Hi guys, great thread, very informative, I'm just finishing my colloidal silver generator setup using a bench PSU.
This is my Setup:
>BK Precision 9130 Triple Output Programmable DC: this one is a little pricey but have a bunch of features, including: output timer for set and forgive operation.
>Four E's 5 Inch LED Digital Hotplate Magnetic Stirrer
>1 Liter glass beaker
>Glass encased stir bar
>6" x 1" fine silver sheets for anode/cathode
>Own created beaker cover.
I was producing ionic silver using a Silver Puppy device with polarity reversal, so this is the main reason to switch to the "old school" method.
I want to share with you my cover design just in case you may be interested on it, this one may accommodate many shapes of anodes/cathodes, including Rods, Sheets, Troys with about 1 1/2 inches of separation. Also includes a temp probe holder.
The cover may be 3d printed, I have used nylon 12.
Cheers
