got it work with a fresh battery and new different wiring. Made a test run on my lid... This is going to be fun. Kettle is up next.

Electricity is a lazy creature. It takes the path of least resistance. It u become that path, ot will hit u. MaxOut, sir, a car battery has the "potential" to kill u. Thats all electricity is anyway is "potential energy". Given the right condition your heart can be stopped@ .75mA. Now, it is unlikely and using a battery charger u do have a breaker in line. Take a meter and check the resistance of your body vs the voltage and amperage of the battery and you should come up with the actual numbers. Look up ohms law for ur answer.
Well that sounds no fun at all. I'm going to try mine soon but instead of a 9v battery I will probably use 220 with 30 amps. I'll let you know how it turns out

DUH IT WON'T WORK WITH AC DONT YOU KNOW ANYTHING ABOUT ELECTRICITY!
I kid.
I just used a light slurry of table salt and Starsan with a 9VDC wall cube as a supply. Worked great on my aluminum kettle.
Human body internal resistance is 300 to 1000 Ohms
Human body dry skin resistance is 1000 to 100,000 Ohms
12V across 300 Ohms = 4mA
Cardiac arrest can occur at 75mA
I work with UL Listed products and anything below these voltages are considered intrinsically safe:
- 30V AC
- 42.4V DC
Worst case with wet skin your body is about 300 Ohms so at 12V that will give you 4mA, well below the 75mA cardiac arrrest value.
Etch on in safety
I agree with your conclusions, but 12V with 300 ohms yields 40 ma, not 4 ma.
I know it is late in the thread, but hopefully someone will have an answer. Isn't everyone here measuring their pots with cold water? Boiling water will have more volume won't it? Does that matter here? How do you account for it?

for all you anal brewers that did this etching with the 1/8" lines.....is your level at the top or bottom of the line, or is it at the bottom of the number.?Just asking as some of you are now worried about the level at boil temp, or temp out of the faucet. And you had better do your etching after you add all your valves, sight glasses, thermometers as it will change the volume.

Quick question. Could I use the below alarm clock cord (plugged in) for doing this? My first thought is no, but I dont know much about electricity so I wanted to make sure.
