I decided to add an Ethernet connection to my current project. The Ethernet shield from NKC Electronics is build around the WIZ812MJ module which provides an hardware implementation of a TCP/IP stack. I had one flying around but since I used an Arduino Pro with special headers and will probably add a case the stackable shield was not an option.
So we (me and BRave) soldered a simple power supply and ICSP header to hook everything up.

Eventually strange creations showed up randomly at the desk ...
Or, more likely, it was just solder fumes.

I spend the last few days at the 26C3. It was sold out pretty quick on the first day.

Bei der Abschlusskundgebung sprach Frank Rieger vom Chaos Computer Club (CCC), der die viertägige Hackerkonferenz ausrichtet, zunächst von einem neuen Teilnehmerrekord mit über 9000 Leuten. Die Zahl lässt sich aber nicht mit dem Vorjahr vergleichen, in dem 4230 Tickets ausgegeben wurden: Für dieses Jahr hatte Rieger die Besucher der weltweit rund 30 Kongressableger mit Streaming-Versorgung mit einbezogen.

A friend mentioned that if the congress will get any bigger, it would be needed to build a complete new congress center.
I think the trend of satellite events like streaming at c-base and C4 Lab streamings will grow and the whole event may become more decentralised.

It was amazing to meet a lot of interesting people and building interesting stuff.
Like the LoL Shield designed by Jimmie.
So far for now. I'm heading for a cold shower and than the CCCB ... hope there's space for my friends and me to tinker around with the LoL Shield.

Yesterday I went to the "Bastelabend" at the C4 Labs in Cologne. There were a lot of interesting projects and someone mentioned that you can use LEDs as sensors when you change the potential.

For more information follow this link.

I hooked up my arduino and ripped some code together.

int LED_anode[] = {2,4,6};
int LED_cathode[] = {3,5,7};
int LED_max[] = {0,0,0};
int LED_min[] = {0,0,0};

int t_delay = 1000;

int value;

void setup()
{

//deactivates pullup
_SFR_IO8(0x35) |= 4;
_SFR_IO8(0x35) |= (1<<4);

for( int i=0; i <= 2 ; i++ )
{

pinMode(LED_anode[i],   OUTPUT);
pinMode(LED_cathode[i], OUTPUT);

}

Serial.begin(9600);

Serial.println("Calibration");

for( int i=0; i <= 2 ; i++ )
{

Serial.println("MAX LED ");
Serial.print(i);
delay(t_delay);
LED_max[i] = LEDget(i);
delay(t_delay);

}

for( int i=0; i <= 2 ; i++ )
{

Serial.println("MIN LED ");
Serial.print(i);
delay(t_delay);
LED_min[i] = LEDget(i);
delay(t_delay);

}

}

void loop()
{
value = 0;

for( int i=0; i <= 2 ; i++ )
{

Serial.print(i);
Serial.print(": ");
Serial.println(map( LEDget(i), LED_min[i], LED_max[i], 0, 255 ), DEC);

}
}

int LEDget(int i)
{

int value = 0;

digitalWrite(LED_anode[i],   HIGH);
digitalWrite(LED_cathode[i], LOW);   

digitalWrite(LED_anode[i],   LOW);
digitalWrite(LED_cathode[i], HIGH);

pinMode(LED_cathode[i],  INPUT);

while(digitalRead(LED_cathode[i]) != 0)
value++;
pinMode(LED_cathode[i],  OUTPUT);

digitalWrite(LED_anode[i],   HIGH);
digitalWrite(LED_cathode[i], LOW);

return value;

}

There is a calibration cycle at the beginning. When measuring the minimum value the LEDs should be completely covered.
Since the LEDs go thruogh the same cycle when calibrating as when in use the measured values shouldn't be affected by the LEDs themselves.

Sehr geehrte Leserschafft und Autoren ; )

ich bin Philip Stillke, studiere Architektur und interessiere mich wie viele hier allgemein für Kunst.

Meine Idee ist es, neben natürlich Architektur und Kunst, besonders lokalen Künstlern und Happenings an dieser stelle meine Aufmerksamkeit zu schenken.

hier noch passend zu meinem vorrangegangenen Beitrag ein interessantes Beispiel für "Verfremdung"

The relationship between science fiction and architecture

It is indisputable that architecture and science fiction are interconnected and that a process exist where both feed off from one another.

I have been always fascinated by science fiction threw all kinds, but my favourites always where those about future such as star trek and star wars

( even though it suppose do be a long time ago ; ).

Last semester I realized that there is a big connection between science fiction and architecture and became very excited. Since that point i use to design and create buildings like I use to build Lego spaceships as a young boy. When I watch a science fiction movie these days and see the landscape of a city, I instantly try to find similarities in style from things we know from reality.

Coruscant for example: is a planet in the star wars universe, whose surface consists of one big multilevel megalopolis. George Lucas calls him self a “Victorian” type and so this future mega city ended up having an “art deco” kind of style. The skyscrapers, so tall that you can hardly figure out where they start, do remind us on buildings such as the Chrysler Building in New York, one of the art deco icons.
