Please post at least a part list, or the code for the chip, or some schematics! Even just a detailed guide on how to use it.

Awesome ;).
And the implementation is so simple! I changed the output to stdout instead of stderr. This is my brainfuck interpreter for stdout in one line :

char m[9999],*n[99],*r=m,*p=m+5000,**s=n,d,c; main(){for(read(0,r,4000);c=*r;r++)c-']'||(d>1||(r=*p?*s:(--s,r)),!d||d--),c-'['||d++||(*++s=r),d||(*p+=c=='+',*p-=c=='-',p+=c=='>',p-=c=='<',c-'.'||write(1,p,1),c-','||read(1,p,1));}

Hehe works with your game of life. Honestly that must have taken ages to implement. I get a headache after the first line in your life.bf file ;).

Greets and keep up all your awesome work,

I never will build this stuff, can U make an MP3-album\torrent to listen songs separately? It would be nice. :)

Hi Linus, if you wanna more questions, here they are:

When you use HBlanks for updating the waveform (like in Craft project) how do you keep the sample rate constant during VBlanks?

In Phasor project, does the output signal contain interlaced video? Do I understand correctly that generating a blackwhite composite video signal is much less difficult?

I was wondering about two features of the sound:
1) on the attack of each note, there seems to be a small "noise blast",
2) the notes have a high aliasing content.

For (2), I was under the impression that it came from sampling the waveform at a fixed rate without first filtering it (which would probably require a DSP implementing BLEPs or something similar), but the effect seems extreme. Did you include some kind of non-linear saturation to get that effect?

For (1), I have no idea where that might come from but I like the effect :-)

On the other hand, the interactivity (bass and chords modification in particular) is awesome. That's kind of what I'm trying to achieve with my own project.

I think it should be possible to modify firmware hex file and make it use microcontroller's watchdog after the main program end. The watchdog will restart the whole microcontroller. Or use more stupid way: pull reset low with an external hardware thing. :)

Is it possible to replace the 442 resistors with a more common value like 390 or 470?
Yes. Look at http://en.wikipedia.org/wiki/Resistor_ladder Keep in mind that DAC's output impedance should be low enough to drive 75 ohm load, that is the monitor input impedance. But not too low because microcontroller leg can't give much current.

The hardware/schematics really isn't the problem, it is easy enough to figure out the schematics from the photo in the posting. There is no magic happening there. I'd gladly offer to turn this into a pcb layout.

However, the software is the tricky part. The experience Linus has with chiptunes is not easily reproduced, let alone turned into a sanely working midi synth. So I guess we're out of luck for now.

Bye,
Simon

8 is 1000, and the octopus is in the 4th position with no other critters thus 1000.

I really admire your work, Linus!

Keep up the good work and I'll be checking in once in a while!

Even though I like the songs, haven't exactly hit my personal childhood yet though.. haha didn't get to play any of these games! :(

Any chance for the Pokemon Gameboy songs?
Looking forward to your future projects!

Thank you!

Great job!

I have just a suggestion.
This article can be used as a first step by people (like me...) who don't have a deep knowledge on the topic,
so why not to add a "References" section to help going into more depth?

Cheers!

This is great man! I hope that you could hopefully get picked up to do music for some of the newer games coming out for any platform. That's plain awesome and you know it. I suppose some Japanese dude did that across the planet when we were babies, but whatever man, you nailed it.

I just recently found this ( Via the Chipophone, again, of course ) and I must say that it's a very well done reinterpretion, especially compared to the Midi versions I have heard so far, which appear to be directly transcribed notes without much else.

I would guess that there are lot of elements from the other projects involved, like what you find on "making of chipophone" page, which again links to this:
http://www.linusakesson.net/hardware/chiptune.php

but of course, it would have been cool if Linus put togheter the stuff on this page.

You are absolutely brilliant! I really like the chiptune-specific features of your Chipophone (the chiptune-specific waveforms, the two-key portamento and the drum-kit mode), and right now I'm watching your Int'l Karate cover video - brilliant, just brilliant!
