🇬🇧 Of course, the motors in the hub of #WinD

🇬🇧 Of course, the motors in the hub of #WinDIY_2 must be supplied with energy and data. However, the hub with the motors on it is rotatably mounted and therefore cannot simply be supplied via normal wires. A known solution to this problem is a slip ring that can transmit energy and data to a rotating axis via sliding contacts. The last time I integrated a bought slip ring into the design of #WinDIY. This time I wanted to build the slip ring myself as well. For this I want to cut 9mm wide rings from a 22mm copper pipe and screw them onto a shaft using 3D printed adapters. The electrical connections to the hub are then lead through this shaft. You can see the first attempts and a view of the #CAD model in the pictures. 🙂

You can find more information and detailed instructions for my projects on NerDIY.de 🤓

🇩🇪 Natürlich müssen die Motoren in der Nabe von #WinDIY_2 mit Energie und Daten versorgt werden. Allerdings ist die Nabe mit den darauf befindlichen Motoren drehbar gelagert und kann deshalb nicht einfach über normale Leitungen vesorgt werden. Eine bekannte Lösung dieses Problems ist ein Schleifring der über Schleifkontakte Energie und Daten an eine drehbare Achse übertragen kann. Das letzte mal habe ich dazu einen fertigen Schleifring in das Design von #WinDIY integriert. Dieses mal wollte ich aber auch den Schleifring selber bauen. Dazu will ich aus einem 22mm Kupferrohr 9mm breite Ringe schneiden und über 3D gedruckte Adapter auf eine Welle aufschrauben. In dieser Welle werden dann die elektrischen Verbindungen zur Nabe hergestellt. Die ersten Versuche und eine Ansicht des #CAD Modells seht ihr auf den Bildern. 🙂

🇬🇧 On the two-layer board for the #pxlDigit_24 I tried to accommodate the same hardware as for the #pxlBlck_multiPCB. Because of the "only" two-lqyer PCB, this was not that easy. In addition to the ESP32, a BME280 climate sensor, an RTC, a micro SD card slot and an I2S DAC are installed on it. A TSL2591 is also installed on the front. I installed this in the segment that, statistically speaking, lights up the least often. So you can measure the ambient brightness on the front of the display. You just have to be careful not to do this when the LED in the relevant segment is currently lit. 😬⁣
The PCB was made by the guys of @pcbway. 😍

🇩🇪 Auf der zweiseitigen Platine für das #pxlDigit_24 habe ich versucht die gleiche Hardware wie für das #pxlBlck_multiPCB unterzubringen.⁣
Aufgrund der "nur" zweiseitigen Platine war das gar nicht so leicht. Neben dem ESP32 sind darauf ein BME280 Klimasensor, eine RTC, ein micro SD Kartenslot und ein I2S DAC verbaut. Auf der Vorderseite ist zusätzlich ein TSL2591 verbaut. Diesen habe ich in dem Segment verbaut, dass statistisch gesehen am wenigsten oft leuchtet. So kann man also die Umgebungshelligkeit auf der Frontseite des Displays messen. Man muss nur darauf achten, dass man dies nicht tut, wenn die LED in dem betreffenden Segment gerade leuchtet. 😬⁣

🇬🇧 In the meantime I also continued to work on the #Anemometer for #WinDIY_2. The @elegoo Mars 2Pro was really a game changer in that regard. Because with it you can now print very fine and at the same time overhanging structures. The air blades shown have, for example, a wall thickness of 0.5mm and are accordingly light. At the same time, the hardened resin is very stable and flexible. I am curious how it will behave under UV and weather influences. 🙂 The wind direction sensor will later be installed above the air blades. More information will follow soon. 🙂⁣

