Project Developer John Robertson – Project Consultant Al Schwabenbauer – Project Evaluator Tom McGlew – Project Development Manager A presentation of eSyst.org eSyst Project Overview A presentation of eSyst.org So what has changed and what is a System? Then to Now A presentation of eSyst.org Now to the future What has Changed? Today, the greater part of a tech’s work now deals at a higher level. Specifically, he or she works more with: • larger PCBs containing many ICs • plug-in modules and subassemblies • complete pieces of equipment • entire systems as well as their power and cabling The focus is on signal flow through the system and testing the system to see that it meets specific standards. Rarely does the tech replace individual components such as transistors, diodes… A presentation of eSyst.org Impact to AAS Degree Programs in Electronics Technology • Most AAS programs were initiated in 70s & 80s or earlier. • Massive changes in technology. – Integrated circuits, higher density SoC. – Higher frequencies and digital speeds. • Massive changes in the way products are designed, manufactured and serviced. • Students leaving programs early. • Students not even considering electronic careers. A presentation of eSyst.org Impact to Graduate Technicians • Major implications for technicians. – Few if any engineering technician jobs. – Less troubleshooting to the component level. – More system troubleshooting, measurement and test. Results in: • Legacy programs being out of touch with reality. A presentation of eSyst.org The Legacy Bottom Up Approach A presentation of eSyst.org The Top-Down Approach A presentation of eSyst.org A Solution: eSyst • eSyst project conceived to address the systems view of electronics and industry's current needs. • Develop new curricula and courses to address previously mentioned problems. • Encourage colleges to update programs. A presentation of eSyst.org Course Resources Developed by eSyst Project Team – – – – – – DC and AC Circuits Analysis Solid State Devices and Circuits Digital Logic and Circuits Microprocessor Applications inc. microcontrollers Data Acquisition and Measurement Communications A presentation of eSyst.org Project Status • Project has resources for the following on eSyst.org: • DC/AC • Solid State Fundamentals • Digital Logic • iLabs Application Phase One available online – Phase Two is under testing • Microprocessor Applications • Data Acquisition – underdevelopment • Communications - underdevelopment A presentation of eSyst.org New Courses Extend Systems Concept The Textbook Problem Solution A presentation of eSyst.org Two Courses Most AAS Programs Do Not Have But Should • • • • Instrumentation/Data Acquisition Communications Both topics should be core courses. Both topics are inherent in all tech jobs today. • It is almost criminal not to teach these subjects leaving grads unprepared for realworld work. A presentation of eSyst.org Instrumentation • What technicians do most: Test & measure (T&M). • Exotic test equipment more common as companies test more complex products to standards. • Some T&M taught within existing courses. • More exposure needed to advanced test equipment and methods. (e.g. digital scopes) • Virtual instrumentation is now widespread but rarely taught. • Key problem: Lab equipment costs, lack of instructor knowledge. • One solution: Virtual instruments in Multisim & LabVIEW. A presentation of eSyst.org Data Acquisition • Data acquisition (DAQ) a key part of instrumentation. • Very wide spread usage in all industries. • Techs regularly install, set up and operate DAQ systems. • Topics: DAQ concepts, sensors, signal conditioning, sampling/ADC, storage, software) • Easy to teach. Lab costs low. • Include NI LabVIEW. A presentation of eSyst.org Communications • What segments of electronics are NOT affected by communications in some way? • Key elements of communications are: – Wireless – Networking • Huge subject area and very systemsoriented. • One course is not enough but has to be in an AAS program. A summary course. A presentation of eSyst.org What to teach in communications? • • • • • • • • • Spectrum & radio waves, propagation. Digital modulation and multiplex/access. Cell phone technologies. Common short range wireless (Wi-Fi, Bluetooth, ZigBee, ISM, etc.) Antennas and transmission lines. Networking principles. Ethernet Internet, TCP/IP, fiber basics & Sonet/SDH. Basic test instruments (e.g. spectrum analyzers) A presentation of eSyst.org The Textbook Problem • Most texts still somewhat dated. • No texts cover electronics from systems view. • Publishers reluctant to pursue systems approach for fear of dumbing down the books and losing sales. • Publishers slowing revisions due to low sales. • Publishers not publishing new technology books due to small market. A presentation of eSyst.org Potential Solutions • Talk to the publishers. Explain your needs and back it up with adoptions. • Use free books like that available from www.openbookproject.net/electricCircuits • Enhance and/or replace existing books with manufacturer’s literature. • Develop your own materials from Internet resources. • Use modules from MATEC. www.workreadyelectronics.org • Push for e-books and by-chapter sales. A presentation of eSyst.org Web Site Tour • Demonstrate eSyst web site: • Review new courses resources • Review Online Evaluation forms • Systems Lab Activities • Show the Implementation Guide www.esyst.org A presentation of eSyst.org eSyst at Columbus State Community College Keith Sanders Presentation link A presentation of eSyst.org eSyst at Chabot College Wayne Phillips Chabot College ESYS Program A presentation of eSyst.org eSyst Microprocessor Animation Bassam Matar Chandler-Gilbert Community College http://esyst.org/Courses/Microprocessor/animation.html A presentation of eSyst.org eSyst Home Theater Animation Lou Frenzel http://esyst.org/Courses/Home_Theater/animation.html A presentation of eSyst.org Break Return at 3:00 p.m. A presentation of eSyst.org eSyst System Lab Demonstrations A presentation of eSyst.org Wrap-Up Questions and Survey Final Thoughts A presentation of eSyst.org Thank You to everyone for participating in today’s Electronics Systems Technology Project Workshop www.esyst.org A presentation of eSyst.org
