The aim of this website is to make knowledge available for free.

This website complies with 501(c)(3) due to its educational and scientific character.

The calculations (in the Electronics) are done in javascript, so everybody may have a look at the source code to see how it is done. We tested a lot to assure that the tools work fine, but we can not guarantee that the results are valuable for any input.

If you build spacecrafts you may want to check the results with another tool :-)

This is a private website. We do not sell anything. Please don't ask. We may support you when having questions with one of our projects.

Some Files are restricted in use due to licences of the Software Manufacturer.

In no case do we allow the use of any information to build weapons and weapons related stuff.

This website is hosted on servers in Switzerland which are powered 100 % by renewable energy. This is water, sun and wind.

Excessive use of the internet may cause squared eyes, nervousness, irritability and depressions. Excessive use of our website may cause increase of knowledge and experience.

No animals were harmed whilst producing this website. Even the bugs have been removed very carefully.

We do not use cookies. Using cookies is a security risk introduced by goofy webmasters.

Your browser settings say "DNT = disabled". Therefore all external services which are suiteable to track your surfing habits are enabled. We use those services : FlagCounter™, Webutation™. DNT is the "Do Not Track Me" bit which can be set / reset in your browser settings.

As of 2023 all Google™ Maps have been replaced. YouTube™ Videos have been equipped with a two step permission script.

If you should send us an email using the email-form on our website, we can not guarantee, that the content remains secret on its way to our inbox.

And yes, we do have a look at the server statistics, but we do not report to NSA, nor do we give away data to anyone else. Just curious to see, which websites are popular and which are not.

Hiermit distanzieren wir uns vom Urteil des Landgerichts Hamburg. (12. Mai 1998) Wenn Sie annehmen, dass ein Gabelstapler Gabeln stapelt, dann sind Sie hier absolut falsch. Sämtliche Informationen wurden sorgfältig recherchiert. Weil das aber meist nachts passiert, können wir Fehler nicht ganz ausschliessen. Alle Links boten nützliche Informationen zum Zeitpunkt als wir sie anbrachten. Kurzum: wir haften für gar nichts.

This page is best viewed with my Browser. We gave up to find solutions to circumvent bugs in IE. It is much more satisfying to knit and tinker nice websites. For those people still using IE6 (in the year 2016 !!!!) : UPGRADE.

We declare that we do not collect any data of you.

... to see useful projects based on our basic calculators or ideas. It is motivating to see, that honourable homebrewers or webmasters indicate their source of inspiration.

Less motivating are useless datagrabbers who try to sell me my own content. Go away ! You are not welcome. We will have all contents removed from yumpu™ and similiar services. You mayst want to try this instead.

Thieves are not welcome.
