Geekologie reader Brian loves himself some Cisco. Lucky for him the design kind of resembles a post-Apocalyptic barcode brand-like symbol or something, so it could have the legs to last a lifetime. Unlike, you know, Zune guy. [Geekologie]

As great as it seems, this concept is seriously creepy because it powers itself by converting the glucose and oxygen found in blood into electricity. But somehow getting your blood sucked by a gadget is worth it for the endless potential applications. I’d probably just end up using it to moderate comments, but what would you do first with your implant? [Core77 via Geekologie]

Dabe Alan got a vintage gadget tattoo of his own, but he shot the process in time lapse with a very modern Canon 5d Mark II before editing this video in Final Cut Pro. Ouchies. [Flickr]

Vintage Gadget Tattoos

I may have an original 1984 Macintosh on my work desk, but I would be out of my f—king mind to get a tattoo of it forever burnt in my skin. A ZX Spectrum, on the other side, is a very likely possibility. It just depends on the amount of Zacapa rum and Margaritas this weekend.

Note to the VHS tattoo dude: If you are going to drill a video tape into your skin for the rest of your life, at least pick a Sony Beta. [Obsolete]

Extremely nerdy tattoos are popping up more and more these days. Not that you are crazy enough to get one, but let’s say you blacked out after a drunken evening and woke up with a gadget tattoo. What gadget might it be…and where would you find it?

Keep in mind that tattoos of anything that falls under the nerd culture umbrella is acceptable—from physics equations to portraits of Bill Gates with the words “XOXO Forever” underneath. Bonus points if you actually have a tattoo in this category.

Lou wanted a free Palm Pre. So, naturally, he got a Palm Pre tattoo. Wait, what?

This isn’t some guy who’s covered in tattoos already, either. This is Lou’s very first and only tattoo, a big ugly Palm Pre right on his shoulder. He will get his precious smartphone courtesy of PreCentral.net, but you’ve gotta wonder how long it’ll be before he starts trying to get a different website to pay for the laser removal. I mean, for chrissakes, the free phone is only worth $US199! Come on, Lou, you could have gotten so much more for an equally embarrassing tattoo if you only knew how to market yourself.

So what do you think: is this more or less sad than Zune tattoo guy? I think Zune guy is still the saddest, as he didn’t get free anything for his permanent branding (that he’s since changed into something perhaps even more regrettable). [Pre Central]

Some tattoos are sexy, and some are just flat out creepy—but I’m not sure what to think about the Born Oppenheimer Approximation, 3-D Schroedinger Equation and Schroendinger Equation’s solution tattooed on this dude’s back. [Discover via Geeks Are Sexy]

We don’t write about many tattoo machines here on Giz, preferring to keep our gelatinous arms free from skin-breaching contraptions. But the Neuma Hybrid has an interesting pitch.

The original Neuma was the world’s first air-driven tattoo machine. Its design somehow promised a less painful tattoo (we’re confused as to how since the needle is still a needle) and it was crafted from solid aluminium for easy medical-grade sterilization. The new Neuma Hybrid is lighter—a mere 105 grams—and it operates both under air pressure and electricity…which is somewhat/almost/kinda/not really at all like your Prius.

On the spec sheet, it all sounds great. But do we have any tattoo artists in the audience who might care to elaborate? [RKS via Yanko Design]
