A strange but cool thing about the lighting at the Stockholm City train station is the thin light strips with RGBW LEDs. The light is not uniform white, but a kind of cold white that almost shimmers in the RGB colors in some weird way that makes it look and feel a lot more like actual daylight than any other LED light I've ever seen. If you don't look directly at them you pretty much think it's a hazy sky.

Does anyone have a source for LED pseudo-lasers that are strong enough to be used for laser light-show style effects, but not a real laser so that if it shines in your eye you aren’t screwed.

Невозможный LED: запитать изолятор
Физика, будучи точной наукой, с огромной неохотой позволяет манипулировать собственными законами. К примеру, изоляторы — это вещества или материалы, которые не проводят (или практически не проводят) электрический ток, что делает их антиподами проводников. Однако данное утверждение не высечено в камне, если подойти к нему креативно. Ученые из Кембриджского университета (Великобритания) создали новый способ питания изоляторов. Что позволило ученым нарушить порядок вещей в физике, какими свойствами обладают новый проводящие изоляторы, и где они могут быть использованы? Ответы на эти вопросы мы найдем в докладе ученых.

[Help] Hissing sound from fanless Raspberry Pi 4
The linked file is a recording of a hissing sound that my Raspberry Pi 4 started to make sometime during the last 24 hours. Another symptom is that the power on and CPU activity LEDs are out. It is not running hot. It doesn’t have an internal fan. It is being cooled by six PC chassis fans. It is running OpenWRT. It has been pumping Linux ISOs in and out non stop for about four months.
I have tried cleaning it by dedusting it. I have also tried rebooting it. While rebooting, it squeals like a mouse, like it was suffering but the LEDs function properly. As soon as it loads user space though and resume routing, they turn off and the hissing sound continues.
Here are some system logs with severities warning and error. As you can see, the logs are from the 15th and I don’t think any of them pertain to the hissing sound and/or the LEDs.
