That's an awesome DIY...thanks for sharing!
Is this like a regular cell phone charger?
[...]But you'd probably feel it if you licked it like a 9v battery!
Direct current (DC) is a "safe" type of electric. You can touch either side of a DC circuit and not be harmed. The only time you can be harmed (in high voltage instances) by a DC current is if you complete the circuit (holding both wires at the same time). Since this project requires a really low voltage (under 24V), you'll be fine.
Hook up the POSITIVE lead directly to your kettle.
Attach the NEGATIVE lead directly to a Q-tip, making sure the wires will be touching the vinegar solution.
This etching method described by the OP is not going to hurt you. Just don't try and use a car battery charger. Low voltage. Lots of amps. Current kills.
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.

I'm having issues trying to get this to work and the only thing I can think of is that I am using sea salt instead of plain old salt, would that make a difference? I didn't have any spare power cords either so I just striped an extra extension cord and used those wires, that would work for wiring right?
Has anyone done a Keggle yet that cares to share some pictures?
I'll be marking mine on saturday.
You guys better have pictures up on Saturday night now or we'll be coming after you for them In all seriuosness though, looking forward to seeing a keggle done, and how easy/hard it is to read without a "big" open top!Me too! Will post pics once done.
There was a reddit post on reasons not to do this. If I can find the link, I'll post it
