Gravitan – Entertainment App. for Android

Hi my fellow readers,

I’ve been studying on android application development last week.As i was familiar with OpenGL and it’s port for Embedded Systems which is GLES ,i choosed to study on that part first.
I’m planning to make 2D Slingshot based game for Android.So i made a simple demo. to implement main, fundemental structure of the software that is going to be required to build-up a Slingshot game.

How it works:
You can add new circular masses by dragging white circle below the blue line.
As you drag, There you will see a white line appearing , which signifies the launch speed of the mass that will be created as you stop tapping.
I named it Gravitan but it’s simply the predecessor of the upcoming slingshot game. :) here are some screenshots :)

Self-Balancing Robot First Step:The Interaction

Here is the first step in making of Self Balancing Robot. In this step i worked on Bluetooth & Serial Communication.
Communication scheme:
N95 (Bluetooth)—> PC —–( Serial)—-> Arduino
I used the same motor driver shield which i already made back in Narduino Project.
If you havent heard about Narduino Shield and its simple design done on veroboard click here to see it and its circuit diagram.
After the Narduino shield properly connected to motor wires and the supply connection ,  it is time to talk about coding…
Here below , i shared all the codes used in the project.

Self-Balancing robot project starts!

I just had an idea yesterday that can get me to make a self-balancing robot without buying any expensive electronic components.
You know last summer i made a cellphone controlled RC Car which had a tabletpc onboard to get commands via bluetooth.That time , having an onboard tabletpc , save me from buying a bluetooth chip which costs about 60$.This time, to make a self-balancing robot i’ll have to have whether an Accelerometer or a MEMS Gyro to track rotation of the robot.
Those sensors are pretty expensive too.So i’m thinkin about putting my n95 smartphone onto the robot.As i have Accelerometer on the smartphone i can use it to measure rotation movement of the robot.

I tried to explain how it is going to work in the photo.

And the finished robot will look something like this:

 

NarDuino 2.0 !!

Hi my fellow readers,
Today, i’ve been working on re-building my NarDuino car project all day . So why am i rebuilding it?. Because i decided to rebuild the motor driver ,that i’ve used on narduino, onto a veroboard so i can use it later on other motor controlling involved projects. It has been quite an hard thing to do since i have no experience at soldering at all. But i just started and finished it.

After A Long Time

I’m just tired of writing articles that starts with “it has been a long time etc.”.Because i dont like writing so much.Anyway i’m trying to write as soon as i have free time.

So… There are a lot to write.

Lets get started with my first application for Maemo OS.It’s a simple application that calculate degree of a right triangle with a two given data.After a couple of “Hello World” application i just wanted to do something myself.Then this application came up.Infact this is not something new i generally use that right triangle angle calculator function when i learn a new programming language and if i dont have any software ideas.

And… It has been almost two months that i spent with The Nokia N810 tablet.I’m thinking to write a summary of my experiences with this device.Maybe that may help maemo beginners to use their devices with its all capabilities.

By the way i had a problem on my n95 8gb.It was always asking date and time after every restart.I had asked about this on so many discussion board.They said that i had to change its capacitor which saves date and time and i didnt do that.But however after a month it fixed itself i guess :) . It keeps date and time data now.

And.. i had a problem about 3d problem about my ATI video driver.It was causing errors in all 3d softwares such as 3dsmax , NaturalMotion etc. Last weekend i figured out how to fix this problem.i found  that error is happening on firmwares newer than 5.3.1. anyway …

You know i was going to interact my arduino with N810.After a long tiring hardship , I found that my hand-made arduino is not one of the supported devices and that project turned into a disappointment :(.This disappointment cost me about 15bucks , I wish I had bought that roll-up keyboard instead of that usb-serial converter .

By the way, I designed a wrist-case for n810 which I inspired by computer of the orion hacker in chuck the tv serie.I didnt make it.But i make another case to protect screen against stylus-scratches.Because it may cause serious scratches when you try to draw pictures or something in MyPaint or GIMP.

These are the issues of month as far as I remember.Also you can learn more about me from my twitter account.

My First StopMotion ShortMovie:Save The Forests

You know the “Chicken Run” Movie which was about chicken that is trying escape from the farm.Yep, that’s what i’m talking about.

i was working on 3dsmax modelling while i was watching that movie.i spotted something that movie is 3d but it’s not looking like a computer rendered graphic.i searched around the web if there is any renderer plugin or smt. like for 3dsmax.

then i encountered another movie making method which is called as stopmotion.then i wandered and researched on that.and i found a software called as animator dv that make stopmotion movie making easy.

after first 2-3 practice.this short movie came up.

Save The Forests – My First Stop Motion Practice – video powered by Metacafe

infact that was not my point to make a video which says save the forests.u know southpark intro,which scissors cuts papers and characters comes up.i tried to make a movie like that but i noticed smt. that i was trying to make it with a piece of paper from notebook.but in southpark they were making it with carton material.so it’s hard to move papers per frame.

and there was scissors and a piece of paper on the table.then another idea come to my mind about making a movie looking like pacman but this time pacman will be the scissors and the enemy will be paper.

finally this short movie came up from this idea
