There's hope on the horizon! I have a patent-pending on a 3-conductor, downward-compatible (makes correct connections between conventional unbalanced and new balanced versions) "RCA" connectors. I'm now actively seeking manufacturers interested in licensing (contact me at firstname.lastname@example.org). Balancing an unbalanced output adds only a few pennies to the BOM - balancing an input (properly, that is) adds less than $2. To me, it's an insult to see RCA connectors on "audiophile" gear that costs $2,000+.
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. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
