I’m making a new portable colloidal silver generator and so far so good. Using a 1 gang electrical box and stuffing all the electronics inside. I got a cigar box magnetic stirrer off of eBay for $50. The reason I’m making this portable generator is because it will be powered by the ubiquitous micro-USB phone charger that everyone seems to have around the house. Inside I’m boosting 5v to 30v w/ a 1k ohm resistor to run the generator at 30mA. Then I’m stepping down the voltage to 12v for the magnetic stirrer. Seems to be working nicely. The power supply must be 2A max to have enough power to power the stirrer.
