Basic and Powerful method by Steve Cox
I discovered a simple addition that makes everything else fall neatly into place for the Alternative Medicine Research Foundation's original colloidal silver generator design: Saran Wrap!
Placing Saran Wrap over the top of the container and poking it down into the water in the middle prevents over-spray from reaching the clips and has the additional benefit of limiting open air contact during the electrolytic process. With the addition of this final piece to the puzzle, I believe we have a completed colloidal silver generator design that guarantees consistent results with no undesired side-processes occurring.
A picture is worth a thousand words, as they say, so I have prepared five images, labeled with explanations and instructions as necessary. I think you'll find the overview pictures below especially useful in making all this clear to the potential builder.

| I bought two 1 oz. solid silver bars from a coin dealer. They are marked Nemo's and stamped .999 FINE SILVER. These bars cost me about $13 for both, including tax. | Here's how I bent the silver bars so they would fit on the side of the vase I use to make our colloidal silver. | Here's what the silver bar looks like when it's properly bent and placed on my colloidal silver generator. |

Using Saran Wrap to cover the top of the container prevents moisture from reaching the clips and thus becoming part of the electrolytic process. This simple addition assures you of pure colloidal silver.

Here's a complete overview of Steve Cox's variation of the Colloidal Silver Generator first developed by The Alternative Medicine Research Foundation.

Low Voltage Colloidal Silver Generator with Mechanical Stirring
These are some of the best instructions I have seen to build a colloidal silver production vessel. I found them on a long forgotten website and they have served in good stead in my quest to produce high quality low voltage direct current (LVDC) colloidal silver. The design incorporates "Ole Bob's" concept of constant stirring. Use whatever your chosen power source is to generate the CS ie: 3 - 9 volt batteries, wall wart, etc.
Materials:
Install the 2 Chassis Mount TV Coax Connectors in the lid so that the electrodes are about 1 to 1 1/4 inch apart (sort of off to one side of the top of the lid -- remember you also need room for the stirring motor).
Install the Stirring Motor in the lid ( I used hot glue gun ) so that a 2 inch or so piece of wire insulation, off of a piece of 14 gauge electrical wire, can stir freely without hitting the electrodes. It will take trial and error to determine where to place the Motor and how long to make the stirrer ( the stirrer slides conveniently right onto the shaft of the RS motor ).
You now have your version of a CS Production Vessel.
Use the Jumper leads to attach the "D" Cell battery holder with battery ( put the potentiometer in the circuit to control the speed of the stirring ) to the two connections on the stirring motor. You are now the proud owner of a working CS stirrer!!
Use more Jumper leads to attach the Power Source ( 3-9 volt batteries ) to the two electrodes. Include the 0-5 DC milliamp gauge or a multimeter into the circuit so you can read the Initial Resistance and then the final resistance when the CS is done. When you first put the Distilled Water into the vessel, the Initial Resistance should be about ½ milliamp or lower, depending on how pure your DW is. Run this setup with the stirring motor stirring the DW until the voltage is between 2.6 and 2.8 milliamps or so. It should take about 4 hours. I don't have any idea what the PPM of silver this mixture has, but it has worked wonders on many different conditions. The CS should be clear.
I am not an electrician or an engineer. I post this for informational purposes only and do not remember where it was originally posted. Use this information at your own risk!
[Four nine volt batteries can be used as well in this design. We found that utilizing the stirring device to control the current was a novel idea]
Colloidal Silver Generator II - Batteries Not Required
This AC powered colloidal silver generator II makes the ionic silver solution. AC powered generators produce colloidal silver solution with more silver particles than silver ions. So, based upon the foremost research studies, AC produced colloidal silver is supposed to be of higher quality. This unit produces a quart of the solution in 30-60 minutes depending on the voltage and amperage of the adapter.
This design is easily constructed at home for under $20, as it uses a recycled AC adapter for power. This design is simpler and more efficient than the original generator design, but not as refined as the new Colloidal Silver Generator III. The AC adapter (110V-32V/.5amp) can be easily found at garage sales, thrift shops or even in your own junk drawer. This is very economical as costly 9V batteries are not needed. This design makes a higher grade of the solution, faster, more consistently, and in larger quantities.
Historically speaking, silver has been used to treat a variety of conditions including: fungus, viral and bacterial infections and burns. It "reportedly" works by interfering with the respiration of pathogenic organisms. It is used both topically and internally; by drinking, applying to the skin, or swishing under the tongue (sublingually). Even small amounts of colloidal silver solution can kill 100% of bacteria and viruses quickly when added to samples of heavily polluted water.
Colloidal silver solution "reportedly" bolsters our immune system while dispatching single celled organisms. Because this solution is 100% lethal to pathogens, it does not create more resistant varieties like antibiotics. Applied to burns it accelerates healing and new cell growth. It can be sprayed from an atomizer on skin, or into the mouth and throat. It can also be used on infants, children and pets.
Supplies You will need to make this colloidal silver design:
AC adapter (mine was from an old HP 540C printer 30V/.5amps). This one seems ideal, but any 110AC adapter within an output range of 24V-36V/ at .5 amp to 1 amp will work.Making the Generator:
Cut wooden base to fit AC adapter, and Mason jar. Drill holes to secure adapter to baseTo increase the quality of your colloidal solution, you can use an aquarium air pump with a short hose to agitate the solution. Experts agree that this helps make the best quality solution.
The usual dosage is 1-2 tablespoons twice per day. Some people claim that their intestinal flora can be disrupted by colloidal silver. I haven't had a problem with this myself. But if this happens to you, it is best to swish it around the mouth and/or gargle the solution and not swallow. This allows absorption of beneficial silver ions through the mucus membranes (sublingual absorption). Eating yogurt several hours later will replace any friendly bacteria lost.
Many alternative health sources "claim" that colloidal silver offers some protection from air or water-born viruses and pathogens (such as the common cold, flu, smallpox, anthrax, S.A.R.S., etc.) and recommend increasing dosage to one to two ounces, twice per day when symptoms appear. These sources state that one must take the solution for 5-7 days before full protection to take effect.
*An online reader suggested that a small light bulb be added in line as a safely feature, to show when contact is being accidentally made.

