This is a three-part series, that will discuss the engineering process behind the project I wrote about previously. It goes into developing design constraints, component selection, empirical testing, hardware design and assembly, embedded software design, messaging architecture, and cloud data services. Lots of stuff for tasty coffee, but more hardware-focused detail than the previous writeup at wot.io. I hope you enjoy!
Another recent demo I created used the Mediatek LinkIt One, which is an awesome little Arduino-compatible dev board that integrates a ton of useful hardware like GPS, GSM, WiFi, etc. With a tiny bit of code and some cloud data services connected via a flexible message bus, I had a prototype system up and running fast. It’s very simple in the first iteration, parsing NMEA sentences from the GPS unit, extracting data, and sending it off to logic and alerting powered by the data services. I’m still working on refining this, as it’s an itch I want to scratch for my own use.
