I have been designing and building a weather station to put in my garden at home. It will be a one-off project so I don’t need to compromise on cost – instead, I want something that will be reliable and, if anything, slightly over-engineered. This particularly applies to the power source – it has to… Read more: A No‑Compromise Solar Power LiFePO4 Solution for Arduino Projects

If, like me, you use HBS3 to make automatic backups from one QNAP NAS box to another then you may occasionally find they failed and the reason for the failure is that the RTRR service on one of the NAS boxes has disabled itself. I was getting this problem at least every week and it… Read more: QNAP RTRR Service is disabled after reboot

My objective was to build a battery powered environment monitoring station using an Arduino. It might be an outdoor weather station tracking temperature, pressure and humidity or something to track indoor temperatures. Long battery life was a primary concern. In a previous article, I investigated how to minimise power demand and select the best combination… Read more: Nano 33 IoT: Testing with solar power and BQ25185

In this article, I will describe my attempts to minimise power demand in the Arduino Nano 33 IoT and select the best combination of batteries to use. My objective was to build a battery powered environment monitoring station using an Arduino. This might be an outdoor weather station tracking temperature, pressure and humidity or something… Read more: Nano 33 IoT: Testing battery options and low power mode

I had a fairly simple objective – to build a battery powered outdoor weather station using an Arduino. The very first step, choosing which Arduino board to use, proved to be more complex than I expected. In fact, the array of parameters in my selection matrix kept growing over time as my knowledge increased during… Read more: Selecting the right Arduino board for battery powered operation
