What is colloidal silver? It’s made up of silver particles suspended in water. You can search the internet and read, on one side, people who claim its a miracle cure all and on the other end, that its a scam.<\/p>\n

It’s up to you to decide if colloidal silver has any benefit, but as an engineer, developing a simple colloidal silver generator seemed like a small and interesting enough project. You could find devices that claimed to generate colloidal silver, but i was unable to find anyone sharing a schematic design. After more searching i was able to extract some key parameters that others were using for these designs.<\/p>\n

    \n
  1. \u00a0A voltage needs to be applied across 2 silver rods, suspended in distilled water. Voltages others were using ranged from 18 to 32 volts.<\/li>\n
  2. Use silver rods of a very high purity. I’ve seen people use rods made from canadian silver coins that are 99.99% pure silver.<\/li>\n
  3. Limit the current to about 2 mA<\/li>\n
  4. Reverse the voltage on the rods every once in a while to avoid having a large amount of build up on the rods.<\/li>\n<\/ol>\n

    And that’s it. The following design implements these parameters.<\/p>\n

    \"\"<\/p>\n

    The key component is the LTC6995 which generates the timing for the reversing of the polarity. The relays allow the polarity to flip. D1 is a current limiting diode, fixed at 2mA. You may have to update some resistor values to change the rate at which the polarity is switched.<\/p>\n

    You can do a test simple test for silver concentration using a Total Dissolved Solids (TDS) meter. Seems like most websites recommend a concentration of 15 -20 pmm.\u00a0 This prototype does not automatically shut off the voltage. You need to monitor it until it reached the desired concentration.<\/p>\n

    Here are pictures of the original breadboard, which does not look pretty. Then of the pcb that was fabricated.<\/p>\n

    So, does it work? Feel free to test the design and let me know.<\/p>\n","protected":false},"excerpt":{"rendered":"
