Interestingly, I've *fixed* video cards that way... We have a client at work who bought 100 of these old IBM ThinkCenter's, but they need to run dual monitors on them.. For some reason they refuse to work with 90% of the video cards we put in them until I came up with the crazy idea that their PCI-E slot was actually 1x, and we were putting 8x and 16x cards in them... I took some scotch tape and covered all but pins 1-18 (IIRC), popped it in, and it works great. I've modded a few dozen cards now and have never had a problem. I suppose I could have dremeled them, but scotch tape was easier.
IMO, if a person is too immature to make up his or her own mind about whether or not it is a good idea to burn your skin with a high power laser, that person is not mature enough to own a laser at all.
I think eye and plane/other vehicle safety is different since many people do not know the actual dangers of a laser here and think "it's just a light" or "it can't reach that helicopter".
This is more like "should I cut myself with this knife or not". Unless it causes cancer or some other hidden threat, which I doubt since 405nm is still pretty far from cancer-developing wavelengths, I do not see the problem of posting this.
I read a few articles about melanoma being caused by laser treatments, but IIRC it was due to IR and they found out it was a condition which looked like melanoma but was not dangerous.
You're all a bunch of babies. This is nowhere near as stupid as a lot of other DIY tattoo options... I've heard of people simply slicing a deep cut in their skin, and pouring in ink... I've watched people repeatedly stab themselves with a needle... I've watched someone give themselves a scarification using a 60W soldering iron. People do these things without anesthetic, using dirty unsanitized tools. A laser is hundreds of times safer than all of the above, and likely much less permanent.
Anyways, if any of you have access to a professional laser cutter, you can produce whatever design you like, plus you get accurate control over the depth and intensity of the burn.
