When there is a straight switch from pos over to neg there is an uncomfortable spike.

Ideally you would want the switching to fade from one polarity over to the other, eliminating the spike.

Nice healing device
Dont know if replacing the mat with ferrite ring magnets will have the same effect
I usually put magnets inside the pillows and placed it on the joints and terrible headache which easily deminish especially if the magnet is cool to touch.....
Using the rotor magnets in distilled water improves the taste and lessen my craving for COKE   lol

What problems do you experience with your joints... arthritic? would like to know more on how you use the magnets. Is the healing principles related to general magnetic therapy as in magnetic wrist straps? My Wife has arthritus in her joints quite badly, I've heard from one person who gained benefit from using the switched polarised mats based on Lee Crocks device. Regards

@ Bob Smith, have a look at this previous posting:

This circuit uses a 555 timer and 12 volt supply with relay output, so you will have to alter the circuit for a 3 volt switched output without the relay. See what you think... hope this helps. Kind Regards.

Ineresting comment, the relay contacts are not switching any measurable electrical current as such other than presenting a persieved + and - field at the mat so the theory states!
