odd; it just screamed “i just learned how to use CGI”.

good times

Of all the weird things Venn comes up with for LGC, B-Reel is the only one I never understood. Is it a reference to Cypress Hill?

Then again, who dosn’t know how to use a 555 timer by now?

[strider]

Exactly. Now if you need a ne555 you just use a raspberry pi

[linuxgnuru]

in fact; I made this 6 sided die rolling gadget using this schematic

and here’s the end result:

I used the schematic from http://555-timer-circuits.uk/projects/dice.html

Looks like something that will definitely get me arrested

How did you manage to do this without a RaspberryPi? Are you a wizard?

You have to remember, he was doing RaspberryPi’s from scratch before there was even a RaspberryPi, also he’s one of them old people

damn you guys; I went ahead and wrote this quick C program that turns a raspberry pi into a 6 sided die…

Code:

#include <stdio.h>
#include <stdlib.h>
#include <strings.h>
#include <unistd.h>
#include <errno.h>
#include <signal.h>

#include <time.h> // for srand

#include <wiringPi.h>

#define MAX_NUM 7
#define MAX_DIG 6

/*
0 4
1 3 5
2 6
*/
const int pins[7] = { 0, 1, 2, 3, 4, 5, 6 };

const int pips[6][7] = {
{ 0, 0, 0, 1, 0, 0, 0 }, // 1
{ 1, 0, 0, 0, 0, 0, 1 }, // 2
{ 1, 0, 0, 1, 0, 0, 1 }, // 3
{ 1, 0, 1, 0, 1, 0, 1 }, // 4
{ 1, 0, 1, 1, 1, 0, 1 }, // 5
{ 1, 1, 1, 0, 1, 1, 1 } // 6
};

const int inputPin = 7;
const int haltPin = 29;

static void die(int sig);
void roll_die();

int main(int argc, char **argv)
{
int i;
int dl = 0;

srand((unsigned)time(NULL));
// note: we’re assuming BSD-style reliable signals here
(void)signal(SIGINT, die);
(void)signal(SIGHUP, die);
if (wiringPiSetup () == -1)
{
(void)fprintf(stderr, “oops %dn”, errno);
return 1;
}
for (i = 0; i < MAX_NUM; i++)
{
pinMode(pins[i], OUTPUT);
digitalWrite(pins[i], LOW);
}
pinMode(inputPin, INPUT);
pullUpDnControl(inputPin, PUD_UP);
pinMode(haltPin, INPUT);
pullUpDnControl(haltPin, PUD_UP);
/*
for (i = 0; i < 6; i++)
{
printDie(i);
delay(500);
}
*/
while (1)
{
if (digitalRead(haltPin) == LOW)
{
system(“shutdown -h now”);
}
if (digitalRead(inputPin) == LOW)
{
dl = 1;
for (i = 0; i < 30; i++)
{
roll_die();
delay(dl);
dl += 5;
}
}
}
return 0;
}

static void die(int sig)
{
int i;
for (i = 0; i < MAX_NUM; i++)
digitalWrite(pins[i], LOW);
if (sig != 0 && sig != 2)
(void)fprintf(stderr, “caught signal %dn”, sig);
if (sig == 2)
(void)fprintf(stderr, “Exiting due to Ctrl + Cn”);
exit(0);
}

void roll_die()
{
int i, r;

r = rand() % MAX_DIG;
for (i = 0; i < 7; i++)
digitalWrite(pins[i], pips[r][i]);
}
