Andrew,

I am not an attorney but I am almost certain you won't get sued for giving this kind of information away. Otherwise hobby electronics magazines, who actually sell the information, would have long ago ceased to exist as they depend on people like you for their projects. They print stuff like this with a simple warning that high voltages are accessible so use your own "good judgement".

Take a look at the July 2012 projects issue of Elektor USA and you will find four or five line operated projects that are not transformer isolated, usually powered by a resistor/capacitor direct to the power line. And since these have to operate in Europe as well as the US, they expose as much as 230V.

So don't sweat it.

Line voltage safety:  We have been using electricity for well over 100 years.  If anyone is doing electrical and electronic work and still  doesn't know you can get a shock from line voltages, then he pretty much deserves to get zapped.

Challenge to the paranoid! 

Getting sued?   Magizines (hobby and professional) have been publishing plans for projects for well over a century.   Can anyone name a single case where an author has suffered any civil or criminal judgment because someone attempted to replicate the published design and got into trouble?

Thank you all so much for your kind words. They make me feel a lot better. Fortunately, my next project does not operate directly off the power line. I don't know when it will be published.

Good point, J-allen. I don't think Andrew has anything to be concerned about here. People build gadgets at their own risk, even if they come from a published source.

Good point, Gafisher. Everybody in product development seems to be suing and getting sued these days -- Sony, Apple, MS, Amazon, Samsung. They all have one thing in common -- $$$. I don't believe the small inventor is going to get sued simply because there is no possibility of a big payday.

Good suggestion, John. We're looking forward to receiving more gadgets from you when you're ready.

Yes, I do plan to make some more gadgets.  Currently, I'm desinging a 3000 lumen flashlight with a detachable burning laser.  Would that make a good project?

Sounds great, John. We look forward to seeing it. What a way to spend your summer vacation -- creating gadgets.
