The Raspberry Pi solar data logger project is now live and is the latest version of our previous data logging systems using Arduino and Android + IOIO board projects.
The data is used on a custom reporting website on home.briandorey.com and...

To make it easier to connect the various cables to the new Raspberry Pi ADC board we decided to make a second PCB with header pins to connect to the ADC board and take these to screw terminals. Also we wanted to have a temperature controlled...

The code sample below shows how to read the ADC values from the MCP3428 16-Bit, Multi-Channel Analog-to-Digital Converter with I2C™ Interface and On-Board Reference by Microchip via I2C on the Raspberry Pi using Python.
The code on this...

The original plan for the Analog-to-Digital Converter was to use the Dallas 1-Wire system and use the DS2450 1-Wire Quad A/D Converter which was advertised as being a 16 bit device but after buying two of the chips which are around £5...

Currently working on a new I/O board add-on for the Raspberry PI computer. The PCB will have 8 16bit A/D inputs which are connected via buffers to the I2C port on the Raspberry PI GPIO port. There will also be a built in 5V power supply...

The plan to use an Android phone and IOIO board to log the solar data has been abandoned after repeated failures of the IOIO boards to run for more than 24 hours without crashing or resetting. It maybe that I have purchased 2 faulty boards,...
