International Engineering Consortium - IEC

IEC manages the 270-university Electrical and Computer Engineering Department Heads Association ECEDHA, dedicated to sharing information and maintaining awareness of industry needs and direction.

International Engineering Consortium - IEC

Today, the IEC maintains its mission as a partnership between academia and industry by providing quality continuing education, research, publications, and service programs for the international information industry.

The IEC became a strong force in the remarkable growth of the electronics industry, keeping many thousands in the industry up to date, adding to its roster of prominent university affiliates and industry sponsors

The Demise or Renaissance of Classic Control

By Tom Lee Ph.D. - Chief Education Officer, Quanser
Adjunct Professor, Systems Design Engineering, University of Waterloo

At the 2014 ECEDHA conference, held in Napa, Quanser conducted a focus group on the future of the conventional control systems lab. Quanser is well known for its motion systems and plants used in a wide range of control teaching and research applications.

System-on-Chip - SoC - IP

When a product has to be made small, the board real estate is limited or it has to be manufactured in large numbers.... SoC is the Answer. A Microprocessor evolved into a Microcontroller by packing many external chips into one chip. Now uC Card along with the other blocks like A-D, Port Drivers, Networking elements, Display Driver and other peripherals can be packed into one chip.
System-on-Chip - SoC - IP

Some Power Supply and RF blocks cannot be easily added inside as they have a silicon processing more specific to their applications. Laser trimmed Instrumentation Op-Amps, high accuracy resistor arrays, high value capacitors, magnetics and supporting chips are placed outside on the PCB.

The SOC can pack Digital Chips, Memory, A/D, D/A converters, uC, RAM and Custom programmable areas. For more specialized communications, analog and power requirements; Special SoC types can tackle RF and Power management within a chip because of proprietary silicon processing expertise.

System on a chip - Wiki

"A system on a chip or system on chip (SoC or SOC) is an integrated circuit (IC) that integrates all components of a computer or other electronic system into a single chip. It may contain digital, analog, mixed-signal, and often radio-frequency functions—all on a single chip substrate. A typical application is in the area of embedded systems."

Programmable SoC offers an alternative to custom ASIC as you can make different products from the same chip, yet make products that are portable and low power. The software, pcb, user interface and support components has to be redesigned for every unique product. Many standard IPs are available for Design and Reuse.

Nuts and Volts DIY Magazine

Online edition of US print magazine Nuts and Volts. Aimed at the electronics hobbyist, with articles covering amateur radio, cellular communications.

Nuts and Volts DIY Magazine
 
Nuts & Volts is written for the hands-on hobbyist, design engineer, technician, and experimenter. The diversity of subjects appeals to all levels of experience and spans such topics as amateur robotics, circuit design, lasers, computer control, home automation, microcontrollers, data acquisition, new technology, DIY projects, electronic theory, and more, not to mention the popular BASIC Stamp.

Adding More Digital I/O to your 16-Bit Experimenter Kit 

16-Bit Experimenter Kit - Nuts and Volts
If you’ve been following the 16-Bit Micro Experimenter series in Nuts & Volts, you are already familiar with its solderless breadboard environment and the fully programmable 10 line I/O expansion bus that comes with the kit. The 10 lines can be assigned to be digital, analog or even connected to any of the PIC24F Microcontroller’s internal extensive peripheral set (i.e. dual UART, five CCP modules, ADC, Real time Clock Calendar, dual SPI, and dual I2C).

The Mini-Bench Supply

A small power supply with +5V, +12V, and -12V outputs is a handy thing to have around when you’re breadboarding circuits with both op-amps and digital ICs. You would want a switching regulator for efficiency, but linear regulators for low noise. Plus, it should be easy to build and relatively inexpensive.
