While the 2 week turn around issue still stands, prices for low volume manufacturing have dropped through the floor with companies like OSHPark. $5 per sq inch and you get 3 copies of a full spec 2 layer boards shipped to your door. I have also had boards back in as little as 6 business days, though that's not the norm.
I've done self etched boards, as well as have access to a board router, but the hassle of not having plated vias and holes has pushed me well past the pain threshold. There's certainly still a use for home grown boards and this looks like it takes plenty of pain out, but for personal projects I can wait.
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.
