Realize that anything mechanical once one gets to the sub-atomic level is mostly empty space, and the color of an object is the response to light to the object's electromagnetic fields that help old the electrons in place with the nucleus -- it is what in part gives all these different properties like conductivity and dielectric constant and modulus of elastisity, and tensile strength in part to materials
This article totally speaks to me. I seem to manage some level of competence with MCU hardware, software, schematic design and layout. My head does a pretty good job of envisioning what the mechanical components should look like and how they should operate. But, when it comes time to build mechanical things, I tend to struggle. It seems like it shouldn't be that big of a deal, but it is.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
