Donate to this blog

(Update: April 16, 2024)

  • Are you reading the articles on this blog with great interest?
  • Do you regularly come back looking for new articles?
  • Is this blog a valuable addition to your electronics hobby?
  • Do you appreciate that this blog is not full of Google ads?
Show your appreciation for the many hours of work spent on this blog and donate a small amount once or regularly.

What do I do with your donations?

I'll fulfill two of my wishes:
  1. Buy better measuring equipment for the tests on this blog
    To better perform the popular tests of affordable (measuring) equipment and kits, I want to invest in better and additional measuring equipment. On the wish list:
    - AC mV meter.
    - Audio generator with very low distortion.
    - Harmonic distortion meter.
    - Variac.
    - A 199999 meter as a reference for my multimeter tests.
  2. More budget for the purchase of products to be tested
    I buy most of the tested products myself because I don't want to build up a dependent relationship with suppliers and manufacturers. That is why fairly cheap products are tested. With your donations I also get the opportunity to buy some more expensive products for the tests.

How can you donate via PayPal?
