Testing eBay infrared filter and homebuilt laser

Added 2020-07-10 15:25:18 +0000 UTC

In this Patreon exclusive for patrons I will test some laser related items donated by... patrons.

Thanks to Piter Soft for sending a home-built laser based on a laser diode from a DVD burner. I will test the power and wavelength of it.

Thanks to zedd for sending an inexpensive infrared filter from eBay and the "filter" that was replaced in his high-powered green laser pointer. I will test how well they filter infrared. I am bit surprised by the result...

At the end there is also a teaser for my next public video. Planned for release on Friday, July 31st.

Good Summer to all fellow Northern Hemispherers! And good luck with the winter for the rest of you. The weather in Denmark is like autumn at the moment...
