Discounts in all Zolertia’s packs

From Zolertia:

We have been awfully quiet but we are pleased that the reason behind this were projects and challenges keeping us busy since early 2012, so after a ton load of work followed by well deserved vacations we can finally give you some updates about what’s going on and our latest additions to the Zolertia’s ecosystem, kicking it with a 5% off all our packs.

We are re-launching some of our well known packs, such as the Discovery Pack Silver AAA (3xZ1) and theProfessional Pack Bronze (10xZ1),
offering a juicy 5% off discount, and introducing our new top-sellers Pack Lithium and Titanium, at a discounted price too, featuring:

Professional Pack Titanium:

This pack was conceived by request of our clients, demanding a complete solution to immerse themselves into development and production in a faster and easier way, using a complete set of sensors and actuators ready to work outside-the-box, development tools fitted to ease on-field testing such as the Starter platform, and the recently updated Gateway to interconnect your Wireless Sensor Network projects to other networks such as Internet.

Professional Pack Lithium:

Our experience in real-world deployments allowed us to design this new pack, allowing researchers, developers and integrators more flexibility regarding on how to provide power to their projects, for example using solar panels, reducing the overhead of replacing batteries and having to mobilize to the deployment site to replace those.

The battery charger and the battery itself are fully integrated into the enclosure, suitable for testbeds, demonstrators and ready-to-deploy projects without having to worry about component placement.

A led charging indicator on the enclosure allows to inspect the status of the battery (charging, discharging, charged) more readily.

TinyDuino Microcontroller Is Smaller Than a Quarter

Arduino is probably the world’s most popular open source physical computing platform. The little microcontrollers show up in everything from wild art projects to serious home automation efforts. It’s great and all, but couldn’t it be … smaller? Electrical engineer Ken Burns thought so, and got to work on the TinyDuino.

TinyDuino is a fully Arduino-compatible hardware platform, complete with expansion shields (add-on boards that have specific sensors or lights, for you non-robot designers). But where an Arduino Uno is around the size of a credit card, the TinyDuino is smaller than a quarter, and its sibling the TinyLily is the size of a dime. The TinyDuino line is designed around three core elements: size, affordability, and expandability. The idea, says Burns, is to open up Arduino to a whole host of applications that simply aren’t possible with the larger board.

The seeds of TinyDuino were planted when Burns was working on creating smart sensors. The goal was sensors that would be plug and play, with on-board intelligence that allowed them to handle all the hard stuff, like reading data, calibration, and formatting the output. “For a typical hobbyist, this would mean you could just plug in any sensor, whether it’s temperature, pressure, light–whatever, and your system would read it out and know what it was and the units it was in.”

Burns says that Arduino was a natural fit as a basis for the work. When he shared his progress with friends and members of the SYN/HAK hackerspace, “it became pretty apparent that there were others that were very interested in having very tiny Arduino compatible processor modules,” Burns says. Focus switched over to designing a family around this core concept.

The TinyDuino is an exercise in design extremes. When you start cutting a hardware board down to the size of pocket change, it forces you to make a lot of serious decisions about what features are needed. In order to cut the TinyDuino down to size, Burns says, they moved a lot of the default affordances of the Arduino hardware, like the USB connector, on to TinyShields. (A similarly-shrunken Arduino project, the Digispark, has the USB plug built in, similar to a small thumbdrive ). TinyShields are an intensification of the shield paradigm that is already an important part of Arduino hardware.

“If you look at the board itself,” says Burns, “it’s really just a core processor that brings out signals to pins.” Ordinarily, those pins need to be attached (often through soldering) to electronics that can process the signals and turn them into motion, light, sound, WiFi, etc.

A Decade of TinyOS Development

OSDI 2012 has an interesting paper on the evolution of TinyOS over the past 10+ years. It looks at both technical and social decisions that contributed to the success of TinyOS. The paper also looks back and evaluates what worked, what didn’t, and why. It’s rare to see papers at technical conferences talking about the non-technical aspects of large software development projects, so should be an interesting read. You can find the paper here.

Thingsquare Announces Software to Simplify the Internet of Things

Netherlands: Wireless sensors useful in optimizing glashouse climate

During orientation research at tomato growers Gebr.Verbeek in Velden, the Netherlands (North Limburg province) it has become clear this spring that wireless sensors may well be used in optimizing the glasshouse climate. It is possible with this technology to use energy more efficiently. The research has been done by Wageningen UR Glastuinbouw together with AgriSensys and Climeco in the framework of the project Gezonde Kas.

In most glasshouse the climate is controlled by a measuring box and a climate computer. The traditional measuring box collects data about the relative humidity of the air and the temperature of each section of the glasshouse. This measuring is the establishment at a certain point and does nor show differences in climate in the glasshouse. When adjusting the temperature and the humidity the climate computer therefore applies a considerable safety margin. Often more heat is then produced than necessary.
Wireless network
Wageningen UR Glastuinbouw has developed a wireless sensor system, which in the meantime is available under trade name AgriSensys. The wireless sensor network consists of a number of measuring boxes and a basic station. The measuring boxes are in various spots in the glasshouse and the base station collects the information via a web-application and produces a graph.  The grower in this way knows the horizontal differences in climate and where and when there is a risk of wetness in the glasshouse.
This spring a test was carried out at Gebr.Verbeek. 25 sensors were positioned in the tomato glasshouse, which is equal to 10 sensors/HA. During the period February to May measurements of the measuring box were compared to those of the sensors.
During the test it became clear that based on the values of the measuring box it very often resulted in unnecessary heating of the glasshouse. Also the grower, because of the sensor network, became more aware of the critical points in the glasshouse.
Potplant test
From the research it is clear that a wireless sensor network is a good instrument to improve the climate in the glasshouse and to save energy. The research will be followed in the project Gezonde Kas at the testing station in Straelen. A test in a pot plant glasshouse will follow in September

The project Gezonde Kas is an INTERREG IV A program, in which border areas work on Europe. Research companies and business in the region Greenport Venlo and agro business region Nederrijn cooperate on practical solutions for glasshouse horticultural companies. More information here.
