Aubrey Kagan

Born and raised in what was then Rhodesia (now Zimbabwe), Aubrey Kagan completed his electrical engineering degree at the Technion, Israel Institute of Technology, and obtained an MBA at the University of the Witwatersrand in South Africa. He immediately started working in electronics and was fortunate enough to be around as microprocessors made their first inroads into industry. He was initially involved with designing controllers for industry and mines, with projects encompassing coffee packaging machines, railroad communication controllers, hydrological data monitors, automatic calorimeters, and diamond sorters. The isolation of South Africa (geographically, economically, and later politically) allowed him to gain a wide range of experiences with many aspects of the industry, including analog and digital circuit design, the use of PCs (including the use of spreadsheets) to gather data, and the early use of CAD. Aubrey now lives in Canada. Here he originally worked on the specifications for the Canadarm 2 (the remote control arm on the International Space Station), but he is now involved with far less grandiose projects. He is Engineering Manager at Emphatec, a Toronto-based design house of industrial control interfaces, signal conditioners, and switch-mode power supplies. Micro experience includes Intel (8048, 8051, 8080, 8085), RCA (1802), Zilog (Z80, Z8), PIC (16Cxxx), Scenix (SX18), TI (TMS7000, MSP430), and Cypress (PSoC1/4/5). His specialty lies in blending the linear with the digital hardware and then processing in software. Aubrey has written several technical articles for Circuit Cellar and has contributed several design ideas to EDN and Electronic Design as well as an application note for Cypress Microsystems. He blogs for embedded.com, Planet Analog and EE Times.He is also the author of "Excel by Example: A Microsoft Excel Cookbook for Electronics Engineers".

Several years ago our own inimitable Max published a blog “Want a Voltera Desktop PCB Printer?” that described a PCB printer that was being developed…

Switch interfaces

Everywhere you look in industrial electronics there are switches and contacts: proximity switches, limit switches, relay contacts, activation switches and sometimes even keyboard switches. At…

Some of you may remember the blog “The app I need” where I discussed the features that I would like in an electronic notebook that…

Flashing LEDs

Almost every micro-based project that I have designed in the past 25 years has had a flashing LED, originally as a “health” indicator, but the…

Monkeys everywhere

I feel a rant coming on! I have just been to visit my mother in South Africa and I found many examples of designer oversight…

Back EMF and snubber

Electrical engineering students are taught about magnetics and that energy is stored in an inductor when it is energized. This can be presented in a…
