@ Max. Ref your query on comparing motors. Change to a common system of measurements, I prefer metric in this case and N.m, Using Newtons work of Force= Mass x Acceleration (F=ma) convert 0.78kg to Newtons by muliplying by g (accelation due to gravity 9.81 m/s/s) this gives 7.65N-cm. Then convert cm to m by dividing by 100, 0.0765N-m then multiply by 1000 to get mN, hence 76.5mN-m, so motor 2 is better by 2.5%. I've been racking my brains to remember the formulae to calculate the speed/accelaration to weight section, but it currently escapes me.
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.
