I am wondering if we should start a WikiProject for Electronics. — Omegatron 00:20, 15 September 2005 (UTC)
How difficult was it to make Image:Star-Triangle transformation.png? I've experimented with dia and couldn't get anything useful out of it.
We have SVG support now, so we can theoretically make high-quality schematics that others can then edit. I tried drawing an example in Inkscape:
The fonts look different, of course. :-\ Also I drew each component by hand, which is a pain. Now they're in groups that can be copied and pasted, but Inkscape's not really meant for blocks-connected-by-wires-on-a-grid type drawing. Any ideas? — Omegatron 00:36, 15 September 2005 (UTC)
Hey, I read the two things you wrote me on my talkpage. I absolutely agree about creating a a WikiProject for Electronics, it would be useful for a sort of unification of the style and planning of the further work.
The main problems are: 1) decide a common style and create some templates, but we can start from an existing stub template 2) we'll have to suggest a common programme to draw circuits, to export in SVG.
I have few ideas, if you agree I'll start writing the article about the wikiproject now, then we'll discuss all the other improvements.
About using Dia for drawing: I tried using it once, but as you can see I made all the other circuits after that with Xcircuit. Dia has some strong limitations: most of the devices are not in the library (I drew only resistors with it!) and you can't rotate objects. In my Image:Star-Triangle transformation.png I made a draft with Dia and I postprocessed it with Gimp (rotating and connecting the resistors, etc.). Drawing something more complicated would be crazy.
I took a look at the Inkscape you told me about: it's the most promising programme, but there are few issues. There is a lot to say about this topic, and if you agree I will write properly on the page of the future wikiproject about electronics. I thought about contacting the developers of the programme, too: wikipedia is important and to be a programme suggested by wikipedia could be important for them, so I think they won't mind adding a few features for us, hopefully with our help.

Hi, I did it: I started a Wikiproject about electronics. The home page is here. Take a look and tell me what you think about it: after that we'll start diffusing it :-) Alessio Damato 18:53, 20 September 2005 (UTC)
Hi, I noticed that you added SVG versions of the plots in Bessel function. In principle, this seems like a good idea to me. However, I have a couple of requests/suggestions.
First, do not use color as the sole way to distinguish between curves. This is problematic for the color blind, and for monochrome display devices. One way to fix this is to also use dashed/dotted lines, etcetera, an even better way is:
Second, it is much better to attach labels to curves directly (see the original versions of the Bessel plots, for example), rather than having a second "legend" box. This avoids an indirection, where the user has to look back and forth between a "key" and the data rather than just at the data; see e.g. Tufte, The Visual Display of Quantitative Information.
Third, I notice that your y-axis label for Image:BesselJ plot.svg falls on top of the tick numbering; please be careful of small glitches like this.
(Unfortunately, gnuplot is not the most flexible plotting tool in the world.)

Hi,
Looks like good work on the bessel functions, thanks ! linas 23:10, 12 October 2005 (UTC)
Hi there. Sorry to be slow to get back to you.
I made the timing diagrams from the command line and then spent a while tweaking the export options regarding exporting before the final image was useful. The labelling of it I did all in Powerpoint (I think I exported a .eps version from Matlab) since the labelling feature in Matlab is a bit poor and fiddly to use. So I don't have the code I used, although with some legwork I guess I could reconstruct it. I think I'd prefer not to, though, since the .png files we already have are ok enough. The constellation diagrams I made entirely in Powerpoint; Matlab can do that (I believe the Comms toolbox has specific functions for it), but I didn't like the output as much as what I could get in Powerpoint. Using Powerpoint also avoided the need to write any code at all — I just positioned things using the default snap-to-grid things. Unfortunately, neither Matlab nor Powerpoint can export in .svg so I had to settle for .png -Splashtalk 01:19, 23 October 2005 (UTC)
Hi. I noticed the really nice picture Image:Rome the sacred area of largo argentina 20050922.jpg. The problem of that image is that you states in its description that the image is released in public domain, but than you added GFDL and CC-by-sa tags. Please, choose either public domain or the GFDL/CC licenses, and correct the page.--Panairjdde 11:10, 21 November 2005 (UTC)
Hi I was interested in your comments on Edsanville's page re: Gnuplot and SVG. Do you know of a reference that explains (i.e. teaches) how to make images and animations with the Gnuplot and SVG? Sholto Maud 04:44, 19 December 2005 (UTC)
Hi Alessio, thanks for your comments! I actually wasn't aware that SVG images could be uploaded, so I converted it to PNG first. I've uploaded the file now to Image:Single-phase transformer.svg on the Commons. It appears that some of the formatting hasn't come across quite right: the flux symbol for example has disappeared, and the subscripts on the number of turns look a bit funny. I guess these can be sorted with a little work and I can reload the file. Is there a particular reason that SVG should be preferred over PNG? regards, --BillC 20:15, 19 December 2005 (UTC)
PS: Don't forget to sign my guestbook! :-)
Please correct the labels on Image:BesselI plot.svg, which incorrectly say "J_n" instead of "I_n". thanks! (While you're at it, proper subscripts instead of underscores, and a larger font on the labels, would be nice.) —Steven G. Johnson 03:14, 25 January 2006 (UTC)
I fixed the labels myself, never mind. —Steven G. Johnson 20:10, 14 March 2006 (UTC)
It has been suggested by User:BrianSmithson that the Beer and brewery categories should be renamed. The proposal has been supported by User:Syrthiss, and supported and expanded by myself. The notion is that the regional categories should follow the format of "Beer and breweries in Africa" /Europe/Asia/North America/South America/Oceania. "Brewers and breweries" could also be renamed "Beer and breweries by region". And all the countries should also be renamed (and merged if needed) as, for example, "Beer and breweries of Germany", "Beer and breweries of Britain", "Beer and breweries of Poland". The word in each case would be beer rather than beers to allow for general articles on beer culture in each region as well as individual beers.

