Tattoos are an ancient art, and as with most art, is usually the domain of human expertise. The delicate touch required takes years to master, but with the capacity for perfect accuracy and precision movements, enlisting a robotic arm and some clever software to tattoo a willing canvas is one step closer thanks to the efforts of [Pierre Emm] and [Johan da Silveira].
They began by using a 3D printer modified to ‘print’ with a tattoo needle. Catching the interest of the Applied Research Lab at Autodesk, the next logical step was to use an industrial robot arm get a human under the tattooing machine — dubbed Tatoué — after scanning the limb in question and loading it into Dynamo, their parametric design environment to map the design onto the virtual limb.

[Philip] got a tattoo of the Hackaday Skull ‘n Wrenches. His job is mostly office work in long sleeves, so everything’s good. The original logo was drawn in Flash by [Phil Torrone] of Adafruit, and reworked into a slightly more modern file format by [Elliot]. Yes, a skull and wrenches is a biker symbol and can be found in the emblem for a few military divisions (mostly for armored support). The Hackaday logo is by far the most cartoonish of all of these Jolly Wrenchers.
Speaking of scrawling the Hackaday logo on stuff, [Rodrick] was bored and needed a distraction last Saturday night.
We’ve seen perpetual motion machines on Kickstarter, and we’ve seen projects that may actually have some basis in reality. We’ve seen 12-year-olds put up a Kickstarter for a new gaming computer, and we’ve seen campaigns to build a bar in some random guy’s basement. There is only one project we haven’t seen on Kickstarter, until now: a campaign to build another crowdfunding platform. It is the Shortening of the Way.
You want a fail? This is a fail. [Chris] is working on a device that combines the familiar Arduino pinout with a CAN transceiver. A good idea, but if you build a PCB, you’re going to need traces. [Chris] sent his files off to our favorite purple board house and got back a sheet of copper laminate with holes in it. A good reminder to check your Gerbers before sending them off.
Live around Denver? There’s a hackerspace in Broomfield, Colorado that’s looking for a new space. They have a Kickstarter for the lease and they’re looking for some people to fill their space.
You kids out there with Pro Tools and Logic don’t know how good you have it. Back in the day, audio was recorded on magnetic tape with exacting mechanical devices called multitrack recorders. [Fran] fished her Otari 8-track recorder out of storage, and it’s a thing of beauty. Also out of storage is a 300 lb+ plate reverb.
ENSCI les Ateliers, the famous design school in Paris, had a “Public Domain Remix” and hackathon recently, with teams splitting up to remix public domain and other free-to-use IP in projects. Most of the teams came up with similar ideas, but one team went above and beyond the call of duty; they turned a 3D printer into a tattoo machine, capable of inking a real, live human test subject.
The build began by plotting a circle with a pen onto a piece of paper. This evolved into printing a tool holder for a tattoo machine graciously provided by an amateur tattoo artist. Tests with “artificial skin” (any one care to hazard a guess at what that is?) were promising, and the team moved on to a human guinea pig.
The biggest problem the team faced is that humans aren’t flat. They tried a few tricks to tighten the skin around the area to be tattooed – metal rings, elastics, and finally the inner tube from a scooter. In the end, the team was able to tattoo a small circle on the forearm of the test subject.
It’s an extremely simple and small tattoo, and scaling this build up to a sleeve would be difficult. A better solution would be to create a point cloud of an arm before going for a much larger tattoo.

Here’s something we thought we’d never see: a robot that turns a computer drawing into a tattoo on the user’s arm.
The basic design of the robot is a frame that moves linearly along two axes, and rotates around a third. The tattoo design is imported into a 3D modeling program, and with the help of a few motors and microcontrollers a tattoo can be robotically inked on an arm.
Since the arm isn’t a regular surface, [Luke] needed a way to calibrate his forearm-drawing robot to the weird curves and bends of his ar. The solution to this problem is a simple calibration process where the mechanism scans along the length of [Luke]’s arm, while the ‘depth’ servo is manually adjusted. This data is imported into Rhino 3D and the robot takes the curve of the arm into account when inking the new tat.
Right now [Luke] is only inking his skin with a marker, but as far as automated tattoo machines go, it’s the best – and only – one we’ve ever seen.
I had an idea for keeping things interesting on this long road trip through the southwest. I was going to gather a few bits from each hackerspace and build something using minimal tools while we were driving down the road. I settled on the idea of a really simple “jailhouse” tattoo gun. I knew I could build one from parts I could source very easily and that I wouldn’t need much in terms of tools to make it happen.

This bar code tattoo was sent into us by [Lifespan]. Before going under the needle, [Lifespan] didn’t care much for tattoos. After seeing this video he realized that a tattoo could have dynamic content through domain redirection.
[Lifespan] spent a lot of time going over the different styles of 2D bar codes. QR codes were deemed ugly because of the three large squares in the corners. An EZ Code, like the one in his YouTube inspiration, are a proprietary format that must be read with a ScanLife app. He eventually settled on a Data Matrix bar code because of its open format and ubiquity in business and industry. To make the tattoo dynamic, [Lifespan] made the tattoo point to 5id5.com. With a little bit of smart phone wizardry, that domain can be redirected to any URL in a moments notice.
Like all well-planned tattoos, he found himself a very good artist to do the piece. [Connor Moore] managed to ink some skin at 15 dpi, which was a little risky, but the results came out great. While it’s not scarification via a laser cutter, barring fading this tattoo is technologically future proof.
Prison inmates have a history of being gruesomely resourceful hackers. The toothbrush shiv comes immediately to mind. One such inmate in the UK wanted to offer tattoos to his fellow convicts so he came up with a tattoo gun using a PlayStation for parts. The crude setup involves a sharpened ballpoint pen and the use one of the motors from the optical drive to move it up and down. The inmate didn’t document his work for us but there are other examples of this method available. Even with modern hardware, ink seems a little 20th century when compared to laser tats.
