He's trying to calculate the ratio of the circumference of a circle to it's diameter in base 8. We're trying to see how many digits he goes before he gives up. The project is called Occupy Octopi with Octal Pi.
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.
