Wanneer je in het bezit bent van een een nieuwere telefoon wil je uiteraard vaak van het internet kunnen genieten. Thuis, of in de trein, op school of werk en op elk ander tijdstip dat je informatie wilt consumeren. Waarschijnlijk heb je zelf al een goede telefoon, of je hebt een los toestel via het internet besteld. Nu ben jij op zoek naar een sim only onbeperkt internet. Zodat je altijd gebruik kunt maken van alle functies van je je nieuwe aanwinst.<br/><br/>Een sim only is een abonnement zonder telefoon. Omdat je alleen een telefoonabonnement om te bellen, sms’en en te internetten besteld, is dit regelmatig veel minder duur. Deze abonnementsvorm wint dus ook sinds de laatste jaren aan populariteit. Bij een sim only zit je dus nergens aan vast.<br/>Een sim only is dus zeker geschikt voor jou. Je kunt heel makkelijk iedere week opzeggen, waardoor je aan niks vast zit. Kan je je nog voor de geest halen dat je een torenhoge telefoon betaling had omdat je toch een te kleine abonnement had afgesloten? Die periode is nu helemaal in het verleden! Je kunt zonder poespas iedere maand heel makkelijk jouw telefoonbundel aanpassen. Enorm gemakkelijk via je eigen portal op de website van de aanbieder. Ook als je veel gebruik maakt van mobiele diensten kun je dat op jouw persoonlijke pagina heel gemakkelijk aanpassen.<br/><br/>Natuurlijk zijn de sim only onbeperkt internet abonnementen van simyo ook uitermate geschikt om mee te bellen en sms’en. Je zit aangesloten op het sterkste netwerk van KPN. Een van de beste telefoonnetwerken van ons land. Je hebt de mogelijkheid om te kiezen uit verschillende telefoonbundels. Je kunt een keuze maken uit 120, 300 of 600 telefoonminuten/sms per maand. Voor grote bellers die echt heel veel gebruiken is er het 1000 belminuten sim only abonnement. Ook deze bundels zijn per maand aan te passen via jouw persoonlijke pagina op de website. Het advies is om voor minimaal 300 minuten per maand te gaan de geregeld bundel heet die. Waarschijnlijk zul je hieraan meer dan voldoende hebben, zodat je achteraf geen dure verassingen voor je kiezen. Om om te besparen kun jij ook gebruik gaan maken van de Whatsapp.<br/><br/>Doordat je nergens van afhankelijk bent, kun je altijd je eigen telefoon gaan gebruiken. Ben jij je smartphone beu? Dan kun jij met een sim only abonnement gewoon een andere smartphone kopen. Als je er zorgt voor draagt dat je nieuwe toestel geen simlock heeft, kun je gewoon je sim only kaart erin plaatsen. Zonder enkele moeilijkheden kun je weer genieten van internet, sms’en en internet op je mobiel. Je kunt via deze manier altijd de laatste mobieltjes tot je beschikking hebben. Geef jij helemaal niks om het nieuwste telefoonmodel? Dan kun je ook een ouder model kopen. Als deze niet voorzien is van internet, geef je dat door aan de website van simyo. Met een druk op de knop is je mobiele databundel afgemeld, dan hou je ook nog wat extra cash in je pocket! [http://telefoonabonnement.iloveblog.com/ lees meer info] <br/><br/>Welk abonnement je moet nemen bij simyo.nl is totaal afhankelijk van jouw eigen persoonlijke situatie. Ben jij iemand die veel belt? Dan kun je natuurlijk het beste een hoger abonnement afsluiten. De bundels zijn heel duidelijk opgemaakt. Jij krijgt bijvoorbeeld 700 minuten of smsjes. Dat houd in dat je 300 minuten per periode kunt verbellen. Stuur je een sms bericht? Dan kost jouw dat 1 belminuut. Erg transparant allemaal. Ons advies is de de geregeld belbundel. Dan krijg je 300 belminuten per maand. Voor de meeste mensen is dat voldoende.

Please help us to build this resource by submitting your descriptions, projects, instructions, techniques, board layouts, PCB footprints, and other documentation for electronics. This includes

ALL Electronics and Microcontroller circuits --npeducations

Meta Open Source

Meta Open Source: Not projects or information on projects, but stuff about Open Hardware Initiatives and the open source movement ( mostly hardware ) itself.

The Open Source Movement, typically covers Open Hardware, Open Firmware, and Open Software.

Open Hardware is similar to Free and Open Source Software.

The Open Firmware movement provides firmware (i.e.: micro-code specifically related to the subcoding of hardware devices) which you may also know as soft-IP or FPGA coding see Open Cores for more details.

Excellent examples of specific Open Hardware projects are listed on our Projects page. Discussions of more general open-hardware ideas are on a few pages here, such as open source electronics, Ideas, Meta Open Source, etc.

Just as many important pieces of open-source software are, in turn, used to develop software (including more open-source software), many important open-hardware devices are, in turn, used to develop hardware devices (including more open-hardware devices) -- such as Oscilloscope#Open Source Oscilloscopes. There's also a bit of crossover, in that software tools (many of them open-source software) are often used to develop open-source hardware.

Licenses

The most common "open hardware" licenses are the Creative Commons Licenses and the GNU General Public License. The GNU people wrote the the GPL FAQ to deal with common questions and misunderstandings of the GPL. The GNU people go on to say

"We encourage people who redistribute free software to charge as much as they wish or can. If this seems surprising to you, please read on." -- GNU: "Selling Free Software"

For example, Linksys makes money selling (among other things) their Linksys WRT54G series routers, which use Linux under the GPL license.

To understand what your entitlements and responsibilities are under the applicable license(s); each hardware, firmware and/or software piece you have either copied, modified, developed using tools provided or if you intend distributing your development, you MUST read each and every license, and be specifically aware that you may not mix such license(s) together unless they can co-exist under one umbrella license. For example you may modify, copy, enhance and distribute parts your project which are all under the same license e.g.: or .

Some people are working on licenses that are specifically designed for "open hardware". "Open Source Hardware (OSHW) Draft Definition 1.0"[1]. Wikipedia: "Open Hardware License"[2] mentions "CERN Open Hardware License"[3][4] and the "TAPR Open Hardware License"[5]. David L. Jones has a short video that discusses open-source hardware[6] and mentions several licenses, including the CERN Open Hardware Licence[7].

Help Us Make Open Circuits Better

What are we:

Looks like we are defining this by way of who contributes and what. I ( russ_hensel ) am a new member so may or may not have it right. This is what I think:

  • An introduction to Electronic theory, suitable for the hobbyist.
  • Guide to locating and using components and tools.
  • Details on how to build various projects.
  • Building some sense of community among builders.

There are two means of carrying this out:

  • Write material for the site or
  • Link to material you may have written or have located on the web. There is so much stuff on the web that lets not write it here unless it is at least somewhat unique.

What do you think, discuss it here if very general, else on the discussion page ( link at top of page ).
