Very nice Max. In Zimbabwe we get power cuts (for load shedding) for 4-5 hours aa day. When we were back there recently we had one for 14 hours. But 10 days is a loooong time.
We don't have piped gas in Zimbabwe so most people have a petrol (gasoline) or diesel generator. Were I to go back there to live I would get a diesel one with electric start. 20 KW is a lot of power though I guess you would need it with air conditioning. Air conditioners are rare (and not often needed) in Zim. and most people have a small gas (propane) type 2-plate cooker and cylinder for cooking when the power is off. So you can get by with 2-5 KW.
I'd also get solar panels and some batteries and an inverter. If you only want some lights and a TV and fridge you could get by with a 1KW inverter, and you wouldn't have the cost of the diesel or the noise (or the fumes, which get a bit oppressive when everyone has their genny running).
Would it be rude of me to ask how much your generator cost?
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.
