3D CAD Modelling
This is an incubator designed to be retrofitted onto an existing record player. Since our goal is to represent the growth of cultures through audio, the design criteria required:
- Detection: Visually detect the growth of an entire petri dish (the size of a vinyl record) using a camera without occlusions
- Compatibility: Ensure the heat generation from the incubation will not degrade the enclosure and produce unwanted molecules/gas
- Accessible: Easily change out by-hand the culture plates; easily monitor the plates
Based on the specifications of our camera module, we calculated the minimum height that is required in order to image a 12” petri dish based on the field of view of our camera.
Specifications of our camera module:
- Angle of View: 54 x 41 degrees
- Field of View: 2.0 x 1.33 m at 2 m
- Full-frame SLR lens equivalent: 35 mm
- Fixed Focus: 1 m to infinity
- Max frame rate: 30fps
We confirmed our calculations by conducting an initial test:
