Taste of Raspberry Pi


Days ago i got play with Raspberry Pi-2 Model B.
It was really awsome to play with it. What attract me is the terminderious power it has regardless of being so tiny on size. I had chance to try different Raspberry Pi OS with it.

  • Raspbian 
is the recomended OS by raspberrypi.org.
Few strength of raspbian is
- easy access to GPIO pin. a mere echo and cat could control the voltage in and out of the pins
- ssh server by default
- ip can be set on /boot/cmdline.txt.
Hence no dispaly is required to access it
- give ip added on /boot/cmdline.txt
- give static ip to your machine on the same range of ip assigned to raspi
- ssh to raspi using default account "pi" with password "raspberry"

I can access the GPIO pin easily. With as simple shell script and my DIY hardware, i successed to seven segment display using 7 LEDs. 


Similary using LDR's, it could be used to count the people/object passing by. 


But one problem i faced with Raspeian is that i can't successed to install flash and hence gives me trouble to access some content on site. But ya may have switched to another OS soon before digging more. :) 
  • Ubuntu Mate 

is a nice distribution for using raspi as a computer. Download it from https://www.raspberrypi.org/downloads  
I successed to install flash, chromium browser and hence my raspi become a tiny netpc. 

Download the pepperflash and extract 
wget http://odroidxu.leeharris.me.uk/PepperFlash-15.0.0.152.r2-armv7h.tar.gz 
tar -xzf PepperFlash-15.0.0.152.r2-armv7h.tar.gz 
give permission 
chmod +x *
Copy the extracted files to plugins directory of chromium 
sudo cp * /usr/lib/chromium/plugins 
Edit chromium config to link the pepperflash with chromium 
sudo nano /etc/chromium/default CHROMIUM_FLAGS="--ppapi-flash-path=/usr/lib/chromium/plugins/libpepflashplayer.so --ppapi-flash-version=15.0.0.152 -password-store=detect -user-data-dir" 
  • EXTON Linux 
Another nicer distro for using raspi as net client.
It is an ubuntu derivatives have Chromium,flash and the flash works by default. 

You may need to set the HDMI audio out. check /boot/config.txt 
If wireless doungle is not detected, you may need to create/edit /etc/wpa_supplicant/wpa_supplicant.conf (google for what to edit)

Hacking with CashOnAd

"Cash on ad" was a new an innovative technique on the advertising industry. After installing an app on your android phone you will be paid for watching ads. That app will play an advertisement each time u receive a call. And the company behind will pay you few cents for viewing the ad. F1 soft had released such app and I was curious to try it. Installed it and it works well. But the sad fact is that I rarely receive call and hence the earning is negligible. Taking advantage of my rooted Galaxy Pop GT-S5570, I explored the internal database of this app. I was amazed to see that all the records are on plain text. Few records are on XML file and few records are on sqlite database and all are readable. Then after I started writing an app for android to exploit this app's record keeping. I wrote an app which will modify the target app's XML and database. I named it <a href="https://github.com/scvishnu7/CashOnClick" > CashOnClick. </a>  Which basically...

First solo overnight cycling experience part-2

Image
Day 2 It was hard for me to woke up this day. It was around 8:00 am when I finally got out of bed. The due were frozen on the grass tip and hence it looked pretty white outside. But the sun had already up on the sky to make the environment warm again. Packed the bag again and had noodles as breakfast as there was no alternative this early. The National Park office was nearby the hotel and the officer came to me to ask about the ticket. But as there were no National park office from where I entered, I had to buy the ticket there. I was shocked to know that I had to pay double of my ticket for my bike. NRs 56 for me and NRs 100 for my bike. I was shocked more to know that few month ago the ticket for mountain bike was NRs 1000 ($10). :( Anyway paid that and on the way at 8:50 am. Route that day was mostly unknown. 90% of the route was complete inside the national park. But as I got enough rest that night I could paddle easily. And another good news was that the path was expected to be do...
