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:

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.

A Handbook on DIY
Nowadays, security problems are rarely properly solved or correctly addressed. Electronic security is only part of the chain in making a system secure. Electronic security is usually addressed as network or software security, neglecting other aspects, but the chain is only as strong as its weakest link.
This book is about electronic hardware security, with an emphasis on problems that you can solve on a shoestring DIY budget. It deals mostly with secure communications, cryptosystems, and espionage. You will quickly appreciate that you can’t simply buy a trustworthy and reliable cryptosystem off the shelf. You will then realise that this applies equally to individuals, corporations, and governments.
If you want to increase your electronic security awareness in a world already overcrowded with networks of microphones and cameras, this is a book for you. Furthermore, if you want to do something DIY by designing and expanding upon simple electronic systems, please continue reading. Some of the devices described are already published as projects in the Elektor magazine. Some are still ideas yet to be worked out.
Complexity is the main enemy of security, so we'll try to keep to simple systems. Every chapter will analyse real-life espionage events or at least several hypothetical scenarios that will hopefully spark your imagination. The final goal is to build a security-conscious mindset (or “to get into a head of a spy”) which is necessary to recognise possible threats beforehand, to design a truly secure system.
Don’t bother reading if:
you think you and your secrets are 100% safe and secure
you think somebody else can effectively handle your security
you think conspiracy theories only exist in theory – Telefunken’s masterpiece the “FS-5000 Harpoon” was built on one!

Space, the final frontier, will become more and more popular. The space industry is continually growing and new products and services will be required. Innovation is needed for the development of this industry. Today it is no longer possible to follow all the events in field of space. The space market is growing and activities are increasing, especially the market for small-satellites.
This book wants to help close the gap and encourage electronic engineers to enter into the fascinating field of space electronics. One of the main difficulties is finding people with knowledge of space electronics design. Nowadays companies have to invest a lot of time and resources to instruct electronic engineers with no experience of space. Only a brief and basic introduction of this topic is typically achieved at university in space engineering lectures. Professionals with practical experience and the necessary theoretical knowledge are scarce. Companies from the space sector are searching for staff with knowledge of space electronics.
This book will bring space closer aspiring to the space electronic hobbyists.

The Elektor Audio DSP FX Processor combines an ESP32 microcontroller and an ADAU1701 Audio DSP from Analog Devices. Besides a user-programmable DSP core, the ADAU1701 has high-quality analog-to-digital and digital-to-analog converters built-in and features an I²S port. This makes it suitable as a high-quality audio interface for the ESP32.
Programs for the ESP32 can be created with Arduino, Platform IO, CMake or by using the Espressif IDF in another way. Programs for the ADAU7101 audio DSPs are created with the free visual programming tool SigmaStudio by dragging and dropping pre-defined algorithm blocks on a canvas.
