The idea of offering the gerbers allows low-level supporters to give something and get something that doesnt cost you anything. Just a thought. Might give you more dollars than asking for donations that more than cover the cost of the board and parts and shipping.
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.
