Two Minute Timer in mobile.processing

2009-04-26T09:50:00+02:00

no system or programming language should be without it's 2 minute timer for all those GTD followers out there. so i made one in mobile.processing.

the programm starts a 120 sec countdown and sends the app in background. After 2 minutes the vibration alarm is activated for 1 second.

i made a qr-barcode that contains the link to the jad file. just point a qrcode reader like zxing to it and install it

you can also use the direct link http://www.local-guru.net/mobileprocessing/twominutetimer/midlet/twominutetimer.jad (but i think it is a bit complicated to enter on a mobile phone)

qr-code midlet installer

2009-01-25T14:26:00+01:00

to simplify the installation of my mobileprocessing-sketch i have generated a qrcode-tag that downloads the jad file and installs the midlet on the mobile phone.

simply point a qrcode reader like the one from zxing to the image and click on download

Random numbers with MobileProcessing

2009-01-25T08:14:00+01:00

I wrote my first sketch in MobileProcessing. MobileProcessing is a processing dialect, that can be used to write apps for java-capable mobile phones.

The application can be used to generate random numbers. every key-event shows a new random number.

PFont font;
int rnd = 0;

void setup() {  
  font = loadFont( FACE_PROPORTIONAL, STYLE_PLAIN, SIZE_LARGE );
  textFont( font );
  textAlign( CENTER );
  fill(0);
  rnd = random(0,100000);
  noLoop();
}

void draw() {
  background(255);
  text( "\n\n\n"+rnd, 0, 0, width, height );
}

void keyPressed() {
  rnd = random(0,100000);
  redraw();
}
