Very true.
Msgdigger, I use a bench power supply, a multi-meter, a couple of little electronics connector blocks connected and taped to 2 bits of wood so it can stand on top of a glass beaker to suspend the silver from the anode (positive) and my very very thin copper wire for the negative (cathode). If you need help on the formulas etc, people here can help you. Once you have the bits you need and the knowledge of how to calculate things, you are good to go. See my video someone mentioned earlier to see my setup. I still use this same exact setup. The only additional thing is I made a thick copper stilt to raise the cathode out of the water so I can dip in a separate one a very tiny bit for when I am making silver citrate for use on hard surfaces. But when I make colloidal silver, it's identical to this day as what you see in the video.
