I made some with regulated DC voltage for comparison. The four new ones are in the front color matched to the earlier tests.
Only an occasional 50uS off time to measure the galvanic voltage. One thing (perhaps the only thing) current pulsing IS good for!
They are all 0.2 liter with 2 inch 12ga. wire electrodes spaced 2.25 inches apart. The cathode is fully inserted like the anode. The usual 1mMol/L of Na2CO3 and put in 1mMol/l Glucose after the runs.
They are all 20ppm with 3.6 Coulomb used for 0.2 liters.
The first one on the front left is 20.0VDC. The current was 14.37mADC and the galvanic voltage was 2.3V. This made lots of precipitation at the cathode. But like kephre says it actually does just dissolve into the solution with a little time. At the end of a run at this level it might be a good idea to stir it a little while until all this is dissolved before adding the Karo. I wonder if the precipitate could be made in a powdered form to make colloidal silver just by adding a powder to distilled water. Sort of like powdered Gatoraid? Probably not very shelf stable especially if it had to be mixed with NaCO3 and Glucose powder*.
The second sample from the left is 10.0VDC at 6.73mA. The galvanic voltage is 2.04V fairly clear and this turned out only slightly darker than the normal 5mA stuff. Looked perfectly good and normal really.
The third sample is 5V at 2.74mA. The galvanic voltage started to drop a little to 1.92V and it shows a little low voltage trouble but not noticeable unless compared to the others.
The last sample is at 2.5V, 1.60mA with a galvanic voltage of only 0.64 volts. This has the full orange milky look to it caused by low voltage.
So the results actually turned out just as expected. So after two months I am starting to get a little good at this stuff
I should have just bought a SilverTron......
But I know a whole lot more by designing and building my own car and understanding exactly how it works rather that just going over to Ford and buying another Mustang.
We want silver salts, mainly silver oxide to be IN SOLUTION. What you see as smoke is the same silver salts precipitated out because they exceeded the solubility limit in the diffusion layer. How long it takes those particles to redissolve depends on how big the crystals have grown in the diffusion layer.
Yes! I made a bunch and sat there are watched it dissolve! I guess it is good stuff after all. And I bet no matter if you see it or not the net amount is pretty much exactly the same no matter what "good" process is used.
But I am thinking if one uses high currents for faster production one should wait after a run until all the precipitates are fully stirred and dissolved in before adding the reducer.

Nobody on this forum, I repeat nobody, has used, made, experimented with, or made colloidal silver with as many different commercial machines than me.
I can categorically state that the SilverTron is...
The SilverTron is a cool uC controlled current source and Coulomb counter... Any kid can make the first one and any EE can make the second.
But what really makes the SilverTron THE
magic machine is the pure genius Bill has put into it this whole sport! His great knowledge of chemistry and electronics came together to just solve this whole world!
ii) the ONLY way to make colloidal silver to an accurate ppm for injection without electrolyte. ... However, it does mean that the product can be made very slowly with great accuracy.
Micro and nano amps
While still keeping the voltage high
-- Oh... I guess if the resistance is 250000 Ohms keeping the voltage high is pretty easy!
I have not believed anything in the colloidal silver world unless I can prove it for myself. Of course, I have no knowledge in most of this so the learning was hard and I messed up many times. However, I have never been able to disprove or fault Bill on anything! If he was BSing us, I would have found it by now.
Most colloidal silver guru's get ignored after watching their youtube videos for 15 seconds........
But Bills genius and thought behind all this really had made this a fascinating and great journey for me!
*The pharmaceutical folks have a ton of ways to fix that... Colloidal silver "timed release".... Ambien - $3 AmbienCR - $105!!!! Those F....... Must stop commenting now...
