All you need is a 12v relay, a 1uf 250v polyester capacitor and 1kv diode.

Hook up the 1uf capacitor across the "Normally Closed" set of contacts. The capacitor is to help protect the contacts from excessive arc wear.

Then hook up one side of the NC contacts to one of the relay coil connectors.

To do a quick test, connect your power positive to the other relay coil connector. Connect power negative to the other side of the NC contacts.

If you wired it correctly, it will begin to buzz. If not, figure out what you did wrong and fix it.

Once it's buzzing, disconnect the power source.


Now, connect the 1kv diode to the positive power side of the relay coil. You want the diode "arrow" to point AT the positive coil connection. This means the diode's CATHODE is connected to the power positive side of the coil.

The other lead on the diode (anode) goes to one of your silver electrodes. Use a black lead for this connection since it will be a NEGATIVE pulse coming from it.

Connect a RED lead directly to the other coil connection and hook that to your other silver electrode.

If you want, put a micro-amp meter in series on either one of those leads.

Place your electrodes in some distilled water and connect the power source.

It will begin to buzz. Every time those contacts open, the relay coil's field collapses and puts out an EMF pulse through the diode circuit and through the water between the electrodes.

You can watch the amperage slowly increase as the colloid begins to collect in the distilled water.

If you grab the two electrodes, you'll feel a tingling sensation from the emf spikes since your body presents a lower electrical resistance than the water.

The spikes produce a very fine particle size.

When you see the amperage increasing, you'll know that the particle density is also increasing.

You might want to pop the relay case open every now and then and clean the contacts by dragging a strip of coarse paper between them.
