Making music using a computer, Wiimote and PureData

An article that appeared on the Create Digital Music website, about making music using the WiiMote and a computer, drew my attention. Several hints were given on the how to, but as always in doing new things the information was scattered everywhere and nowhere. After reading many articles and watching many videos I found out how to realize a working setup for myself. In this article I’ll try to explain the steps needed to create a working setup for yourself.

Upgrading your SqueezeCenter server on Ubuntu

In a previous article I tried to explain the installation of the Squeezebox Server on the Tonido Plug. In this article I’ll try to explain how to perform an upgrade of your existing Squeezecenter Server on Tonido (or Ubuntu as the Tonido Plug is based on Ubuntu 9.04).

What you’re going to do is actually remove the old installation of the Squuezecenter server and install a new copy of the Squuezecenter server.

Prerequisites (what you need to get it working):

  • Hardware
    • Computer
    • TonidoPlug (optionally)
    • Internet connection
  • Software
    • Windows users might need Putty

 

The first thing you need to do is remove the ‘old’ installation of the Squuezecenter server, by SSH-ing (Windows user might want to use Putty) the following command:

apt-get purge –yes squeezeboxserver

 

Next thing is cleaning up your Ubuntu installation by entering:

apt-get autoclean

 

You might want to update your Ubuntu installation by using the following commands:

apt-get update
apt-get upgrade

Now you are ready to install the latest version of Squuezecenter server (Check the Squeezebox server version and location, by locating the latest version using your internet browser).

wget http://downloads.slimdevices.com/SqueezeboxServer_v7.5.3/squeezeboxserver_7.5.3_all.deb
dpkg -i squeezeboxserver_7.5.3_all.deb
apt-get -f install

 

Now your Squeezebox Server should be upgraded, you can check it by locating it in your internet browser
http://YourSqueezeboxServerName:9000/
or
http://YourSqueezeboxServerIpAddress:9000/

 

If needed you can manually stop or start your Squeezebox Server

/etc/init.d/squeezeboxserver stop
/etc/init.d/squeezeboxserver start

How to erase (or clean) a disk using Ubuntu

Sometimes you just want to clean a USB stick, SD Card or USB disk, and the only thing you’ve got is Ubuntu running on your system.

Well that is no problem, I’ll explain how simple it is…

Cleaning, erasing, wiping a USB stick, SD Card or USB disk can be done in just 3 simple steps:

  • Connect your disk
  • Identify the disk on your system
  • Clean / wipe your disk

Step 1 – Connect your disk
Connect your USB stick, SD Card or USB disk to your computer and mount your disk (you can do that by double clicking its icon on your desktop).

 

Step 2 – Identify the disk on your system
Open a terminal:

df -h

or, you can use

sudo fdisk -l

Identify your disk (you can look at it’s size or partition scheme)

 

Step 3 – Clean / wipe your disk
The following command is a simple example to understand the use of dd. Do not simply copy it and use it in a terminal !!! Remember the order of the options “input file (if=)“ and “output file (of=)” , DO NOT reverse them !!!

In my case (the example below), I identified my disk that I wanted to clean as /dev/sdg.
So my output file (or of) will be /dev/sdg this will result in of=/dev/sdg

Open a terminal:

sudo dd if=/dev/zero of=/dev/sdg

 

When the dd command is issued and ready, make sure all data is written to disk by typing the folowing in your terminal:

sync
