Concocting the datasniffers
Below are a series of photos, diagrams and videos from various stages of the datasniffer’s construction. These are displayed in roughly chronological order, without attempt to organise by theme or area of work. This is to give a stronger sense of the process of making, to contrast with the slightly more schematic treatment in the commentary.
The land registry datasniffer, an early prototype created in spring 2018
This version used the ‘Price Paid’ dataset from the UK Land Registry. It allowed you to detect house sales.
Fritz of the land registry datasniffer circuit
This diagram was created using Fritzing
Diagram of software setup for land registry datasniffer
Concept drawing of the London Development Datasniffer
Produced for Batallion (published by Sidekick Books).
Early construction of internal circuitry
First build of the London Development Datasniffer
Early version of noise making contraptions
First datasniffer assembled, second in progess
Early group trial of the datasniffer on a bat walk in summer 2019
A visit to One Tree Hill, as discussed in Chapter 7 of the commentary.
2019 versions of the datasniffers on display at the Common Ground Festival
Pictured with bat detectors and two high frequency rattles I made for demonstrating how the bat detectors work.
Final version of noise making contraptions, mounted on a frame
Attempt to diagram the second version of the datasniffer’s signal logic
Not only was the second version of the signal logic too complicated to describe (as discussed in Chapter 6 of the commentary), it was apparently too difficult to diagram as well!
A short video of some field tests of the datasniffer in summer 2020
Map software for testing reliability of datasniffer’s geolocation
This map was created to account for the datasniffer’s strange behaviour. It is discussed in Chapter 6 – Sketch 1.
