Re: Storing Characters in EEPROM

Posted: 18 Apr 2013 03:02 AM PDT

Just to make it clear, EEPROM.write() takes an address (where to write) and a byte (the value to write). Now, fortunately for you, bytes and chars are exactly the same size, so you can use EEPROM.write() to write a char, without having to resort to spl...

Epilog Laser Announces Fifth Annual Epilog Challenge Hosted on Instructables.

Golden, Colo. (April 15, 2013) Epilog Laser is excited to announce the Epilog Challenge contest is back for round five, and will be hosted on Instructables.com. "Epilog Challenge V" opens today and runs through July 15, 2013. The lucky grand prize winner will receive a 30-watt Zing 16 Laser from Epilog.

"We've always appreciated the tremendous support we've received from the DIY community, and no matter who wins this challenge I have no doubt that he or she will make great use of the Zing 16," said Mike Dean, vice president of sales and marketing for Epilog Laser. "We're excited to partner with the folks at Instructables.com once again and anticipate seeing some very unique and creative entries."

"I'm always amazed by the fantastic projects the Epilog Challenge inspires," said Eric Wilhelm, founder of Instructables.com and director of communities at Autodesk. "I hope to see even more mind-blowing projects this year!"

Previous Epilog Challenge winners include the DIY High-Speed Book Scanner, the 8x8x8 Animated LED Cube, Arduino Powered Chess Playing Robot, and most recently, Build a Laser 3D Printer – Stereolithography at Home.

Hej
Hedder det også Sous-Vide, når man opvarmer noget i micro'en ?

Til at måle temperatur kan du bruge en DS18B20 (digital) eller LM35 (analog)
Jeg tror de begge fås i vandtætte udgaver, ellers kan du putte dem i et lille rør, som ...

How about good, old fashioned

but as you are reading a character before you know there is anything to read, and will get only one character anyway, you need to restructure your code.

EFF and Partners Challenge Six 3D Printing Patent Applications #3dthursday

Posted: 18 Apr 2013 02:00 AM PDT

EFF and Partners Challenge Six 3D Printing Patent Applications. (Or check the amusing write up about this announcement on The Verge.)

If there's something that drives us crazy, it's when patents get in the way of innovation. Unfortunately, we often don't find out about the most dangerous patents until it's too late—once they've been used to assert infringement. That's why we were encouraged by the new provision of the patent law that allows third parties to easily challenge patent applications while those applications are still pending.

But, here's the rub: it's hard to identify those dangerous applications. And, once you do, it's even harder to find the right information to challenge those applications during the window that the law allows. So we partnered with the Cyberlaw Clinic at Harvard's Berkman Center for Internet and Society and Ask Patents and—most importantly—you.

As of today, we've now challenged six pending patent applications that you helped us identify as applications that, if granted, would particularly threaten the growing field of 3D printing technology. Harvard's Cyberlaw Clinic hand delivered the first two submissions to the Patent Office earlier this year, and we've since sent in four more.

The prior art we've submitted so far thanks to your submissions ranges from patents and blog posts to research papers and symposium proceedings. Each prior art document gives the Patent Office tools to reject patent claims for obviousness. That in turn helps protect the diverse, exciting uses of 3D printing that are gaining in popularity each day, from small hobbyist printers to large-scale, high-quality commercial fabrication using materials ranging from titanium to chocolate.

Here are copies of what we submitted to the Patent Office. The good news is that so far, the Patent Office has accepted our submissions (because of that, if you're thinking of making your own preissuance submissions, you might want to use these as a model). Now we wait to see whether our input influences the examiners…..

Check out their first six submissions here!

And, just because I couldn't resist, here is a piece of the write up about this annoucement from The Verge:

Since Julie Samuels joined the EFF as the Mark Cuban Chair to Eliminate Stupid Patents, she's spearheaded the movement to keep 3D printing free by challenging new applications with crowdsourced prior art. Today, the EFF is announcing that it and its partners including Harvard's Cyberlaw Clinic and Ask Patents have now submitted documents on six pending applications, including one for a "Ribbon Filament and Assembly for Use in Extrusion-based Digital Manufacturing Systems" — i.e., using a filament that's fettucine-shaped instead of spaghetti-shaped because it melts more quickly.

It's the same information, but…with more humor.

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!

Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don't forget the countless LED projects that are possible when you are modeling your projects in 3D!

The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you've made a cool project that combines 3D printing and electronics, be sure to let us know, and we'll feature it here!
