Made first draft of block diagram showing connections between sensors, Raspberry Pi 5, Pi Pico, SSRs, power resistors, servo valves, and cooling components
Block Diagram v1
BOM Draft
Made first draft of BOM listing major components based on block diagram and physical assembly, to be updated
CAD Models of Liquid Cooling Components
Found online CAD models of radiator, fan, and water block
Altered radiator model to better match actual part
Created CAD models for pump and reservoir based on product photos and references

Initial CAD Assembly of Cooling Loop
Built an initial CAD assembly of liquid cooling loop with component models
Used linear motion rods and connector system for structural frame

Revised CAD Assembly of Cooling Loop
Updated initial assembly to accommodate sensor placements, including radiator intake/exhaust temperature sensors and mounting space for Raspberry Pi 5 and supporting components

Schedule & Progress
Currently on schedule
CAD modeling, assembly, block diagram, and BOM align with Gantt chart
Next Steps
Iterate on block diagram
Expand BOM to include linear motion rod and connectors
Start purchasing off the shelf parts in order to update CAD assembly with corrected dimensions and order 3D print/laser cut parts
