Of course she’ll be talking about The Hackaday Prize with all of the incredible entries so far and the amazing opportunities waiting for you as THP continues through the summer. But [Sophi’s] life experience runs far-and-deep and so will the conversation. She is an Electronics Engineer, an Artist, and a huge part of the Hackaday crew. This year she landed a grant to bring one of her projects to life for Burning Man (and to document the process which we’re really excited about). She’s brewing up a new project involving Quadcopters and the technology [Alan Yates] has been working on for Valve. And [Sophi] frequently works on projects like Breathe that delight us with her creativity.
But hey, we better leave some of it for the show. The live link is above, here’s the Adafruit page as well.
Lunar dune buggy rides, piloting the most powerful machine made by humankind, stuck thrusters, landing, eating, sleeping, and working on the moon. It does not get any more exciting than the Apollo program! I was recently given the opportunity to sit in on the MIT course, Engineering Apollo: the Moon Project as a Complex System where I met David Scott who landed on the moon as commander of Apollo 15. I not only sat in on a long Q and A session I also was able to spend time with David after class. It is not every day you that you meet someone who has landed on the moon, below are my notes from this experience.
Open Science has been a long-standing ideal for many researchers and practitioners around the world. It advocates the open sharing of scientific research, data, processes, and tools and encourages open collaboration. While not without challenges, this mode of scientific research has the potential to change the entire course of science, allowing for more rigorous peer-review and large-scale scientific projects, accelerating progress, and enabling otherwise unimaginable discoveries.
As with any great idea, there are a number of obstacles to such a thing going mainstream. The biggest one is certainly the existing incentive system that lies at the foundation of the academic world. A limited number of opportunities, relentless competition, and pressure to “publish or perish” usually end up incentivizing exactly the opposite – keeping results closed and doing everything to gain a competitive edge. Still, against all odds, a number of successful Open Science projects are out there in the wild, making profound impacts on their respective fields. HapMap Project, OpenWorm, Sloan Digital Sky Survey and Polymath Project are just a few to name. And the whole movement is just getting started.
While some of these challenges are universal, when it comes to Biology and Biomedical Engineering, the road to Open Science is paved with problems that will go beyond crafting proper incentives for researchers and academic institutions.
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.
We had a chance to interview [Grant Imahara] at the 2014 Electronica conference in Munich, Germany. If you don’t recognize [Grant’s] name you’ll probably recognize his face. He’s been on the cast of the television show Mythbusters for about 10 years now. We heard recently that he was leaving the show and that’s how we crossed paths with him.
[Grant] has signed on with Mouser Electronics to promote their Empowering Innovation Together program. They hosted him on a press junket at their booth and since we have a good relationship with Mouser they offered Hackaday an interview slot.
We had a lot of fun talking to [Grant]. Unfortunately the wireless microphones the Mouser videographer was using were picking up a lot of interference. This didn’t directly affect our recording setup as we were using a handheld voice recorder, but we kept getting interrupted as they tried to figure out the problem. Still, as you can see from the video below, we managed to get all the way through a few questions about [Grant’s] introduction to electronics at a young age, his first job out of school working for Industrial Light and Magic, and his advice to others who want to get into electronics and specifically robots. He mentions his early learning was guided by the books of Forrest Mims and that these days learning about electronics is no more than a keyword search away.
The Hackaday European tour continues, this time in Prague with Josef Průša (Google translate), core developer in the RepRap project, feature at all the Maker Faires and cons, and creator of his namesake, the Prusa Mendel and i3 printers.
[Prusa]’s involvement with the RepRap project started with a RepRap Mendel, the second iteration of RepRap hardware, but the first popular and easy to build version. [Jo] found the Mendel rather difficult to build, so he loaded OpenSCAD and started to design his own version of the hardware. This version became the de facto standard RepRap for a few years, with many inspired by and derivative printers making their way to hackerspaces and workshops around the world.
A few years ago, [Prusa] was one of the first to make a complete break with the traditional ‘threaded rod and nut’ construction of RepRaps with the introduction of the Prusa i3. This was the first model that had a metal plate as the frame, another feature that would be seen in dozens of other models. It’s not something that was without controversy, either; using a metal plate for the frame doesn’t allow for as much self-replication, something that’s a core value of the RepRap project. That didn’t matter to the community; the Prusa i3 or a similar design is the third most popular printer on 3Dhubs.
What’s the future of the Prusa name? There is an i4 in the works, and I’m pretty sure that’s all I can tell you. Someone already bought the Prusai4 domain, so there may be a name change.
In the interview below, [Prusa] goes over his involvement with the RepRap project, his business, what he considers to be the latest advances in 3D printing for the past year, what the worst things about the 3D printing scene is (it’s Kickstarter), the state of the RepRap project, and thoughts on SLS, DLP, and SLA printing technologies. Video below.
There are a surprising number of spectrometer projects out there on the Intertubes, but most of these setups only measure the absorption spectrum – literally what wavelengths of light are absorbed by the material being measured. A Raman spectrometer is completely different, using a laser to illuminate the sample, and measuring the scattering of light from the material. It’s work that has won a Nobel prize, and [fl@C@] built one with a 3D printer.
Bio below, along with the final video that was sent around to the judges. If you’re wondering who the winner of The Hackaday Prize is, even I don’t know. [Mike] and a few Hackaday overlords do, but the rest of us will remain in ignorance until we announce the winner at the party we’re having in Munich next Thursday.
