Beagleboard VGA output

Anonymous
Thu 8-Jul-2010 22:10
Is not the VGA signal peak level 0.7V? every vga module data sheet, vga spec and web documents state this, sync being TTL level 5v, and rgb 0.7v, even the TI Video DACS (THS3185, THS8200) state a 700mV peak level for white

From information in the net, only some non standard monitors use 1v level

http://microvga.com/faq/electrical/what-are-vga-voltage-levels
http://en.wikipedia.org/wiki/Video_Graphics_Array#Technical_details
http://www.ti.com/litv/pdf/slas343a

Or this beacuse the blanking level is 350mV and this offsets the 700mV to be 1v peak white?

Love it! So much so that I'm building my own, but I'm curious about the 442 resistors. That's a really odd value, even if I read it like an SMD part and get 4.4k. Is the value critical, or can I get away with a 4.7k?

Wait, I just realised it's in an R-2R ladder arrangement with the 220ohm resistors. There's actually plenty of room in the stripboard layout to replace each 442 with a pair of 220s in series, so I'll do that instead of sourcing resistors out of E48. :D

And just as quickly realised that I was thinking of the Craft schematic instead of Phasor's. Oops! :)

Anyway, I just finished building it, and it works beautifully! Thanks lft!

The effect on a standard organ known as a Leslie created by a spinning motor creates a Doppler effect, the effect can be heard in acid rock songs such as the Pink Floyd song "On the Run". does your organ have one of these? It's a real neat feature, on a second note, would you ever be willing to release the schematics/Rom of that midi board? I'm thinking of making a chipophone myself.

No, there was no Leslie speaker in it. Everything was solid state except the reverb.

A case against syntax highlighting

Anonymous
Fri 23-Jul-2010 02:18
i agree with most of the pre-commentators. syntax highlighting basicly adds another dimension to visuallizing the hierarchy of the code, like indentation does. i am a novice programmer, but i never found myself thinking about the syntax highlighting, unlike stated in the article. i merely notice when it isnt there, unlike automatic indentation. i see the main purpose for writing code, not for reading it. when i miss a quotation mark or misstype a language keyword, the mistakes are easy to spot.

additionally, colors make your code look much more friendly :)

A case against syntax highlighting

Anonymous
Fri 23-Jul-2010 18:23
I think it's more on the part of the programmer rather than the program you're editing your code in. As a programmer, I make my code readable because it's the right thing to do. Highlighting has never been a hindrance to me, because I never relied on it. I learned about highlighting long after I started programming. I don't use a debugger, I still actually add lines to show me what's been done... Call me old-school, or weird. But good code helps others, as well as you, know what you meant to do. Just like commenting your code.

But I also like Syntax Highlighting. It's something that actually helps me program. I got into my Highlighting area, and added words I know I'll use. Everything that has to do with strings is one color, math functions another. It makes it easy for me to see where things are happening in the program. Yet it's not a crutch or a training wheel, because I don't rely on it. Without it, I can still chart the flow of my program.

I see your point about not starting with it. However, I don't see a reason to get rid of it. I learned to program in BASIC. While BASIC can do things, that doesn't mean that I should have never graduated to C or further because those things help me do things faster. A good analogy would be this. You start in BASIC. Now, you move on to either C or Fortran. Well, some people prefer C and some prefer Fortran. OK, so program in the one you want to. And if you replace C with "Syntax Highlighting", and Fortran with "Syntax Non-Highlighting" there you go. Use what feels right.

Wonderful project! Congrats!

Regarding why they used the light bulb/photoresistor setup for the expression (volume) pedal - all electric organs at that time took at least some design inspiration from the original Hammond organs - the expression pedals in classic tonewheel Hammonds use an air-variable capacitor - the moving parts don't directly contact each other, which makes for a wonderfully quiet pedal (electronically & physically) that won't ever get scratchy. I'd bet the pedal in your organ was designed with that in mind - they may have found that pots available at the time weren't up to it.

Sure, but several youtube commenters have already figured out the answer to this question independently, actually. =) The output from the chipophone was routed to a separate track, which was mixed in afterwards during editing. The volume of the speech track was lowered so the sound from my monitor speaker wouldn't interfere with the real track. It still does, if you listen carefully during the parts where I speak while the synthesizer is sounding.

"It would be fun to extend this into a full-blown irrigation system by building some kind of motorized watering contraption,"

I've always thought the same thing. I've been dreaming about an automated greenhouse. I have all the control side down, but the moisture sensing circuitry was a little bit of a problem for me.

Thanks to you, I have that almost all figured out. The next step is to blend the sensing and controls together.

The problem I'm having is to get an output signal send to the controller once a setpoint is reached.

