Step 6: Safety!

I have a failed space invader attempt on my left arm.

I stoopidly forgot that the laser beam was completely exposed on the left side before it hit the final mirror.

Shortly after the space invader etch started, I noticed a lot of smoke. This smoke was not coming from the etch, but from the left side of the cutter, where the upper part of my left arm was resting. When I looked over, I saw that my shirt was smoldering.

I was so focused on keeping my forearm in place (as to not ruin the tattoo), I did not notice that the laser was no longer etching it, but rather cutting a gash into my upper left arm.


Needless to say, I only etched my right arm from that point on.

Uhh... instead of the pain, skin damage, possible permanency and not great contrast for visibility, why not rig up an inkjet printer to put artwork on your skin? Get tired of the design, wash it off. And you can do different colors too.
hmmm...... this just screams cancer
 Hehe

I dont recommend alcohol based products before the etch! Your entire hand could catch on fire!

You fall down into a sewer and die-- thats a comedy. I cut my finger-- that's a tragedy.
"By the sewer I lived, By the sewer I died. They thought it was murder, But is was 'sewer-side'."
Amen! =D

I have heard be exposed to lasers for long periods of time can give you skin cancer.
I have heard that exposure to lasers for very short periods of time can remove appendages:

That is awesome. It's not stupid. People have been modifying their bodies for centuries. It's just another way of doing it (people could say poking holes in your ears is crazy or putting a foreign substance on your nails to make them pretty is dangerous because it's flamable, etc). My hubby & I think it's a great idea. Of course, it could be better if they figured out a way to make the machine more specialized in doing it on skin.
how long does the etching last? is it permanent? Or does it just peel off after a while.

if you had a bad enough wound, you could use this to quickly coterize it.

(or however heat treating wounds to stop the bleeding is spelled.)
