User:FSHL[edit]

I see you already argued with him, so maybe you could take a look here Commons:Deletion requests/Image:Su-37-Draft.svg. He already betray himself: I could upload then but I'll not. I've my justified reasons for limiting the publication that I'll not explain in public – sorry!. It is clear that he couldnt upload the, because they would all breach the copyright. I would call him a Spinner;)--D.W. 20:38, 7 July 2007 (UTC)

Aeroplane 3-veiws[edit]

Hi. Thanks for starting the discussion over whether these drawings are copyvios. It's great to finally have a proper discussion about all these potential traces from FSHL. This question is related to that, but I don't really want to put it there, as it isn't the issue in hand, and will just complicate things.

If I get a line drawing from the internet/book.etc., can I do a proper trace of it (like Image:B-52_3-view.svg, which was traced from a [NASA source], so PD is given) and put it under a free licence? This example was done by laying down paths by hand on top of a raster background, and no automatic processes like Inkscape auto-trace were used on the original image. If I can, then surely the best option in the Su-37 debate is to gradually replace them with decent traces, which are more useful anyway as they are not blurry.

Thanks, Inductiveload 14:05, 2 August 2007 (UTC)

If the source is PD the trace can be with any license. I really want to use {{PD-USGov}} rather than {{PD-ineligible}}. -- Cat chi? 14:09, 2 August 2007 (UTC)
Sorry, my question wasn't that clear. I meant to ask what if the source isn't PD? For example from a webpage or book. Inductiveload 14:05, 2 August 2007 (UTC)
Then we enter the wonderful world of copyright discussions. PD-Gov would be problem free by default. I am more than certain NASA has these technical drawings somewhere on their site. -- Cat chi? 15:18, 2 August 2007 (UTC)

CANDU reactor[edit]

I updated the labels and wiki links of your CANDU schematic. It is certainly QI. Feel free to nominate it. Please drop me a line to be sure I don't miss it.

I would not go for FP though. IMHO, FP would require to add secondary/tertiary circuitry interconnected with the electrical grid to give the full picture.

Permission Request[edit]

Hi, please contact me at dean at fourwalledcubicle dot com, re: permission to use one of your images.

Image latex?[edit]

Hey,

I had a question how did you make this image? http://commons.wikimedia.org/wiki/Image:XCubed_Fourier_Series_Approximation_n%3D7%2C15.svg

Did you do with LaTeX!?! Because it's has nearly the same style.the preceding unsigned comment was added by Wouser (talk • contribs)

This particular image was not made with LaTeX. The font is DejaVu Serif (i chose it because it looks quite similar to Computer Modern, the LaTeX font), the grid and labels were drawn in Inkscape, and the lines were plotted in Mathematica and imported to Inkscape. Some drawings which require more complex formulae have used the Inkscape LaTeX plugin, which allows you to place a formula directly into an SVG as a path. However, for that to work, you have to have LaTeX installed.
If you have a specific graph in mind, tell me and I wil be happy to draw it for you in this style. Inductiveload 13:22, 5 April 2008 (UTC)
Thank you very much for your reply. Well I don't need a graph in this style at the moment but I really think it's a very nice plot so I thought it would be very handy to know how you did it regarding to the future when I need stuff like this. When I need such a graph in the future and I fail myself at creating such nice one may I contact you then? Regards --Wouser 20:21, 5 April 2008 (UTC)
If you need to drop nice-looking LaTeX friendly graphics into a LaTeX document (rather than a web page), I think you'll have nicer results if you use w:PSTricks or (if you must) w:PGF/TikZ. You can insert both directly into a LaTeX document (no GUI required!), and w:PSTricks has math support that allows it to draw functions for you. —TedPavlic (talk) 14:40, 18 February 2009 (UTC)
Of course. Feel free to ask at any time, although if I am away, it may take a long time to get back to you. Remember that SVGs are easily edited with Inkscape, so you can take one of the current ones apart and make it yourself if needed. Nearly all my work is in the public domain, so there are no copyright issues at all. Inductiveload 19:57, 6 April 2008 (UTC)

License[edit]

Hey. I don't think your license on Image:EM Spectrum Properties edit.svg is correct. You released it into the Public domain, but you used Image:P _biology.svg which is GFDLed. I'm no lawyer, but I believe that means your derivative works has to be GFDLed too. Cheers! --24.5.195.85 16:34, 17 April 2008 (UTC)

