There are ways to create tattoos that do not involve machines. I think that when you're not using a machine, using one hand becomes more feasible.
There's the original Polynesian technique, of course, where the needle is at the end of a stick and you tap the back of the stick with a small hammer, making one dot at a time. It's extremely time consuming, but I've seen some stunning designs done with that sort of stippling. Of course, it still takes two hands, one to steady the needle bar and one to tap with the hammer. That's where the word tattoo comes from, the tapping sound of the hammer. (probably combined with the sound of the customer going "Ooh! Ooh!" with each blow.
Some kitchen scratchers use a pencil with the eraser jammed full of sewing needles and wrapped with twine or thread to soak up ink. You could theoretically wield that device with one hand if you really jabbed it in hard, but the skin still needs to be stretched tight, or the needles bounce off the surface like it was a sheet of rubber*. You'll get the sensation of being poked, but the area will only turn a little gray, if it takes any color at all. Homeboy methods like that also generally involve the use of cheap substandard inks, that turn grey/green with repeated exposure to the melanin released in the suntanning process.
I have seen one homemade electric tattoo machine made from a tiny motor and a ballpoint pen. The guy who brought it in had had it used on him and said it hurt like hell. No doubt. I'm sure that was very sanitary, too.
*jabbing a needle with that kind of pressure increases your chances of a blowout - the ink is supposed to go between the second and third layers of epidermis - any deeper and you're injecting ink into the fatty tissue, which is like shooting it into a cube of gelatin, it spreads out instead of keeping a tight line, and once that happens, there's no fixing it. It's coverup time.
