Changed line 11 from:
* sound selector IC with inputs from tuners and other internal/external sources, best would be an integrated pre-amp

Changed line 6 from:
* a big nice LCD panel with backlight (why not colour?)
to:
* a big nice graphic LCD panel with backlight (why not colour?)
Changed lines 8-10 from:
* the selection wheel (rotary knob) is a nice idea.
* A hi quality DUAL tuner with RDS support
* the amplifier is not really needed because there are lot of cheap solutions in the market. However, it would be nice if we could fit the external amplifier just behind the front panel.
to:
* the selection wheel (rotary knob) is a nice idea (or maybe two of them).
* A Hi-Quality DUAL tuner with RDS support
* the amplifier is not really needed because there are lot of cheap solutions in the market. However, it would be nice if we could fit the external amplifier just behind the front panel. (maybe an amplifier modul, which can be fitted in when needed)

The OpenHU project goal is to design an open source car radio replacement.

The features to be implemented are:
* a big nice LCD panel with backlight (why not colour?)
* a standard car radio form factor so it can be installed easily in any car. This means that the LCD should be rather large and not too high.
* the selection wheel (rotary knob) is a nice idea.
* A hi quality DUAL tuner with RDS support (
* the amplifier is not really needed because there are lot of cheap solutions in the market. However, it would be nice if we could fit the external amplifier just behind the front panel.
* any simple protocol for controlling an external mp3 player. For me, I would implement a single wire bidirectionnal asyncronous serial protocol (like the archos remote control link) Maybe several protocols could be supported.

Some preliminary specs:
* Atmel AtMega128 based
* TEA5757 for the fm tuners
* SAA6588 for RDS
* LCD: to be decided

cad software: to be decided

source repository: I propose my subversion repository.
