In my latest public video I tested two laser power meters with strong lasers from 20 to 1500 mW. But what if I test them with a weak laser pointer well under 5 mW? Not as easy as it sounds, since even the heat from my hands can mess with the results...

At the end of the video, I also have a teaser for the upcoming February video. Perhaps my craziest magnet experiment so far? Scheduled for release Sunday, February 27th.

By the way, today is Valentine's Day. I am not a fan of forced appreciation and apparently the European Space Agency, ESA, sometimes feels the same :o) They send me some funny, free merchandise with Anti-Valentine's Day messages. You can see the full selection and have a smile here: https://www.esaspaceshop.com/ Or just have a Happy Valentine's Day!

The Mini can't display 1 mW?

While testing the "Mini" laser power meter, I noticed it never displayed 1 mW - even when cooling down to 0 mW. In this video I test it with a ~1 mW keychain laser pointer. How will it perform compared to the Sanwu laser power meter?
