@Caleb Check out the "Hupfeild Phololist violano" on you tube and other video sites. It dates back to like the 1920s and is a self playing Violin piano machine, entirely pnuematic. There is also the electric Mills Violano Virtuoso. Both play from paper rolls (Which my Gadget can read.)
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.
