Tilt shift effect open source software

Hi, this is a quick post, just to say that I created a simple software (this is the first version, I'll add some improvements) to create tilt shift effect in photos.
Here is the google code project link:
http://code.google.com/p/open-tilt-shift/
This is basically how it works (this photo is from an article of another blog):

If you want to check the processing code, you can download it from the google code project page.
I hope you like this post, if you have any question comment or send me an email to damianoandre@gmail.com

USB breadboard power supply

Today I'm posting about a simple USB breadboard 5v power supply I think there is nothing to explain, just take your solder and make an useful power supply for all your projects.
Here are some photos of mine:

I know this isn't a great post, but of course this is a nice tool that you can use for all your projects.
If you have any question comment or send me an e-mail to damianoandre@gmail.com

-ferrite ring (toroid)
-LED
-1k ohm resistor
-some wires

Here is a simple diagram:

Open source game engine: maratis3d

Hi, today i'm posting about a really versatile and easy to use open source game engine, it's called maratis3d.
I think it's a good point to start game development, it supports many cool features like lua scripting, full blender integration (with an addon), sounds, texts and many more...
The only bad thing is that it has a really poor documentation.
I'll not write everything about this game engine because I think it's really noob friendly and with just some tutorials that you can find on youtube you should make a nice little game.
I hope you'll enjoy playing around with that, if you have any question comment or send me an email to damianoandre@gmail.com

Simple javascript countdown script

I've created for a mine project a simple countdown script in JS, I think it's easy to use and really flexible.
Here is the code:

<script>
function countdown() {
    var yourdate = new Date("April 12, 2013 9:30:00");
    var now = new Date();
    var timeDifference = yourdate.getTime() - now.getTime();
    if (timeDifference <= 0) {
        clearTimeout(timer);
        //any other code to run on countdown completition
    }
    var seconds = Math.floor(timeDifference / 1000);
    var minutes = Math.floor(seconds / 60);
    var hours = Math.floor(minutes / 60);
    var days = Math.floor(hours / 24);
    hours %= 24;
    minutes %= 60;
    seconds %= 60;
    document.getElementById("days").innerHTML = days;
    document.getElementById("hours").innerHTML = hours;
    document.getElementById("minutes").innerHTML = minutes;
    document.getElementById("seconds").innerHTML = seconds;
    var timer = setTimeout('countdown()',1000);
}
</script>
<style>
#cdcontainer{
text-align: center;
}
#countdown li{
display: inline;
list-style-type: none;
padding-right: 10px;
font-size: 60px;
background: #1560BD;
}
</style>
<body onload="countdown()">
<div id="cdcontainer">
<ul id="countdown">
<li id="days"></li>
<li id="hours"></li>
<li id="minutes"></li>
<li id="seconds"></li>
</ul>
</div>
</body>

I hope this simple script will help you, for any information comment or send me an e-mail to damianoandre@gmail.com

Ice lamp

Today I'm gonna talk about a cool and simple project: an ice lamp.
To start you need:

-rubber balloon
-1 LED
-some wires
-a 9v battery

First of all solder or connect in any other way the LED with you wires.
Then fill the balloon of water and put the LED with its wires inside (some water should get out).

Now put the balloon in a freezer for about 3 hours.

After 3 hours connect your wires to 9v battery and the LED should light up.

Here are some photos of the final result:
