Better Hardware, Better Research

Jo Walsh

UK Centre for Ecology & Hydrology

April 9, 2025

Overview

  • Software Sustainability Institute Fellowship for 2025
  • Open Source Hardware for Environmental Monitoring^WSensing
  • UKCEH course on Field Electronics and Sensors
  • Short-term problems, long-term aspirations

The SSI Fellowship Scheme

  • Not just for Research Software Engineers
  • Focus on community building and organising
  • £4000 budget available for expenses
  • Doesn’t, however, cover one’s time
  • 2025 Fellowship Cohort

Field electronics and sensors

  • In-house Field electronics and sensors training
  • Developed originally by Milo Brooks in Bangor
  • Delivered by Rob Nicoll and Neil Mullinger in Edinburgh
  • Intensive two days, beginner-friendly

Course curriculum

  • Electrical and electronic theory
  • Breadboard practise, measurement with multimeter
  • Soldering practise, kit building
  • Working with the Arduino IDE
  • LoRaWAN intro, publishing to Things Network
  • Construction and weatherproofing

Course takeaways

  • It’s a really good, densely-packed course
  • I need to run through it all again on my own!
  • Invaluable tips from field service experience
  • Beautiful simplicity of some of the sensing techniques
  • Subtleties of interpretation in dataloggers

A real strength for UKCEH

  • UKCEH has a lot of good people doing this work
  • Instrument and field engineers, and also researchers
  • Engineering Workshop skills and tools in Wallingford

“Better Hardware, Better Research”

  • Better Software, Better Research
  • Better Training, Better Production, Better Software
  • Better Access, Better Review, Better Software
  • Better Recognition, Better Software
  • Better Funding, Better Software
  • Better Software, Better Science

Better Software

How can these principles apply to research hardware?

  • Proposal to coordinate a workshop series
  • Bring together field researchers and hackerspace inventors
  • Collaborative, craft-based workshop model
  • Deepen connections to the Open Science Hardware community

Theorising - the up side

  • Sensor “innovation” by bringing research questions to inventors
  • Cheaper, more accessible and reproducible research
  • Unexpected science by collecting many kinds of sensing
  • Join more dots between “citizen science” and long term monitoring
  • Funders can build in incentives, as they do for open data and code

Theorising - the wider upside

  • Low-power, local networking for sustainability and resilience
  • Monitoring information where it can be acted upon
  • Business generation for small fabricators / factories
  • Skills development and traininng with many applications
  • Decomputing

Theorising - the down side

  • Yet More Data and data waste
  • Data First, Questions Later
  • Certification and SLAs need more social infrastructure
  • Unintended monitoring purposes and data privacy

Theorising - the future

  • It’s easy to end up at more instrumentation and surveillance of living things
  • Spread of industrial control systems into more of our environment
  • Investment flooding towards AI, where there are simpler alternatives
  • Consideration of whose hands the data and techniques are in
  • Alternatives to putting it all on the internet?
