This week we’re starting to make our Micropython powered Wemos D1 truly useful with a sensor and data collection. We’ll wire up a BME280 sensor which measures temperature, humidity and air pressure. After we know it works, we’ll use Wifi and MQTT to send the data to a website for viewing. (View on youtube)
Last week we covered how to flash Micropython onto an ESP8266 (Wemos D1 Mini) but we had to type our code into the REPL by hand. That’s not terribly useful for a real world project, so this week we learn how to upload code and make it run on boot. We’ll be using a tool called Ampy, by Adafruit, since the Micropython world is a little immature.
Welcome to Episodes #01 of the new Obviate.io video series where we’ll be flashing Micropython 1.9.3 onto a Wemos D1 Mini ( ESP8266 ) development board using Apple macOS.
Just two months ago we bought a Miracle-Gro AeroGarden Bounty Elite as a Black Friday deal. Previously I covered the activity in the first two weeks of growth. At the time I felt it was surprisingly fast and continue to feel that way. In just 6 weeks from planting we’d grown from pods, to sproutlings, to decent sized plants with flowers, to visible tomatoes! So now it’s just a matter...
Recently Kinesis released the Freestyle Edge which is a new mechanical version of their previous “Freestyle2” split keyboard (which was membrane based). While the Freestyle Edge is advertised for gamers, I think any serious user should seriously consider it. It has most of the critically important features you see on all “ergonomic” keyboards today including split angels, tenting and a lot of adjustability.
