naperlou, I agree. The ability to package a complete system on a chip (SoC) is very impressive. With consumer electronic devices being small in size, microcontroller manufacturers are designing and packaging complete product designs on a piece of silicon. The Silicon Lab's Precision32 MCU is quite impressive because a complete barcode scanner is placed into a small iC package. This article is definitely worth sharing with my ITT Tech Students. Great article Parker!

I am impressed too - especially by the thorough but easy to understand technical explanations provided to explain barcode scanner technology. Thanks for a very interesting article that just added to my understanding of this extremely utilized technology that is often taken for granted as well as the possibilities, something that I had not given much thought to before your very well-written article.

Parker, I am very impressed by your ability to implement this unit with a single MCU.  This is becoming the trend.  MCUs with 32-bit processors and lots of supporting functionality (e.g., ADCs) on chip are making it much easier to implement designs quickly and more reliably.  I wonder how much of this implementation is in the software as oppossed to discrete logic as in the past.

Practically all electronic devices today contain metals that may be coming from conflict-ravaged African countries. And political pressures will increasingly influence how these minerals are sourced and used in products.
Conformal coatings present themselves as space-saving alternatives to enclosures for protecting the circuit boards of automotive electronics. They can also provide electrical insulation.
Design for manufacturing (DFM) in mold production means that mold designers evaluate the manufacturability of their molds in the early stage of mold development by collecting all relevant information and applying it to their designs. They also have to consider many other factors, including flow balance, structural stress, and assembly tolerance, in order to ensure successful molding production.
Some adhesives provide strong structural bonds but take hours to fixture and attain handling strength. The technologies that offer the fastest cure do not bear loads or withstand stresses. A new class of adhesives aims to make both stick.
The continued growth of wireless health is a near-certainty. And engineers will be the key to developing and advancing technology solutions.
