Do it yourself: Amiga RGB Video Splitter
With the DIY project linked below, you can output the Amiga's RGB signal to two monitors simultaneously.

I had a lot of "fun" writing the #yaml definition for #esphome . A LOT of "fun". 
Esphome isn't really meant to write complex behaviours like a #child #toy 's program. It's meant for IoT devices: lightbulbs, covers, sensors, devices with very simple behaviors. But it's very convenient as it manages on its own all the wifi stack and libraries stuff, and it provides some functionalities for free (in this case, the possibility to use the whole led strip as a single #RGB #light seamlessly integrated in #homeassistant ).
Is this an #hack ? Sure it is. But does it work? Hell, yeah!

I realized that I'd need a lot of wires, gpio pins and solder joints to control 6 #rgb #leds, so I decided to use #addressable leds, so I bought a #neopixel -compatible #led #strip. I then placed them, two per compartment, and soldered them one piece after another, so they can be all controlled shifting data out of a single GPIO pin.
I also made some holes for the #speaker. Here you can see a test with the #lab bench #powersupply .

To build it, I started with an hexagonal wooden box, already divided in 7 compartments. I needed one compartment for the #esp8266, #speaker, #batteries and #switch, the central one. The external 6 compartment will be illuminated by #rgb leds.

Curious what it takes to write 3D patterns for #Pixelblaze by @wizard?
I've written up a short series of tutorials: https://www.evilgeniuslabs.org/tutorials/pixelblaze3d/part1
Among other examples, I show how to display rainbow-colored 3D Perlin noise on a three dimensional #RGB #LED cube.

Is this mathematical art or what formula is kreatiev? Have fun with it and let's see who is creative and how structured.

Jeroen Boumans And another recent one, my first collab with a collegae astrophotographer.
Captured under Bortle class 3 skies using remote observatory data in collaboration with Joep van der Heiden. This project totals a whopping 25 hours of integration, combining broadband (LRGB) and narrowband (5 nm Hα) to reveal the galaxy’s sweeping spiral arms and faint outer halo.
Previous posts are gone since the Astrodon server closed.
This is the heart of the Heart Nebula: Melotte 15 
. This deep exposure combines narrowband data (SHO) with broadband (RGB) star data. The final integration time adds up to 17h 20m!
The RGB stars were captured separately on the last night to prevent stars from becoming purple in the calibration process.
I've got a question for the #color experts of the fediverse.
I'm trying to figure out what happens to the #RGB values when you move the color picker horizontally in #Krita. I can see that the biggest value remains unchanged, the smallest converges to 0, but what's happening to the third channel? I've experimented a bit by setting things to max/min in the HSL/HSV spaces, but to no avail.
Any ideas or key words I can pass to the duckduck to give me a push in the right directions would be appreciated.
Boosts appreciated.
How it's going.
I also managed to paint two identical colors months apart (see second photo), one in acrylic and the other in oil. This was a total coincidence. Although, many colors are very close to their own complement — because I screw up so much, I nail some right on the head.
The amazing thing about RGB and CMYK is that one just subtracts a numeral from the RGB and CMYK values to find the complement (instead of looking at ancient charts and color wheels). And then you just look at it on the display to reproduce that color, if desired.
I did not learn this in elementary school (in the early 1970s), dammit.
