Medispenser
An automated pill dispenser for clinical point-of-care use. A scanned RFID card looks up the patient's prescription; three stepper-driven slotted-disk hoppers dispense the correct combination, with an Arduino-controlled LCD guiding the nurse or doctor through the workflow.
Built with a team of four for Cornerstone 2. The final prototype achieved 100% dispensing accuracy across 100 trials of three patient prescriptions, exceeding the 95% design target. Total build cost: ~$95 — orders of magnitude below commercial hospital dispensing cabinets.
My contribution was the SolidWorks CAD for the hoppers and backing board, all laser cutting and 3D printing, and the standardized 3D-printed test pills.