How about playing some Atari St style tunes by Jochen Hippel (mad max) or Chris Huelsbeck? Turrican or wings of death tunes maybe?

Secondly, have you ever thought about selling one of these? Might be worth a test, I reckon theres a market for this thing. I for one would love to buy one at the right price! (im not rich, sorry...)

Very sweet project. I've been playing around with R-2R ladder DAC's and they're getting really nasty on my breadboards when using the actual resistors ;). Could you possibly give a part# for that R-2R you're using? I'm having trouble finding one that's not surface mount.

A case against syntax highlighting

Anonymous
Sat 24-Jul-2010 13:56
(I didn't read the too many comments before posting)
I do rely on syntax highlighting, and I think that nearly all your points are wrong.

You say the difficulty comes from the semantic of the program, not its syntax. No, it comes from both. I have tried a lot of languages, and never encountered one whose syntax had zero problems, so any help is welcome (besides, knowing several languages means being confused more easily by small syntax differences, unless my editor helps with colors).

You argue that color draw attention too much and that it becomes cognitively harder to read because of the mental overhead of processing colors.
That is very true if you use bright primary colors like in your Alice example, but a good (sober) color scheme actually do not distract, only give more information to the reader. Another thing: prose is very different from code, since its syntax is not at all relevant in the same way. Today, most default color schemes for code are not very colorful.

Concerning the mental overhead, you'll find that text color is actually processed at a nearly-hardware level by the brain. Once you are accustomed to read colored valid code, colors will only stand out when the code is invalid. The rest of the time, when the code is syntaxically valid, I can fully concentrate on the semantics. I'd rather discover (and correct) any syntax error sooner than later: running a compiler is *way* slower than having your editor tell you. And this kind of time waste is one of the very worst in software engineering.

You mention the "only" use you found for colors: knowing if you are in a comment. This can be extended easily to knowing whether you are in a valid string, or whether you made a mistake in the quoting inside the string. So that instantly makes two use cases (ok that was easy).

You say that colors make it more difficult to find bugs. Could it be that you have never encoutered a bug that was caused by syntax alone ? Compilers don't catch everything, and sometimes you use interpreters, which choke on syntax at runtime.

Your whole comparison to training wheels implicitly assumes that the end goal is knowing how to read/write code without colors. But since it is more difficult without colors, it is also less desirable to do so. My end goal is coding better and faster, so I choose to be helped by tools like a good editor and syntax highlighting. If I'm less good at writing code when there is no color, it does not matter at all, since I choosed not do otherwise.

So, I'm not convinced at all. I know by experience that with colors I can read/write better code more easily and faster. Can it really not be the case for you?

Truly amazing. Not only that it works but that it works so well and seems very feature complete and able to mimic the sound of all the different old chips. Also you play very nicely. As for requests of music I would like to hear some non-chiptunes played on this thing. Or perhaps some chiptunes remade to sound like from another system. Anyways. Awesome project indeed!

In case you're curious, the volume pedal design with the light and photocell is still very common. No moving parts to wear out, you see. But it is nonlinear and requires analog support circuitry.

In the digital domain, you'd use some kind of quadrature encoder and process the pulses directly. But unless you can actuate it directly over the distance of pedal travel, you're going to have some kind of mechanical system to convert a dozen degrees of rotation or a couple of cm of travel into 256 MIDI values. Look for components which will tolerate a million cycles of use.

it's not a specific component you make it using a series of resistors ...
http://en.wikipedia.org/wiki/Resistor_ladder but it's easier to use the PWM trick mentioned earlier at least less parts. http://www.k9spud.com/traxmod/pwmdac.php

Very cool! BTW I love your website, many excellent projects.

I was wondering if you did anything special to keep the noise low. I think the audio is significantly clearer than on some of your other projects, like the "Swan".

I've experimented with sound using several different AVRs PWM, R2R, and an 8-bit DAC and have found it difficult to get beyond telephone quality. I noticed they all generate noise on the power line, and the distortion varies a little from chip to chip. For what it's worth the Attiny45 does have high frequency PWM via an internal PLL, but it makes a distorted square wave (to my ears at least).

The process of daemonizing is covered elsewhere, easy to Google. It involved forking, killing the parent, then calling setsid() in the child, and optionally chdir()ing to / and closing stdin/stdout/stderr.

I am currently working on writing a toy OS, and this was very useful in its treatment of the basic structure of the TTY subsystem. Thanks.

The TTY demystified

Ralph Corderoy
Sun 25-Jul-2010 16:22
Nice article, various points...

The erase and kill characters used to be # and @, and as you were printing on paper there was no rubbing out, so you might see

$ ls @wc -l /etvc##c/passwd
42 /etc/passwd
$

where the `@' was killing the whole line entered so far and the `##' was erasing the preceding `vc'.

