== Maximum Power Point Trackers Mar 12, 2012 ==
 
I looked around on wind turbine boards and did not find a MPPT tracker that would suit my need.
 
So I designed my own and I got the circuit board in last week. I saw your website and
 
this other most recent MPPT discussion, after I started my design:
 
http://www.vawts.net/t45173979/mppt-specs/
 
http://www.vawts.net/t47246927/steves-controller-working-wow/
 
I had some questions and comments in that long thread.
 
 
Mine is based on an IC with some microprocessor control: http://www.linear.com/product/LTC3703
 
I hope you don't mind if I post it under yours if mine works.
 
It is a boost MPPT. Steve did a buck MPPT, which won't work for my generator.
 
I have not studied your circuit closely yet.  I read that you are thinking surface mount parts
 
are not liked by hobbiests. I am just getting into them. This is my first circuit with them.
 
I have a hunch that I will grow to like them because there are no holes to drill and smaller
 
boards are nice. Let's see if I have good soldering technique. I bought an air heat gun too.
 
 
I just read your other site and posted it on VAWTS.net. I think it is a very interesting idea
 
since it can do buck or boost.

Thank you for giving me the link to the vawts.net discussion.
 
Fascinating.
 
Feel free to post your design on [[maximum power point tracker]] if you don't want to create a new page for it.
 
I think that [http://thesolarpowerexpert.com/a-diy-dual-voltage-converter-turning-the-solar-charge-controller-circuit-on-its-head/ Chris at thesolarpowerexpert] is pretty insightful,
 
so I am flattered that you seem to confuse him with me.
 
(I'm a little confused myself as to whether that Chris
 
is the same as the Chris who developed [http://www.freewebs.com/acselectronics/buildppt.html A Solar Panel Power Point Tracker]).
 
--[[User:DavidCary|DavidCary]] 01:14, 14 March 2012 (UTC)
 
 
Haha. I skimmed through too many links to links to links. I am still confused as I write this. I'll sort it out later.

== How to add schematic file upload to this website Feb 19, May 8, 2012 ==
 
 
History diff explains a lot about why this could work. The interface concept of editing
 
everywhere was so bizarre, I didn't know what to do. I got bold after I figured the place is a
 
ghost town when a note I left went unanswered for a week. This site comes up often in my
 
searches. I just could not understand it. I get it now, sort of.
 
 
How do I upload a .sch file?  The picture types limit is unreasonable on an electronics board.
 
 
Regards, Definitionofis
 
--[[User:Definitionofis|Definitionofis]] 15:42, 19 February 2012 (UTC)
 
 
Yes, I agree that the OpenCircuits.com wiki really *should* support uploading original, editable schematics files -- not just images that *look* like schematics but are uneditable.
 
Alas, I'm a little fuzzy on how to enable that functionality.
 
--[[User:DavidCary|DavidCary]] 01:14, 14 March 2012 (UTC)
 
 
MAY 8, 2012 Definitionofis:
 
I found instructions for adding more file upload extension types, other than just png and jpg.
 
(By the way, I tried to upload images just now and I got an error message. I will skip it for now. I am out of time.)
 
I need .sch .brd .net .lib .emp .mod for KiCAD.
 
 
Here are the instructions: [http://www.mediawiki.org/wiki/Manual:Configuring_file_uploads]
 
and an excerpt from the bottom of that page:
 
 
-----------------------
 
Configuring file types
 
 
You can add $wgFileExtensions in LocalSettings.php to allow uploads of other desired file types. For example, you can change the $wgFileExtensions line to look something like
 
 
$wgFileExtensions = array('png','gif','jpg','jpeg','doc','xls','mpp','pdf','ppt','tiff','bmp','docx', 'xlsx', 'pptx','ps','odt','ods','odp','odg');
 
 
or
 
 
$wgFileExtensions = array_merge($wgFileExtensions, array('doc', 'xls', 'mpp', 'pdf','ppt','xlsx','jpg','tiff','odt','odg','ods','odp'));
 
 
or
 
 
# Add new types to the existing list from DefaultSettings.php
 
$wgFileExtensions[] = 'doc';
 
$wgFileExtensions[] = 'xls';
 
$wgFileExtensions[] = 'pdf';
 
$wgFileExtensions[] = 'mpp';
 
$wgFileExtensions[] = 'odt';
 
$wgFileExtensions[] = 'ods';
 
 
However, certain file extensions are blacklisted ($wgFileBlacklist) and cannot be uploaded even if added to $wgFileExtensions. To upload files with blacklisted extensions, you must modify the blacklist. For instance, to allow users to upload executables:
 
 
$wgFileExtensions[] = 'exe';
 
$wgFileBlacklist = array_diff( $wgFileBlacklist, array ('exe') );
 
 
==no captcha?==
 
Could you please let me bypass the captchas? I would like to categorize approx. 200 articles, but it would be very tedious with the captcha. (PS: there is also some answer on my disc. page.) --[[User:Glenndk|Glenndk]] 17:22, 22 December 2011 (UTC)

Note new page on hacker spaces off main page, also thinking of swapping out the old component page, see link to new one at top of old page.  Let me know what you think if you have an opinion on the changes.
 