🇩🇪 In der Zwischenzeit habe ich auch an dem #Anemometer für #WinDIY_2 weiter gearbeitet. Der @elegoo Mars 2Pro war in der Hinsicht wirklich ein Gamechanger. Denn damit kann man nun auch sehr feine und gleichzeitig überhängende Strukturen drucken. Die gezeigten Luftschaufeln haben zum Beispiel eine Wandstärke von 0.5mm und sind dementsprechend leicht. Gleichzeitig ist das ausgehärtete Resin aber sehr stabil und flexibel. Ich bin gespannt wie es sich unter UV und Wettereinfluss verhält. 🙂 Oberhalb von den Luftschaufeln wird später noch der Windrichtungssensor montiert. Weitere Infos dazu folgen bald. 🙂⁣

🇬🇧 I think it's time to lift the curtain on my previously secret project. 🙂 In the last few weeks I have been working on my #pxlDigit_24. This is a modular 24-segment display with which not only numbers but also letters can be displayed in a rather retro style. For this I designed a PCB on which an ESP32 and 24 WS2812 LEDs can be installed. Several of these PCBs can then be assembled into a display. The arrangement does not matter. You can arrange them next to each other or on top of each other. To make the whole thing a little easier, I created different base holders in which the individual digits can be inserted. You can see a first example in the picture. At this point, many thanks again to the guys of @pcbway who supported me in this project not only with their PCB but also with their rapid prototyping service. The 276mm wide housing shown was manufactured from aluminum using the #SLM 3D printing process. 🙂⁣

🇬🇧 After I solved my winding problem yesterday I could now also deal with the rotor for # WinDIY_2. To do this, I inserted the 40x10x10mm magnets from @supermagnetecom into the holder integrated in the rotor. To make the alignment a bit easier, I marked the poles of the magnets beforehand. Then the individual magnets were inserted into the rotor at the same distance and fixed with a 3D printed bracket. Sometimes it was really not easy to insert the very powerful magnets without pulling the already inserted magnets out of the holder. 😬😂 At this point, many thanks again to the people from @Supermagnetecom who support me at the development with their products. 🙂⁣

🇩🇪 Nachdem ich mein Wicklungsproblem gestern gelöst habe konnte ich mich nun auch mit dem Rotor für #WinDIY_2 beschäftigen. Dazu habe ich die 40x10x10mm großen Magnete von @Supermagnetecom in die im Rotor integrierte Halterung eingesetzt. Um das Ausrichten etwas zu erleichtern, habe ich zuvor die Pole der Magnete markiert. Danach wurden die einzelnen Magnete im gleichen Abstand in den Rotor eingesetzt und mit einer 3D gedruckten Halterung fixiert. Teilweise war es wirklich nicht leicht die sehr kraftvollen Magnete einzulegen, ohne dass die bereits eingelegten Magnete wieder aus der Halterung gezogen wurden. 😬😂 An dieser Stelle nochmal vielen Dank an die Leute von @Supermagnetecom welche mir die Magnete für die Entwicklung zur Verfügung gestellt haben. 🙂⁣

🇬🇧 After a short fight with a very unruly coil equipped with 500m of copper wire, my cordless screwdriver and I would like to solemnly announce that the first coil for the stator of the generator from #WinDIY_2 has been wound. 😍 Why did it take so long? At first I had planned to use my winding machine #WinDIYngThing for this task. But first I had to fix a bug in the firmware. After I was done with it I noticed that the NEMA17 stepper motors used are much too weak to wind up the 1mm copper wire properly. So in the end I hacked my cordless drill to use it as a winding machine. 😎 You can see the first result in the pictures. 😌

🇩🇪 Nach einem kurzen Kampf mit einer sehr widerspenstigen Spule bestückt mit 500m Kupferdraht möchten mein Akkuschrauber und ich feierlich verkünden, dass die erste Spule für den Stator des Generators von #WinDIY_2 gewickelt ist. 😍 Warum das so lange gedauert hat? Zuerst hatte ich geplant meine für #WinDIY gebaute Wickelmaschine #WinDIYngThing für diese Aufgabe zu nutzen. Dazu musste ich aber erst einen Bug in der Firmware beheben. Nachdem ich damit fertig war fiel mir aber auf, dass die verwendeten NEMA17 Schrittmotoren eh viel zu schwach sind um den 1mm Kupferdraht ordentlich aufzuwickeln. Letztendlich habe ich also meinen Akkubohrer gehackt und zur Wickelmaschine ungebaut. 😎 Das erste Resultat seht Ihr auf den Bildern. 😌

🇬🇧 After a few anxious minutes in which I thought my T-962 had grilled all 100 WS2812 3535 LEDs on the pxlBlck_multiPCB, a stone fell from my heart: All components on the second revision work properly. 😎 Animations, icons, scrolling texts and other notifications can now be displayed on the front. The built-in sensors can be used to read air humidity, temperature, air pressure, brightness, UV index, 12 touch electrodes and acceleration values/orientation. In addition, additional sensors can be connected via the #qwiic connection from @sparkfun. The 3W I2S DAC also works. MP3 files can be played from the built-in uSD card slot or as audio stream via WiFi. For example, another neopixel LED strip can be connected via the #Stemma 3pin connector from @adafruit. This way, you could set up a kind of "Ambilight". Did I forget something that should be included in the next revision? 😌⁣

🇬🇧 The gondula of #WinDIY_2 will be aligned

🇬🇧 The gondula of #WinDIY_2 will be aligned in the azimuth axis with the help of a geared motor. This saves the normally used wind vane. The "disadvantage": Another sensor is required to measure the wind direction and ideally also the wind strength. I've finished a first draft. Unfortunately, I think the sensor is still a bit too big. The housing has a diameter of 40mm and is therefore significantly thicker than the "fin" at the end of the gondula of WinDIY_2 on which I would like to install the sensor. Let's see if I can get the whole thing a little smaller. 🙂

🇩🇪 #WinDIY_2 soll in der Azimutachse von einem weiteren Getriebemotor ausgerichtet werden. So spart man sich den Aufbau einer Windfahne. Der "Nachteil": Es wird ein weiterer Sensor benötigt um die Windrichtung und am besten auch Windstärke messen zu können. Einen ersten Entwurf habe ich fertig. Leider finde ich den Sensor noch etwas zu groß. Das Gehäuse hat einen Durchmesser von 40mm und ist damit deutlich dicker als die "Finne" am Ende der Gondel auf der ich den Sensor gerne verbauen möchte. Mal gucken ob ich das ganze noch etwas kleiner bekomme. 🙂

🇬🇧 New PCB post from @PCBway. 😍 I've tried two new things. The first is a PCB that is made of aluminum instead of FR4 material. This board is part of my up-down-light that I briefly introduced a few months ago. There is space for 15 WS2812 LEDs and one 3W LED on the circuit board. The advantage of the ALU PCB is that the large surface of the board can better transport and dissipate the heat loss from the LED. Depending on the LED power, no or just a small heat sink is necessary. 🙂 ⁣
The other PCB is for an AS5048 rotation angle sensor. With three of these sensors I want to read out the current pitch angle of the blades from #WinDIY_2. This means that the angle of attack can be read out with an accuracy of 0.0219 °. I'm not sure if the resolution is necessary, but as always: better to have than to need. 😎⁣

🇬🇧 A few unimportant details are still missing, such as the hub cover, but the basic structure of #WinDIY_2 is ready. 😎 On the rendered pictures you can see the mounted gondola on a 70mm standpipe. The blades are not finished yet, but you can see the actuators, offset by 120°, for setting the angle of attack in the hub. In the picture with the hidden rotor, the magnets (red/silver for north/south pole) are visible in Halbach configuration. You can also see the blue stator which I already printed as you can see in my last posts. 🙂 The bracket for the electronics and a few other little things are still missing. I am still a little unsure how I will get all the electronic components waterproofed. 😬⁣ Any ideas? 🙂

🇬🇧 In case someone should have wondered what the "multi" in pxlBlck_multiPCB stands for: It is because LED matrices of different sizes can be operated with this PCB. Either you solder 100 WS2812 3535 LEDs directly on the back to form a 10x10 matrix or you simply connect an external 16x16 or 8x32 LED matrix to the connection pads. There are three connection pads for GND and 5V on the PCB. In this way, all connection lines of the external LED matrix can be connected and the energy can be evenly distributed. Thanks to USB-C, the matrix can then draw up to 15W. 🙂 The four layer PCB is made by @pcbway

🇩🇪 Falls sich jemand gefragt haben sollte wofür das "multi" in pxlBlck_multiPCB steht: Es kommt daher, dass LED Matrizen verschiedener Größen mit diesem PCB betrieben werden können. Entweder man verlötet 100 WS2812 3535 LEDs direkt auf der Rückseite zu einer 10x10 Matrix oder man schließt einfach eine externe 16x16 oder 8x32 LED Matrix an die vorgefertigten Anschlusspads an. Dazu gibt es auf dem PCB jeweils drei Anschlusspads für GND und 5V. So können alle Anschlussleitungen der externen LED Matrix angeschlossen und die Energie so auch gleichmäßig verteilt werden. Dank USB-C kann die Matrix dann bis zu 15W beziehen. 🙂

🇬🇧 I finally found the bug! Now the pxlBlck plug-in for ESPEasy also runs reliably on the ESP32. I also updated the "RandomPixel" screen saver. The colors are now selected based on the HSV color space and are therefore a little more varied overall. This screen saver slowly fills the entire LED matrix with random colors.⁣
BTW: This is the prototype of the #pxlBlck_16x16 in which the #pxlBlck_multiPCB is used for the first time. More information will be available soon. 😎⁣

Der Bildschirmschoner füllt die gesamte LED Matrix dabei langsam zufällig mit zufallsfarben.⁣

🇬🇧 In the picture you can see the first (top) and second version (bottom) of the stator and the rotor (white) for #windiy_2. I had planned the first version of the stator in such a way that the prepared windings could be pushed into the corresponding shafts. However, this way they could not be attached properly. In addition, the air gap between the magnet and the coil was unnecessarily enlarged. The new stator is constructed in such a way that the windings are screwed on from the outside diameter. This reduces the air gap by about two millimeters to 6mm. The gap between rotor and sator is 2mm. I am looking forward to the first tests. But now it's time to start winding the coils again. 🙂

🇩🇪 Auf dem Bild sind die erste (oben) und zweite Version (unten) des Stators und der Rotor (weiß) zu sehen. Die erste Version des Stators hatte ich erst so geplant, dass die vorbereiteten Wicklungen in die entsprechenden Schächte eingeschoben werden können. Allerdings ließen sie sich so nicht richtig befestigen. Außerdem wurde dadurch der Luftspalt zwischen Magnet und Spule unnötig vergrößert. Der neue Stator ist so aufgebaut, dass die Wicklungen von außen aufgeschraubt werden. Dadurch verringert sich der Luftspalt um gut zwei Millimeter auf 6mm. Der Spalt zwischen Rotor und Sator beträgt dabei 2mm. Ich bin gespannt auf die ersten Tests. Nun steht aber erst mal wieder das Wicklung wickeln an. 🙂

🇬🇧 Last night I printed the coil inserts for the generator from #WinDIY_2. The wire of the windings is wound onto this. Then they are inserted into the "pockets" in the outer radius of the stator and screwed to it. To do this, I changed the design of the stator a bit. (More on this later) In this way, the prepared coil inserts can be screwed to the stator relatively easily and the very tight tolerances can also be adhered to. 🙂⁣

Danach werden sie in die "Taschen" in dem Außenradius des Stators eingesetzt und mit diesem verschraubt. Dazu habe ich das Design des Stators nochmal etwas verändert. (Später mehr dazu) ⁣
So lassen sich die vorbereiteten Windungseinsätze relativ leicht mit dem Stator verschrauben und auch die recht knappen Toleranzen einhalten. 🙂⁣

🇬🇧 For the #Nerdiskerator (the disk generator of the first version of #WinDIY) I had built a provisional generator test stand. This was precisely tailored to the dimensions of this generator. So unfortunately it did not fit the new generator for #WinDIY_2. So the last days I built a new generator test stand from 2020 aluminum profiles and 3D printed components made of Tough PLA from @3d_prima. It's not quite finished yet, but I think you can already see how its made. This time the structure is also designed that way that generators of various dimensions can be tested. Both the generator bracket and the bracket of the 250W DC motor can be adjusted in height and in the axial direction. This way future generator models should also be easy to test without having to make major changes to the test stand. 😎 A 24V 400W power supply is installed in the lower area of the test stand. The speed of the DC motor can be adjusted using the PWM controller. 🙂⁣

🇬🇧 Possibly you remember the last construction of the pitch actuator for the first version of #WinDIY. At that time I built four versions because after each version I thought that I had now found the perfect design (which of course I didn't have). That's why I want to test the new design more this time before using it in the final design. For this purpose I built a small test setup with which I can test the torque of the pitch actuator. I printed a wheel with a radius of 10cm and attached a rope to it. In order to determine the maximum torque I have attached various weights and determined at which weight the gearbox is blocked. The torque can then be calculated using the weight force of the attached weight. Result: The pitch actuator is strong enough for my application. 😎 But of course every gear also has a final boss. 😌⁣

🇬🇧 The last time I printed parts with my #Elegoo Mars 2 Pro, I simply put the component in the sun to cure it completely. Since the sun doesn't always shine so strong, I built a small UV curing chamber. To do this, I lined an old Tupperware box with some aluminum foil and then glued a UV LED strip with the appropriate wavelength into it. So I can cure the components even on days that are not so sunny. 🙂⁣

🇩🇪 Das letzte mal als ich mit meinem Elegoo Mars 2 Pro Teile gedruckt habe, habe ich das Bauteil danach einfach in die Sonne gelegt um es komplett auszuhärten. Da die Sonne aber nicht immer so schön scheint habe ich mir eine kleine UV Härtungskammer gebaut. Dazu habe ich eine alte Tupperdose mit etwas Alufolie ausgekleidet und dann einen UV LED Streifen mit der passenden Wellenlänge hineingeklebt. So kann ich auch an den nicht so Sonnenreichen Tagen die Bauteile aushärten. 🙂⁣

🇬🇧 The last days my 3D printer is running 24/7. 😎 So I was finally able to test the first parts for the stator for the generator of #WinDIY_2. This time I use a bell-like construction for the generator, which is also known from brushless motors. The stator can be equipped with 12 coils, which are pushed in from behind. At the same time, the axis for the rotor is also integrated in the housing of the stator. The large red ring (in which the ball bearing sits) is already part of the rotor and is ultimately screwed to its housing. Later 10, 20 or, if desired, even 40 magnets (then in Halbach configuration) can be accommodated in the rotor housing. Let's see if it works. 🙂 ⁣
At this point I would also like to thank the people from @3d_prima and @supermagnetecom , who support me at the development and construction with material. 🙂⁣

🇬🇧 After experimenting a bit with the different material combinations, it turns out that the combination of FDM printed worm wheel and SLA printed worm works best for the worm gear. The very smooth surfaces of the two SLA printed wheels also work, but the frictional resistance seems to be higher. At least in this case the no-load current of the motor is significantly higher (approx. 180mA) than with the FDM / SLA configuration (approx. 100mA).
The worm gear reduces its number of revolutions in a ratio of 40: 1. The torque increases accordingly, which should be sufficient for my purpose. I will of course do some more testing here. 😎 At this point, many thanks again to the people from @Elegoo without their Mars 2Pro SLA printer, this construction would not have been possible. 🙂

🇬🇧 Have you ever used the JTAG interface to debug your Arduino project? So far I've always relied on the good old Arduino-style debugging method: with the help of numerous Serial.print("I'm here"), ... Serial.print("I'm here2") ... you always got to the problem at some point. But now I'm stuck. As firmware for the pxlBlck_multiPCB (which will be the heart of my future pxlBlck projects) I use the ESPEasy Framework including #pxlBlck plugin. Long story short: The plug-in works perfectly on the ESP8266 but unfortunately not on the ESP32 which I installed on the PCB. However, it is practical that, unlike its little brother, the ESP32 also has a JTAG interface. With a suitable JTAG debugger, you can examine the running software live during runtime. For example, variable values can be read out or changed during operation or the program can be executed step by step. @Espressif (the manufacturer of the ESP32) has developed a small debugger that can be used to program and debug the ESP32 via its JTAG interface. Unfortunately I didn't plan a JTAG connector in the PCB layout. But with the help of a couple of Dupont cables, I quickly "retrofitted" them. Let's see if I can find the problem now. 😎

🇬🇧 Thanks to the support of @elegoo I can now also produce SLA printed components for #WinDIY. A really cool thing about that: thanks to the higher print resolution with the SLA printing process, you can now also print functional threads. In the video you can see the worm wheel for the pitch actuator. I plan to use an M10 screw as the axis. To do this, the screw is first screwed into the worm wheel. The whole gear was printed including the thread. The first threads fit without any further preparation. For the better fit, I only had to cut once through the thread with a thread cutter. A great relief because this way the thread is straight in the component and can no longer cut missaligned. 🙂

🇩🇪 Dank der Unterstützung von @elegoo kann ich nun auch SLA gedruckte Bauteile für #WinDIY anfertigen. Eine echt coole Sache ist, dass man dank der höheren Druckauflösung beim SLA Druckverfahren nun auch funktionale Gewinde direkt mitdrucken kann. In dem Video seht Ihr das Schneckenrad für den Pitch-Aktor. Als Achse plane ich eine M10 Schraube zu verwenden. Dazu wird die Schraube zunächst in das Schneckenrad eingeschraubt. Das Gewinde im Schneckenrad ist dabei beim Druckvorgang mitgedruckt worden. Die ersten Gewindegänge passen ohne weitere Vorbereitung. Für die bessere Passung musste ich nur noch einmal mit dem Gewindeschneider durch das im Prinzip fertige gewinde schneiden. Eine super Erleichterung, weil das Gewinde so auch gerade im Bauteil ist und nicht mehr schief geschnitten werden kann. 🙂

In the meantime I also continued to work on the #Anemometer for #WinDIY_2. The @elegoo Mars 2Pro was really a game changer in that regard. Because with it you can now print very fine and at the same time overhanging structures. The air blades shown have, for example, a wall thickness of 0.5mm and are accordingly light. At the same time, the hardened resin is very stable and flexible. I am curious how it will behave under UV and weather influences. 🙂 The wind direction sensor will later be installed above the air blades. More information will follow soon. 🙂⁣

I finally found the bug! Now the pxlBlck plug-in for ESPEasy also runs reliably on the ESP32. I also updated the "RandomPixel" screen saver. The colors are now selected based on the HSV color space and are therefore a little more varied overall. This screen saver slowly fills the entire LED matrix with random colors.⁣
BTW: This is the prototype of the #pxlBlck_16x16 in which the #pxlBlck_multiPCB is used for the first time. More information will be available soon. 😎⁣

Last night I printed the coil inserts for the generator from #WinDIY_2. The wire of the windings is wound onto this. Then they are inserted into the "pockets" in the outer radius of the stator and screwed to it. To do this, I changed the design of the stator a bit. (More on this later) In this way, the prepared coil inserts can be screwed to the stator relatively easily and the very tight tolerances can also be adhered to. 🙂⁣

