An Arduino Based Solar Water Heater Controller

Le Wed 01 March 2017

We were less than thrilled to find a power spike had gone through the house while we were away on holiday leaving our Solar Water Heater Controller's brains a bit addled. It was never a particularly good controller anyway and the suppliers are a pretty "prickly" bunch when it comes to trying to get information from them, so this was an opportunity to do what I had been meaning to do for a while. This article describes a home built solar water heater controller based on an Arduino. Now the set points are adjustable and able to be tuned to the local conditions. What more could you want in a solar water heater controller?

The Solar Water Heater Controller in a Perfect World

Le Wed 01 March 2017

This article describes the lovely rosy perfect world solar water heater controller project where we are untroubled with things such as non-perfect installation, the loveliness of quiet power supplies and things. Here you will find the circuits, coding, and associated project information. However don't get me wrong this is the perfect place to start making a real world system to suit any solar water heater controller situation.

Battery Discharge Tester

Le Tue 28 June 2016

I have quite a few rechargable AA and AAA batteries kicking around that I'd like to use in various projects, but I know a number of them are pretty crappy. This article describes an Arduino based device that conducts a controlled discharge of the battery cells and logs the voltages. By analysing the discharge curves the battery health can be assessed.

12V Lead Acid Battery Monitor

Le Wed 03 February 2016

Both the ROV base station and the FPV base station I use are set up to be powered by a 12v battery. I was a little concerned that running these rigs for extended periods was exhausting the battery and dropping it to levels that could potentially cause it permanent damage. I needed a battery monitor that could warn me when I had used more than the battery could comfortably deliver. This article describes the 12V battery monitor I devised for the purpose.
