:)i tested that little constant curent, circuit out by runing the inputs directly to my lead acid cell rechargeble battery which is between the 1 to 40s volts needed for that circuit, the 12 volts was ok and the outputs i ran directly to my pure silver electrodes , and left it runing for a few hours and after that i used my keychain lazer power supply with lazer to test for the tyndal effect, which is the microscopic silver particle reflections when they pass through that lazer beam . you can see the particles reflect the lazer light when they pass through the lazer beam .
