Hi. I am looking for help building a device like the one depicted below. I would like it to be enclosed in a case, as small as possible, and the two coils would needs to be able to be laid on the skin if needed. I would like a large area of affect. You would have to build it and ship it to me. You would have to be very familiar with electronics and small appliance repair. It is for my personal use.
