Trinity Three a light sculpture
only 🔼 🔼 🔼 made.

All the molds for the concrete are hand cut from foam and the lamps are hand sanded which results in minor differences per lamp. The biggest differences are in the cover plate. Therefore you can choose from three variants.

#Skyglow reductions observed during #EarthHour in #HongKong imply that #LED billboards and building façade lighting are "major contributors to urban light pollution."

NatureNatural experiments from Earth Hour reveal urban night sky being drastically lit up by few decorative buildings - Scientific ReportsLight pollution, a typically underrecognized environmental issue, has gained attention in recent years. While controlling light pollution requires sustained efforts, Earth Hour offers a unique natural experimental setting to assess temporary lights-out measures. 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. Weekend lighting pattern in the city during Earth Hour remained unaffected. 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. By combining multimodal observations, we offer a comprehensive assessment of light pollution sources and the potential benefits of sustainable lighting practices in urban environments. This research highlights the importance of targeted light pollution mitigation efforts and provides critical insights for policymakers to enhance urban sustainability and human well-being.

#CircuitPython Sonic Pillars now have a medium tone to match low tone. One more to go. Splotchy animation on right side looks like power prob but should be identical to no prob left. I need to diffuse lights & build some sort of mounting/housing but should be fun. John Park had great advice to add a fade trail to indicate movement direction. #led

Now with eight 32x8 flexible #NeoPixel #LED mateicies & just one signal clearing 330 ohm resistor controlled by one @raspberrypi Pico 2W w/CircuitPytbon, an @adafruit Vl53l1x Time of Flight sensor, & PVM5102 DAC w/speaker out. Will tweak sound & animation & add at least two more pillars w/new tone ranges. Ideas for diffusion? I’ll wait til I get the final fab done but will absolutely post a build tutorial. youtube.com/shorts/iTfHW93_Xi8

Am thinking for starters I’ll just laser cut a wooden circle the circumference of the #LED strip, wrap it around the end, and try some sort of paper cover or other slightly rigid diffuser a bit larger than the circle. This is just under paper at home office with #pixelblaze shuffle. We’re gonna have fun with this! LMK your suggestions for lights to buy and projects to try!

No dia 26 de dezembro de 2012, no Kennedy Center, em Washington, ocorreu a 35ª edição do Kennedy Center Honors. Dentre os homenageados da noite estava a banda britânica, Led Zeppelin, nas figuras de Robert Plant, Jimmy Page e John Paul Jones.

Um tributo memorável.

Impossível não se emocionar.
