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.

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.

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.

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

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.

at the top, a red fault indicator light and a green operating light (which is illuminated). Below them, two buttons for exhaust ventilation—one red for "OFF" and one green for "ON." In the middle, there is a large emergency stop button with a red knob and a yellow background. At the bottom, a main switch with a red rotary handle and a yellow safety cover.

The control cabinet is mounted on a wall.The image shows the inside of a wired control cabinet.

On the inner side of the door are the contacts for push buttons and signal lights, neatly wired and secured. Inside the cabinet, terminal blocks, motor protection switches, airflow monitors, zener barriers, and a 24V DC power supply are organized and connected on DIN rails with cleanly routed wiring.A workbench with extraction through the perforated sheet.

#MuesliPLC

The cable tray and DIN rails are riveted in place, and I've started with the wiring 🫠

From this point on, I had to plan and draw the control circuit. Of course, it will be properly done in the end. But for now, the sketch will have to do.

Basically, it's like PLC programming with ladder logic, just with real wiring.

Visible are motor protection circuit breakers with auxiliary contacts, circuit breakers, DC power supply, relays, airflow monitoring modules, Zener barriers, terminal blocks, and wires routed through cable trays.A hand-drawn sketch of the circuit diagram for the control circuit of the fan control.

First preparations for the announced ventilation control.

There isn’t much space on the mounting plate.

#MuesliTech #Automation #Engineering #Industrial #Control

Components temporarily placed on a mounting plate intended for installation in a control cabinet.

First row (top): Starting from the left, there are three motor protection switches, each with auxiliary contacts, followed by a B6 circuit breaker and a power supply unit for 24VDC.

Second row: Three contactors, followed by two airflow monitors, and then four Zener barriers.

Third row: Terminal blocks arranged as 3-pole-terminal and 2-pole-terminal connectors.

The components are neatly organized but not yet secured, resting on the metallic surface of the mounting plate. Surrounding the plate are boxes containing additional parts.

#MuesliPLC

I have a new project. I would classify it under #PLC, even though it is #hardwired.

It's about an exhaust control system for two workbenches in an explosion-protected area.

Basically, it's a series of safety chains to ensure that the machines only run when the exhaust fan is operating. Both workbenches will be monitored by an airflow sensor, which must be routed through a zener barrier.

I will try to show some of this tomorrow.

#MuesliKNX

As previously mentioned, the distribution system was installed today.

In the first picture, you can see how it looked before. Only a few preparations were made, such as removing the side covers and drilling holes for wall mounting.

In the second picture, the distribution cabinet has been installed next to it. I took the photo around midday, and the wiring was essentially completed. The existing wiring was replaced with new wiring leading to the #KNX cabinet.

Since most of the programming was already done, I just had to add the labels during testing.

Tomorrow, the work continues with fine-tuning. I already set the runtime for the awnings today. Tomorrow, I’ll need to reconfigure the dimmers with an adjusted dimming curve for each lamp.

#MuesliTech #SmartHome #Automation #wiring #wires

#MuesliKNX

Alright, time to share something new again. This time, a bistro is getting retrofitted with #KNX. Since the electrical installation is only a year old and all the wiring runs through terminal blocks to the distribution cabinet, it’s quite straightforward to implement. A slim distribution cabinet will be added, containing the actuators, binary inputs, and the visualization server.

I already programmed the system last Thursday and configured the server as much as possible. Installation and switchover will take place on Monday and Tuesday.
