Here you can see the #neopixel cube in action, glowing with different colors. The animation was written in #micropython, and I'm quite happy with how it turned out :blobcat_nwn:

It’s time for new projects. Like this small version of the Space Clock as an LED matrix.
It opens up even more possibilities.

Today I took a look at how this toaster is built. It even came with some free pieces of bread, which was a nice bonus... although they probably shouldn't have been near the mains connection and the latch mechanism.

Even though I have other plans for […]

Hey everyone, check out my smart NTP time-synchronized LED Advent candles with Wi-Fi!

I know, it’s a bit early, but that gives you more time if you want to build your own. 😉

After receiving the components, it's time to start the TIX Clock project. 🪄

The WS2812B LEDs are controlled via the ESP32-S2 mini using MicroPython. The time is updated over Wi-Fi from an NTP server during boot.

Now that the TIX Clock is running, all […]

A collage showing a setup for testing individually addressable LED pixels. The top image shows three parallel LED pixel strings taped to a table, with some LEDs lit in red, green, and blue. The LEDs are powered via an ESP32-S2 Mini microcontroller, which is connected to a laptop via USB. A laptop power adapter is also visible. The bottom-left image shows a coiled bundle of unused LED pixel strings and a sealed ESP32 S2 mini. The bottom-middle image is a close-up of the ESP32-S2 Mini with labeled pin headers and connected wires. The bottom-right image shows the laptop to program the ESP32.

I built a #neopixel cube. I saw one at #easterhegg, and it's actually quite easy to recreate :blobcatthumbsup:

It only needs six 8x8 NeoPixel matrix boards and the 3D-printed frame. Putting everything together with the tiny M2 screws was a bit fiddly […]

A USB cable enters the cube from the top and connects to an ESP32-C3 SuperMini inside. The USB cable's outer insulation has been stripped back before the connector, allowing power for the NeoPixel PCBs to be tapped directly from the cable. Many thin gray wires are visible inside A nearly finished NeoPixel cube, with only the top panel still unattached. Inside, an ESP32-C3 SuperMini can be seen, along with a resistor connected to one of its GPIO pins. The outlines of tools are visible in the background

The Bambu Lab A1 Mini 3D printer really had to put in some work printing all those light limiters for me.

But things are coming along. I just need to finish the top row and work on completing the frame with the white fabric cover.

Once that’s done […]

The project is finished!

It’s now called Space Clock because it should also be possible to display other variants on it, such as a binary clock, even though the Tix version is definitely the most impressive.

You can now find it at Haxko in […]

Haven't posted about this topic in a while.
Kinda always looks the same anyway. 🫠

An open electrical control cabinet with multiple rows of components. At the top are miniature circuit breakers (MCBs) and residual-current devices (RCDs). Below them are terminal blocks with organized blue and orange control wiring. On the left side is a Siemens SIMATIC S7 PLC with several I/O modules. On the right side are Siemens industrial Ethernet switches. A Siemens Sitop power supply is also installed. Green Ethernet and fieldbus cables are connected to the switches, while various control and power cables exit the cabinet at the bottom through conduits. Several yellow warning labels are attached to indicate electrical hazards.

It's on the roof and connected.

Of course, this won’t just be left like that. It will be properly mounted.

Time to show the progress, since the project has been completed since last Friday.

The 12 spots each have their own small power supply, which I had to fit into the cabinet.

Below them are twelve small white power supplies. The terminal blocks are now wired and organized. On the right side of the enclosure, two blue sockets with protective lids are mounted. A plastic bottom plate with multiple circular cutouts, intended for cable entries, is placed next to the enclosure on the workbench.
