You can support Hardware Insights! Power supply testing requires not only lots of knowledge, but also a lot of sophisticated equipment. There is always something new to measure or do it better and more precisely! And the better the equipment, the higher the purchase cost. Below is a couple of things I would like to get, you can of course donate for anything you like or to no particular goal as running the site also has its costs (hosting, domain etc.). If you have suggestions feel free to let me know.
For those who would like direct bank account transfer within Europe, see my Czech website for transparent bank account.
Power analyzer Prova PF9811 to precisely measure not only input AC power but also power factor and do basic harmonic distortion analysis. Ordinary wall wattmeter can be easily fooled by not-present/working PFC.
Differential probe for oscilloscope to accuratelly measure ripple 100% in accordance with Intel ATX specifications.
Gutless wonder for review
We haven’t got any gutless wonder for a long time! Nobody is willing to send samples of such things, donate so I can buy some.
High-precision digital multimeter, for example UNI-T UT805A.
My Panasonic Lumix DMC-FZ4 is obsolete by todays standards, so I am thinking about upgrade for a long time. Maybe FZ50?
