Cartesian fishing game
I led CAD and mechanical layout for a team-built fishing game that combines X-Y positioning, a motorized Z dip, magnetic pickup, and a rotating target board.
Classroom demonstration completed with X-Y-Z control, magnetic pickup, and all three game rounds working

Cartesian pen plotter
Our team developed a single lead-screw stage into a two-axis plotter and used G-code to test coordinated motion and pen actuation.
Produced recognizable square and circular traces; accuracy and repeatability were not measured

Acrylic truss design and test
Our three-person team analyzed, built, and load-tested an acrylic truss after iterating its geometry in MATLAB.
Final MATLAB prediction: 46.59 oz; physical build met the 16 oz minimum

The Deskinator
I wrote the Arduino navigation firmware and helped assemble and redesign an autonomous desk-cleaning robot.
Documented suction trial: 72 of 95 rice grains collected

Room temperature monitor
I programmed the sensing and alerts, assembled the electronics, and packaged the circuit in an ABS enclosure.
Displays °C/°F and alerts outside 60–75°F

Rocket nozzle
I sized the flow path, modeled the nozzle and adapter, and checked the pressure load before fabricating a resin prototype.
Pressure FEA: minimum factor of safety 2.12
