Design a polymer casing for the sensor. First iteration
3D modeling, with Daniel
Created diagram of electronic PCB for the soil moisture sensor
After the discussion with Gregory. Communicated it with the team.
See it also in the main doc.
3D model the casing for the second prototype, with Tibi
Worked on sourcing and documenting components for the sensor, mostly light source and detector. I documented that in the R&D doc.
This was done on Frederic's input on light sources and detectors.
I also created an Instructable document. For now, it is just a placeholder, but the idea is to produce a doc to distribute to open source communities.
Looked into best light sources and detectors for the sensor, documented this in the R&D doc.
Order: Work order 149 for Make Optical soil moisture sensor prototype due: 2015-01-29
NOTE: you need to create specific design processes here (Design electronic, mechanical, optical, software or other)
This design stage focuses on the product itself and feeds on the Design considerations stage. Designs can be of multiple types: mechanical, electronic, optical/photonic, etc. Designs are Resources in the NRP-VAS system, and are represented by some sort of design file: a sketch, a CAD file, link to a software repository, etc.
INPUT: all from Ideation and Design considerations
OUTPUT: product design - file(s), can be multiple
Distinguish 2 levels of design at this stage:
1- System Level Design: Definition of product architecture, decomposition into subsystems and components, and preliminary design of key components. Plans for the production system and final assembly; Outputs: Geometric Layout of the product, a functional specification of each subsystems, and a preliminary process flow diagram for the final assembly process.
2- Detail Design: Complete specification of geometry, materials, tolerance of all unique parts; identification of all the standard parts to be purchased from suppliers. Process plan established and tooling designed for each fabricated part within the production system. Outputs: Control Documentation for the product - drawings or computer files describing the geometry of each part and its production tooling, specs of purchased parts and the process plan for fabrication and assembly. Three Critical issues: Materials Selection; production cost; and robust performance.
Desired design characteristics
* Shareable (the sharing economy)
* Modular (perpetual products and customizable) - see this link about a specific effort to define a standard for scientific parts.
* Interoperable (standards)
* Socializable (offer value through social interactions and communities)
