Arduino RTC

No comments · Posted by opcode1300 in Hardware, Windows

Quick code to set the RTC for my arduino using the sketch from here

It’s copy/paste, not as good as NTP but better then guessing (and ill fix that when i get my ethernet shield (maybe)

secret project under way

using System;
using System.Collections.Generic;

using System.IO.Ports;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            //Example to set the time for 02-Feb-09 @ 19:57:11 for the 3 day of the week, use this command - T1157193020209 
            //    T|11|57|19|3|02|02|09
            // Creates and initializes a DateTimeFormatInfo associated with the en-US culture.
            DateTime CurrTime = DateTime.Now;
            string[] setTimeString_tmp;
            string setTimeString="";
            setTimeString_tmp = new string[8];
            setTimeString_tmp[0] = 'T'.ToString();
            setTimeString_tmp[1] = CurrTime.ToString("ss"); // Sec (00-59) [##]
            setTimeString_tmp[2] = CurrTime.ToString("mm"); //Min (00-59) [##]
            setTimeString_tmp[3] = CurrTime.ToString("HH"); //Hr (24) [##]
            setTimeString_tmp[4] = (CurrTime.DayOfWeek+1).ToString("d"); //Day of week (1-7) [#]
            setTimeString_tmp[5] = CurrTime.ToString("dd"); //Day of Month (01-31) [##]
            setTimeString_tmp[6] = CurrTime.ToString("MM"); //Month [##] (01-12)
            setTimeString_tmp[7] = CurrTime.ToString("yy"); //[##] (00-99)

foreach (string i in setTimeString_tmp)
            {
                setTimeString += i;
            }

Console.WriteLine(setTimeString);

Validate ALL input!!!

No comments · Posted by Alex in MAKE/HACK, Software

Today one of the new guys at work ask me a question. “Can our web portal submit “Severity 1″ support request?”

The standard answer has always been ‘No.”, but today I figured it was time to test that.

Start Tamperdata and log into the portal. Dispatch request as normal with one exception. change ‘severity’ value to 1 and submit. you now have a ‘sev1d’ support request without a phone call.

Software:

Firefox with Tamperdata add-on

Dynamic PHP Image with countdown (I am a Dad!!!)

1 Comment · Posted by opcode1300 in Site, Software

I have not said much on the internet about it, but I am going to be a dad.
And the sonograms to determine the sex of the baby are coming up. So I figured what better way to count it down then w/ a little code. =)

Code from here (why reinvent the wheel..)

**EDIT**

Changed the way the time was calculated to make it easier to read.

Awesome's Countdown

<?php

header("Content-type: image/png");  
// Tell the browser to display the page as an image.

// Define your target date here
$targetYear  = 2010;
$targetMonth = 03;
$targetDay   = 30;
$targetHour  = 9;
$targetMinute= 15;
$targetSecond= 00;

date_default_timezone_set ('America/New_York');
// Sets the default time zone, in this case GMT -05
       
$dateFormat = ( "Y-m-d H:i:s" );
// Check the PHP Documentation for date uses.

$targetDate = mktime ($targetHour,$targetMinute,$targetSecond,$targetMonth,$targetDay,$targetYear,1);
// Sets up our timer

$actualDate = time();
// Gets the actual date

$secondsDiff = $targetDate - $actualDate;
// Finds the difference between the target date and the actual date
if ($secondsDiff > 0)
{
// These do some simple arithmatic to get days, hours, and minutes out of seconds.
$dayInSec  = 86400;
$hourInSec = 3600;
$minuteInSec = 60;

$remainingDay     = floor ($secondsDiff /$dayInSec);
$secondsDiff     -= $remainingDay * $dayInSec;

$remainingHour    = floor ($secondsDiff /$hourInSec);
$secondsDiff     -= $remainingHour * $hourInSec;

$remainingMinutes = floor ($secondsDiff /$minuteInSec);
$secondsDiff     -= $remainingMinutes * $minuteInSec;

$remainingSeconds = $secondsDiff;
       
$targetDateDisplay = date($dateFormat,$targetDate);

$actualDateDisplay = date($dateFormat,$actualDate);

// Sets up displays of actual and target

// if in the future
$string = $remainingDay." Days, ".$remainingHour." Hours, ".$remainingMinutes." Minutes, ".$remainingSeconds." Seconds";
$string2 = "Until we find out if 'Awesome' is a boy or girl...";
}else {
//if countdown is over
$string = "The Wait is over...";
$string2 = "It's a boy!!";
// Two strings
}

$dx = 10;
$dy = 10;
/* Displacement of the text from the top right corner
This should be measured in Pixels. */

$image = imagecreatefrompng ( "baboon.png" );
// We want to create an instance of our image to work with

$text_color = imagecolorallocate ( $image, 30, 30, 30 );
/* The imagecolorallocate function only accepts RGB values.
If you need to convert hex to rgb, check the PHP Documentation */

$font_size = 5;
// Needs to be between 1 and 5.

imagestring ( $image, $font_size, $dx, $dy, $string, $text_color );
imagestring ( $image, $font_size - 1, $dx, $dy + 12, $string2, $text_color );
// The actual function that puts our string on to the image.

imagepng ( $image );
// Sends our image to the browser.

imagedestroy ( $image );
/* Not required, but good practice.  The image gets
destroyed at the end of the script anyways */
