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.

The GY87 Combined Sensor Test Sketch

Le Thu 15 September 2016

I am intending to use a GY87 board on my Homebuilt VR system. This page describes the connections and an Arduino sketch that tests all of the GY87 board's sensors together and outputs the data to the Serial Port.

A Homebuilt Virtual Reality System

Le Wed 07 September 2016

The project is a work in progress. It describes a home built VR system based on the Quanum FPV headset used for FPV piloting of remote controlled aircraft, and making use of the GY87 10 degree of Freedom sensor to provide head tracking. It is envisaged this will be coupled to a computer running a game engine like Blender, Unity or Godot which will allow the user to build and share their own virtual environments.

A Simple Pressure and Temperature Logger

Le Tue 23 February 2016

This article describes a simple logger arrangement that measures pressure and temperature from two pressure sensors; a BMP180 barometer for when things go right, and an MS5803-14BA high pressure sensor for when things go wrong. This logger will be installed inside the ROV shell in place of the control electronics to record the internal pressure while the ROV is subjected to design pressures in a dive decompression chamber. This will show up if there are any leaks. If the pressure rises then there is a problem.

Arduino Library Collection

Le Thu 21 January 2016

Throughout my various Arduino-based projects I have made use of quite a number of excellent libraries that are not part of the standard Arduino IDE. To future proof these projects against the original sources of these libraries disappearing or updated libraries not working for these projects I have collected up the various libraries I have used and will host them here. In the first instance I would suggest going to the original sources for these libraries for the most up to date versions. The versions I am hosting here will not be updated.

A Simple Arduino Based Logger

Le Tue 19 January 2016

This article describes a very simple Arduino based logger for capturing temperature data and recording it to a MicroSD card. It is intended as a building block for another logger project that will include pressure measurements for use during an in-air pressure test for the ROV project.

Three Arduino Circuits for Temperature Measurement

Le Tue 27 January 2015

So many ways to measure temperature with an arduino! Here is a brief investigation into using three different types of temperature sensor; Thermistors, DS18B20s, and TMP36s. This is with the intention of adding one of these to the ROV circuit so that I know when it has caught fire.

Flex Sensor and Servo

Le Wed 26 March 2014

The sketch described is designed to actuate a servo based on the input from a flex sensor. Because the sketch uses serial communications a button push to start and stop the sketch has been introduced to allow upload on Arduino Uno and Mega boards. An LED has also been introduced to show when the sensor and servo have been enabled.
