Great idea; I wonder though if the brief flight of the arrow can be powered efficiently with energy harvesting techniques. For instance, the company suggests that at 400 ft/sec launch speed the maximum range for the arrow is 95 yards. For more info see this paper: http://www.velocitip.com/Documents/IEEE_Sensors2011.pdf
Sounds to me like it is intended largely for arrow manufacturers where they can use the data to make improvements to their arrows. And since many archers make their own arrows that would apply to them as well where they can now make improvements "on-the-fly".
I wonder what kind of analysis is possible with this system? Is is just the 3 axis measurements and what if any zeroing/recalibration is possible before each flight? It would be nice to add sensors to the ends of the bow to fully monitor the bow/arrow performance - especially if there was some way to synchronize the multiple sensors data logs.
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.
