Mark 3 is good enough.. Now I get to stop procrastinating on the geometry node graph that will place the LEDs precisely in the crystal growth structure. #3dPrinting #Blender #Art #led
Slow and steady wins the race.
Mark 2 in hand, mark 3 in the slicer preview. #3dprinting #blender #led #orcaslicer #art
How am I JUST NOW learning about these LED light bulbs that charge while they're on, and can be used to provide light during blackouts??!!?!?
Continued thread
After years - I still messed this thing up..... At least one of the panels is upside down, which makes it hard(er) to plan out some of the cool designs "normal" #LED #Cubes can do....
But now that I know the issue, and have two larger half cubes - I'll just have to buy the right size panels and try again.
For years I've wanted to make an #LED #Cube - I even bought led matrix boards years ago, they been sitting in a box, just waiting. A couple of days ago I found a simple 5x5 (half cube) to print. So I printed it, finding my matrix boards, I thought, wow this thing printed too big, but it says 5x5 -- Hmmmm, so dummy me printed a 2nd, with the same results. I decided to scale it down 25% - and that worked.... Can you see the problem that took me a day to see?
“Using photometric and spectroscopic sensors, we observed up to 50% night sky darkening during Earth Hour from 2011 to 2024 in Hong Kong, primarily as a result of a small but critical number of lights-out instances in central business districts, as evidenced by crowd-sourced photography records. The emission reductions mostly occurred in the 445–500, 500–540, and 615–650 nm spectral ranges---corresponding to peak emissions from LED billboard screens--- and in the 585–595 nm range, associated with metal halide floodlights used for facades and billboards. Our study identifies these sources as major contributors to urban light pollution.”

Contemporary shower fixtures are only one of the items that rankle the president. He has frequently denounced toilets that he claims require flushing “ten or 15 times” and LED lightbulbs, which he faults for making him look orange.

dank neuer Beleuchhtungstechniken hält unsere Umwelt auch neue Vergnügen bereit - heute: LED-Beleuchtung beim Sterben zusehen.
Nach ein paar Jahren trennt sich hier die Spreu vom Weizen - bei manchen meiner LED-Lampen schon nach eiben hlben Jahr. LED enthalten oft immer noch seltene Erden - das Recycling von LED ist zur Zeit noch nicht etabliert.

#BigDipper must be the most famous #constellation 
️ I chose to represent it entirely. It's made of #LedLights, a secondhand wooden #frame and pressed elder flowers and solanum

Do #led #flashlights lose their overall brightness over time? I’m sort of concerned too about using any “turbo” setting that drives the LED as hard as I can.
Hi there !

Immer mehr #Gärten sind nachts hell erleuchtet – doch das schadet Mensch und Tier. Denn der natürliche Hell-Dunkel-Rhythmus steuert lebenswichtige Prozesse wie #Zellregeneration und #Schlaf.
Die Initiative Paten der Nacht macht auf die Folgen von #Lichtverschmutzung aufmerksam und ruft dazu auf, #Gärten nachts dunkel zu lassen – für gesunde #Lebensräume und mehr #Artenvielfalt.

Display-Technik: OLEDs für alle oder doch besser LEDs?
Nachdem sich OLEDs im Smartphone etabliert haben, starten sie jetzt auch in Notebooks durch. Bei TVs und Monitoren gewinnen andere Techniken gerade Land.
