  • Why I like a well-designed bootloader

    Or, also known as: How I pretty much bricked, and then fixed a product I was roadtesting. The following story is something I encountered during my Roadtest of the MKR WAN 1300. (See roadtests.) I've mentioned the programming error I encountered in passing…
  • LoRa Experimental Environmental Sensors (LoRaXes) - Conclusion

    Another Project14 Challenge complete - sort of..... As always, some goals were met and some were not. I thought that I would summarize where I got to. Blog Post Index LoRa Experimental Environmental Sensors (LoRaXes) - Introduction LoRa Experimental Environmental…
  • LoRa Experimental Environmental Sensors (LoRaXes) - Assembly Complete

    I made all the changes needed to the case assembly and I trimmed down the proto PCB and wired the connections to the sensors. Here is a picture of the completed assembly: Not pretty, but looks like a prototype..... At the lower right, next to…
  • LoRa Experimental Environmental Sensors (LoRaXes) - Case Assembly Part 1

    Well, I am running out of time to complete this project. All the usual excuses, out of town guests and other distractions. I am going to do well just to finalize all the construction by next week. I did a test print of the component mounting bracket …
  • LoRa Experimental Environmental Sensors (LoRaXes) - Initial RSSI Tests

    I decided to do some initial RSSI testing at various locations inside my house and outside in the backyard to see how much loss I was getting due to the structure of my house. This is to get a baseline for further outdoor testing. There are two components…
  • LoRa Experimental Environmental Sensors (LoRaXes) - Temperature Sensor Working

    The temperature sensor that I selected is the BME280. It measures humidity and barometric pressure in addition to temperature. The particular version that I'm using interfaces over I2C. There are other versions that will interface with I2C or SPI at the…
  • LoRa Experimental Environmental Sensors (LoRaXes) - Case Layout

    Now that I've gotten some runtime on my new 3D printer and used the new workflow with Cura - I'm ready to start printing the component mounting for the sensor case. Since I've decided to use the larger case, I can mount some of the components vertically…
  • LoRa Experimental Environmental Sensors (LoRaXes) - Introduction

    I recently connected my Things Gateway to the Things Network and this Project14 challenge seemed like a good opportunity to do some experiments with the two MKR WAN 1300 boards that I received with the gateway. I'd like to build a pair of portable…
