A Fast-Lane Ride From Concept to Project The core of the book explains the use of the Raspberry Pi Zero 2 W running the Python programming language, always in simple terms and backed by many tested and working example projects. On part of the reader, familiarity with the Python programming language and some experience with one of the Raspberry Pi computers will prove helpful. Although previous electronics experience is not required, some knowledge of basic electronics is beneficial, especially when venturing out to modify the projects for your own applications. Over 30 tested and working hardware-based projects are given in the book, covering the use of Wi-Fi, communication with smartphones and with a Raspberry Pi Pico W computer. Additionally, there are Bluetooth projects including elementary communication with smartphones and with the popular Arduino Uno. Both Wi-Fi and Bluetooth are key features of the Raspberry Pi Zero 2 W. Some of the topics covered in the book are: Raspberry Pi OS installation on an SD card Python program creation and execution on the Raspberry Pi Zero 2 W Software-only examples of Python running on the Raspberry Pi Zero 2 W Hardware-based projects including LCD and Sense HAT interfacing UDP and TCP Wi-Fi based projects for smartphone communication UDP-based project for Raspberry Pi Pico W communication Flask-based webserver project Cloud storage of captured temperature, humidity, and pressure data TFT projects Node-RED projects Interfacing to Alexa MQTT projects Bluetooth-based projects for smartphone and Arduino Uno communications

The State of Hollow State Audio in the Second Decade of the 21st Century Vacuum-tube (or valve, depending upon which side of the pond you live on) technology spawned the Age of Electronics early in the 20th Century. Until the advent of solid-state electronics near mid-century, hollow-state devices were the only choice. But following the invention of the transistor (after their process fell to reasonable levels), within a couple of decades, the death of vacuum tubes was widely heralded. Yet here we are some five decades later, and hollow-state equipment is enjoying something of a comeback, especially in the music and high-end audio industries. Many issues surround hollow-state audio: Does it produce—as some claim—better sound? If so, is there science to back up these claims? How do hollow-state circuits work? How do you design hollow-state audio circuits? If hollow-state equipment fails, how do you go about troubleshooting and repairing it? Can we recreate some of the classic hollow-state audio devices for modern listening rooms and recording studios? How can we intelligently modify hollow-state amplifiers to our taste? These and other topics are covered in The State of Hollow State Audio.

This DIY Color Display Kit is a fun and educational project for makers of all ages. It is a great way to learn about electronics, programming, and improve your soldering skills. Microcontroller As this kit ships with the ePulse Feather ESP32 development board, the kit thereby inherits all the great features of said devkit. Display The large 3.5" 320x480 color display also sports a high-precision capacitive touch interface. Contrary to resistive touch interfaces that often work best when using a stylus this auto-calibrated module offers a smartphone-like user experience. Connector PCB The connectors for the display are already pre-assembled on the connector PCB, as those require a more experienced hand at the soldering iron. Hence, for the inexperienced solderer this offers the best of both worlds. Also, you may choose to not add the on-off switch or the Grove connector; both are optional. The connector PCB offers extendability in two ways: the broken out pins of the microcontroller and the connector for the Grove system.

Contents Basic principles A connector is an electromechanical system that provides a separable connection between two subsystems of an electronic device without an unacceptable effect on the performance of the device. It will be shown that there are a lot of complex parameters to handle properly to make this statement true. Design / Selection / Assembly This chapter provides an overview of design and material requirements for contact finishes, contact springs and connector housings as well as the major degradation mechanisms for these connector components. To complete this chapter, material selection criteria for each will also be reviewed. Additionally the Level of Interconnection (LOI) was integrated into this chapter as it addresses, where the connector is used within an electronic system and therefore influences the requirements and durability of the connector depending on its use. Applications This chapter is heading to the practical work and shows how customers use connectors in their applications to offer some possibilities and to ease your daily work. Additionally it contains some special topics like tin-whisker or impedance of ZIF cable to offer you extended background knowledge.

The tripod adapter is custom machined from a solid block of aluminum, and provides two standard tripod mounting points with 3/8-16 and light-duty 1/4-20 thread respectively. This allows you to mount the AxiDraw to a tripod, should you have reason to do so. We would highly recommend using a sturdy tripod with a 3/8-16 connection point and appropriate counterweight (sand bag, lifting weights, etc) to balance the weight of the AxiDraw while in use. Installation is straightforward, and does not require any tools other than those included with AxiDraw: Remove the existing foot pads from the AxiDraw (either standard or outrigger feet, depending on model) and attach this plate to the captured nuts in the bottom surface of the AxiDraw. For AxiDraw SE/A3 (April 2019 and newer), the tripod adapter attaches directly to tapped holes in the base of the machine. This heavy-duty tripod adapter is compatible with AxiDraw V3, AxiDraw V3/A3 and AxiDraw V3 XLX. It is also compatible with AxiDraw SE/A3 manufactured in April 2019 and newer. Specifications Material: Anodized 6061-T6 aluminum Size: 3.90 x 2.36 x 0.35 inches (99.1 x 60 x 8.3 mm) Weight: Approximately 144 g Mounting hardware: included (four M4x10 high-strength steel mounting screws)
