Greetings, Mike Monett inspired me to try a change in the way I brew CS. Usually I use a constant current of about 1.2 ma with 12 gauge silver wires with wetted length of about 4.5 inches spaced about 2 inches in a quart canning jar filled with Wallmart steam distilled water. I start with a voltage of about 170 and 4 hours later it ends at about 8 volts. It is stirred with a 30 rpm motor the entire time. PWT reading right after brewing is around 15 uS, and after a day or so it measures around 12. Some sludge falls off to the bottom, and both electrodes get a bit cruddy. The product is crystal clear with very low Tyndall effect.
The new way, ultra-low constant current DC, uses 0.2 ma for 24 hours (6 times longer and 6 times less current). Everything else is the same, except I used thermal stirring (7 watt night light) instead of mechanical stirring. I just finished a batch and as expected, it also reads 15 uS. But as Mike reported earlier, the electrodes stay much cleaner and no sludge fell off them. Looks like a better way to go. Power source was 24 volt AC rectified & filtered and an LM334 constant current regulator set at 0.2 ma using a 330 ohm resistor. Simple and safe (low voltage). Starting voltage to the electrodes was about 17 volts and 24 hours later it was 1.6 volts. So I am now thinking a very good CS generator can be made with a base light for thermal stirring (see my other post for a source), a 20 to 24 volt "wall-wart" AC transformer (AC adapter), a diode, an electrolytic capacitor, two resistors, and an LM334. Whole thing would cost less than $30 including shipping for the parts. Or for those liking batteries, it could be done with the base light, 3 9-volt batteries, the LM334 and one resistor. LM334s are available from electronic supply houses for less than one dollar. I get mine from Jameco (www.jameco.com). A timer to shut it off after 24 hours would be useful, but if one shuts it off anytime within 20 to 28 hours, a good brew will be produced. One power supply could power many LM334s feeding many jars if one needed to make more than a quart a day. If you try this method, please share your results with the list. --Steve Y. -- The silver-list is a moderated forum for discussion of colloidal silver.
