The Scots Guide to Electronics

This course is designed to help you learn about components, circuits, and the use of electronics. You can explore the contents in whatever order you wish.The emphasis is on providing information starting at the 'absolute beginners' level, but we hope eventually to provide material of use to anyone interested in electronics and its applications ...

The Scots Guide to Electronics

This section of the Scots Guide deals with Analogue Electronics with a special emphasis on Audio-related topics. There are also some specialist pages on the properties of cables as these relate to audio.

The Scots Guide to Electronics

The First Eleven - Basic electronics courses sometimes make it appear as if electronic engineers have an obsession with voltmeters, batteries, and oscilloscopes. That's because it's often convenient to talk about these when presenting a course at a university, college, or wherever. In reality, the physics and electronics of practical systems like Hi-Fi's, TV's, computers, etc, are much more interesting.

The main components used in electronics are of two general types: passive (e.g. resistors and capacitors) and active (e.g. transistors and integrated circuits). The main difference between active and passive components is that active ones require to be powered in some way to make them work. Active components can also be used to amplify signals.

Digital-to-analog converter

A DAC converts an abstract finite-precision number (usually a fixed-point binary number) into a physical quantity (e.g., a voltage or a pressure). In particular, DACs are often used to convert finite-precision time series data to a continually varying physical signal.

Electronic Shift Monitor

The Security Guard duty monitor below, shown in eight circuits at Digital Circuits - 1 are examples of logic circuits, i have converted them from the DOS Orcad to Orcad 9 and corrected some errors a few years back.

Electronic Shift Monitor - delabs

These circuits can be used for looking at the logic blocks or to learn. This product was built and sold to some firms many years back. Now these designs are best done with a PIC or Atmel chip. Here is the user manual

This circuit was done with CMOS CD40xx type of ICs. A RAM was used to store the Day/Time LED Status.

It was to monitor the Alertness of the Security Guard. Periodically the Unit will Buzz and Flash and the Security Guard has to press a Big Button to indicate he is awake, alert, agile and around the Unit.

All Green means fine, few Red LEDs means the Guard was sleeping or gone away from some times. All Red means Security Guard is missing. :-)

Analog Mux for Data Acquisition Systems

Here is a 4-20 mA In/Out Analog Mux with Cascade option. This is a simple circuit i designed to make a Automation System within a budget.

Analog Mux using 4051

This takes 4-20mA from many Transmitters and gives out just one 4-20 mA output. The Mux is done with a digital byte or word.

 Industrial Process Control Circuits

This is a slow scanner as process is slow, that way many analog inputs can be multiplexed and sent into one analog input of a D/A. In near real time systems a faster mux could be used or mux totally avoided. This was made in some numbers, so the pcb is better than others.

Online Electrical and Electronics Books

Some books that will help you learn electronics and are free too. Youngsters have a great wealth to find in the libraries. The Present day has made more information available online, it supplements the library resource.

What can never be found in libraries are found on the net and can be searched too. Here every individual shares his projects, ideas and designs and is not edited or moderated by any publisher or media.

Navy Electricity and Electronics Training Series (NEETS)

These are nice Mini Reference Books that can build the Learning of EE students. Some interesting booklets - Circuit Protection, Control, and Measurement; Intro. to Wave-Generation and Wave-Shaping; Microelectronics and Test Equipment..

Navy Electricity and Electronics Training Series

Some of the Books on Embedded Systems and Communications are quite good and even the sample chapters will bring an appetite to study the subject and buy the Book.

United States Navy Electricity & Electronics Training Series - NEETS

The Navy Electricity and Electronics Training Series (NEETS) was developed for use by personnel in many electrical and electronic related Navy ratings. Written by, and with the advice of, senior technicians in these ratings, this series provides beginners with fundamental electrical and electronic concepts through self-study. The presentation of this series is not oriented to any specific rating structure, but is divided into modules containing related information organized into traditional paths of instruction.

Multi Zone Temperature Controller System

This is a Multi Zone Temperature Control panel used in Plastic Extrusion Moulding. Building such panels helps us learn cable management techniques.

Multi Zone Temperature Controller

The panel is a standard way it was built and some of the merits were the selection of panel components and wiring expertise.

Electrical Control Panel Wiring

Just like rackmounts hold big instruments or computers, control panels small or big have to hold DIN Instruments, switches and annunciators to make it easy for the operator. The maintenance work also is simple from the backside. It can be kept near the machinery which it controls.

RF circuit design - theory and applications

The objective of this textbook is to develop the RF circuit design aspects in such a way that the need of transmission line principles is made clear without adopting an electromagnetic field approach.

RF circuit design - Theory and Applications

Therefore, no EM background is necessary beyond a first year undergraduate physics course in fields and waves as provided by most colleges and universities. Students equipped with the knowledge of basic circuit theory and/or an exposure to microelectronics can use this book and cover the entire spectrum from the basic principles of transmission and microstrip lines to the various high-frequency circuit design procedures.

RF Circuit Design - Theory and Applications by R.Ludwig and P.Bretchko

For the advanced students the entry into this field is often pursued through an electromagnetic field approach, while for the technologists the basic circuit aspect embedded in Kirchhoff's laws is the preferred treatment.

Op amps for everyone – Ron Mancini

The operational amplifier ("op amp") is the most versatile and widely used type of analog IC, used in audio and voltage amplifiers, signal conditioners, signal converters, oscillators, and analog computing systems. Almost every electronic device uses at least one op amp.

Op amps for everyone: design reference By Ron Mancini

"The op amp is treated as a completed component in this book.The op amp will continue to be a vital component of analog design because it is such a fundamental component. Each generation of electronics equipment integrates more functions on silicon and takes more of the analog circuitry inside the IC.

Op amps for everyone – Ron Mancini

Op amps for everyone

Don’t fear, as digital applications increase, analog applications also increase because the predominant supply of data and interface applications are in the real world, and the real world is an analog world. Thus, each new generation of electronics equipment creates requirements for new analog circuits; hence, new generations of op amps are required to fulfill these requirements. Analog design, and op amp design, is a fundamental skill that will be required far into the future."
