I think this is great, you're giving it some life! I'm actually a Hammond organist. Mine's just like that one, except it uses a tube system instead of a solid state one. The Hammonds are by far the most valuable and desirable as antique instruments. Any tonewheel organ that isn't a Hammond isn't particularly valuable in its original state, but it makes for a great steampunk keyboard! Rock on, dude! :D

I don't see the point of them. The bare ATmega88 (DIL package) is powerful and user friendly as it is.


Currently, I don't have any plans to make another one. But I might change my mind.

How do you restart bash in tty0? For some reason my bash has died in all tty's (Ctrl-Alt-Fn). I does not show the login prompt anymore.

How can I restart it? I cannot reboot the machine. I can ssh into it from another machine.

I don't know what's wrong in your particular case, but it's init (pid 1) that's supposed to (re-)start the login program in each terminal. You can modify init's configuration at runtime by editing /etc/inittab and then doing "kill -HUP 1". But it's probably not an error in the configuration file, so use ps(1) to investigate what processes are running in the terminals.

Hi, amazing work -amazing result. The chipophone really recreates the NES sounds perfectly (pulse,p50%,p25%,p12%, tri, noise..) however, as a former amigatracker-nerd, I remember the voices for the music where made up of short digital waveforms (often handdrawn), Is there a way to get these sounds into the chipophone aswell?

Hey Linus, I got acquainted with your work through the Chipophone demonstration video and as if that wasn't impressive enough I browsed through your homepage and other video's a little bit and I'm blown away. I used to be a chiptune (see http://www.youtube.com/watch?v=u6f9DqJ4Vl0 - you may or may not have seen my nickname or group come by..) and assembler aficionado myself and I was highly interested in scene productions myself some 10-15 years ago, and I've never or rarely encountered someone with such a diverse and extensive set of skills of you. Anyway, as far as programming goes, have you ever delved into the topic of metamorphic code, ie. code that (fully) reprograms itself? It was (is?) mainly used in (demonstrational) computer viruses so anti-virus couldn't detect it by seeking for fixed binary strings and it's a great brain excercise to program.

I wish I still had the dedication to occupy myself with such pet-projects.

Truly an amazing and incredible project. A fantastic array of sound. I'm looking forward to hearing the sound with the spring reverb in circuit, although a more reliable and stable reverb can be made with the AVR as well. But the spring reverb is more authentic, and more challenging to interface.

Very good article...
We want the part II were the concepts gets even closer to the Linux implementation...

just an example:
an xterm session under ssh when resized makes the TTY device to adjust the terminal size and generate SIGWINCH signal for the running app to know about the change...
but if the xterm is under a serial line when resize occurs NOTHING happens (not kernel side size update, not SIGWINCH signal)... I know under serial line xterm does not communicate the size change, well where is the the place to patch in order to solve this, from the xterm side it would be very easy to send a escape sequence telling the TTY driver the new size but this driver should be patched for catching it and react as in the ssh case....

Thanks for your out of ordinary (little or inexistant content + lot of google adds) article. I hope we can get a deeper version someday.

Why you haven't used the already present power supply and power amplifier to have internal amplifcation? I think most the components are already there. If the problem is of dead electrolytics, you can even try to reform the original ones.

Hello lft,

Syntax highlighting is simply enhancing perceptible information. It redundantly presents essential information (i.e. the code). Syntax highlight does not *add* information, it enhances it.

It's one of the basic principles of design, and since you're into typography I kinda expected you to be familiar with this.

I always smile at hardcore coders with black&white screens, who think basic principles of cognitive psychology don't apply to them :)

Hi Linus,
I also disagree with you. OTOH, I want to point out that there *are* sensible and stupid syntax highlighters and color schemes. The example that you provided is indeed a bad one: I don't need strings, numbers, and operators to be colored differently.
What I *do* need is indeed coloring of comments and high-level identifiers, i.e. function/class/method names.
That really enhances the perception when skimming through code.
Have a nice day,
Hans
PS: I am sorry, I have not read most of the anonymous comments yet, so maybe this has been pointed out earlier.

You seem to respond only to those that either

1 -- Speak hardcore nerd

2 -- tell you off.

