Extreme Aquarium Automation

- Exposé on home-made, handmade, aquarium automation setup

This post describes my current aquarium setup, in particular, the technical, custom designed parts of it. There is a lot of monitoring and control going on; though virtually all of it is hidden behind the scenes, as my aim has always to create a natural looking environment. An aquarium is an eco-system, some aspects of it can stay in natural balance with maintenance, and other parts require active control. Things are more complicated with plants - I recently have become more serious about growing plants.

Introducing Polestar

I’m not really sure why it’s taken so long but I’d like to introduce Polestar. I actually first started the project back in 2014. I got a couple of early adopters in January 2015. Since then it’s been used quietly without much fuss with a few updates along the way. Background I got the idea for Polestar at the 2014 Good Things conference in Bath, UK. I noticed a repeating pattern from the speakers - a kind of reference Internet of Things architecture.

Building Radar Speed Camera and Traffic Logger

- with a Raspberry Pi

There is a major update to this article, please see this later post Radar Speed Camera Rebooted. I’ve always been interested in connecting things up to computers that they were never designed for. I could reminisce about my first drawing capture arm that used captured the two joint angles with potentiometers and used them to control the pulse width oscillators that fed into the cassette input on a ZX Spectrum.
