The Dragino LDS02 is powered by 2x AAA batteries and targets long-time use, these two batteries can provide about 16,000~70,000 uplink packets. After the batteries run out, the user can easily open the enclosure and replace them with 2 common AAA batteries.
It will send periodically data every day as well as for each door open/close action. It also counts the door open times and calculates the last door open duration. The user can also disable the uplink for each open/close event, instead, the device can count each open event and uplink periodically.
It also has the open alarm feature, the user can set this feature so the device will send an alarm if the door has been open for a certain time. Each LDS02 is pre-load with a set of unique keys for LoRaWAN registration, register these keys to the LoRaWAN server and it will auto-connect after power on.

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:

Whether you are an electronics enthusiast or engineering professional, this book provides the reader with an introduction to the use of the CadSoft’s EAGLE PCB design software package.
EAGLE is a user-friendly, powerful and affordable software package for the efficient design of printed circuit boards. It offers the same power and functionality to all users, at a smaller cost than its competitors. A free version of EAGLE is available to enthusiasts for their own use.
EAGLE can be used on the main computing platforms including: Microsoft Windows (XP, Vista or Windows 7); Linux (based on kernel 2.6 or above) and Apple Mac OS X (Version 10.6 or higher). Any hardware that supports these software platforms will run the EAGLE application.
The book is intended for anyone who wants an introduction to the capabilities of EAGLE. The reader may be a novice at PCB design or a professional wanting to learn about EAGLE, with the intention of migrating from another CAD package.
This book will quickly allow you to:
obtain an overview of the main modules of EAGLE: the schematic editor; layout editor and autorouter in one single interface;
learn to use some of the basic commands in the schematic and layout editor modules of EAGLE;
apply your knowledge of EAGLE commands to a small project;
learn more about some of the advanced concepts of EAGLE and its capabilities;
understand how EAGLE relates to the stages of PCB manufacture;
create a complete project, from design through to PCB fabrication. The project discussed in the book is a popular, proven design from the engineering team at Elektor.
After reading this book while practicing some of the examples, and completing the projects, the reader should feel confident about taking on more challenging endeavors.

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.

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.
