The Work of Josh Nimoy – TRON special effects Posted: 28 Jan 2013 02:00 AM PST The Work of Josh Nimoy. I spent a half year writing software art to generate special effects for Tron Legacy, working at Digital Domain with Bradley "GMUNK" Munkowitz, Jake Sargeant, and David "dlew" Lewandowski. This page has taken a long time to be published because I've had to await clearance. A lot of my team's work was done using Adobe software and Cinema 4D. The rest of it got written in C++ using OpenFrameworks and wxWidgets, the way I've always done it with this team Uniquely however, Digital Domain's CG artists were able to port my apps over to Houdini for further evolution and better rendering than OpenGL could ever provide. Special thanks to Andy King for showing me that what seasoned CG artists do at DD is actually not so far off from what's going on in the Processing community. Read more.

compiler optimization or bugs ? you have to know how gcc behaves Posted: 28 Jan 2013 01:51 AM PST Hi There, after spending some time on trouble shooting a piece of code this week end (...), I decided to share my experience on the forum regarding how the hell our gcc compiler is generating some different code depending on its optimization mechanism ...

Re: Problemas con potencia servo 17kg Posted: 28 Jan 2013 01:44 AM PST Mi solución final en estos Post, http://rcarduino.blogspot.com.es/2012/04/servo-problems-with-arduino-part-1.html?m=1 http://rcarduino.blogspot.com.es/2012/04/servo-problems-part-2-demonstration.html?m=1 Gracias a todos por vuestra ayuda

Measuring Small Currents (<= 100mA) Posted: 28 Jan 2013 01:42 AM PST I've decided to try measuring the current consumption of a battery powered gadget.  The measured current is always less then 100mA.  The voltage varies between 3.1 V and 1.8 V.  I'm currently using an Uno to measure the voltage and I want to also meas...

Re: float Deviation Posted: 28 Jan 2013 01:37 AM PST Das ist fisologisch bei Fließkommazahlen. Sie können zwar einen sehr großen Bereich an Werten abdecken (3.4028235E+38 bis -3.4028235E+38) aber haben nur eine Genauigkeit von 6 bis 7 Ziffern. Daher kommen diese Rundungsfehler. Die Lösung hat Mekanax  be...

Re: Problem writing to SD card Posted: 28 Jan 2013 01:36 AM PST OK, that seems to work better now. I didn't know that a comma worked in that way. Thanks.

Re: [Ethernet-Shield] Nach neustart des Arduino geht nichts mehr Posted: 28 Jan 2013 01:14 AM PST Hallo! Danke für die zahlreichen Tips! Nein, Kommando zurück, es lag an dem überfüllten RAM des Arduino !! Gruß Chris

Re: atmega1284 programming from a 328 chip Posted: 28 Jan 2013 01:13 AM PST Thanks for the replies. I too have no idea what is happening.  When the 328P is breadboarded, with DTR connected to  the reset via a 0.1uF capacitor in series and a 10K pull up resistor I can select the Uno as the board in the IDE and it uploads many o...

Re: DHT 22 Example in Arduino 1.0.3 not working Posted: 28 Jan 2013 01:11 AM PST It works great! Thanks for your help!

Re: LED board Sure electronics Posted: 28 Jan 2013 01:09 AM PST Quote from: Andre_27 on January 27, 2013, 06:00:00 PM Mmmmm mi sa che dovevo dire in serie  O comunque 2 o più batterie da 9v in parallelo, giusto? Se metti 2 batt da 9V in parallelo raddoppi la corrente e di conse...

Re: decoder encoder telecomando IR [risolto] Posted: 28 Jan 2013 01:09 AM PST Infatti il progetto è buono e farebbe al caso mio, tra l'altro a livello hardware ho già tutto, attiny compreso, ma adattare le mie esigenze al software è abbastanza arduo, perché le codifiche che usano le mie periferiche sono diverse da quelle propost...

World’s oldest portrait Posted: 28 Jan 2013 01:00 AM PST World's oldest portrait reveals the ice-age mind via Bruce. Twenty-six thousand years ago in the Czech Republic, one of our ice-age ancestors selected a hunk of mammoth ivory and carved this enigmatic portrait of a woman – the oldest ever found. By looking at artefacts like this as works of art, rather than archaeological finds, a new exhibition at the British Museum in London hopes to help us see them and their creators with new eyes. Human ancestors date back millions of years, but the earliest evidence of the human mind producing symbolic imagery as a form of creative expression cannot be much older than 100,000 years. That evidence comes from Africa: this exhibition explores the later dawning of representative art in Europe and shows that even before the remarkable paintings of the Lascaux cave, France, humans were able to make work as subtle as the expressive face above. What will people 26,000 years from now think about the portraits we are making now? Read more.

Re: TFT 3.2 Touch Arduino MEGA Ghost Lines!!! Posted: 28 Jan 2013 12:54 AM PST yeah,i think so, this looks like a bad display, ask sainsmart for a replacement, thanks for your sharing

Re: Small power source for one century Posted: 28 Jan 2013 12:54 AM PST Set up a temple around it with a bunch of monks to care for it and organize a suitable ceremony when it opens.

Market Sow Zaragoza Posted: 28 Jan 2013 12:52 AM PST Los dias 22-23-24 de febrero se celebra un encuentro sobre impresion digital, arduinos, open hardware, etc http://www.arduteka.com/2013/01/etopia-maker-show-zaragoza/ Yo tengo la intencion de ir , soy de Alicante , y querria saber si hay alguien de mi ...

Re: NilRTOS - A Fast Tiny Preemptive RTOS Posted: 28 Jan 2013 12:49 AM PST Works nice!   (ie. Uno, 5 adc channels, 2048usec period, cheap card, 7 minutes logging time, 5.5MB data.csv): [code]type any character to begin type any character to end Done FIFO record count: 75 Minimum free record count: 54 Maximum SD write latenc...

float Deviation Posted: 28 Jan 2013 12:48 AM PST Hallo zusammen, kann jemand diese Abweichung erklären? Das Programm soll Zahlen von 0 bis 10 in Schritten von 0,1 ausgeben, Das Ergebnis ist jedoch so: Die Schleife durchläuft den Wert 10 garnicht! (ich verwende Micro und UNO R3) Programm: void ...

Re: Still having problems with switch case menu... Posted: 28 Jan 2013 12:20 AM PST Where in the code are you reading the pins to get the values of upSwitchState, downSwitchState and okSwitchState ?

Re: Energie alternative Posted: 28 Jan 2013 12:20 AM PST Metti una ROM modificata, la vera. 4.2.1 è eccezionale

Re: FET recommendation Posted: 28 Jan 2013 12:19 AM PST IRL540s are inexpensive, but will have a larger Rds(on) than the newer, more expensive parts. Shouldn't matter, if the currents aren't too high. Using a small value R in the gate ckt is usually a good idea. Helps isolate the uC I/O pin from the largi...
