So I’ve had a win with the changes to my soil moisture sensor. The reduced battery consumption has meant I am getting the battery to charge even in reasonable low light conditions. I hope to add deep sleep soon and hopefully reduce the solar panel size needed. Here is a 5 day graph showing the […]
I have finally finished configuring my soil moiture sensor and worked out the kinks with power consumption. It currently works by using a 2N2222 transistor to turn on the sensor for a few moments to get a measurement and then turning it off again to conserve battery. I wrote a quick #ifdef to allow me […]

Introduction My website opens3.net is built using Kotlin (Ktor), NGINX running on a FreeBSD droplet. The micro services now consist of the following (all written in Kotlin and Perl): Content Management System Weather warning SMS bot (sends weather alerts it parses from BOM) Weather warning back-end Log file processor and IP to location converter for […]
This is a React Native app for my Air Monitor device that I built. It uses Victory graphs and connects to the Characteristics exposed on the Air Monitor. Features: Real time graphs 24 hours graphs Max for TVOC and CO2 Real time measurements The source code is on my GitHub.
I just finished building the latest version of my air quality monitor. It now includes total VOC measurement as well as CO2. I am happy with the final product. Build your own here: https://www.thingiverse.com/thing:4126483 Now I need to spend time building the PWA.
Well I have been pushing myself pretty hard and there are consequences for everything. I was drinking way too much coffee and have decided to quit as a result of the negative health effects. I think it will take a while to get used to living without caffeine since I have been consuming large amounts […]
