While hardcore body-hackers are starting to freak us out with embedded circuit boards under their skin, a new more realistic option is becoming available — temporary tech tattoos. They’re basically wearable circuit boards.
Produced by [Chaotic Moon], the team is excited to explore the future of skin-mounted components — connected with conductive ink in the form of a temporary tattoo. And if you’re still thinking why, consider this. If these tattoos can be used as temporary health sensors, packed with different biometric readings, the “tech tat” can be applied when it is needed, in order to monitor specific things.
In one of their test cases, they mount an ATiny85 connected to temperature sensors and an ambient light sensor on the skin. A simple device like this could be used to monitor someone’s vitals after surgery, or could even be used as a fitness tracker. Add a BLE chip, and you’ve got wireless data transfer to your phone or tablet for further data processing.

[Tom Lombardo] is an engineer and an educator. When a company sent him a Dino Pet–a bioluminescent sculpture–he found it wasn’t really usable as a practical light source. He did, however, realize it would be an interesting STEAM (science, technology, engineering, art, and math) project for students to produce bioluminescent sculptures.
The lamps (or sculptures, if you prefer) contain dinoflagellates which is a type of plankton that glows when agitated. Of course, they don’t put out a strong light and–the main problem–you have to agitate the little suckers to get them to emit light. [Tom] found that there was a mild afterglow when you stop shaking, but not much. You can get an idea of how much light they make in the video below. The idea for a school project would be to make practical ambient lighting that didn’t require much input power to agitate the plankton.

“We accept pain as a price of doing business, even if it is just for aesthetic purposes. You want to put a magnet in your finger, a doctor will ask you why; a mod artist will ask when you can start.” As with many other people who are part of the growing grinder movement, [Adam] has taken a step that many would consider extreme – he’s begun to augment his body.
Grinders – men and women who hack their own bodies – are pushing the boundaries of what is currently possible when it comes to human augmentation. They’re hackers at heart, pursuing on an amateur level what they can’t get from the consumer market. Human augmentation is a concept that is featured heavily in science fiction and futurism, but the assumption most people have is that those kinds of advancements will come from medical or technology companies.
Instead, we’re seeing augmentation begin in the basements of hackers and in the back rooms of piercing studios. The domain of grinders is the space where body modification and hacking meet. It mixes the same willingness to modify one’s body that is common among the tattooed and pierced, and adds an interest in hacking technology that you find in hackerspaces around the world. When those two qualities intersect, you have a potential grinder.

Once upon a time, the aspiring nerdling’s gift of choice was the Gilbert chemistry set. Its tiny vials of reagents, rack of test tubes, and instruction book promised endless intellectual stimulation and the possibility of stink bombs on demand. Now a new genetic engineering lab-in-a-box Kickstarter, with all the tools and materials needed to create your own transgenic organisms, may help the young biohacker’s dreams come true.
The Kickstarter has been wildly successful. The initial goal was $1200AUD was met in a day, and currently stands at almost $6200AUD. Despite that success, color me skeptical on this one. Having done way more than my fair share of gene splicing, there seem to be a few critical gaps in this kit. For example, the list of materials for the full kit includes BL21 competent E. coli as the host strain. Those cells are designed to become porous to extracellular DNA when treated with calcium chloride and provided with a heat shock of 42°C. At a minimum I’d think they’d include a thermometer so you can control the heat shock process. Plenty of other steps also need fairly precise incubations, like the digestion and ligation steps needed to get your gene into the host. And exactly what technique you’d be using to harvest DNA from the animal, plant or fungal cells is unclear; the fact that most of the techniques for doing so require special techniques leads me to believe there’s a lot less here than meets the eye.
To be fair, I’ve been off the lab bench for the better part of two decades, and the state of the art has no doubt advanced in that time. There could very well be techniques I’m not familiar with that make the various steps needed to transform a bacterial culture with foreign DNA trivial. It could also be the case that the techniques I used in the lab were optimized for yield and for precise data, while the GlowGene kit provides the materials to get a “good enough” result. I hope so, because a kit like this could really expand the horizons of hackerdom and start getting the biohacking movement going.
In March of 2014, I knew my eight year old daughter was sick. Once borderline overweight, she was now skeletally thin and fading away from us. A pre-dawn ambulance ride to the hospital gave us the devastating news – our daughter had Type 1 diabetes, and would be dependent on insulin injections for the rest of her life.
This news hit me particularly hard. I’ve always been a preparedness-minded kind of guy, and I’ve worked to free myself and my family from as many of the systems of support as possible. As I sat in the dark of the Pediatric ICU watching my daughter slowly come back to us, I contemplated how tied to the medical system I had just become. She was going to need a constant supply of expensive insulin, doled out by a medical insurance system that doesn’t understand that a 90-day supply of life-saving medicine is a joke to a guy who stocks a year supply of toilet paper. Plus I had recently read an apocalyptic novel where a father watches his 12-year old diabetic daughter slip into a coma as the last of her now-unobtainable insulin went bad in an off-grid world. I swore to myself that I’d never let this happen, and set about trying to find ways to make my own insulin, just in case.

Few things have managed to capture the imagination of hackers and engineers around the world the way Synthetic Biology did over the last couple of years. The promise of “applying engineering principles to designing new biological devices and systems” just seemed way too sci-fi to missed out on, and everyone jumped on the bandwagon. All of a sudden, the field which used to be restricted to traditional research organizations and startups found itself crowded with all sorts of enthusiasts, biohackers, and weirdos alike. Competitions such as the International Genetically Engineered Machine (iGEM) paved the way, and the emergence of community spaces like GenSpace and BioCurious finally made DNA experimentation accessible to anyone who dares to try. As it often happens, the Sci-Fi itself did not go untouched, and a whole new genre called “Biopunk” emerged, further fueling people’s imagination and extrapolating worlds to come.

The team behind 25C3 has published the first draft of this year’s schedule. The annual Chaos Communication Congress is happening December 27th to 30th in Berlin, Germany. There are plenty of interesting talks already in place. We’re spotting things we want to attend already: The conference starts off with how to solar power your gear, which is followed by open source power line communication. A TOR-based VPN, an open source BIOS, rapid prototyping, holographic techniques, and running your own GSM network are on the bill too.
We’ll have at least three Hack a Day contributors in attendance. Last year featured two of our favorite conference talks: [Drew Endy]’s Biohacking and the MiFare crypto1 RFID crack. We hope to see you there.
