Sponsorship Disclosure


I’m in a lucky position that this blog ranks very well on search engines for hot search queries, especially related to the Arduino ecosystem. As a result, this blog has huge number of daily visitors. Moreover, companies get also attracted and so I get regularly free vouchers offered, payment offers for placing SEO links or web shop links, requests for sponsored partnerships etc. And yes, some offers are very attractive – also financial-wise. I receive also some offers due to social other activities, e.g. my tutorial videos on Youtube. Since I put this activities more or less in second place, I do not have the same audience outreach there as this blog has. But still, some offers coming from there are also attractive.

For me, this blog is just a spare time activity. Moreover, I’m happy with my financial situation. Therefore, I typically decline such requests. Nevertheless, sometimes I get requests from companies whose products I have used before, and sometimes even for many years. If I had very positive experiences with their products, I usually think about building up a partnership. In general, I’m not interested in financial benefit but I enjoy the exchange on the newest trends and upcoming products.

Long story short, on this page, I want to set a good example and disclose my partners which have been sponsored me before.

My definition/demands for a sponsored partnership:

  • I have made good experiences with the company and can honestly recommend them
  • The conditions of the partnerships do not correspond to product placement (according to German Law)
    • No money has been transferred
    • Sponsored product value is less than 1000€
    • No (editorial) influence of content
  • The sponsored partnership does not interfere with other agreements, including employment contracts, e.g. the sponsor is not a competitor of my current employer (even though this is my private blog)

Normally, I get vouchers to buy products. The sponsored products may appear in my blog articles, social media image, and videos.