You're quite right. Image:EM Spectrum Properties.svg was the first version of this, and that was GFDL'd under that argument, but I must have forgotten to change this one when I uploaded it as "Pd-self" is my default mode. I've changed it now. Inductiveload 14:11, 20 April 2008 (UTC)

Mupad[edit]

Hi . Thx for great images. Exponential functions images are made with Mupad. It hasn't free licence ( if I'm not wrong). Is it possible to do it with opensource programs ( like Maxima ) ? --Adam majewski 07:46, 1 May 2008 (UTC)

Not as far as I know. I use it from university. I don't know what free software there is to be honest and I have no idea how good it is. With the exception of Inkscape, which I like much much more than Illustrator. If you were looking to buy something, I'd recommend Mathematica (if you're a student it's about £60 - not quite as steep as learning curve!). Check out Airy function for more recent Mathematica plots.Cheers, Inductiveload 12:00, 1 May 2008 (UTC)

CANDU heavy water flow v. pump.[edit]

Regarding the CANDU reactor schematic, the heavy water flow seems wrong to me. The heavy water pump should be pumping cool towards hot and not the hot heavy water coming out of the reactor. (This is my opinion, I don't actually know which way it flows, but it would make sense to pump the cooler water than the hot). It would also make sense that there are at least two separate pumps on both the primary and secondary loops.

Well, I made the SVG diagram (here for those interested), from a raster diagram (here). I'm not a nuclear design engineer, so I also don't know which way round it goes. To be honest, I don't think it really matters - the point is that the diagram shows a device for drawing the water around the system - the diagram is not designed to be a fully accurate drawing of a full nuclear power plant, just a schematic representation of the concept. Maybe it works better that way for some reason. You should ask emoscopes, the original author of the PNG. If you find out it is indeed supposed to be that way around, could you drop a note here, as I'd be interested to know why. Inductiveload 21:22, 23 May 2008 (UTC)

Problem with Image:Fresnel Integral Contour.svg[edit]

Allow me to draw your attention to a problem with Image:Fresnel Integral Contour.svg, signalled by an anonymous user at en:Talk:Fresnel integral#Evaluation: the equation for the path γ3 should be: z = te^{i\pi/4}\,.

Nearby Stars[edit]

Thanks for publishing the sourcecode for your plot of the nearby stars! It was a great inspiration! I've adopted the code for Flash ActionScript and made a small application. Check it out here: [1]

I wrote a short article on it on my blog: [2]

  • No problem! I love it when people use my work either directly or indirectly. Thanks for telling me about it - your ActionScript looks fantastic - it's just a shame Commons doesn't support this kind of object due to licensing reasons.Inductiveload (talk) 02:19, 19 November 2008 (UTC)

Creating Circuit Diagrams[edit]

I was visiting the band-pass filter article on wikipedia and found your work on it, and I've been working on trying to get prettier documents in general, and making circuit diagrams has always been a crux concerning reports that I have written, and I was just wondering what program you use and where you get such properly proportioned circuit elements. Thanks! —Preceding unsigned comment added by Bmtran (talk • contribs) Nov 18, 2008 (UTC)

  • Hi, I use Inkscape and the circuit elements are made by me. Feel free to copy them out of the diagrams, as they are all public domain. Generally I find that a line width of 2px for all wires and 3px for outlines of components works well. Also, I always take great care to make everything (or as much as possible) in my diagrams lie on the pixel grid to aleviate anti-aliasing problems. Check out the Circuit Theory Wikibook for some more, similar diagrams. Also if you ever need a diagram, ask me and I will be happy to make it and upload it here. Inductiveload (talk) 02:15, 19 November 2008 (UTC)

I really like your ark working in drawing circuit diagrams. I saw a png file in the Circuit Theory book it contained several circuit components it wasn't helpful because I need them in svg. I was wondering if you could upload the symbols you have so far so we can use them to draw nice diagrams like yours. Thanks a lot! Keep up the good work! --Bazzoola (talk) 07:43, 11 February 2009 (UTC)


Tip: Categorizing images[edit]

Afrikaans | العربية | беларуская (тарашкевіца)‎ | català | čeština | dansk | Deutsch | Deutsch (Sie-Form)‎ | Ελληνικά | English | Esperanto | español | فارسی | suomi | français | galego | עברית | magyar | íslenska | italiano | 日本語 | ქართული | 한국어 | македонски | മലയാളം | Plattdüütsch | Nederlands | norsk bokmål | polski | português | română | русский | slovenčina | slovenščina | српски / srpski | svenska | українська | Tiếng Việt | 中文 | 中文(简体)‎ | 中文(繁體)‎ | +/−


Hello, Inductiveload!

