Remote Controlled Quadcopter Based On Raspberry Pi

Raspberry Pi Intro

We have seen a lot of remote controlled quadcopters based on many micro processors or dedicated flight controllers, but not many people would have thought of running a Linux machine on a quadcopter! Since Raspberry Pi has been very popular these years, and the it’s compact size and computation power compared to most micro-controllers, it would make a good flight controller.

The PiCopter is a remote controlled quadcopter based on a Raspberry Pi. The Raspberry Pi handles all the flight control without using a micro controller like Arduino.

However many people have doubt about Raspberry Pi doesn’t run in real time so might have trouble getting sensor data and sending commands to the motor in the right timing, eventually leads to instability. But Marlon explains “Hard real time” is not required (no need for real time kernel, only stardard Raspbian) as you only have to update the motors with at least 10hz.

Raspberry Pi Plex Media Center Using Rasplex

If you’re a Raspberry Pi media centre user and you have tried Raspbmc and had no luck, or want a alternative solution for a media center software, Raspberry Pi Plex or Rasplex might be the answer. 

What is the Raspberry Pi Plex or Rasplex

Rasplex is a Plex package for Raspberry Pi.  Plex itself is a package based on XBMC, but separates the front-end player from the back-end database, which means that you can have multiple client devices connected to one media server. It is a open, platform-independent home entertainment system. You can play media from any of the machines you have cluttering up the house using the RasPlex media server.

How To Play Video On Raspberry Pi?

How to play video on Raspberry Pi?

The first few things you want to do on the Pi is probably to play video on it. Play Video on Raspberry Pi is actually quite easy. You can use a media player called “omxplayer”. This software comes with Wheezy or Raspbian by default. To play video simply type in this command in the terminal.

omxplayer -o hdmi /path/to/filename.mp4

The -o hdmi enables sounds output on the HDMI port.

If it doesn’t work or you don’t think it’s installed, you can try to follow the instructions here to download and install it.

With this player, you don’t even need to enter the GUI (StartX) to play the videos! really awesome stuff.

Alternatively you can install XBMC instead. It’s a great Media center software which is also plays videos. I wrote a post about it here.

Raspberry Pi Heat Sink – Do you need it?

Do We Need Raspberry Pi Heat Sink For Cooling?

Some people believe Raspberry Pi Heat Sink is necessary. But for any normal use you do not need to cool the chips on the PI with heat sink, unless they get much hotter than a 100 degrees Celsius! You can find an example of an absolute maximum temperature for silicon devices for example.

Obviously operating any practical device at such temperature is very often unlikely, and such temperature limits are only practical in very special cases, like deep sea oil drilling installations.
