I am not sure why, but when recording my latest video I had an unusually large number of bloopers, fails and questionable decisions.
Could be because it was a new subject for me, a stressful June month with a lot of tight deadlines at my day job and a major sewer project on the street I liv...

Time for a new subject after making videos for over a decade. Well, not really new, since I will test a magnet. Not a permanent magnet, but an electromagnet!
I have bought my first commercial electromagnet and will do some initial tests with it in this video. Including comparing it to a sim...

Time for part 3 of my series on bad colors. After not having the wanted success with the filters for my fluorescent studio lights, I unbox and test some new LED studio lights of much higher quality in this video. Are they better?

As you know from the unboxing video here on Patreon, I have bought a professional beam dump. I finally found time to properly test it against my homebuilt beam dump.
Will my DIY model fail in the comparison when tested with three of my strongest lasers?
To improve on the homebuilt model,...

Time for part 2 of my series on bad colors. I let you know what the difference is between the two color profiles used in part 1.
I then explore and try to fix the underlying issue with the colors in a cheap way. Will it work?
The last two years' pandemic has caused a flood of UVC germicidal lamps. Even a renaissance for an odd light bulb, GTL3, I haven't heard about before and apparently was considered obsolete by the industry.
In this video, I take a closer look at the science behind this hybrid of an incandesc...

Time for a little series here on Patreon on the 'color profile' of my videos. This will likely be at least a three part series.

Phew. This may be my shortest video in 2022 so far, but it took more time and effort to make than usual. I am neither a graphics designer nor an animator but needed a lot of graphics in this video. While the animations may look simple, they were a challenge to pull off for an amateur like me. Hop...

My upcoming video will be on laser focus. It may seem trivial, but it matters in ways people may not be aware of. Like the effects of choosing different laser colors and focal length.

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...

Time to find out if the unbranded, cheap laser power meter is any good. At $79 including shipping, my expectations were set low. However, if it is better than not having a laser power meter at all, the price is attractive.
In the video, I compare it to the Sanwu Tracer 20W I have used for y...

I am often asked if there is a cheap laser power meter I can recommend. I have not had a good answer so far.
But through the help from one of my Turkish viewers, I may have found one. I bought it for $79 including shipping. That's dirt cheap for an LPM!
In this video, I unbox and demo th...
Final video of the year. As mentioned in my previous Patreon video, I learned a lot from making videos in 2021. This final video is no exception.

All right. It is time to take a closer look at the laser engraver I unboxed in the last video here on Patreon.
But with a twist: I will compare its laser to an LED lamp. Both are based on blue light diodes and advertised as being around 5 watts.
Sounds similar, right? Let's take a clo...

When tested on my laser power meter - calibrated to 450 nm - how high will it read?

After a rather boring 2020, I am upgrading heavily on my creative tools in 2021. First a 3D resin printer and now it is time for a laser engraver.

I honestly did not know how the magnetizer/demagnetizer tool worked before starting on this video. The online answers I could find were vague (or just wrong) in explaining how it works.

Using an ND8 filter on different lasers in the divergence video, I felt like it really didn't lower the power 8 times as specified. To my eyes, the spots looked too bright.
