I wrote about building a Raspberry Pi-based weather monitoring systems back in July, 2019. The solution utilizes Ruuvitag bluetooth beacons to measure temperatures and other data, and then submits those readings to Azure using Azure IoT Hub and Azure Functions. That setup is still working well today. I also wrote about building a new housing cabinet for my network hardware using an IKEA cabinet. As part of this small hobby project I evolved my previous… Read More »Building a Raspberry Pi-based temperature monitoring solution with Sense HAT LED matrix display and Azure Logic Apps (and some LEGO!)

Building a Raspberry Pi 4-based weather monitoring solution using Ruuvitag sensors, Azure IoT Hub and Azure Functions

The Raspberry Pi organization announced Raspberry Pi 4 just a few weeks ago. I had to get one, and after placing an order, I received my RPi4 in only a few days. It’s a powerful little computer, with 4 GB of RAM and dual-HDMI outputs. It powers through USB-C, which is an excellent addition. I installed Raspbian on it and connected it to one of the 4K displays I use at my home office. I… Read More »Building a Raspberry Pi 4-based weather monitoring solution using Ruuvitag sensors, Azure IoT Hub and Azure Functions

Building a simple and secure DNS updater for Azure DNS using Raspberry Pi and Azure Functions

Almost exactly a year ago I blogged about building a simple and secure DNS updater for Azure DNS using PowerShell. If you didn’t read that post, it’s a solution for keeping my dynamic IP updated with a static DNS name using a little bit of automation from PowerShell. This tool is useful for when I VPN back home, the dynamic IP has often changed and without a pointer (with DNS) it’s impossible to know where… Read More »Building a simple and secure DNS updater for Azure DNS using Raspberry Pi and Azure Functions