Hi, I noticed you posted Image:Dandelion clock dft dct.png. Thanks! It might be clearer if you didn't center the FFT spectrum, however. (Note also that you can use the fftshift command instead of using the (-1)^(i+j) trick, which only works for even sizes.)

I like the new SVG images. Can you make one for a full-wave rectifier, too? — Omegatron 17:41, 15 May 2006 (UTC)
Alejo2083, I would like to participate in writing the page about one of the most interesting electronic circuits -- Negative impedance converter (as I can see, you have begun creating this page). I have been trying to reveal the secret of this "mystic" circuit from many years. Now, I have the feeling that I have managed to grasp the basic idea behind it; so, I would like to share my penetration with Wikipedia audience.
According to Wikipedia conventions, I have first exposed my suggestion on Talk:Negative impedance converter. I would be glad, if you and other Wikipedians who love exotic circuits join this discussion.
I have also tried to resume the discussion about Current source and the dual Voltage source −- see Talk:Current_source#New_structure. Circuit-fantasist 18:00, 7 July 2006 (UTC)

Hi Alessio,
Yeah I would be very interested in contributing, give me a couple of days for me to get some uploading out of my system (I've been restraining myself for like 2 months now with exams and stuff)! Then I'll have a shot at writing something. --Fir0002 04:24, 20 November 2006 (UTC)

Hi, Alejo2083!
I just read your new article on solitons, and I'm impressed. It's an excellent article. Thank you for putting so much time and effort into it.
I did notice some little things about the English idiom and style. I'm guessing that English is your second (third?) language. So I just wanted to let you know I'll probably change a few words here and there, and maybe alter some punctuation, in the next day or two. It's no reflection on you ... you clearly know your stuff. I'm just pretty picky about English idiom.
Thanks again for writing such a wonderful article on an interesting topic! DavidCBryant 13:26, 14 February 2007 (UTC)
Hi, thanks a lot for the great soliton (optics) article! You write "The higher frequency components will propagate a little bit faster than the lower frequencies, thus arriving before at the end of the fiber." Isn't it true that red light is faster than blue light in glass?
Also, since you seem to be good with graphics, I was wondering if you could create a picture for soliton? Maybe an animated picture, a soliton moving from left to right. Or even two solitons meeting and passing through each other. Cheers, AxelBoldt 18:57, 11 March 2007 (UTC)

Hi,
Looking at the edit logs of the article on the Fourier Transform, I see that you were the person that added what is now called Fourier Transform pair 311 on 3 May 2006. It is in the distributions section. If I am not mistaken is a square integrable function. Why then is this Fourier Transform pair in the distribution section?

Hello Alessio.
At the following URLs

http://wiki.w2n.net/pictures/Trigonometric_functions.svg
(and probably others)
there is your image showing plots of the six common trigonometric functions.
In this image the X axis is marked in multiples of 1 (from -4 to 4).
These positions do not correspond to the significant X values in the functions so, if possible, please could you replace the X axis markers with
multiples of π/2 (pi/2) from -3π/2 (-3pi/2) to 3π/2 (3pi/2)
or even
multiples of π/4 (pi/4) from -3π/2 (-3pi/2) to 3π/2 (3pi/2)
and note them as being in Radians.
It might also be worthwhile also showing the values in degrees in multiples of 90 or 45 from -270 to 270.

A discussion has been opened on changes that have been made to the existing Beer category system. The changes reverse the decision made by the Project in April 2006. The changes were based on agreement by only two people, and by a discussion that took place outside the Beer Project. There may be some merit in the changes, and to prevent future conflict it is important that there is some discussion of the matter.

Hi, I am writing to you because you have listed yourself as a member of the Electronics WikiProject. Sadly, this project is pretty dead, but I propose to resuscitate it with a collaboration. The idea is to have a concerted effort on improving one article per month, hopefully to GA or FA status and nominate the very best of them for the front page. I have prepared a page to control this process at Wikipedia:WikiProject Electronics/Collaboration (actually, I mostly shamelessly stole it from Wikipedia:WikiProject Mammals where a collaboration of this sort was succesfully run). There you can make nominations for articles for collaboration or comment on the nominations of others.
If you want to take part you might like to place this template ((WikiProject Electronics Collaboration))
on your userpage which will give you a link to the current collaboration. If you are no longer interested in Wikiproject Electronics, please remove yourself from the members list, which is now at Wikipedia:WikiProject Electronics/Members

Hi Alessio,
I noticed you put the differentiator filter edit in the DTFT page. Did you get this from a book? I see you have a background in EE and sound. I ask because this was published in a recent paper (2008) but the authors were not aware it was on wikipedia or anywhere for that matter.

Hi Alessio, Thanks for a useful book on LaTeX. Is there a way to add numbers to equations formatted using LaTeX but shown in wikipedia? Am trying to convert a book (http://en.wikibooks.org/wiki/Parallel_Spectral_Numerical_Methods) from LaTeX to wiki format, but with the default extensions on wikibooks it is not clear how to get automatic equation links and equation numbering.

Thanks that is very helpful. Mathjax does some of this, and updates equation numbers automatically but creating links is not yet quite as friendly or quite as well documented. Mathjax is not yet implemented as default though. Some discussion on this is here:
