This is a practical project course where you will learn the entire PCB design process by designing your own STM32 development board. Many people can perform embedded programming using STM32, but they often struggle to design their own development boards. Even if they have learned how to use EasyEDA, they frequently fail to apply it to real projects and get stuck at the level of simply copying schematics available on the internet. Furthermore, many feel overwhelmed when looking at an STM32 datasheet, unsure of which pins to connect, how to connect the Crystal, why BOOT and Reset circuits are necessary, or how to design the USB circuit. This course was created to solve these exact problems. Rather than just explaining the menus in EasyEDA, we will go through the entire process of designing an actual STM32 development board from start to finish. Students will gain experience in the actual product design process by drafting schematics and performing PCB artwork while designing their own STM32F103C8T6 (Blue Pill) and STM32F407VET development boards.

🛠️ [Course Introduction] "Real" HVAC Scheduling from an 18-Year Veteran Do you know what task takes up the most time and causes the most stress when working at a construction site? It is **'schedule revision.'** In the past, I also spent countless nights drafting HVAC construction and commissioning schedules. Construction sites are prone to delays due to unexpected variables, so wrestling with schedules every month—or even every week—was my daily routine. Looking back, the real reason I struggled so much was that **'no one ever properly taught me.'** There was no basic training on how HVAC relates to other trades or how to actually calculate the time required for construction or commissioning. Consequently, the schedules I spent so much time creating often lacked the accuracy needed to be useful on-site. Then, I had a great opportunity to receive intensive training on scheduling. Once I understood the principles, I honestly felt a bit frustrated. I realized that it’s quite simple once you know the core concepts, and I had wasted so much time during projects simply because I didn't know the method. Ultimately, a construction project is a battle of 'resource management.' The three most important resources to manage on-site are materials, manpower, and equipment. Schedules are created to manage these resources efficiently and are immediately revised when changes occur to prevent delays in the overall construction period. In other words, the schedule is a critical document that serves as the standard for overall project management. While large construction companies may have dedicated scheduling teams, practitioners in each trade must fundamentally be able to draft their own schedules. This is because the schedules of each part come together to form the massive framework of the entire project schedule. That is why I have prepared this course, packed with the practical insights I've gained from 18 years in the field. • Scheduling Basics: What types of schedules exist on-site, and what/how a practitioner should draft them. • HVAC-Specific Practice: Scheduling examples and exercises tailored to actual HVAC work, from representative duct installation to commissioning. • Know-how to Avoid Trial and Error: Tips to stop wasting precious time on meaningless schedule revisions like I did. If my explanation is insufficient or if you get stuck while studying, please do not hesitate to ask questions at any time. Just like an HVAC system that must run 24/7, I will be standing by to provide reliable answers to your questions!

"Have you ever seen months of overtime vanish with a single piece of paper?" Do you know what I felt most poignantly while managing five overseas EPC projects? It is the **'terror of understanding procedures.'** The interesting thing about the EPC world is that while every site is different, they are strangely similar, like a parallel theory. If you slip up in this game of procedural wits, you’re in big trouble. It is the fate of EPC that even a single task requires breaking through countless approval lines and gateways; if you fail to grasp this, the results of months of pouring your soul into your work can go down the drain overnight. 💡 'Real' experience built while being hammered by the Middle East's Big Three Fortunately, whether it was luck or grit, I managed to save and successfully complete every major overseas project I was assigned. Thanks to that, I am confident I can tell more vivid stories than anyone else on 'how to run an overseas EPC project well without failing.' In particular, you can't ignore the 18 years of experience I gained while being pushed to my limits by the three most notoriously difficult Middle Eastern clients (KOC, ADNOC, ARAMCO). I will extract and share only the most essential, life-saving insights on how these demanding clients pressure procedures and operate their systems. 🚀 For your 'life with evenings' To be honest, I created this lecture because I felt so bitter about the glorious 'trial and error' of my younger days. I truly hope my colleagues and junior engineers never have to experience the terrible mistakes I made—hitting rock bottom on-site day and night, falling into a mental breakdown because I knew nothing. I sincerely hope this survival guide becomes a cheat code that moves your clock-out time forward by even just one hour and reduces unfair overtime. 🛠️ 5-minute standby Q&A support If you find yourself thinking, "What on earth does this mean?" or if there is anything you don't understand while taking the course, please do not hesitate to reach out via the bulletin board or email. Like a strict safety manager who sticks to the site and never leaves, I am standing by, ready to give you clear answers to your questions! Let's find the strength, fighting!

Having spent 10 years as an HVAC engineer at overseas EPC sites, there is one truth I have realized most poignantly: "All hardships culminate in commissioning." In the case of HVAC, the construction team often handles everything up to commissioning, so everything from writing the procedures to the moment the valves are opened and the equipment is started was entirely my responsibility. As I wove together everything from massive equipment, ducts, and piping to precise automatic control cables and instruments, I often found myself confused as to whether I was an engineer or a maestro conducting a grand masterpiece of performance art. Furthermore, once you step into this rugged world of commissioning, even the reliable Quality team suddenly exits backstage. The pressure of having to shoulder everything from preparation to final inspection solely as the construction team... Thanks to that, I had to spend countless nights working overtime under the starlit skies of the Middle East. Whenever I stayed up all night amidst the hot desert winds, I thought desperately: "If someone had just spoon-fed me the big picture and the fine details of commissioning, wouldn't my clock-out time have been moved up just a little bit?" This lecture was born out of those numerous nights of overtime. It is my hope that the know-how I have accumulated through 14 years at construction sites and 3 years at data centers will be used to shorten the workdays of juniors and fellow engineers who are struggling in the field at this very moment. In this lecture, we will dissect the major equipment that serves as the heart of the plant HVAC system, the instruments that act like a fine neural network, and the mechanisms of automatic operation. I have also meticulously organized the objectives and essential equipment for each stage of commissioning, from Pre-commissioning to the Performance Test. Rather than a simple recitation of theory, I will vividly convey precautions that must never be missed on-site through real-life cases soaked in my blood, sweat, and tears. If there is anything in the explanation that feels slightly lacking or if you are confused about on-site application while listening to the lecture, please do not hesitate to ask questions. Like an emergency generator that reliably protects a site during a blackout, I am standing by, ready to run at full capacity to answer your questions at any time!

Welcome to the "dungeon" known as the data center. I remember my first day reporting to the data center operations team three years ago. Even though I was a 10-year veteran of construction and commissioning who had seen it all, I have to confess... I was intimidated. (Laughs) "Is this the same HVAC I used to know?" "If I make a mistake here, will it make the national news?" That feeling of your heart racing with half-excitement and half-anxiety—you’re probably feeling it right now, aren't you? Once I actually got into it, I realized the skills I learned while breathing in dust at plant sites didn't just disappear. However, this thing called a "data center" definitely has a different personality than a typical building; it is much more prickly and sensitive. Working as a Lead Engineer, whenever I saw juniors falling into a state of "mental breakdown" with the exact same expression I once had, I would see my own reflection from three years ago. "Man, I had to learn the hard way by banging my head against the wall, but I want to teach these guys so it hurts a little less for them." This lecture was created with that single thought in mind. I’ve already gone ahead, experienced the trial and error you'll face, and even put together a complete "incorrect answer note" for you. I have packed in all the know-how from my 17-year engineering career—mixed with my blood, sweat, and refrigerant. So, please feel free to dig in, tear it apart, and savor every bit of it. If you ever think, "What on earth does this mean?" while studying, don't hesitate to ask on the bulletin board or via email. I will come to answer you faster than a UPS (Uninterruptible Power Supply) and with more energy than an emergency generator. Now, shall we get started?

--- Learning a technology means reclaiming the choices in your own life --- You may have connected an ESP32 development board and sensors before, but the process of developing a jumper-wire experiment into a complete device can feel daunting. There is a great deal of information online about circuit design, PCB fabrication, sensor control, and BLE and Wi-Fi communication. However, connecting this scattered information and completing a board that actually works requires a great deal of trial and error. In this course, you will design and build an ESP32-based sensor board yourself. You will configure the power and firmware download circuits, connect temperature and humidity and light sensors, design a PCB with KiCad, and order it for fabrication. Once the board is complete, you will upload firmware to it and transmit sensor data externally via BLE and Wi-Fi. By the end of the course, you will be able to go beyond simply assembling development boards and sensor modules: you will understand and be able to modify circuits and PCBs to suit your own purposes. The project completed in the course can be reused as a starting point for new projects such as environmental monitoring devices, smart home devices, educational kits, and IoT prototypes. Even in an era when generative AI can rapidly create digital content, physical information such as temperature, humidity, light, and movement in the real world can only be obtained through sensors and hardware. The ability to collect data with a device you built yourself and connect it to a network gives you the power to turn ideas into real-world systems. This course will be helpful for: * Those who have used Arduino or ESP32 development boards but are new to PCB design * Those who want to turn a sensor project made with jumper wires into a single complete board * Those who want to learn KiCad by following an actual ESP32 project * Those who want to build a device that collects sensor data and transmits it via BLE and Wi-Fi * Makers and educators developing environmental monitoring, smart home, or educational hardware * Aspiring entrepreneurs preparing their own IoT products or prototypes * Developers and content creators who want to analyze or process data collected from the real world or use it with AI models Move from being someone who uses development boards to someone who designs their own boards. This course does not merely teach you how to use sensors. It is a course where you experience the entire process of turning an idea into a circuit, turning the circuit into a PCB, and connecting the completed hardware to a network.
