1 - project box 5"x 2"x 2.5" (this size was available at radio shack but any size will do)
3 - 9 volt battery connectors with wire leads
2 - copper alligator clips
1 - toggle switch with an on/off plate or a light. (if you use a light be sure it will take up to 30 volts but it will use up batteries quicker)
3' - plastic coated wire (automotive wire works good) (12 or 14 gauge)
1' - .999 pure 18 gage fine silver wire (check the jewelry store, one that does repairs)
3 - 9 volt alkaline batteries

Tool List

Drill
Knife or wire strippers
Screwdriver
Wire cutters
Soldering iron (not a must but makes a stronger unit)
Electric tape

Assembly

Remove the cover from your box and decide how your batteries will best lay inside it, where you want the switch to be and where you want the 2 wires to come out of the box.

Drill the holes for the switch and the wires. The switch hole should be the exact size of the switch base so the switch fits tight. the wire holes should be the same size as your wires.

Cut the 3' wire into 2 equal pieces. Strip all wire ends, 1/4 to 1/2 inch, including the battery connectors. 

Lay out the 3 bat connectors so the wires all go 1 direction. You should have 6 wires in this order, red, black, red, black, red, black. Skip the first red wire, this will become your positive wire end. take the first black and the second red wire and twist the bare ends together, solder and tape. repeat this with the second black and third red wires. the third black wire becomes your negative end.

Put the switch in the hole and secure. attach the first red wire to one post on the switch. Stick the 2 pieces of wire through their holes (tying a knot on the inside prevents them from being pulled out later) attach one to the other side of your switch. Attach the other to the third black wire. Solder and tape all connections.

Now attach the alligator clips to the outside ends of your wires. Snap the batteries into the connectors arrange in the box, pad if necessary, and put the lid on the box. 

Now cut your silver wire into 2 pieces and bend to resemble Shepard staffs (helps to hook on the edge of glass). Be sure to turn off switch when not in use or batteries will drain. Expect to change batteries and silver wire about once a year depending on use.

Making your own Colloidal Silver Ingredients list

your silver generator
1/2 teaspoon of Pure Sea salt
12 ounces of distilled water (no mineral added!)
8oz drinking glass
4oz sealable jar & cover
eye dropper
8oz or larger amber glass bottle & cover
timer 
plastic spoon

Directions

Saline solution: Mix 1/2 teaspoon of sea salt with 4 oz of distilled water in your 4oz jar. mix until dissolved. It is important to use sea salt and NOT table, iodized, or any other salt. It  is also important to use pure distilled water with no additives that might react with our solution. You may use a few drops of silver colloid to preserve the saline solution for future use.

Colloidal Silver: Pour 8 oz of distilled water into your 8 oz glass. do not use plastic or metal. Add 2 drops of your saline solution and stir it with your plastic spoon.(ONLY 2 drops and NO metal) Insert your silver wires into the water and position so they don't touch. Attach alligator clips to wires (do not allow clips to touch water). Set your timer for 5 minutes and turn on your generator. A silver cloud will begin to come from one wire and hydrogen bubbles will come from the other. When the 5 minutes are up you will have 8 oz of 5ppm (parts per million) colloidal silver. Turn off your generator. Detach the alligator clips. Remove the silver wires from your colloidal silver. You will notice that the wire that emitted the silver cloud has a darker look to it than the other one. You should clean it now with a kitchen scrubby so it is ready to use next time. Light will cause the silver solution to deteriorate so store in a dark glass container. It only has a shelf life of 1 m onth (I wonder how old the stuff is that the health food store wants $20 for a small bottle?)

As a rule of thumb at 72 deg F you will get 1ppm for every minute of brewing, for every 10 deg increase in temperature it will double the rate. Do not boil the water or exceed 15 min! If black chunks appear DO NOT USE, throw away and start over. We use a double boiler to warm our distilled water to just under boiling and brew for 10-15 min to create an extremely concentrated formula.
