Compact Bio-Tester Design, CADD design
Budget: $25 – $50 AUD
Biotech Test Device
This is the first stage of a small, proof-of-concept biotech tester that fits everything on a single PCB mounted within a compact enclosure. The immediate priority is an accurate 3-D layout of the internal layout with optical paths, small heater block snd selection of specific critical components that impact the CADD layout.
This is so I can confirm the design, space claims and streamline the optical path before committing to electronic design as a later stage.
Design to include:
• Core electronics: a low-power microcontroller, USB-C for power/basic comms, two I²C temperature sensors, two analog light sensors, four momentary buttons, a four-position DIP switch, status/power LEDs, and a 2 W resistive heater bonded to a 1 cm³ aluminum block (max 70 °C).
• Outputs: 2-inch display plus the LEDs and heater.
• Inputs: the sensors and buttons listed above.
• Mechanics: light pipe guiding the optical path, single PCB mounting, and a simple outer shell.
Im am looking for an experienced product design CADD designer working in SolidWorks or Fusion 360 to build up a the functional optical path and component layout model that places parts within an accurately defined assembly including a small heater block , snd parts mounted on a closely integrated OCB.
Collaborate with regular review and comments on screen shots and images.. building up the design in iterations.
Share native CADD files to assist review and records of iterations as we progress.
Deliverables
• Native CAD files (SolidWorks or Fusion 360 archive) of the full assembly
• Share Annotated screenshots highlighting optical layout., and heater component layout for discussion and review.
Approx 10 to 15 hours per week over a number of weeks. Work will be limited by review and feedback on iterations as we build up the design.
Don’t expect to go off and design the whole thing in one go as there are lots of interdependencies and design constraints to resolve. Design will require time and iterations to resolve and improve. This is not a styling or product concept project. It is working on functional internal detail and building out from that.
