Schematic
The Theremin was the first music synthesizer. The Junior Theremin is our, smaller, version of that classic electronic musical instrument. As you move your hand towards and away from the wire aerial, the Theremin responds by changing the pitch of the note it is playing. It can play individual notes as well as varying the tone of a single note.
How do you use the Theremin?
The wire aerial responds to the movement of your hand towards and away from it and changes the pitch of the note it plays, without actually being touched. Junior Theremin works in two modes – continuous and discrete. When you first connect the battery Junior Theremin is in continuous mode. Pressing both pushbuttons together switches between continuous and discrete modes. Discrete mode, as its name implies, plays individual or discrete notes rather than a continuously variable tone. Eight notes over a single octave are available. In discrete mode the two pushbuttons change the octave of the notes. The left-hand pushbutton (marked -) lowers the octave, and the right-hand pushbutton (marked +) raises the octave. The pushbuttons only change the octave so long as they are pressed. In continuous mode the pushbuttons have no effect.

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.

Learn RC and RL Filters with Hands-On Circuits and Simulation
Introduction to Electronic Filters is your comprehensive guide to understanding, designing, and applying first-order electronic filters using resistors, capacitors, and inductors. Whether you are a student, maker, or educator, this book demystifies the theory behind RC and RL filters and bridges the gap between concepts and real-world applications through simulation and experimentation.
From the basics of frequency response and phase shift to hands-on breadboard builds and Python-based simulations, this book offers a deeply practical learning experience. You will learn to analyse filters using Bode plots and phasors, and explore applications in audio tone shaping, sensor signal conditioning, noise reduction, and power supply filtering.
As you progress, you’ll build, measure, simulate, and tune filters using modern tools like CircuitLab, Python, and the Analog Discovery 3. Each chapter includes thoughtfully crafted activities that reinforce learning by doing – designing filters for specific tasks, simulating dynamic behaviour, and observing how theory translates into performance.
Inside you’ll find:
A clear introduction to the fundamentals of electronic filters
Detailed explanations of RC and RL filters, cutoff frequency, and phase
Guided activities using both simulation and hardware tools
Real-life applications in audio, sensors, power supplies, and more
A beginner-friendly primer on Python and algebra for electronics
Whether you’re working through simulations or experimenting with real components on your workbench, this book will help you develop a solid understanding of electronic filters and their role in practical circuits.
Analogue Electronics and Microcontrollers Projects
Hobbyist electronics can be a fun way to learn new skills that can be helpful to your career. Those who understand the basics of electronics can design their own circuits and projects. However, before you run, you need to learn to walk.
It all starts with analogue electronics. You should be familiar with the simple components and circuits and understand their basic behaviors and the issues you may encounter. The best way to do this is through real experiments. Theory alone is not enough. This book offers a large number of practical entry-level circuits, with which everyone can gain the basic experience.
Through the widespread introduction of microcontrollers, a new chapter in electronics has begun. Microcontrollers are now performing more and more tasks that were originally solved using discrete components and conventional ICs. Starting out has become easier and easier thanks to platforms including Bascom, Arduino, micro:bit. The book introduces numerous manageable microcontroller applications. It’s now a case of less soldering and more programming.
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!
