Prelude: Make Colloidal Silver at Home
This is the new device which I use lately, and I’m satisfied with it in all respects. It is one realization of the Selbstbau-Projekt. I have changed it a little bit. The original device operated with a 5mA electrode current. In my opinion it’s a lot. I have modified the power generator, so now the electrode current is 1,0 mA. Furthermore, I have added a polarity changer, as it is a must.
Colloidal silver generator circuit and the device
Let’s see! It is working with a higher than usual voltage, but also more efficient. Since in an idle (unloaded) position the voltage can reach 60V on the silver electrodes, we should be particularly cautious. This exceeds extra-low voltage, so it may not be marketed, and small children should not be allowed to be anywhere near!
The designer chose an unusual way in order to increase the voltage. The TR1 transformer, operating in reverse mode, transforms up the output of an alternative voltage provider 12V AC adapter. We use only one half of the 2 x 12 and 2 x 110-volt transformer. There is one bidirectional transil diode (transient suppressor) both in the primary and secondary circuits, which are responsible for keeping the peak voltage at bay. Additional voltage limiting element is the post rectification ZD51 Zener diode. This is followed by a deliberately frivolous filtering with the help of the 1N4003 diode and 22mF condenser. Thus, a pulsating DC gets to the silver electrodes, which is likely to become beneficial for the device.
The waveform measured on the silver electrodes at the beginning of colloidal silver production
The lower half of the schematic illustrates the polarity switch relay that has been actualized with the 555 timer. With the help of the applied components, it symmetrically switches polarity in about one minute.
Here is the printed circuit design created by me, to see if anyone needs it. It has been created by the Sprint-Layout 5.0 design program .lay format.
Under 1,5 hours I create 3dl, 10 ppm dense (in my opinion) quality colloidal silver with it. This density is sufficient. The more is not better! The resulting solution is colorless, tasteless. It should be like that. Okay, a slight metallic taste can be felt – eventually there is silver in it. On the electrodes and on the surface of colloidal silver the precipitation is infinitesimally low. Measurement results:
For the evaluation we need to know the following:
- I use 12 cm long; 1,63 mm diameter, 99,99% pure German silver wire electrodes, which have a subservient length of (that is immersed in distilled water) 80 mm.
- distance between the electrodes is 25 mm
I heat the distilled water during the production of colloidal silver. 220V, 50W efficient halogen-like bulb is the radiator, the same as what they use to light cupboards with. As can be seen on the pictures, above the light bulb, approximately 8 mm away there is a 5 mm thick iron plate – this is the “chock”. This piece of iron is hot when it functions, but the distilled water in the glass is around 40 °C only. It reaches this operating temperature under 45-60 minutes, the time I wait to switch on the colloidal silver producing circuit after switching on the heating earlier. Heat transfer increases significantly – the liquid temperature can be increased to 50 degrees – if I slightly lubricate the bottom of the jar with silicone grease. The heating is a quality requirement as well, because in the meantime, it can solve the thermal mixing of the solution.
