Why do attend a hackday?

• Prizes• Learning new things• Free pizza, coffee and beer• A Challenge• Show off their skills• Fun

Hackday Tips

• Create a repository on Github/Bitbucket

• Give all team members access• Encourage code sharing• Briefly document your work – wiki• Take photographs• Have fun!

The Oxford Flood Network

• Guerilla sensor network• Community involvement• A number of cheap river level

monitors• Basement/cellar flooding monitors• Make data freely available• Free to build your own apps

Sushack #1

• Single day event in Oxford, Nov 2013• Sponsored by 2degrees• Sustainability and environmental

theme• Around a dozen attendees• Mix of skillsets• All wanted to work on Flood network• End to end system demonstrated in a

day!

Early field trials

River level Sensor Version 2

Version 2 field trials

Open City Competition• Run by Eyehub• Final at House of Lords• Prizes!

Internet of Things Showcase

River level Sensor Version 3

River level Sensor Version 3

Funding the project

• Prototype sensors funded by ourselves

• Applied to Technology Strategy Board

• Nominet are buying first 10 sensors• Parts cost £130

Oxford TVWS Trial

• Love-Hz running Ofcom licensed TVWS trial

• Equipment bought by Nominet• River level sensors provide the

application• Other sensor applications being

devised• Nominet building back-end system• Sensor data will be freely available

WutheringBytes

• A festival of technology in Hebden Bridge

• Talks and workshops• Took sensor kits, interested people

built them• Deployed sensor

CDE Catapult

• Connected Digital Economy Catapult• 7 Catapults covering different areas• Setup by Technology Strategy Board• No funding but support & expertise

via technology and innovation centres

• Organise events for startups/SMEs• Oxfloodnet to exhibit at Euston

showcase opening in November

The Future

• First 10 sensors soon to be deployed• Work to improve radio range• Develop front end web applications• Make kits available• Alternative sensors• Other Cities• Can you help?

Lessons Learnt

• Take photos and document your work• Show people, talk to people• If it works on the desk, will it work

under a bridge?• They make waterproof sensors for a

reason!• Have fun and enjoy your project.
