Temporary Delay in the Delivery of Unitree Robots Like many other suppliers, we are currently experiencing delays in the delivery of Unitree robots. A shipment from our supplier is currently held in customs, which has unfortunately led to later-than-planned deliveries for previously placed orders. We are actively working with our supplier to resolve this issue and expect more clarity soon, but at this time, we cannot provide any guarantees. Additionally, a new shipment is already on its way, though it will take some time to arrive. Since other suppliers are facing similar challenges, switching to a different provider is unlikely to result in a faster solution. Our top priority remains fulfilling existing orders. If you have any questions or would like to update your order, please do not hesitate to contact our customer service team. We will keep you informed of any further developments.

Examples covered in full detail include a simple LED to a multi-megabyte SD card running the FAT file system. Features of this book Build prototype circuits on breadboard or Veroboard and interface to ARM microcontrollers. A 32-bit ARM7 microcontroller is used in interfacing and software examples. Interfacing principles apply to other ARM microcontrollers and other non-ARM microcontrollers as well. Example programs are written in the C programming language. Use only free or open source software. Download and install all programming tools from the Internet. Template project files are provided for easy project creation. Hardware Interface to LEDs, transistors, optocouplers, relays, solenoids, switches, keypads, LCD displays, seven segment displays, DC motors, stepper motors, external analogue signals using the ADC, RS232, RS-485, TWI, USB, SPI and SD memory cards. Software Once hardware has been interfaced to a microcontroller, software must be written to control the hardware. You will learn how to write programs to operate externally interfaced hardware devices, use timers and interrupts. Also learn how to port FAT file system code for use with an SD memory card, program the PWM to produce an audio sine wave, program the PWM to speed control a DC motor and more. A chapter on more advanced ARM microcontrollers is included with an overview of some of the newest ARM microcontrollers and their features.

Resonances From Aether Days A Pictorial and Technical Analysis from WWII to the Internet Age From the birth of radio to the late 1980s, much of real life unfolded through shortwave communication. World War II demonstrated—beyond a shadow of a doubt—that effective communications equipment was a vital prerequisite for military success. In the postwar years, shortwave became the backbone on which many of the world's most critical services depended every day. All the radio equipment—through whose cathodes, grids, plates, and transistors so much of human history has flowed—is an exceptional subject of study and enjoyment for those of us who are passionate about vintage electronics. In this book, which begins in the aftermath of World War II, you’ll find a rich collection of information: descriptions, tips, technical notes, photos, and schematics that will be valuable for anyone interested in restoring—or simply learning about—these extraordinary witnesses to one of the most remarkable eras in technological history. My hope is that these pages will help preserve this vast treasure of knowledge, innovation, and history—a heritage that far transcends the purely technical.

Practical Introduction to 3D Modeling from Enclosure to Front Panel Embedding a vintage component, creating a professional looking home for a circuit board, or even designing a complex apparatus complete with a chassis – these and many other challenges turn into a stimulating pleasure with FreeCAD. Once you have internalized the basic processes, there are virtually no limits to your imagination. Starting to use a new software is never straightforward – especially with a tool as versatile as FreeCAD. Manageable, but at the same time easily usable individual components provide the starting point in this book. Putting these components together later results in assemblies. In the FreeCAD universe, a workable trajectory is demonstrated. The described procedure is illustrative so the examples are easily applied to custom tasks. The devices were made by the author and illustrated with photos. Creating a 3D design is requiring some effort but the initial investment pays off soon. Besides the impressive spatial representation of the projects, the extracted drawings yield a solid base for documentation and production. Extended FreeCAD capabilities like the unfolding of sheet metal parts enormously add to efficiency and pushes models forward into practical assembly. Soon you will definitely not want to do without FreeCAD!
