Samsung Galaxy S2 plus

September 12, 2013 2 comments

Had an interesting encounter with this mobile phone. I bought one in April and right from the start it started to reboot itself everytime I was on the way and using internet. When I per example wanted to browse the internet during my ride to work (with the train), the phone rebooted itself. This kind of behaviour was looping until I stayed static in one place. I concluded that it has something to do with the changing of the base antennas. I sent the phone 4 time to the warranty reparation, each time it was supposed to be fixed, yet the problem remained. You can immagine how happy it made me. Everytime I wanted to use the navigation on the phone (online one) the phone was just resetting itself. The people working in the repair shop said they cannot test it outside, as it is forbidden to take the clients phones anywhere.

 

Yesterday I realized, that this happens only with the Swiss Orange network. After I bought a sunrise prepaid version, the trouble was suddenly gone. Tommorrow I will go to the local orange shop and try make things straight!

Atmel Car V0.1

September 9, 2013 Leave a comment

As promised, I will continue today. Yesterday I mentioned about the projects that I would be doing. Today I will describe what was already done and what are the next steps.

So far, I’ve bought a simple remote controlled car, disassembled it, removed the original circuit. Then I used two external servo motors, took their circuit, and connected it to the electro motors in the car. I screwed the Atmel research board on the “trunk” of the car and mounted a bluetooth module on roof.  I also connected the modules between each other.

  • Front wheels on the PIN PD7
  • Back wheels on the PIN PB3
  • Bluetooth module BT0417C works over UART standard so I plugged it to PD0 (Tx) and and PD1 (Rx) on Atmel MCU.

Assembled everything again. I am really sorry for the bad pictures but I have a supplementary phone which is not the best machine in the world :).

I also wrote a short “dummy” projects which steers the car in a random way. So every 2 seconds the speed and direction of the car changes. Everything so far easy and simple, but it still takes some time.

The next step that awaits me is to define a standart that will help me get the data from the Phone to the MCU and the other way around. I thought of something like a aJSON or jsmn, do not know yet.

And the most important thing, start programming the Android. I do not know why, but I never managed to come further as “hello world” with the template that is already made for you in the Android SDK.

Stay tuned

Hello gente :)

Hey!
Apropriatelly, first things first, my name is Matija. I’m from a small little country of Slovenija, which lays on place where east meets west,  and north meets south. I moved recently to Switzerland, as the faith guided me there.

Why did I start to write the blog? Especially for me and myself. I would like to have a journal of my own, diary that shows me where am I, what am I doing and where am I going. This blog will be mostly dedicated to my life and work that I do in a certain moment. My life is currently on a crossroad, as I recently finished formal education and still trying to get the first (real) job.  Since June I am officially an Engineer of Computer and Information science. As I like programming more and more I decided to do some home projects. During the workflow of a certain project I will try to explain it,  document it with pictures and describe how I made it, toghether with source code. Currently I am using VS 2010 for PC applications and AVRS 6.0 for microcontroller applications (which I like more :-)). Beside that I will show you new tricks from my dog and other events from my life. I hope you would enjoy it.