-- russ_hensel
 
 
A place where people do cool and amazing things sounds wonderful -- I'd like to support that.
 
 
But what would I write on the [[HackerSpaces]] page -- other than "Go see http://hackerspaces.org/ ", which is already mentioned on that page -- that wouldn't be better posted on that other wiki?

I have been thinking about how to get more traffic at open circuits.  So far:
 
 
*Post links to it on forums, these are usually on topic for the forum, not just ads.
 
*Started a sub wiki for SourceBoost C ( much of which is just a collection of stuff I was doing here anyway )  If this seems to commercial, let me know and we can see if there is a better way to do it.  I think it fits the site well however.
 
*When I link to sites now I often send an email letting them know and inviting them to contribute, not too much has come of this yet, but more time will tell.
 
 
*Should we consider adding the site to some web rings?  If we think this is a good idea what process should we use to discuss and keep the process under control.

== from joshua w. ==
 
The pceeg project has become a alpha release now. I now have eagle cad files schematics and boards for all three boards.
 
I have the pcb from sparkfun in my hand.
 
I will be ordering parts for the microcontroler printed circuit board this weekend to test it out.
 
Take a look at it it has changed a lot.
 
I look forward to your comments I would like help on this project.

== Supporting More Image Type ==
 
 
Currently open circuit supports png, gif, jpg, jpeg formats. Is it possible to support svg as well? --[[User:Tcwden|Tcwden]] 04:51, 23 February 2009 (UTC)
 
 
: I see that the Mediawiki software we use can support SVG with a bit of setup. http://www.mediawiki.org/wiki/SVG . --[[User:DavidCary|DavidCary]] 05:15, 23 February 2009 (UTC)
 
 
Thank you. I think SVG is useful graphics format for our discussion because, being in vector format, it is more convenient to edit and resize if needed.--[[User:Tcwden|Tcwden]] 01:40, 25 February 2009 (UTC)
 
 
== Baudline Free Software ==
 
 
On the Open Circuits [[oscilloscope]] page,
 
I don't understand why you took "baudline" out of the "open source" section.
 
Anyone can buy the source code with a "GPL source code license" at
 
http://www.baudline.com/source_code.html
 
.
 
You have read what our [[Main Page]] says about "Selling Free Software", right?
 
GPL is open source, right?
 
--[[User:DavidCary|DavidCary]] 03:16, 26 October 2009 (UTC)
 
 
Sorry, I only read the license for the free download. Come to think of it, however, "The source code is expensive and it is intended for qualified corporate or institutional buyers" seems like a big deterrent to any hobbyist getting their hands on the source any time soon. While the software is technically GPL, it seems almost pointless to list it as such. I'm probably not going to modify it more than I've done though (listed it twice).
 
 
[[User:Cov|Cov]] 20:36, 26 October 2009 (UTC)
 
 
: I personally am more interested in the the "open-source freedom vs closed source" distinction than in the "zero money download vs pay money to download" distinction.
 
: Alas, as [http://www.gnu.org/philosophy/free-software-for-freedom.html Richard M. Stallman pointed out], there seems to be confusion around the word "free".
 
 
: Yes, "source code is expensive" is a big deterrent to hobbyists.
 
: Perhaps putting things in the technically correct category is "pointless". But if so, why bother using a category if it's not useful to our readers?
 
: The "PC Oscilloscopes" category looks even less useful, since (currently) it appears that every o'scope on entire the [[oscilloscope]] page seems to be in that category. (Is that just a formatting glitch?)
 
: Would different categories -- or no categories at all -- be more useful to our readers? --[[User:DavidCary|DavidCary]] 16:17, 7 November 2009 (UTC)
 
 
:: * I too care more about libre than gratis.
 
:: * I don't think I really put my finger on why it seemed wrongly categorized before but to me it's confusing to link to a piece of software's homepage, where the only downloadable version is non-free and say it is free software without reservation. The way it is now clears that up I think.
 
:: * Oops, I must have not been paying attention to the level of <code>=heading=</code> that was being used. Fixed the category mix-up.
 
