The hardware is very, very simple. The output is PORTD, with the following schematic (bits 0 - 7 refer to Arduino digital pins 0 - 7). This is a resistor ladder.

I could not help my self so I built a four bit version, since I want to hear that sound. Also I found this: http://en.wikipedia.org/wiki/Covox_Speech_Thing witch is a old soundcard witch used the same idea.
