CSPolarity swapper circuit
I have built an experimental polarity swapper circuit, for another member of the list to test. My goal is to find out what swap frequency produces CS with reduced electrode waste and tarnish, without increasing production time to more than double the the DC production time. The experimental circuit has a selector for these numbers of seconds per swap cycle: 4, 16, 64, 256, 1024 I'm hoping this range of choices will demonstrate a transition from AC to effectively DC operation. It also allows for either two phases per cycle (half the time outputting each polarity) or 4 phases per cycle (1/4 of the cycle with one polarity, 1/4 of the cycle idle, 1/4 of the cycle other polarity, 1/4 of the cycle idle), just to find out if this option has any measurable effect except to lengthen the production time. The circuit runs on any DC supply between 5 and 15 volts and includes 2k ohms of resistance in series with the output. Is there some way to post photos and other data files (schematics and simulation files) about this project, directly, or must I find some place to put them on the web and link to them? I want to make this simple design available to anyone who is interested in building a unit. If the test process demonstrates an optimal cycle time, the selector switch (the most expensive component) could be eliminated, with the optimal choice hardwired. -- Regards, John Popelish -- The Silver List is a moderated forum for discussing Colloidal Silver.

You'll need to do the latter. There's a rather strict message size limit on the list which precludes all but the tiniest of attachments. I want to make this simple design available to anyone who is interested in building a unit. Sounds nice. Would also be a good project to do using one of the smaller Arduino variants, and allow you to vary things at will. Hardware could be finalized when/if an optimal design emerged.

Re: CSPolarity swapper circuit
Hi John Looking to volunteer I may have access to an ardiuno guy who may be able to program the chip with supplied code. The rest of it I can manage in my spare time As an experiment I was looking to use my beck blood zapper to brew the CS with a current limiting diode..

I suspected as much, and also understand how it protects the list users from malicious attachments. The simulator file for LTspice is a text file, and is quite compact, so maybe I'll get one of those working, in case someone wants to play with the simulator.

Would also be a good project to do using one of the smaller Arduino variants, and allow you to vary things at will. Hardware could be finalized when/if an optimal design emerged. An Arduino could certainly handle all the timing requirements, but has to have a rather accurate, low voltage supply, while the electrolytic process might benefit from a more flexible supply voltage. The nice bit about the simple circuit I made is that it is happy with a 5 to 15 volt (and possibly 18 volt) supply. But a flexible output driver could easily be designed for an Arduino. -- Regards, John Popelish -- The Silver List is a moderated forum for discussing Colloidal Silver.

The rest of it I can manage in my spare time As an experiment I was looking to use my beck blood zapper to brew the CS with a current limiting diode.. The only thing this circuit does, is to time a cycle of alternating output polarity. Is the Beck zapper unidirectional? If so, it it probably easier to rebuild the entire thing, to have a bidirectional output, than it is to try to add the bipolar output to the Beck. My output is just a pair of D flip flops (CD4013BE) hooked up to a settable clock, as a two bit shift register (first Q output to second D input), with the second Q bar output fed back to the first D input. This forces the two flip flops to generate the following sequence (first bit is first Q, second bit is second Q) 00 10 11 01 The two phase mode just uses the Q and Q bar outputs from one of the flip flops (doesn't matter which). The 4 phase mode (with the idle time between each of the active polarities) uses the Q output from each flipflop (or equivalently, the Q bar outputs from each) Since CMOS gates and flip flops have a fairly symmetrical output driver, they can sink or source current. For the two phase output, one output is sourcing, while the other is sinking, and they take turns. The 4 phase output sources from one flip flop while sinking at the other, as long as the two flip flops are in different states. But when both Qs are high or both low, there is no voltage difference between them, and the drive goes to zero. Of course, all this timing could be done by an Arduino, using two digital outputs as the drive signals, with CMOS buffers, like CD4049BE or CD4050BE added after, to produce the cell drive current. I think precise current control is a lot less important for reversing polarity drive than it is for continuous DC drive, because the silver does not just pile up at the cathode, but sloshes back and forth. As I said in the update, I just added a 1k resistor in series with each output, but you could get a lot fancier and add a current regulator, if that was useful. A simple two transistor or jfet current regulator, inside a bridge rectifier, and in series with either output, would make it act like a bidirectional current regulator. But the diodes and regulator use up a few useful volts, even at high cell resistance. -- Regards, John Popelish -- The Silver List is a moderated forum for discussing Colloidal Silver.