Colloidal Silver DC Generator III - LW's new and improved Design
by Lightman - revised 11.16.03
As each year goes by improvements in the process of making colloidal silver abound. The Colloidal Silver Generator III reflects these improvements over the Colloidal Silver Generator II.
The improvements Include:
Making the Colloidal Silver Generator III
Supplies You will need to make this new colloidal silver design:
a DV adapter (9V/ 300mA-500mA). Available at Radio Shack for about $5. I got several for .25 cents each at a thrift shop.Additional supplies
Making the Generator
Glue two small wooden pieces to opposite ends of wooden cross bar, so bar fits snugly onto top of Mason jar. (you can turn jar upside down on top of the cross bar to glue the ends so the fit will be exact). Note: To use silver bars or coins instead of silver wire electrodes, this design must be modified. I suggest permanantly attaching the alligator clips to the side of the wooden crossbar, with the clips pointed down (1/2" below bottom of the crossbar). In this way you can attach any silver coin or bar to the alligator clips. 
The Generator III hooked up to surge protector.
Dosage
The usual dosage is 1-2 tablespoons twice per day. Some people with touchy stomachs claim that their intestinal flora can be disrupted by colloidal silver. I haven't had a problem with this myself. But if this happens to you, it is best to swish it around the mouth and/or gargle the solution and not swallow. This allows absorption of beneficial silver ions through the mucus membranes (sublingual absorption). Eating yogurt several hours later will replace any friendly bacteria lost.
Alternative health sources "claim" that colloidal silver offers some protection from air or water-born viruses and pathogens (such as the common cold, flu, smallpox, anthrax, S.A.R.S., etc.) and recommend increasing dosage to one to two ounces, twice per day when danger or symptoms appear. These sources state that one must take the solution for 5-7 days before full protection to take effect.

