Radu Motisan has been building a global environmental surveillance network which first monitored radiation levels, and since has added the ability to measure air quality. He believes that people need to be more aware of the environment around them in a similar way that society has awakened to issues about personal fitness and health. We can’t do this without a simple and reliable way to measure the environment.
He discussed the project at length during his presentation at the 2015 Hackaday SuperConference. Watch that talk in the video below, then join us after the break for more details on the hardware and infrastructure that collects and presents the data publicly.

This year’s Hackaday Prize included a category for the Best Product, and there is perhaps no project that has inspired more people to throw money at their computer screens than [Oscar Vermeulen]’s PiDP-8/I. It’s a replica of the PDP-8/I from 1968. Instead of discrete electronics driving the blinkenlights and switches on the front of this computer, [Oscar]’s version uses a Raspberry Pi and the incredible SIMH emulator for dozens of old mainframes and minicomputers. It is, for all intents and purposes, a miniaturized version of a 50 year old computer that will fit on your desk and is powered by a phone charger.
Check out the video of [Oscar]’s talk below then join us after the break for more discussion of his work.

Humans may all have the same overall form, but when we need to find a suitable replacement for a missing limb, it’s clear that between the variety of finger-lengths and hand-breadths, a one-size-fits-all prosthetic just wont cut it. OpenBionics puts a spin on today’s approach to prosthetics, putting forth a framework of tools that’s flexible enough to fit the spectrum of hand shapes and enables us to create our own prosthetic at home that can meet the challenge of most everyday tasks.
Minas Liarokapis of the OpenBionics team gave a talk at this year’s Hackaday SuperConference which covered the design considerations and unique features of the project. This incredible work was recognized with 2nd Prize in the 2015 Hackaday Prize. Watch Minas’ talk below, then join us after the break as we cover more details that went into developing this prosthesis.

Hot on the heels of the 2015 Hackaday prize, with its theme of “Build stuff that matters”, comes another opportunity for hackers to make a difference. But you’ve got to think like Mother Nature for the 2016 Biomimicry Global Design Challenge.
The aim of this challenge is to transform the global food system using sustainable approaches that emulate natural process. Entries must address a problem somewhere in the food supply chain, a term that could apply to anything from soil modification to crop optimization to harvest and storage technologies. Indeed, the 2015 winner in the Student category was for a passive refrigeration system to preserve food in undeveloped areas. It’s a clever two-stage system that uses an evaporative cooling loop inspired by the way an elephant’s ears cool the giant beast, and by use of a wind-capturing funnel that mimics how animals as diverse as termites and meerkats cool their nests.
In addition to the Student category, the challenge has an Open category for teams of any composition. Up to 10 teams will be selected from the Open category to proceed to the Accelerator phase, where they’ll receive support for a six to nine month development of their design into a marketable product. The winner will be awarded the $100,000USD Ray of Hope prize, endowed by the Ray C. Anderson Foundation.
We’d love to see someone from the Hackaday community take home the 2016 prize, and there are plenty of 2015 Hackaday Prize entries that may be eligible. The deadline for submissions is 11 May 2016, so get a team together and get to work.
As with any proper hardware con, the Hackaday Supercon needed a badge, and preferably one that was electronic. This conference centered around hardware creation, and the badge was no exception.
Designed on a tight timeline, it was possible to deliver a PCB badge for the attendees but it didn’t include microcontrollers, FPGAs, or software defined radios. This blank slate was the foundation for a completely unconstrained freestyle electronics soldering session.
The front of the badge includes a matte black solder mask with Truchet tiles of traces. Put multiple badges edge-to-edge and the pattern continues indefinitely. Inside of each curved trace is a through-hole via and those makes up a grid of holes on the back of the badge. On that back side there are also two rectangular grids that presented a nice area to which hackers soldered their components.
More than a few people took up the challenge of hacking their badge, and despite a strange pitch for the through holes (0.230″), and traces that didn’t go anywhere, there were some amazing builds. I would go so far to say that the badge hacking at the Supercon was the best I’ve ever seen, and this includes DEFCON and CCC.

This week we’ve covered the Grand Prize and Best Product winners of the 2015 Hackaday prize: Eyedrivomatic and Vinduino. These are both amazing and worthy projects, but the real story of the Hackaday Prize isn’t about the prizes: it’s about nine months during which talented people worked toward a common good.
If you didn’t have a chance to attend the Hackaday SuperConference, here is the video of the ceremony. Take a look at the presentation which was made in front of a packed house of about 300 attendees. Then join us after the break for a look back on the last nine amazing months.

The 2015 Hackaday Prize included something new: a prize for the Best Product. The winner took home $100k in funding, a six-month residency at the Supplyframe Design Lab in Pasadena, and help turning a budding product into a full-grown success. And the winner is…
Water is a crucial element for farming: the plants need enough, but not too much. Water is also an increasingly precious resource all over the world. In California, five times as much water is used in agriculture as is used by residential consumers. A 25% reduction in agricultural use, for instance, would entirely offset all urban water use. With this in mind, a number of California farmers are trying to voluntarily reduce their water consumption. But how?
One important development is targeted irrigation. Getting precisely the right amount of water to each plant can reduce the fraction lost to evaporation or runoff. It’s a small thing, but it’s a very big deal.
Cue Vinduino, a long-running project of “gentleman farmer” and hacker [Reinier van der Lee]. As a system, Vinduino aims to make it easy and relatively inexpensive to measure the amount of water in the soil at different depths, to log this information, and to eventually tailor the farm’s water usage to the plants and their environment. We were able to catch up with [Reinier] at the Hackaday SuperConference the day after results were announced. He shared his story of developing Vinduino and recounts how he felt when it was named Best Product:
The product that won Best Product is simple, but very well executed. It’s a hand-held soil moisture sensor reader that couples with a DIY soil probe design to create a versatile and inexpensive system. All of the 2015 Best Product Finalists were exceptional. Vinduino’s attention to detail, room for expansion, and the potential to help the world pushed this project over the top.