It's only modern shell that provide line editing, hence shell history substitutions like `!!' and `!$' existing. If /bin/sh is a plain old non-line-editing shell on your system then you can see the difference in tty settings by using `stty -a' from another terminal to capture the differences. Don't run stty(1) from, e.g., the bash shell since the shell will alter the tty settings before running stty. Here, bash has the literal next character, lnext, being undefined and turns off -icrnl, -icanon, and -echo.

The above example of # and @ was achieved by

$ sh
$ stty erase \# kill @ -crterase -echok
$ ls @wc -l /etvc##c/passwd
42 /etc/passwd
$ stty sane
$ exit
$

where /bin/sh is dash(1) on this Ubuntu system.

"Write permissions to the device file are required, so when a user logs in on a particular TTY, that user must become the owner of the device file." I think it's read permission that's required to alter a tty's settings. It did used to be write, in the very early days, but since write(1) and mesg(1) meant users could write to one another's terminals it also meant they could alter their settings. Much fun could be had with changing erase to `e' for a second and back again at random intervals whilst the user was trying to type. So it was switched to require read permission which only the owner of tty normally has. This can be seen in stdin of stty needing to be re-directed to specify the terminal, and not stdout, e.g. `stty -a </dev/pts/1'.

Flow control, e.g. ^S and ^Q, existed long before the signals for job control. IIRC, it was Berkeley that added all the ^Z stuff and related signals, it wasn't Bell Labs.

The Linux kernel doesn't bother to implement all of the normal control characters. Flush is one that's missing, IIRC, which is set with stty's `eol2'. It's a shame.

Cheers,
Ralph.

Quoting the article,

Note: When optimizing an antagon, all bits are to be moved as far to the left as possible. If an antagon ends in ...001 it will be optimized into ...010. Therefore, an optimized antagon always ends with a 0.

It seems less arbitrary if we modify the rule for optimization to take into account an extra, virtual position to the right of the rightmost digit. This position would be worth zero (extrapolating the Fibonacci series, as 1 = 1 + 0), and assumed during optimization to contain a one.

Ah, On first reading I took the "it will" to mean the preceding changes will cause this to happen, as opposed to an extra step required.

lft wrote:

It seems less arbitrary if we modify the rule for optimization to take into account an extra, virtual position to the right of the rightmost digit. This position would be worth zero (extrapolating the Fibonacci series, as 1 = 1 + 0), and assumed during optimization to contain a one.

Yes, I agree. That's the conclusion I came to overnight. All we need to do is ensure that it's the most significant of the ones column that's set if the other is clear, and placing a 1 in the zero column, only during optimisation, is the easy way to do that.

$ opt() { sed 's/$/1/; :l; s/\(.*\)011/\1100/; tl; s/.$//' "$@"; }
$ echo 100000 011000 010110 010101 | tr \ \\012 | opt | uniq -c

Congratulations on a brilliant project!

Are you available for gigs in the UK? I help run a chip-tune themed night, and having a live soundtrack (we already have live Gameboy performances) would be incredible!

Please get in touch if you'd be interested:

Linkstar, pagerank peddlers?

Interesting. I've been using Adbrite (because Google Adsense does not work on https pages), but I never thought about nofollow attributes. I just checked, and they don't place rel="nofollow" attributes on their links either.

However, I'm not sure that's relevant in this case, since Adbrite ads are included dynamically on the client side, so a search engine bot never sees them. Is that not also the case with Linkstar, or do they want you to insert ads server-side?

Where's the man's hat?

Good question. I find the Internet is to blame for shortening my attention span and making it harder to concentrate on one thing. Gone are the days of reading a book in one sitting. Still, nothing a bit of self-discipline wouldn't fix, I suppose?

You are a genius. Normally, engineers would enhanced/ redefined the analogue organ. But you transformed an analogue organ to a synthesizer (dual synthesizer)and it is a backward design. It is incredible.

"Håkan, organ donor." ..... (speechless)....

I LOL'd at that as well- brilliantly deadpan (or, at least, that's how I read it!)

And this project is amazing. Thanks for the incredibly thorough breakdown, the inner workings of the original organ are fascinating (yes, particularly the photosensor-based pedal).

Incredible job! Thanks for sharing!

I try to divide my days into different sections; Mornings are for reading RSS feeds and my list of URLs, at work I can usually find the time to check email and IRC, and when I get home I try to avoid the internet altogether, except when I need to look up something specific. I obviously don't have a TV set. Then, of course, any self-imposed scheme like this can be disregarded as needed on a day to day basis, but it generally pays off to stick to it.
