Hi, The current should be ok For even a medium sized wire but the brew time will be slow depending on the quantity required. I think a water pump is overkill. To be honest at such a low current and slow brew I do not think you even need much agitation at all if any! The Bruce stenulson design had very little adequate current limitation and is harder to measure progress as you would need to measure the current of a dc offset 25khz frequency which most home or hobbyist meter will not do. I have tried this design and find it unnecessary. A lm317t or proper proper current controller ic will be adequate you will not need polarity swapping.
The lm317 is awful to use at low currents as a current controller. Below 1 ma it's not recommended. I would use a lm334 with two resisters and a diode you could do this easy. Also it goes up to 40vdc I use a dc-dc converter to get my 30v. That allows me to use low dc mains power such as a mobile phone charger or USB port. I do agree with Bruce stenulson in that the cathode need not be silver since there is no precipitation from the cathode and it adds no value to the process so far as I can tell. I have used a stainless steel cheap tray as a cathode successfully. Be very mindful of the polarity if you do this! Is suppose having both electrodes silver is more foolproof. I found that having good double distilled water is amongst the most important part of the process. And genuine and clean silver And good clean brewing vessel. I hope you found this helpful. With peace. Regards Asif. On 29 Sep 2011, at 00:57, "[email protected]" <[email protected]> wrote: > This my first post and I am gonna be building my generator very soon.