Additional Suggestions From Readers:
Firstly, I prefer a 1 quart glass mayonnaise jar with a plastic top, I'd be a little concerned about the metal top of the mason jar leaching into the silver water, just my opinion.
My preference for the alligator clips are the plated or stainless steel type to prevent copper from leaching into the water if splashed.
Mentioned in the article but not shown in the picture: you should add a fish tank 'bubbler' with tubing, to the system to keep mixing the solution while the added oxygen from the bubbler helps to keep the particles small. Some brewers actually ad oxygen drops to the solution to break up the silver particles, so the added oxygen brought in by the bubbler is an added bonus, not to mention the mixing action that it provides. Larger particles can not be absorbed into the blood from the lining of the stomach so it is important to keep the silver particles as small as possible. Only the smallest particles are effective against viruses and many bacteria as well.
As far as the electrodes go, I prefer using 2 Canadian Maple leaf silver $5 pieces placed about 1.25" apart. They are graded at .9999% silver and will last for ever. I buy them un-circulated and sealed in plastic by the mint, from a coin dealer in my area for about $7 or $8 ea. They have much more surface area than the silver wires so more is available to conduct electricity and drop silver particles into the solution. You can either drill holes through the top of the plastic jar-cover and clip into place from the outside (so clips don't come into contact with water). Or as I recently did - drill small holes through the tops of the coins and run .9999 silver wires through and stick through the jar cover to clip leads to. The coins will hang from the wires into the water. Using silver wire to hang off of allows the coins to be almost completely submerged (more surface area). Be sure coins are secured so they do not touch together and short your circuit causing the power supply to blow out.
When colloidal silver starts brewing in the distilled water, the water has very little conductivity and the particles break off in very small sizes (most useful to the body). As silver starts getting into the water, the water becomes much more conductive and the particles start getting larger and larger as the water becomes more conductive, until you can actually see the particles and they can become huge which are totally useless to the body, they call this silver mud (something you don't want).
You need a way to monitor this and control the current. Using the plan shown on the link, it is good to ad an amp meter or digital multi-meter that can be purchased at Wal-Mart for about $17. Just connect it in series with the positive lead of your CS generator. this can also act as a circuit breaker in case you accidentally hit the 2 leads together. When you start the brewing process your distilled water will probably read about 100u-amps (1/10 of a milliamp). You will see the numbers on the amp meter rise as micro particles of silver drops into the solution and the water becomes more conductive to electricity.
As the conductivity rises and the numbers go up on the meter, your particles will also get larger. You need to ad a current limiting device to the circuit. A potentiometer or variable resister works okay, but has to be monitored and manually adjusted to keep the current down.
You can automatically control the current by adding a 'current limiting diode'. Insert the diode in series with the positive lead of the CS generator (anode), be sure that the little stripe on the diode is pointing toward the power supply side of the circuit and not toward the electrode or alligator clip leading to the electrode.
Using the current limiting diode will allow the current to maintain at a set amount. Many people that brew their own CS, limit there current to stay under 1 ma. I've done a lot of experimenting and actually prefer keeping the current much lower, around max .28 milliamps, using a 30VDC power supply. This keeps the solution crystal clear, which tells me that the end product has extremely small particles. There is a slight metallic taste. You know the CS is there because when the solution is done, if you temporarily bypass the diode you will see the water conductivity is now about 1.2 milliamps, 10Xs greater than at the start. Results confirmed with a PWT meter (more about this later).
You can purchase various 'current limiting diodes' to keep it at 1 milliamps, .5 milliamps, or less, and experiment for yourself. When I run at a 1 milliamp limit, I find some larger particles that I end up having to filter out with an unbleached coffee filter. If not filtered these particles will probably just drop out of solution after being refrigerated for a couple of days, as they are actually not colloidal. The lower current prevents the need to filter and lessens the chance of adding contaminants or paper dust to the solution.
I had trouble finding these diodes at Radio Shack. I got the best price from Mouser.com and the service was great. I plan to build my Auto-Godzilla getting most of the parts from Mouser as well. Here is a catalog link for the current limiting diodes from mouser. Tip: odd numbers same money - a 1ma limit diode is $4.29 whereas a .91ma diode is only $1.78.

A home built CS generator works best with everything plugged into a power strip with its own built-in circuit breaker, plugged into a grounded electric timer. Most exterior type timers are grounded. The timer allows you to set it and forget it once you experiment and find out how long your brewing times should be to get the desired results.
To estimate your silver content in solution, you can find a TDS (total dissolved solvents) meter on eBay for about $10-$15, these test silver ions, not particles. Also Hanna has a good meter called a PWT meter (pure water tester), that can be purchased online for as low as $55. The PWT tests conductivity of water and may be better to test actual particle content rather than the TDS meter.
Colloidal Silver Solar Generator - LW's new sun-powered design
by Lightman - designed on 11.27.03 - Happy Thanksgiving!
Well here is another CS generator using six small recycled solar cells (I just can't stop myself :o)
The cells were salvaged from a set of old solar path lights that I got free at a garage sale. Each cell puts out about 4.2 Volts DC. So I soldered the wires together (+ to -) in series, and the little guys puts out a respectable 28-32 Volts at .4mA. 30v is the recommended voltage for making colloidal silver, as it generates minimal scale and silver crystals, and keeps the silver wires clean during the process.
The Colloidal Silver Generator IV requires several hours of direct sunlight (3-4) to produce a good batch of CS. Make sure that your cables are long enough to locate the mason jar in a dark place (inside, or in a box) while the solution is being made. Sunlight degrades colloidal silver solution. An opaque glass jar would work too.
Use a high grade of distilled water: no ionized or mineralized drinking water. Stir frequently, or use an aquarium bubbler to agitate the solution. Follow the same procedures and precautions as are detailed in the other three generator designs.
