If there's one trend that the internet has fueled, it's the do-it-yourself trend.

It doesn't matter whether you want to bake bread, build a garden shed, upcycle something or weave a carpet: there are numerous instructions on the Internet for almost every project.

When it comes to repairing technical devices, I think https://de.ifixit.com/ is the best source.

Do you want to change the battery in an old iPod?

Does the pressure reducer make strange noises on the gas grill?

The washing machine refuses to spin?

You're guaranteed to find help at ifixit.com.

There are two central subsections on this website: In the “Instructions” section, you will find thousands of step-by-step instructions, sorted according to device categories, for example for replacing a battery in an iPod.

If, on the other hand, you have a more individual problem or one for which there are no instructions yet, you can – after prior registration – post your question in a forum and enter into an exchange with other members of this network community.

Of course it also works the other way around: If you are particularly familiar with one or the other area, you can enrich the website with your knowledge.

The "Teardowns" section is also really worth seeing: Here you can watch from a safe distance how technical devices are dismantled into their individual parts.

A regularly updated blog completes this extremely helpful and practical website.

Now our question: what do you call a marketing strategy that conceptually envisages products becoming obsolete or even giving up the ghost within a certain period of time?
