Here’s another small KNX project 🫠

This time it’s quite manageable, using a 16-channel switching actuator for lighting, power outlets, and roof window drives in a museum. The new exhibition extension is to be controlled from the reception desk. For this purpose, a KNX touch panel with display is a great fit, as it allows everything to be easily operated by category.

#MuesliTech #KNX

An uncovered sub-distribution panel with various KNX components installed, including a switching actuator, binary input, KNX bus power supply, and a USB interface. A few circuit breakers and an additional power supply are also visible.

At the bottom of the panel is a screwdriver and a temporarily connected KNX touch panel with display, currently showing the category for switchable power outlets.

It's time for the portable Space-Clock in cyber-neon!

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. 😉

Four white LED candles glowing warm white, standing side by side, each connected with two colored wires to an ESP32-C3-SuperMini microcontroller board placed in front of them.
The warm white light softly illuminates a white mug behind them with the inscription 'Merry Christmas'

#MuesliTech

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

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

#MuesliTech #Siemens #Simatic #Industry #PLC #ProgrammableLogicController #SPS

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.

#MuesliTech #haxko

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 Andernach, Germany, during opening hours.

And there’s more to discover

#ESP32 #MicroPython #Neopixel

A light-transmitting canvas stretched over a wooden frame. Colored LEDs glow through the canvas in yellow, green, blue, and red, arranged in clusters that represent the current time in the style of a Tix clock.

#MuesliTech

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, you’ll be able to clearly see the squares when it’s turned on. I already tested it with a frosted plastic panel, and it looked really great. Of course, I didn’t take a photo of it, so it stays a surprise!

The (powered-off) Tix clock is set against a white wooden backdrop, where the Neopixel LEDs and square light limiters are mounted.

Two of the limiters, freshly glued, are each weighed down with a soda bottle and have purple spacers underneath. A long yellow spirit level lies in front, serving as a straightedge.

#MuesliTech

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 that's left is the right case. It's clear that it needs to be a bit larger.

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.

#MuesliKNX

It's on the roof and connected.

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

#MuesliTech #KNX

Electrical control enclosure on a flat roof, with a transparent cover revealing internal components including a 4-channel switch actuator, a 4-channel dimming actuator, 12 small white power supplies, and terminal blocks. The enclosure is connected via several cables entering through cable glands on the bottom side. Two blue sockets with covers are mounted on the right side.

#MuesliKNX

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.

#MuesliTech #KNX

Wired plastic electrical enclosure containing a KNX setup.

At the top, there is a 4-channel switching actuator on the left and a 4-channel dimming actuator on the right, both from Hager. 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.

#MuesliKNX ✨️

A new small KNX project.

Glass canopy above the balcony with an awning, 12 spotlights, and switchable sockets. This box needs to go on the flat roof.

Later, a KNX server will be added to the distribution cabinet in the basement. This time in a proper DIN rail enclosure.

Maybe I need a new category for this

Today, I finally created the circuit diagrams. Until now, there was only my scribbling.

#MuesliTech #CAD #circuits #engineering #industry

Screenshot from the CAD program showing the created main circuit.

Screenshot from the CAD program showing the created control circuit.

Let me give you some context:

I was actually only working on the machine because a pump had stopped running. The error message was already showing on the control screen, but the CNC machine kept running. The worst that could have happened was the coolant collection tank overflowing.

In any case, the transfer pump wasn’t running, and the motor protection switch kept tripping after a few seconds.

I measured the windings on the motor, but everything was fine. Now I’d love to know what the pump was thinking, lol.
Anyway, everything was electrically sound, and the motor protection switch did exactly what it was supposed to do to prevent damage.

After cleaning the collection tank and the pump, everything should be working again.
