you have a colloidal generator instruction how do i access it
Have you tried the search box in the upper right corner? If it's here, that should find it.
I am guessing you want to build a device to produce a colloidal suspension of small particles of silver metal in water. The reason I have to guess is because the word colloidal is very general. A colloid is a mixture, specifically a "substance microscopically dispersed evenly throughout another substance". More here:http://en.wikipedia.org/wiki/Colloid But the reason I'm guessing a colloid of silver metal in water, is because that's something I've read about before. Supposedly if you do too much of it, it will turn your skin blue. A few years back there was somebody in Montana running for public office with this condition, called Argyria. His critics called him unkind names, like "Smurf", and "Ol' Blue".http://en.wikipedia.org/wiki/Argyria Anyway, presuming you're duly cognizant of the social stigma of smurfiness, and possibly other dangers involved, the usual recipe for making colloidal silver in water is an electrolysis setup, with both the anode and cathode made of silver metal, and an electrolyte of almost pure water. Probably the cheapest, and purest, silver you could find for the electrodes would be in the form of silver wire, sold for jewelry or chemistry purposes. I think silver coins, including those from the former U.S., are usually alloyed with copper. I think copper in ionic form is usually poisonous. E.g. copper(2) sulfate is poisonous. So is copper(1)chloride, and copper(2)chloride. So I'd avoid using silver coins. The reason the water is "almost pure" is that pure water will not conduct electricity. If I remember correctly the usual recipe says to start with pure distilled water, then add a "pinch" of table salt (mostly NaCl), however much a pinch is. Guessing that the amount of water somewhere between 100 mL and 1 L. In fact I recall seeing web pages for retail-mongers selling such things. You can be pretty sure that whatever device they're selling, that they do not provide the silver, the water, and the pinch of salt. In fact you could probably learn a lot by finding the web-page of one or more of these retailers, not for the purpose of buying anything from them, but just to glean what you can from their documentation, instructions, pictures, etc. You can puzzle a lot out this way.http://www.google.com/#hl=en&sugexp=ldymls&xhr=t&q=colloidal+silver+generator+sale Anyway, the thing, the device they're selling is something purely electrical. It is, in fact, a power supply. Maybe it supplies constant voltage? Maybe constant current? Funky ultrafast pulses? Who knows? For a nice electrolysis setup I'd want a constant current regulator. If you want something cheap and easy to try, I'd suggest a 6V lantern battery, or maybe the 5V bus from an old computer power supply. For an approach like this, there is no current regulation. The current that flows will depend on the resistance offered by the cell, i.e. your glass of water with the silver wires in it. You can adjust the current somewhat by changing the distance between the electrodes. BTW, electrolysis is in many ways like Forrest Gump's proverbial box of chocolates. You never know what you're gonna get. Well sort of. You won't get out some element you did not put in. That's the reasoning involved in using pure silver for both electrodes, and almost-pure water for the electrolyte. In chemistry books, the operation of electrolytic cells is usually described in terms of ions. There is such a thing as a silver ion, e.g. Ag+, Ag+2, and a silver ion is not the same thing as a nanoscopic particle of pure silver. How it is that a electrolyic cell actually produces colloidal silver is something I don't understand, and I'm not sure how you're supposed to confirm that your device is actually working. I guess you just check the silver electrodes for signs of erosion, and if they are eroded, you just assume that the silver must have gone into silver nanoparticles. Anyway, that's all I've got for you, and remember what I said about smurfiness. As they say in the beer commercials: Please drink responsibly. ;-)
I use a single drop of lemon juice. The resistance spikes down and then recovers in five minutes when the citric acid has formed silver citrate, but the silver ions have already been formed, allowing electrolysis to continue.
OK. Thanks for the tip.
This looks like a good one:http://www.berzerker.net/jonboon/free/survival/Plan%208%20CS%20Generator.pdf
This diagram takes 110 AC and reduces it to 24 AC, then rectifies it and runs it through a 5 volt regulator. When the resistance is high, five volts is all you get. When it gets up to 20 mA, it holds that amperage.The voltage regulator could be 12 Volts to force 12 volts into the water at the beginning. The amperage recommended is 1 mA for the smallest particle size. The evidence of operation is the bubbles on one rod and tarnish on the other. No LED in series before the electrodes would be able to respond to that amperage and light up.
Erm... 1 mA is "recommended" by whom? I mean, a reference or a link would be neat if you've got one. BTW, if you want to limit your circuit to an output current of just one 1 mA, then change the 270 ohm resistor to a 5000 ohm, or 5K, resistor. That is to say: (5 volts)/(5000 ohm) = 1 mA. Whereas before it was (5 volts)/(270 ohm) = 18.5 mA

Thanks for the reply, and thanks for the link. I like this one. I mean there's a lot of amateurish stuff out there on this topic, but this guy looks like he knows what he's doing, or at least he knows how to measure voltage and current, and how to build a constant current regulator. I'm guessing that he's starting each run with pure water. I mean I did not find anywhere where he says/writes the words "I start each run with pure water", but there's a part where he's obsessing about the difference in initial resistance between the 1mA test run and the 2mA test run, and saying that he thinks this is due to insufficiently cleaning the glassware between these two tests. Anyway, I'm guessing that initial resistance is resistance offered by pure, or almost pure, water. Thanks again for the link. This is helpful, and I think this colloidal silver making stuff is starting to come into focus for me.
