Looks nice. Wouldn't it be easier to read if you used two different color leds? e.g. orange for 10's and green for 5/1's

The "in box version" will have LEDs in two different colors.

I use an USB sound stick now; sound quality is better than with the built in one.

What I am still looking for is a software / addon for mpd that can be used as an eqalizer and that can as well be controlled using the remote.
(I still remember the "Loudness" button on Stereo Amps in the seventies ... something like that would be cool ....)

Any ideas?

I see the label on the box is still blank?!

Search for pulseaudio-equalizer . The newest rasbian uses pulseaudio for sound-management. I cannot test it here, because I have reverted back no no pulseaudio. This because it added a few seconds of delay at startup. I hate waiting :-)

A nice new feature for my radio:

Pressing a special button on my remote executes the following:

mpc -f %title% | head -1 | mail -s Titel schwabinger@blabla.de

This command sends the title of the song that is just playing to my email account ..... very useful when you listen to a song that you have known for 40 years but never have known what the title of this so familar song was ....

In order to make your linux system send the mail you have to install ssmtp first:

Enjoy!

Nice addition Schwabinger. I myself store all the songs played, and their start-time into a file inside the /tmp folder. So I'll have to telnet into the router to see the previous song. To view the current song, it's easier to just launch my web-interface.

Hi Gerben,
that really looks cool!

I recently have connected a 16x2 LCD to the pi. (I want a solution without a screen, be it on a notebook or a smartphone).
Fotos will follow

Looks great. Now, all it needs is a nice case.
Thanks for sharing.

Here comes the box

What is still missing is a way to make use of the back light. This is the LCD that I use:

http://www.produktinfo.conrad.com/daten ... S_16X2.pdf

This documentation says the following about using the backlight:

"DRIVING THE LED THROUGH A CURRENT LIMITING RESISTANCE (RA) WHICH IS ALREADY
INCLUDED IN THE LCM, BY EXTERNAL 5V TO J1 AND J2 BETWEEN PIN 1 AND PIN 2."

No idea, what that means .... PIN 1 is GND, PIN 2 is 5V, both are connected to the PI anyway (otherwise the LED would not work.) But what do J1 and J2 mean?
