using Buzzer with Processing

Nikolaus Gradwohl2009-09-06T18:34:00+00:00

I have written a processing sketch that shows how to use the buzzer for the ps2. the sketch uses the proCONTROLL library and draws a rectangle for every button on the buzzer.

Moving 3D Boxes in Processing

Nikolaus Gradwohl2009-09-05T13:36:00+00:00

this processing sketch draws some random 3d boxes using the P3D renderer. I really like the distorting artifacts that are generated by the smoothing. I made some manga style random lines around the boxes to intensify the effect

I just made another completely useless sketch in processing.

My name is

Nikolaus Gradwohl2009-09-02T16:44:00+00:00

Varvara Guljajeva is using my processing tts library for her lates project My name is

My name is - is a metaphorical visualization of nowadays-human beings. In my point of view we are not bounded to one body anymore. We are extended through networks to infinity. The location does not matter, what matters is connection. Thus, at this point I totally agree with Mitchell “disconnection would be amputation. I link therefore, I am.” We are becoming gradually fully equipped and totally dependent on technology cyberorgs.

The installation consists of 4 dolls in each a speaker inside, 4 relays, arduino, a computer, and a modem. We are using Processing, TTS (text to speech), and Arduino. The independent and at the same time isolated network is created. IP addresses are continuously renewed and sent to a random doll. Thus only one doll is speaking at a time (4 speakers are controlled by 4 relays through arduino).

the installation looks really cool - a bit creepy what she did to the dolls :-)

I just made another simple clock in processing. this time its a bit easyer to read than my last one :-)

Arduino based Office-WTF-Counter

Nikolaus Gradwohl2009-07-03T08:37:00+00:00

As in any office, my co-workers and I experience several WTF-Situations during our working day. So we decided to implement a simple system to count the WTF's and use them as a metric for our working climate :-)

we use an "emergency stop"-Button which is connected to an arduino. This arduino sends the string "WTF" on the serial line a little python scrip writes them to a file, another processing app count's the lines in the file and offers the result via http, which is read by a processing app for visualisation ...

QR-Code Carpet

Nikolaus Gradwohl2009-06-29T19:12:00+00:00

My Mother is always searching for cool motives she can use for her carpets. So i made a generated a qr-code containing her name which she weaved into a QRCode-Carpet


and the coolest part is IT ACTUALLY WORKS!!!

i made a processing sketch that decodes the image (click here to try it yourself)

and i also decoded it using my G1

processing tutorial

Nikolaus Gradwohl2009-06-19T02:02:00+00:00

I started to write a little processing tutorial, showing how to write a great sidescrolling space shooter like in this screenshot below.

please give me a little bit of feedback and show me all the great games you make with the help of my tutorial

colorclock in processing

Nikolaus Gradwohl2009-06-01T08:56:00+00:00

I made a processing-sketch that shows the time using colors. i made 3 stripes of colors blending into each other, each of them cycling through the hue value of the color. then i blend between the colors.

the top color shows the hour, the middle color shows the minutes and the low color the seconds. the values start at red, blend to yellow and green, and get turcise at the half of the cycle. than they blend to blue and violet and finally back to red.
