I just checked and it's running 155mA. I'll go get a pot as suggested. Does anyone know of a way to check ppm using voltage or conductivity somehow? As it is now I have no idea what my current batch would be.
I'm not getting any cloudiness this time. I wonder if I didn't rinse the glass enough with dw the first time. ________________________________ From: Clayton Family <[email protected]> To: [email protected] Sent: Sun, October 18, 2009 3:45:27 PM Subject: Re: CS>Getting Started Sort of- it looks like your current may be on the high side, otherwise it would not be so much. It is normal- the water electrolyzes, the silver picks it up and it turns to the gunk you see. To control the amount of gunk, you can control the current more. That you can do with a resistor, diode or potentiometer in series. If you clip your wires to a multimeter set to measure milliamps, it should read zero when you start- that means there is no current flowing through the water to speak of. As the silver ions continue to go into the water, the conductivity increases and the current flow increases along with that. I forget what the details are (read formula is), but less than 1 mA current is a good idea if your silver surface area is under a certain - yours looks close to mine, and 1mA is what I am using. Just looking to see what the current is gives you some clues. I got a 75 ohm potentiometer at the surplus store and put it in series to keep a lid on the current. Maybe it was a dollar.
