lead acid mites. Versions already available as products are also available. An application similar to them in this study. I would like to give the information on the long distance and give the link of the site which I easily escaped and find the shimmer, and I offer only the pcb design and boxing method that I made.
There is a critical point in the circuit. You can handle the coil of 1mH with a small winding on a small core with high permeability.
But the 220uH coil is a little problematic. The core that works in the 1mH bob is
here to bother you. The worst case is to use the nuance that the largest multi-
coil at the outlet of the ATX power supplies is wrapped around. In the meantime, it would be a good idea to measure the inductance.
