If you are interested in putting together your own CS generator, there are many options out there for sale. I did it my own way, and make it a gallon at a time in an amber glass bottle. I got 4 x gallon amber jugs from ebay for $20. These were some vintage bottles with a larger mouth opening than what is available today. You can find the modern ones for cheaper and use them. I got 10 gauge .9999 silver wire from amazon, sold by the ounce (about 21 inches), which, when it was cut in half, worked perfect for my application. I placed the silver wires about a half inch apart from each other in a rubber stopper that fit the opening of the jug; I am looking for a cork stopper to replace it though. Also from amazon I purchased an AC/DC generator, simply a wall wart that gives a maximum current of 500mA at variable voltage from 1.5V to 12V, so I can turn it down as the reaction takes off. The final piece is a pasta pot that I fill partially with water and place over the stove at low heat with the jug inside while the electrolysis takes place. The heat helps the reaction to start. In total, this can be put together for less than $100. See for yourself. Why do you think the drug companies/FDA don't want anything to do with CS? I say because it's cheap and easy to make. They don't stand to profit from it...Fuck them!
I know that was probably more info than you wanted, but if you were interested, I wanted to throw that out there. Best of luck, good sir.