Tip: Add categories to your images

Thanks a lot for contributing to the Wikimedia Commons! Here's a tip to make your uploads more useful: Why not add some categories to describe them? This will help more people to find and use them.

Here's how:

1) If you're using the UploadWizard, you can add categories to each file when you describe it. Just click "more options" for the file and add the categories which make sense:

Uploadwizard-categories.png

2) You can also pick the file from your list of uploads, edit the file description page, and manually add the category code at the end of the page.

[[Category:Category name]]

For example, if you are uploading a diagram showing the orbits of comets, you add the following code:

[[Category:Astronomical diagrams]]
[[Category:Comets]]

This will make the diagram show up in the categories "Astronomical diagrams" and "Comets".

When picking categories, try to choose a specific category ("Astronomical diagrams") over a generic one ("Illustrations"). Pro-tip: The CommonSense tool can help you find the best category for your image.

Thanks again for your uploads! More information about categorization can be found in Commons:Categories, and don't hesitate to leave a note on the help desk.

Polarization diagrams[edit]

Just wanted to say thanks for the diagrams of the different forms of polarization in (x,y,t). I managed to get through E&M and optics without having a clear mental picture of how circular and elliptical polarization actually happened, and you diagrams helped me get a much better understanding of what's going on.

Klein's bottle.[edit]

Hi InductiveLoad!

I have seen you made some contributions to Klein's bottle page and I would like to know if it was you who drew it.

I have some doubts in the Klein's bottle parametrization. It seems to me that g(u) becomes zero when u=0.

This makes x(u,v) and z(u,v) have a zero divisor in their formulae.—Preceding unsigned comment added by Eviruena (talk • contribs) 18:04, 28 January 2009 (UTC)

Hi Eviruena, I just drew the image from the existing parametrisation. You'd have to ask on the Klein bottle talk page (as I see you have already). If you find it is incorrect, please tell me, and I'd be happy to fix the image. Inductiveload (talk) 23:02, 28 January 2009 (UTC)

Schmitt trigger fig is feeding back to wrong input[edit]

The new Schmitt trigger fig (from w:Operational amplifier applications):

Op-Amp Schmitt Trigger.svg

presently is no different than an inverting linear amplifier. A Schmitt trigger uses positive feedback to drive the op-amp to a rail. The inverting (-) and non-inverting (+) inputs should be swapped on this fig. Thanks. —TedPavlic (talk) 22:56, 29 January 2009 (UTC)

Fixed - my bad. Good job in noticing! Inductiveload (talk) 22:43, 30 January 2009 (UTC)

Somalia map[edit]

Things are changing REALLY fast right now as various factions re-align with the Sharif election. There could be war between Hizbul Islaami and the ARS-TFG government within weeks, and it's still very unclear (perhaps even amongst themselves) who al-Shabab is going to support. Sharif may defuse the whole situation, who knows? --Ingoman (talk) 02:04, 4 February 2009 (UTC)

The whole situation looks like a nightmare, unfortunately. However, possibly an SVG map might make it easier for you to update when things change one way or another. I was going to message you earlier, but I forgot. It looks like you're putting in some serious graft just keeping that map up-to-date! If you look carefully at that map in Inkscape, you'll see that there is a layer to put a raster image so you can trace borders off it into SVG. You can also add as many or as few towns as you please! Inductiveload (talk) 02:45, 4 February 2009 (UTC)

Inverting and non-inverting Schmitt triggers (and relaxation oscillator)[edit]

First, thanks again for the great work making the circuits figs look consistent.

Second, on w:operational amplifier applications, there is an entry for Schmitt trigger that only includes a non-inverting Schmitt trigger. I've added text describing an inverting Schmitt trigger (it's identical, but input and ground are swapped). In a <!-- comment -->, I've made a note that an inverting Schmitt trigger would be nice to see in that same entry.

I've also added a section on implementing a relaxation oscillator with an operational amplifier. The conventional implementation uses an inverting Schmitt trigger combined with an RC network in the negative feedback path. I've included an SVG image from the main w:Relaxation oscillator page, but it would be nice if the SVG used on the w:operational amplifier applications page matched all the others there.

If you have time, it might be nice to add these things to your TODO list.

Thanks, again. —TedPavlic (talk) 14:46, 6 February 2009 (UTC)

Thanks! I did it, and put them both on w:operational amplifier applications. If there's ever any other circuit diagrams you want, just ask me, and I'll be more than happy to make them up for you. Inductiveload (talk) 21:32, 7 February 2009 (UTC)
