May 2011 meeting

Another awesome meeting with dc414 this month. dw5304 pwned us all with his GPS jammer, and a ardunio RFID reader. The laser mic from last months meeting was busted out for a while and ngharo brought his oscilloscope which we used to mess with the RFID reader. Vladimir had some killer lasers, one of which we used to light a cig 😀 Check out the vids below to see some of the fun 🙂

My lame IR copy toy.

I got a sweet arduino for my bday and it kind of just sat around till i got a few things together to start work on my first project. Well i finally got off my ass, got all the shit i needed and got to work! I am about half way done and i thought i would share my progress so far. heres a little video of my toy in action and i go over the operation and components.

Here is a better view of how its put together:

And here is my uber 1337 code 😛

#include < IRremote.h >

int IRRECV = 11;
int READYLED = 9;
int PLAYBUTTON = 5;
int IRLED = 3;
int RESETBUTTON = 7;
int PLAYLED = 2;
decode_results results;
IRrecv irrecv(IRRECV);
IRsend irsend;

void setup()
{
Serial.begin(9600);
irrecv.enableIRIn();
pinMode(READYLED, OUTPUT);
pinMode(PLAYBUTTON, INPUT);
pinMode(RESETBUTTON, INPUT);
pinMode(PLAYLED, OUTPUT);
}
int codeType = -1;
unsigned int rawCodes[RAWBUF];
int codeLen;
void rec(decode_results *results)
{
int count = results->rawlen;
codeLen = results->rawlen - 1;
for (int i = 1; i <= codeLen; i++) { if (i % 2) { rawCodes[i - 1] = results->rawbuf[i]*USECPERTICK - MARK_EXCESS;
Serial.print(" m");
}
else {
rawCodes[i - 1] = results->rawbuf[i]*USECPERTICK + MARK_EXCESS;
Serial.print(" s");
}
Serial.print(rawCodes[i - 1], DEC);
}
Serial.println("");
digitalWrite(READYLED, HIGH);
}

void play()
{
digitalWrite(PLAYLED, HIGH);
Serial.println(rawCodes[0]);
irsend.sendRaw(rawCodes, codeLen, 38);
delay(800);
digitalWrite(PLAYLED, LOW);
}

void reset()
{
int codeType = -1;
unsigned int rawCodes[RAWBUF];
int codeLen;
digitalWrite(READYLED, LOW);
setup();
}

void loop()
{
if (irrecv.decode(&results) && digitalRead(READYLED) == LOW) {
rec(&results);
irrecv.resume();
}
if (digitalRead(PLAYBUTTON) == LOW && digitalRead(READYLED) == HIGH)
{
play();
}
if (digitalRead(RESETBUTTON) == LOW)
{
reset();
}
}

Ok thats all i got, peace.
