Jeff Keyzer, a/k/a MightyOhm, has created an awesome new group on Flickr called “Electronics Workbench”. He writes: [via]

Ahh, the electronics workbench – shrine to the electron, the diode, the transistor, the soldering pencil and flux pen.

You can learn a lot about someone by looking at their workspace. Note the way that they store components (in pullout drawers or plastic organizers?), hang test leads (on hooks or wire racks, or on a nail?), and keep spools of wire at the ready for repairs and new projects.

A look at someone’e electronics workbench gives you a small glimpse into what is usually a fairly personal space – a space where visions become reality and electronics projects are brought to life.

While there are quite a few electronics workbenches on flickr, I determined after a quick search that there had been no attempt to bring all of these glimpses into a hobbyist or engineer’s soul together into one place.

It’s open to everyone, so if you’ve got photos of your own bench, add it to the group!

Tinkercad – Design physical things in your browser – [via]

Have your first 3D project ready for printing in minutes. Tinkercad is a new and faster way of creating designs for your 3D printer. With the help of the latest web technology you can now use a solid modeling CAD directly in your browser.

The user interface is designed to get things done fast and to be quick to learn. With only three basic tools you can create a wide range of useful things. Once your project is ready simply download the STL file and start your 3D print.

Global online community element14 has been very busy lately implementing innovative new ways to help engineers stay one-step ahead—from dedicated hubs to aid communications in Thailand to development kits designed to help engineers bring products to market faster than ever before. Following are a few noteworthy additions to the element14 community:

  • The SAM9 development kit is now available on the community—a full-featured evaluation board centered on Atmel’s ARM based AT91SAM9G45 processor, designed to provide developers with a feature-rich, development platform for ARM926 based embedded microprocessor design enabling shorter development cycles and significantly reducing time-to-market.
  • To support communications while companies navigate the flooding crisis in Thailand, element14 has created a dedicated online space at Thailand Flooding which will act as a central repository for the electronics industry on the rapidly changing situation.

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.

Here’s a (hopefully) complete list of entries in the Open 7400 Competition – Winners to be announced tomorrow – [via]

27 Oct 2011

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.
