Thanks for all your answers.

Lithium 9V batteries are sometimes 1200mAh. For example smoke detectors will run for many years on those. Corrosion can be easily avoided with pcb spray (I use SK10 flux spray).

The cheap 433MHz transmitter uses less than 1...

It's Open Source so you can always study the implementation.  Here it is with the code to enable and disable the specific interrupt removed:

Hex output has been added. The options are:

* ascii (as received from the serial port)

You can specify the number of hex characters to appear per line via a trackbar / text control.

3D Printshow announces events in London, Paris and New York #3DThursday #3DPrinting

3d printshow 2013

Last year's 3D Printshow in London (see video from the BBC below) such a success, its organizers are planning more 3D Printshow editions all across the world.

3D Printshow announces events in London, Paris and New York, via 3Ders.org:

Attendees could enjoy live demonstrations, workshops and seminars showcasing design, fashion, art, food, archaeology & Medical science. All products are produced using 3D printing.

For supporting the growth and education of young people across the UK, Europe and the USA, the 3D Printshow Education Session on Friday 7th November (London) and Friday 15th (Paris), NYC (dates tbc) features a lineup of interactive workshops developed specifically to engage and stimulate young minds.

This session will be free of charge to anyone that works in education and for any school or university bringing students to attend the show. 3D Printshow are also going to give every comprehensive school that brings more than thirty-five students a free 3D Printer to take back to their design department.

"The challenge is not just inspiring future generations, it's about giving them the tools to create and supporting their ability to learn." says 3D Printshow founder Kerry Hogarth.

3D-Printed Fashion Jacket Created With Blender and an Ultimaker 3D Printer #3DThursday #3DPrinting

Fashion jacket 3d printed 8 555x400

3D-Printed Fashion Jacket Created With Blender and an Ultimaker 3D Printer, via BlenderNation.

Art couture designer Larisa Katz and 3D designer Patrick Römgens used Blender and an Ultimaker 3D Printer to create a jacket. The work was featured on the Royal Ascot Ladies' Day this June 2013 in London.

Patrick writes:

For this project we've used a Rapman 3.2 Ultimate Kit and an Ultimaker Rev. 3. and lots of flexible and normal PLA filament. Both have been printing for almost 3 weeks non stop (seriously 24/7) to get this project done.

As the article on 3Ders.org mentions, we've started with taking a full body 3D scan of Larisa. This was done with Skanect 1.4 and a Carmine 1.09 from Primesense and gave amazing results. We than polished the scan and removed things we didn´t need from it and that´s where the Blender-'pleasure' started….

The freestyle working environment of Blender was really what this project needed, it would´ve been impossible to create this jacket on CAD programs or other not so advanced 3D modeling software, Blender was the only package that gave me the full mountain of tools to get this natural and organic looking jacket modeled.

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!

Legislating for Headlines Makes you Look Like a Jerk #3DThursday #3DPrinting

Posted: 27 Jun 2013 01:00 AM PDT

Pknowledge logo

Check out this piece from Michael Weinberg of Public Knowledge that points out, with humor and clear logic, that: "Introducing laws that regulate 3D printing before figuring out what 3D printing is will not lead to success."

Legislating for Headlines Makes you Look Like a Jerk, from Public Knowledge:

Occasionally, lawmakers are motivated more by their desire to get a headline than their desire to make good policy.  All of the attention that 3D printing has been getting lately makes it a tempting target for just that impulse.

There have already been a handful of bills at the local, state, and national level introduced with some connection to 3D printing and guns.  But a recent bill out of New York City stands out as a shining example of legislating for a headline without taking a moment to understand the substance.

Why is 3D Printing in this Bill?

The bill, introduced by New York City Council Members Lewis A. Fidler, Letitia James, Margaret Chin, Domenic M. Recchia, Jr., Leroy Comrie, Mark Weprin, Annabel Palma, Helen D. Foster, Gale A. Brewer, Maria Del Carmen Arroyo, Inez E. Dickens, Robert Jackson, Andy King, Peter A. Koo, G. Oliver Koppell, Brad S. Lander, Rosie Mendez, Deborah L. Rose, and Albert Vann is four pages long but you can stop at the beginning.  It starts by adding a new definition to the administrative code of the city of New York.  That definition is for "Three-dimensional printer":

"A computer-driven machine capable of producing a three-dimensional object from a digital model."

Why does this definition betray shameless headline chasing on behalf of Council Members Fidler, James, Chin, Recchia, Comrie, Weprin, Palma, Foster, Brewer, Del Carmen Arroyo, Dickens, Jackson, King, Koo, Koppell, Lander, Mendez, Rose, and Vann?  A 3D printer is "a computer-driven machine capable of producing a three-dimensional object from a digital model," isn't it?

Sure.  But so is every other modern manufacturing machine.  A CNC mill fits that definition.  As do laser cutters.  So do industrial arms that build cars on assembly lines.  And robots.  And, for that matter, automated crochet knitting machines….
