How to make the file name being dynamic for my project? Posted: 28 Mar 2013 03:01 AM PDT Now i created a camera project with button, while i click the button the project will save a .jpg file inside SD card for me. I use the example from my JPEGCAMERA library, it worked, so the problem for now is i cannot let my project save the .jpeg file...

Re: Project 04 Posted: 28 Mar 2013 03:00 AM PDT I have the same issues.

27 Science Fictions That Became Science Facts In 2012 #3dthursday Posted: 28 Mar 2013 03:00 AM PDT We received a link to this fun collection of "science facts" for 2012 and want to share them. Two of them were really fun 3D printing details, so we are highlighting these two today — but take a look at the entire list over at MyScienceAcademy. (And, yeah, we totally on them about the Voyager I claim as well. So you don't have to wag a finger at us!) 9. 3-D PRINTER CREATES FULL-SIZE HOUSES IN ONE SESSION The D-Shape printer, created by Enrico Dini, is capable of printing a two-story building, complete with rooms, stairs, pipes, and partitions. Using nothing but sand and an inorganic binding compound, the resulting material has the same durability as reinforced concrete with the look of marble. The building process takes approximately a fourth of the time as traditional buildings, as long as it sticks to rounded structures, and can be built without specialist knowledge or skill sets.

The first of its kind, the successful surgery opens the door for individualized bone replacement and, perhaps one day, the ability to print out new muscles and organs.

Re: far cantare ad arduino jingle bells Posted: 28 Mar 2013 02:59 AM PDT "cantare"? Che intendi per "cantare"? Vuoi far riprodurre un file musicale MP3? Ci sono degli shield appositi. Vuoi far riprodurre un "motivo" musicale? Allora c'è la Tone. Oppure il sistema detto da jumpjack: http://www.arduino.cc/en/Tutorial/Melody h...

Re: OT colla per led 1w / dissipatore Posted: 28 Mar 2013 02:25 AM PDT Ho fatto qualche ricerca, che ne pensate di questi, com'è secondo voi il primo della lista?

Re: coding/algorithm interpreting sensors. where to start? Posted: 28 Mar 2013 02:25 AM PDT Yes that looks fine although I normally put each compair in brackets. You can also use || for ORing conditions.

Simply internet checking with Ethernet shield Posted: 28 Mar 2013 02:24 AM PDT Hi to everyone! I write to you becouse i need to understand something about ethrnet shield. I decided to made up a simply sketch that check the internet status every n minutes but honestly i don't want to ping a server or make a get request (like i can...

Re: Mesure de produit inflammable Posted: 28 Mar 2013 02:24 AM PDT je viens peut être de trouver une piste http://www.instrumexpert.com/ShowPost.aspx?PostID=380 autre piste sur le même site pour mesurer du ciment ou platre http://www.instrumexpert.com/ShowPost.aspx?PostID=2466

Re: Optocoupler-based volume control controlled with rotary encoder Posted: 28 Mar 2013 01:59 AM PDT Bit of a convoluted way of doing it... Personally I'd have a separate "muted" variable, and not manipulate the volume variable at all. [code] VolumeChanged := false If button pressed   Muted := not Muted   VolumeChanged := true End If If turned clockwi...

Goldeneye 007 Remote Mine by ComradeQuiche #3dthursday Posted: 28 Mar 2013 02:00 AM PDT Not only a very cool print with integrated electronics components, but also a good litmus test to tell what you were doing in the late 90s. Created by ComradQuiche, shared as Thingiverse Thing 54528: A printable Remote Mine prop with blinking lights, a beeper, and a magnetic back! If you grew up in the 90′s, you've played Goldeneye, and if you've played Goldeneye you should recognize this classic weapon! After creating a tutorial on Instructables on how to make a Remote Mine using an old joystick base, I decided that I would model one up so others could print their own. The problem with my Instructables is it requires you to find a "PC Commander" Joystick from the 90′s to use as the Remote Mine's body. It took me about a month to track one down, and they get more rare every year. So now that this ancient component is nearly extinct I wanted to make sure everyone could still make their own remote mine prop. With a few components and some patience you too can make your very own remote mine prop, chock full of blinking lights and beeping sounds! Read more. 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!

Re: So I've burnt my 3.3v output... Posted: 28 Mar 2013 01:41 AM PDT Quote No on the "voltage divider" idea. Why? I had that setup running for weeks without problems.... Many chinese SD card slots for arduino on ebay "want" you to use 5V, surely thats stupid and might damage the sd card. But using a voltage div...
