For Raspberry Pi, ESP32 and nRF52 with Python, Arduino and Zephyr
Bluetooth Low Energy (BLE) radio chips are ubiquitous from Raspberry Pi to light bulbs. BLE is an elaborate technology with a comprehensive specification, but the basics are quite accessible.
A progressive and systematic approach will lead you far in mastering this wireless communication technique, which is essential for working in low power scenarios.
In this book, you’ll learn how to:
Discover BLE devices in the neighborhood by listening to their advertisements.
Create your own BLE devices advertising data.
Connect to BLE devices such as heart rate monitors and proximity reporters.
Create secure connections to BLE devices with encryption and authentication.
Understand BLE service and profile specifications and implement them.
Reverse engineer a BLE device with a proprietary implementation and control it with your own software.
Make your BLE devices use as little power as possible.
This book shows you the ropes of BLE programming with Python and the Bleak library on a Raspberry Pi or PC, with C++ and NimBLE-Arduino on Espressif’s ESP32 development boards, and with C on one of the development boards supported by the Zephyr real-time operating system, such as Nordic Semiconductor's nRF52 boards.
Starting with a very little amount of theory, you’ll develop code right from the beginning. After you’ve completed this book, you’ll know enough to create your own BLE applications.

Unlike other Raspberry Pi boards, the Raspberry Pi Pico does not have a built-in video output. However, thanks to programmable IO (PIO) and this Pico DVI Sock, it is possible to add a DVI video output to the Raspberry Pi Pico!
The Pico DVI Sock was developed by Luke Wren, a Raspberry Pi engineer, in his spare time. He has published the design online under a CC0 license, so everybody can build the hardware from his provided files.
The physical video interface of the Pico DVI Sock is an HDMI connector, but it outputs a DVI signal. Historically, HDMI is a successor to DVI – so DVI signals can be simply transmitted using HDMI. Simple passive adapters allow you to connect HDMI cables to a DVI port.
The DVI Sock can be soldered to one end of the Raspberry Pi Pico. Thanks to the castellated edges of the Pico, soldering is very easy. Let your creativity run wild with an additional digital video output on the Pico.
Here are some suggestions / possible project ideas:

The EggBot is a friendly art robot that can draw on spherical or egg-shaped objects from the size of a ping pong ball to that of a small Grapefruit – roughly 1.25 to 4.25 inches in diameter (3-10 cm).
You can use EggBot on all kinds of spherical objects. Use it to create the most impressive Easter eggs, personalize Christmas ornaments or even golf balls or light bulbs. The EggBot is not just a cool gadget; it’s also a great introduction to CNC (computer numerical control) and do-it-yourself robotics. All of the electronics and software are designed to be hackable and repurposable, so you could easily computer control an Etch-a-Sketch or create something totally new.
The EggBot software allows you to control the ‘bot from within Inkscape – a superb freeware illustration program – on Mac, Windows, or Linux computers. You can draw an image directly, trace a photograph, or import designs from other programs. You can also control the EggBot directly from many other programs that have the ability to send serial commands over a USB port.
Universal power supply included! (with US-EU adapter).
The EiBotBoard ('EBB') is a USB-based dual stepper motor controller board that is useful for many general purpose robotics applications. Originally designed for the EggBot project, it is the 'brain' of all current models of the EggBot, but also of the AxiDraw and WaterColorBot as well. The EBB was designed by Brian Schmalz of Schmalz Haus LLC. It is an open source (in both hardware and software), PIC18F46J50-based motor controller board. Standard features include two Allegro A4983 16X microstepping motor drivers for bipolar steppers. It also has a separate onboard regulator to power up to two hobby servo motors. It is 2.2 x 2.2 inches square (5.6 x 5.6 cm). We are currently shipping version 2.7 of the EBB, which features several improvements for reliability. Version 2.7 uses a standard USB micro connector and has a switch that by default turns off power to the pen-lift servo motor after one minute of inactivity. You can change the timeout duration or disable this feature using the serial command protocol. Specifications Motor driver ICs: Two Allegro A4983 Stepper motor type: Bipolar (2) Step size: Full, 1/2, 1/4, 1/8, 1/16 Motor connectors: Screw terminal USB jack type: Micro-B Power connector: Barrel Jack, 2.1 x 5.5 mm, center positive Voltage input range: 9-25 V DC Output current adjustment: 46 mA to 1.25 A per phase Downloads/Documentation GitHub

Sound Secrets and Technology
What would today’s rock and pop music be without electric lead and bass guitars? These instruments have been setting the tone for more than sixty years. Their underlying sound is determined largely by their electrical components. But, how do they actually work? Almost no one is able to explain this to the true musician with no technical background. This book answers many questions simply, in an easily-understandable manner.
For the interested musician (and others), this book unveils, in a simple and well-grounded way, what have, until now, been regarded as manufacturer secrets. The examination explores deep within the guitar, including pickups and electrical environment, so that guitar electronics are no longer considered highly secret. With a few deft interventions, many instruments can be rendered more versatile and made to sound a lot better – in the most cost-effective manner.
The author is an experienced electronics professional and active musician. He has thoroughly tested everything described here, in practice.
