Pachube service goes free! via Shigeru – [via]
We’re making the Pachube service free for all users. As of today there will only be one type of account. Every user will have unlimited datastreams, datapoint uploads and history as well as the option to create private feeds. We are setting a limit on the API request rate at 100 requests/minute. Current PRO users will see their rate limit go up from 40/minute to 100/minute. Current PREMIUM users will keep their current rate limit of 250 requests/minute.
…So, why go free? No, we haven’t decided to become a non-profit. No, we’re not just super-nice. What we are is ambitious. And having worked with and talked with many people in the Pachube community, we know that they’re ambitious too.
The “Internet of Things” is a big idea (though secretly many of us don’t actually like that term), and we want our community to lead the effort to define it. As devices continue to find their way onto the Internet, we want them to be able to take advantage of everything the Web has to offer. We want Pachube users to control their own data, build applications that we would never envision, and share with others as they see fit. This idea, as obviously correct as it sounds to us, is not inevitable. There are significant business and technical barriers to this vision.
By making the Pachube service free, we’re removing a small barrier today, and we’re committed to removing more barriers in the coming months. The Pachube service is not as easy to use as we want it to be. It still doesn’t do everything we want it to do. This is, of course, okay. That’s why our engineers come to work every day, sit at too-small IKEA desks and code their asses off. Pachube will continue to get simpler, better and more capable. Our intention is that many of these new capabilities will be free. Some of them won’t. We hope that you’ll want to pay for the stuff we decide to charge for.

element14 today unveiled The Drawer, an innovative new content storage tool for design engineers that allows users to capture, collect and store information, parts and content as they navigate through the element14 community and the knode.
A recent TFI Global Study revealed several pain points that engineers face during the design process—increasing time pressures, incomplete/inaccurate information from relevant sources, and difficulty comparing options. And, the Drawer addresses many of these needs, giving engineers an easy way to store and compare relevant news, videos and product information from across the entire element14 community. A video of The Drawer in action is available here.
The full press release is below. I believe this story would be of real interest to your readers and I’d be happy to arrange a discussion with Jeff Jussel, senior director of global technology marketing at element14, to discuss The Drawer and other design solutions, and their impact on the industry.

“A Day in the Life of an Engineer”
element14 invites electronics designers to share their ingenuity and inspire peers
October 18, 2011 – London, element14, Premier Farnell’s innovative online engineering community, announces the launch of “A Day in the Life of an Engineer”, an online video challenge, open to electronics design engineers and enthusiasts worldwide until January 31, 2012.
“At element14, electronics innovation is at the core of our business by bringing everything together for the designer in one site, from solutions and services, to components and a collaborative engineering community of experts, peers and a wide range of technical information,” said Dianne Kibbey, Global Head of Community and eProcurement, Premier Farnell.
“Anyone in the electronics field faces a daunting task today with the ever increasing pressure to do everything faster and better. As we’ve seen time and again, electronics innovation can happen in someone’s garage, a lab, at the office or in a classroom – but it is all about the creativity that can happen in this wide-ranging field. This competition gives us an opportunity to better understand those challenges and to showcase how electronic designers find innovative solutions to everyday problems, or even pose their own challenge on what they think needs to be solved in the future.”
Entrants are invited to “tell their story” by submitting a video blog to element14.com/videochallenge. The choice of topic can be anything from a video blog about a designer’s workbench, to highlighting how a problem was solved or just taking a camera into work and talking about daily challenges around the office. It can even be about what people think the next big innovation needs to be in the electronics industry.
The videos will be judged on their creativity by a panel of element14 peers and the winner will receive an iPad2. In addition, one winner will be randomly selected each week to receive a selection of element14 branded merchandise from that week’s entrants, which include those who comment, vote or post videos.
Challenge details and examples of video entries can be seen at element14.com/videochallenge

If you want to host an open source hardware project today, you have to cobble together wikis, forums, online polls, blogs, and online file storage to share your materials. Then you have to send the link (or links) to your “system” to the people you already know who might be interested in participating. For a person who just wants to start designing and building cool stuff all that pre-work is a giant pain in the you-know-what.
So is it any wonder that most makers interested in open sourcing their designs tend to skip that step, do all the work themselves and then just release the final designs on the web when they get around to it?
There has to be a better way.
In order for open source hardware to become as prevelant and infulential in the hardware community as FOSS is in the software community we need a way to integrate the required services into a single system, as well as provide a destination for users looking for open source hardware projects to build or to extend to get involved in the community.
Enter Open Design Engine.
If it takes a forge to develop open source software, then you need an engine to develop open source hardware. Introducing Open Design Engine (ODE). ODE is a web based engineering project management system created to facilitate the design and development of openly licensed hardware projects. ODE provides a critical service to the growing open source hardware community, similar to the role Source Forge played in the early growth of open source software.
ODE is based on the open source software Redmine and is licensed under the GNU General Public License v2 (GPL). ODE is being distributed in a similar manner to WordPress. Which means there will be a version available for download that users can install on their own servers (like http://wordpress.org) and a hosted version where users can register accounts and host projects (like http://wordpress.com).
Version 0.1 of the site is up and running at https://opendesignengine.net, but before user accounts can be made available to the public, V0.2 must be completed.

The radio mobile network is made up of a number of adjacent radio cells, each of which is characterized by an identifier consisting of four data: a progressive number (Cell ID), a code related to the area in which that given cell is (LAC, or Local Area Code), the code of national network to which the cell belongs (MCC, an acronym for Mobile Country Code), and finally the company code (MNC, or Mobile Network Code), which obviously identifies the phone company itself. For this reason, once a cell name and coordinates are known, and considering the maximum distance allowed between this cell and a phone before the phone connects to a new cell, it is possible to find out, approximately, the most distant position of the phone itself. To explain how the systems works, we made this page. You have to insert the data of the GSM cells and then the PHP page gives you the position and the range.
