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. Downloads Manual

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.

Learn to 3D Model & 3D Print with Tinkercad With this book and the complementary videos, you’ll be 3D printing in no time at all. This course is meant to have you make casings for electronic components but also goes into optimizing your print technique as well as adding a little flair to your 3D creations. The course is perfect for you if you just bought your (first) 3D printer and want to print your own designs as soon as possible while also being able to get more background information. You’ll get to know the workings of a 3D printer and what software to use to model your object, not forgetting to make it print perfectly. We’ll even use the magic of 3D printing to create things that appear impossible to make (this fast and simple) with any other rapid-prototyping technique. At the end of this course, it’ll be second nature for you to design an object for 3D printing and fine-tune your print-setting to get the perfect print! The book includes the following 7 video tutorials: Introduction Basic 3D modeling for 3D printing Modeling a casing Post-processing Pushing the limits Movable parts Snap fits

This book contains more than 400 simple electronic circuits which are developed and tested in practice by the authors. The technical solutions presented in the book are intended to stimulate the creative imagination of readers and broaden their area of thought. This should allow readers to look beyond the horizons of possibilities and use ordinary electronic items in a new way. This book includes new and original radio electronic multipurpose circuits. The chapters of the book are devoted to power electronics and measuring equipment and contain numerous original circuits of generators, amplifiers, filters, electronic switches based on thyristors and CMOS switch elements. Wired and wireless systems as well as security and safety systems are presented. Due to the high relevance and increased interest of readers in little-known or not readily available information, the different chapters of this book describe the use of electronic devices in industrial electronics and for research, as well as new instruments and equipment for medical use, gas-discharge and Kirlian photography. A number of technical devices presented in this book are related to research of the mysteries of the earth, nature and human beings by using radio electronic devices. This book will be useful for both radio amateurs and professionals.
