I use a bench power supply, and a timer/relay switch I got from Graingers to do the polarity switching with a 7805 and a 50 ohm resister for the constant current source.

Hi Marshal,
Have you any circuit for that or an other generator SC ?

I built one that produces 2 gallons an hour continually, a 55 gallon drum a day. I use an inexpensive 2 gallon aquarium kit for the reactor with 3 6X8 silver plates in it. The pump circulates the water, and I use 100 mA of current using a current controller, switched by polarity every minute. and a pump with a flow meter to run water through it continually at the proper rate. It produces 15 to 20 ppm crystal clear CS.

    I'm new user in the colloidal silver.
    If anyone has any plans to build a device that is very good
    production could give me one? I built one but I think it not works
    well, gives me a black electrode and another silver electrode and
    floating gray, a thin layer of shiny silver.
    Thanks
