on saturday the 2.May i was invited as a speaker to the second Osliper Computer-Workshop-Day. This time the workshop was about processing and arduino. read the summary by Franz on his blog (in German), to see some of the examples we made.

like the first OCWD (which was about python, django and pylons) it was really a whole lot of fun, and i'm looking forward to the next ones

Two Minute Timer in mobile.processing

Nikolaus Gradwohl2009-04-26T09:50:00+00:00

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

install twominute timer

you can also use the direct link (but i think it is a bit complicated to enter on a mobile phone)

processing bubbles

Nikolaus Gradwohl2009-04-13T21:44:00+00:00

here comes another completly useless processing sketch by me this time starring bubbles

ok, it's not that useless i changed the transparency of the bubbles according to the speed so slower bubbles seem to be more distant from the viewer than faster ones.

this generates a nice and simple parallax effect.

Digital Caleidoscop

Nikolaus Gradwohl2009-04-09T05:58:00+00:00

i made a digital caleidoscop using processing sketch click here to see it in action. I had to use openGL for this sketch so i'm not sure if it works as an applet on all plattforms. Download the code and run it as an app if the applet doesn't show anything.
