Summary topics discussed
- What re people using what they’re using
- Documenting the Hardware design processes and component selection
- Can we build an online community: who’s going to lead that?
- HW for actual farmers not geeks having fun…
- Imaging hardware
- Lack of documenting hardware design process is a problem - information isn’t readily available
- Can we make a RIOT channel/thread on the forum maybe?
- Maybe further down the line we could create webpage/wiki/gitpages?
- LoRa coverage mapping experiments in Ag contexts are needed
- Could we group purchase some expensive components for cost saving
- If you are interested in hyper spec dev watch the forums for Greg to post
- There’s a missing link between Ag and engineering even though lots of people are working on it - missing link due to documentation?
– Also sometimes it’s actual language barrier (english/french named)
– Farmhack/OpenAg/ what else can be done to encourage connections?
- People have to want to do it
- Look at Vinduino: tinker/hobby farmer (viticulture) building stuff
- Anyone want to geek out on ADC/VReg etc specs - David would be keen
- New technologies people are working in
- The process of developing hardware
Attending, key skill/current project, interest from the session:
- Brian Davis: Data processing, connects hardware team with end user, interested in best pracitces
- Ned Horning: Tinker, imaging hardware
- Gwen Jones: Works with international farmer communities, lots of mechanical open hardware experience
- Will Szal: RegenNetwork, monitoring technologies, what hardware people are using
- David Forester: Forum convener re HW, Tinkerer, has a wiki to share, studies spec sheets, wants to understanding component selection process
- Patrick Oconner: HW testing and documentation, Event planning, polays with SOCs, embedded SW
- Jane Wyngaard: Drones, EE
- Daniel Fisher(aka Ken): Open Source HW, USDA, open hardware for new sensing and monitoring systems, arduino, data logging systems
- Frank Rose: Software, ThingsNetwork LoRa, Arduinos
- Samual Oslo: Farmers, Working with Farmers who are interested in HW developed in Quebec, interested in dev process/sharing process
- Reginald Fletcher: Hyper spectral and rmote sensing/camera systems
Process of selecting components
- The front person often in the dark when demoing gear to users about why xyz decision was made re the hardware
- We need project metadata
- Can we setup a monthly call/mailing list?
- Crowd supply process: they have continuous blogging of their process and decision making often to keep their supports informed
- Personal Wikis
- In industry often decision is driven by convenience (which chip is in my database for schematic design/available from my supplier)
How do we disseminate HW/info/methods/…
- Time line from solution to publication…
- Git pages
- SW thinks code documents itself - less easy for HW - schematics semi self documenting but requires high level of expertise to read
- LoRa/LoRaWAN for rural areas? - Long Range, Low data rate, Low power - We need emperical data about range etc in forestsfarmland/.... - Ken using some for local farm work in dev - Others using cell but many areas don't have cellular signal - Prices: ~$10-40 - Coverage mapping of LoRa needed - ISM bands so bands can't be bought - Protocol has features to mitigate interference etc - Proprietary chip - Protocol is open - Runs in an unregulated space - 915MHz in US/856in EU
Problem: deploy cameras in a field to watch corn growing and note when leaf curls to detect water stress - possible? - concluded yes
- Could and/or use reflectivity/other
- Should be do-able
- HW is the easy bit of this project - relatively speaking
- will be very useful for predictive imaging - see things the human eye can’t
- Single pixel camera version for low cost high res solution
- Needs a low cost random gridding mechanism
- Can lower your noise floor using the random mask
- Greg is going to build one in the next year (we think) - anyone want to be involved watch the forum
- Uses: differentiate between vegetation (alien detection), soil science (distinguish between different minerals)
- There are new multispec sensors available for low cost (AMS sensor) ~$25
- Hyper or not for Ag specifically? - still evolving - One place they'd definitely be useful perhaps is for predictive imaging- Can drone see something before humans? (needs hyperspec cameras) - no fly zones: could use kites, balloons
HW for actual farmers
- Alot of tech geeks with cool gear but what about actual tech for Ag:
- Alot of us are solving our own problems
- How to match problem to engineer?
- Some forums for facilitating connecting engineers to farmer problems: FarmHack, OpenAg,…others?
- Tinkeres are seeing tech from say home automation/energy monitoring and choosing to apply it to Ag problems - there’s a translation barrier here
- Farmers are probably best at looking out at the world and seeing if they can mod things for Ag
- There’s a missing link to documentation…
