I have lost my way in the world of software and its now time to brush the dust off my interest in building hardware
In this post I bring together three previous projects into a finished solar-powered wireless sensor network for the garden shed — gateway, end node, and battery monitor, talking over XBee. It's a long one, covering the design decisions and lessons learned, plus a technique I picked up from a KiCon 2024 talk: using KiCad to … Continue reading Wrapping up the Remote Power Sensor
Developing firmware for an embedded remote sensor that needs to adhere to a specific protocol has challenges due to the limited resources and the complexity of the implementation. Experience on a previous project (a remote sensor gateway) demonstrated how Test Driven Development could assist when working on complex systems. This write-up describes the approach used … Continue reading Developing a Remote Sensor Firmware using Test Driven Development