So here goes. E = mc*mc. Pi = 3.14159265. There are four stages of matter. Yo momma. Gotcha yet? Good. There are basically 3 levels of nerd that come to this site. lvl 1 -- soft nerds, can only understand that this instrument makes cool sounds and are here to congratulate you/ask you to build one for them. 2 -- the middle class nerd, understands the things this machine does, but doesn't understand a single thing about how it's made. We need this midi file, or w/e it is that's missing and keeping us from making it. We've seen this thing, and we need this thing. This thing is the son of epic and uberleet, and yet, we can't reach it. The softies don't care enough, and lvl 3s know how you made it and are probably off making a prototype of their own. I don't care if you charge and make an instruction book or anything, that's on you. All i know is, I need this chipophone.

It's a valid point, but I'd have to reverse engineer the entire power supply, because I don't want to meddle with a 230 Volt circuit unless I understand it. Thus, using an off-the-shelf power supply is quicker and safer, apart from being more efficient.

Do you also consider the prose example to be enhanced? My point is that enhancing and distracting are two sides of the same coin.


On the contrary, a basic rule of thumb of typography is to stick to a single font. SOME people use CAPS to indicate EMPHASIS, thus BREAKING this rule. I find that it makes the text less readable.


I'm happy to have made you smile.

I'm astonished you managed to make such an amazing synth using an ATmega88. I've found other instructions and code online for making similar synths using similar microcontrollers, but they all seem to be monophonic and don't include as many features.

You mentioned that the synth takes MIDI input, could you actually just hook up any MIDI controller and control the synth with that? Or are there some other special instructions that you've created which are Chipophone specific?

I love the sound of the synth, you're simply amazing as a programmer and composer.

I know many people have asked, and you seem reluctant, but everyone would greatly appreciate it if you released the source for the synth, even if you didn't clean it up. If you don't want to release it, I know that I would even love the opprotunity to buy a preprogrammed ATmega88 from you and I'm sure others would, too.

Well, for now I guess I'll have to look into trying to duplicate your programming achievement on my own ATmega88. Thanks for the inspiration!

The prose is not enhanced because the colors don't enhance essential information. In your example, you emphasize verbs and nouns. These are an important property of linguistics, but it is not essential to recognize these words as nouns, verbs or adjectives to comprehend the story. I have no idea what "type" of words you used in all the sentences of your article, but I understood it perfectly well anyway.

To put it another way: it's not essential to know if the word "was" is a noun or a verb in the sentence "Alice was not a bit hurt", whether it is highlighted or not. But it *is* essential to know that "char" indicates a data type, whether it is highlighted or not.


I think you might have misunderstood my point. Contrast most definitely is one of the basic principles of design. It is brought to code in the form of syntax highlighting through colors, and brought to written language in the form of a change in size, weight, style, spacing or orientation of the typeface.

You use it on your site too: headings and subheading are written with a larger and bolder font, quoted text is encapsulated in a container that separates it from the normal text, links are underlined and have a different color than the normal text.

Your "PEOPLE WHO USE CAPS"-example is simply an example of improper use of emphasis, not a case *against* emphasis. It's like putting green text on a purple background and saying "see, syntax highlighting is evil because this particular example is unreadable!"


This was not meant to come across as a sneer at you. I enjoyed reading the article, the comments and your reply. I think it's an interesting discussion and I'm simply trying to understand your point of view. To be honest, your rebuttals are not really convincing and often contradictory.

Oh, but it is quite essential to know what the word "was" means in order to comprehend the sentence. Part of this knowledge is the fact that the word is a verb -- although it's not essential to know that "verb" is the common terminology for this property.

Likewise, it is essential to know that "char" (or, perhaps more to the point, "person" in a piece of software where it has been declared as such) is a type. Without this knowledge, comprehension and ability to modify the code without introducing bugs would be all but impossible.

But this academic grouping has no business being at the front of the mind during programming; the programmer should be as familiar with the fundamental meaning of the word "char" as he is with the word "was". The fact that "was" and "running" have the same colour is uninteresting when reading a text, since they mean different things, and in a similar vein "char" and "person" are two different types, and it makes more sense to think of them as two separate entities in their own right, than as two instances of "type".


Good point. I see the problems with my example. Nevertheless, I maintain that while some typographic highlighting makes sense (such as indentation and extra whitespace, where it clarifies the intention of the code), automatic highlighting based on syntax is distracting because it emphasizes the shallow syntactic level of the code, rather than the deep semantic level.


I apologize for jumping to that conclusion.