 
:: [[User:Cov|Cov]] 21:10, 14 December 2009 (UTC)
 
 
::: Great. Thank you for fixing it up so [[oscilloscope]] is (as far as I can tell) both accurate and useful to our readers. --[[User:DavidCary|DavidCary]] 05:18, 17 December 2009 (UTC)
 
 
:::: Hi. I don't agree. I'm a simple free software user. The [[oscilloscope]] page is not accurate in my opinion. I read your discussion, studied the [http://www.baudline.com baudline web site], studied the pages on gnu.org web site about [http://www.gnu.org/philosophy/free-sw.html free software] and specificaly [http://www.gnu.org/philosophy/selling.html Selling Free Software].
 
:::: I quote here, from the latter page, the two first paragraphs of the last section titled "High or low fees, and the GNU GPL" on this page in the english version ("Updated: $Date: 2012/06/10 08:06:17") : "Except for one special situation, the GNU General Public License (GNU GPL) has no requirements about how much you can charge for distributing a copy of free software. You can charge nothing, a penny, a dollar, or a billion dollars. It's up to you, and the marketplace, so don't complain to us if nobody wants to pay a billion dollars for a copy. The one exception is in the case where binaries are distributed without the corresponding complete source code. Those who do this are required by the GNU GPL to provide source code on subsequent request. Without a limit on the fee for the source code, they would be able set a fee too large for anyone to pay—such as a billion dollars—and thus pretend to release source code while in truth concealing it. So in this case we have to limit the fee for source in order to ensure the user's freedom. In ordinary situations, however, there is no such justification for limiting distribution fees, so we do not limit them".
 
:::: in the case of the software called "baudline", the source code is not available for everyone because of its price (unknown but "expensive") AND because of the restriction to those being acceptable as clients of the source code, as we can read on the [http://www.baudline.com/source_code.html baudline page titled "source code"] : "it is intended for qualified corporate or institutional buyers".
 
:::: I searched for web sites redistributing the boadline source code and found nothing.
 
:::: Thus, the user's freedom of being able to read the source code is not given, as far as I can see, and I condider that the pretention to apply the GPL licence is abusive.
 
:::: Thank you to let me modify this page and express my opinion.
 
 
== David: An Interesting Comment you made ==
 
 
If you please to continue…
 
 
"I agree that you're not going to get worthwhile amounts of power out of this all by itself. But it's a bit misleading to say "nothing" when the graph clearly is non-zero with "node 4 grounded" -- it looks like a voltage doubler. – davidcary Dec 30 '10 at 17:02"
 
 
You made this comment about a circuit that has been dubbed as being "BOGUS". I thought it to be very interesting, as I have recently built and tested several of the modules. In the test I have made, I find the circuit to be  an anomaly. IT is not normal. it reacts differently in direct sunlight than in shade. It reacts to sound, and pressure. All of the scale of said reactions are very, very small, however, readable, and most interestingly reproducible. it also reads a .02 Milli-amps on the voltmeter. Just sitting there.
 
 
I found it interesting that your comment supports the theory that the circuit needs to be connected to a very large load, or at least a very "active resistance" to affect and or allow a flow of current.
 
 
Please continue with this talk if you are able. I am very concerned about what we may discover. thank you

You said this 1.5 years ago.
 
I just saw it a week ago. haha
 
 
You:
 
    "Thank you for drawing this problem to my attention.
 
    I edited the "$wgFileExtensions" array to allow schematic file extensions.
 
    Please let me know -- did that fix it?

talk page or a private message using my talk page's "E-mail this

Me: User_talk:Definitionofis says:
 
 
I tried to find the schematic but then I see KiCAD has changed file formats.
 
I will let you know after I upgrade the schematic and the board layout file.
 
I hope you added both extensions; schematic and board layout. I forget how KiCAD works. I think it has two file extensions.
 
 
(Edit, Apr 12,2016: I see we discussed all of these: ".sch .brd .net .lib .emp .mod for KiCAD.". So I am sure you added them all and I will upload them all for my schematic, soon, and see if it works.)
 
 
You said:
 
    "Apparently over the years (!) that we've been having this conversation,
 
KiCAD added a couple more file extensions, so I edited the
 
$wgFileExtensions array to allow them as well. --DavidCary (talk) 15:26,

Me, Aug 5, 2016, User_talk:Definitionofis says:
 
I added a new project and successfully uploaded .sch and .kicad_pcb files. yay! Thank-you. I will update all my other projects with schematics and pcb boards now that I have learned the KiCAD version 4.02 software changes.
