The Cacophony Project is completely open source. The hard/software component can be used gratuitously in accordance with their licenses. Given this, how can you possibly create a business from it? The short answer is the same way people build businesses selling water
A new device with both heat and infra-red cameras connected to the cloud looks to be a more automated and sensitive tool for monitoring predators
Just a quick shout out to Spark. Some folks at Spark heard about our project and immediately offered to help. From the first meeting we walked out with some sim cards with free data to play around with. No paper work, no delay, just a quick “yeah that sounds good – go for it”. We can see lots of ways their team and services can help accelerate this project over time.
Many thanks to Andrew Pirie, Paul Deavoll and Andrew Leckie from Spark.
Our design philosophy is to create a device that can:
- Identify 100% of the predators out there – unless you can do this there is no way to know how well you are progressing (looks like we are very close to a device that can do this - link)
- Lure 100% of the predators – there are lots of possibilities with using digital lures (link)
- Kill 100% of the predators
This project initially started with the goal of creating a tool to dramatically improve monitoring how the environment responds to predator eradication. In New Zealand we are lucky that the bird song is literally the canary in the mine:
Firstly, we love the government’s new announcement of the target to be predator free by 2050. Bold, ballsy and just the sort of thing New Zealand should do. What we would like to do here is a little analysis of why we think it will happen sooner than that.
Moore's law is the observation that, over the history of computing hardware, the number of transistors in a dense integrated circuit doubles approximately every two years. This has morphed into a remarkably consistent observation that Information Technology either doubles in performance or halves in cost about every two years
Trapping, poison, hunting, and fences have all been turned against pests to help prevent the ongoing slaughter of New Zealand birds. However, we know that current trapping methods aren’t cutting it. As part of our experimenting we have had video trail cameras pointing at existing (traditional) traps to measure how well different digital lures work. What has completely surprised us is that as little as 1% of the time that a possum turned up on camera a trap was activated.
The goal of this project is to develop tools that eliminate 100% of predators. To do this the device must therefore be able to detect 100% of predators. Chew cards and tracking tunnels can miss over 60% of predators. Standard camera traps are thought to miss as little as 5% of predators due to not starting fast enough or the light/sound scaring animals away. There are also issues with false positives making it difficult and time consuming to filter the videos

The aim of this project was to see if the latest Machine Learning (Artificial Intelligence) tools could correctly identify the difference between rats, stoats, possums and others from videos collected from the field. This project was given to a set of 28 final year honours students at University of Canterbury.
Summary of the technical features of the project and how we are progressing with each.
We have started testing digital lures with a camera to observe the different rates of animal interactions. These tests are aimed at possums for the simple reason that our property is infested with them. Our initial impressions are...
Machine learning (a branch of Artificial Intelligence) is the general term for how computers learn to recognise patterns. Machine Learning has become very powerful with the advent of inexpensive computer processing and the explosion in available data enabled by the internet and cloud computing. Capitalising on all this data, deep neural networks have recently shown order-of-magnitude improvements in tasks such as automatic speech recognition and computer vision.
This project humbly began by doing a bit of local pest eradication on our small property in Akaroa. After a couple of years I’m sure the bird volume has gone up, thanks to the Akaroa community all doing their bit. I thought this was cool but how could I know for sure? From investigating the manual methods it seemed like computers would be a great way to measure bird volume and record trends over time.
The Cacophony Project has been founded on the idea that some problems are too big, too complex (and too important) for any one commercial entity to solve. For a really huge problem like restoring NZ's native ecosystems, innovation is needed from all over the place. We recognise that a few experts can contribute what they know at low cost to themselves but at high value to the rest of us.

We start our first blog with what sounds like an outrageously bold claim; that it is possible to make eradication of predators in New Zealand 80,000 times more efficient. Technology could make it possible...