After I was able to fix a small error in the programming circuit, the test of the LED matrix was still pending. For this I soldered the LED matrix of 100 SK6812 3535 LEDs on another board and then connected it to the board on which the ESP32 Wrover is soldered via a connector. Later everything will be installed on one circuit board. 🙃 I have already tested the remaining components on a separate PCB. With the next iteration, the pxlBlck_multiPCB should (hopefully) be error-free. 🙂⁣

I wasn't in the mood the last days to work on the #pcknplc machine but decided to work on the automatic tip changing today. These can be changed by defining four positions. As soon as a change is necessary, these are approached one after the other and the this way the desired tip is mounted on the pick head. 🙃 This way, the machine can change the appropriate tip depending on the component size and then pick up the component it should place on thr PCB. 😎⁣

(... Continuation of my previous post) So the stepper motor still didn't have enough torque. No problem, I thought, a little more motor current should fix this. So I turned the potentiometer for setting the motor current on the A4988 stepper motor driver to the maximum position. The reference voltage "Vref" is set with this potentiometer. In combination with the resistor "Rs" built into the stepper motor driver (and the now set reference voltage Vref = 0.8V), the following motor current results according to the data sheet of the driver: Imtr = Vref / (8 * Rs) At this point I also noticed that the value 0.1Ohm was installed on the stepper motor for the "Rs" resistor. Sufficient for most stepper motors. Unfortunately I wanted to run my newly installed stepper motor with its maximum current of 1.7A. With this "Rs" value, however, a maximum of only 1A can be set. In order to extend the setting range for the motor current up to 2A, for example, the value for Rs must decrease to 0.05Ohm. Usually not a problem. Unfortunately I didn't have the 0402 SMD resistor there. But: I had an old defective motor driver with the same values. So if I were to unsolder the Rs from the defective motor driver and solder it in parallel to the Rs in the intact motor driver, the total resistance of the two Rs connected in parallel would have to reduce to 0.05Ohm. That's the plan. You can see the conversion in the video. And why that should still not lead me to my goal, you will see in the next post. 🙂 ⁣

This section of the pxlBlck_multiPCB is literally self-explaining. 😂 A large part of the new functionality is now running. I was very curious about the MAX98357 I2S Class D amplifier. This is connected to the ESP32 via I2S. MP3s can be played from the inserted micro SD card, web radio can be streamed or text can be read aloud. The goal is that the pxlBlcks will soon also be able to play audio data. For example, you could be informed acoustically about events in the SmartHome. Alternatively, you could also play a web radio stream in this way. 🙃⁣ The PCB is made by @pcbway. 😍

Complete build guide available here: https://nerdiy.de/en/howto-pxlblck-pxlblck_cassettelamp-aufbauen/

In the last few days I have finished the article for the pxlBlck_CassetteLamp. This lamp is a little homage to the time when music was not on a 512GB micro SD card but in the form of audio cassettes. I thought it was a shame to let the cassettes gather dust in a box in the basement and made a small decorative lamp out of them. With the help of a few # WS2812 LEDs, an ESP8266 and an old USB power supply unit, the pxlBlck_CassetteLamp can be built. With the help of the #pxlBlck plug-in, the lamp also gets a few SmartHome functions and can thus also inform about events in your SmartHome. In addition to the setting options via WiFi, the lamp can also be adjusted with the help of a pen - just as the cassette tape salad used to be wound up. You can find the build instructions including a list of needed materials and detailed pictures on my blog at Nerdiy.de. 🙃

In the meantime I have finished the holder for the tips of the #pcknplc machine. There is space for up to eight tips. Each individual tip is pulled into the correct end position by a small magnet. I've tried different versions and especially experimented with the distance between the magnets and the tips. There should be enough force on the tips to pull them into the correct position. At the same time, they should not be magnetized too much. In this way, I want to avoid that the potentially magnetized tips will attract components when they are not supposed to. 🙃 The holder is required later - depending on the component size - to automatically attach the correct tip to the pick head. 🙃⁣

It doesn't look like much, but it was quite a bit of work. 😂 The controller boards I have used so far are all based on the Marlin firmware.
