Aeroponics
I was responsible for lighting, irrigation, and HVAC
Racks were adjustable for different crop heights
I packaged HVAC, CO2, and fertigation systems under the floor vents
A transparent dual-layer membrane enclosed the crop growth environment
Photovoltaics
Using mirror film to increase solar cell output
Cell protection and mounting
Cell arrays and connections
Up to 27.6W max capacity, plenty for phones and portable batteries
Systems take solar energy and deliver 120V AC outlets
Harvest daylight to electricity

Avionics
Potting (using epoxy to protect electronics) a data logger PCB directly to its box. This yielded a natural frequency that was too low.
Incorporating a seal, enclosure, and mounting legs for the data logger circuit. The SD card is still protected by epoxy potting.
At 200g of force, the maximum stress is only 13.1 MPa, compared to the yield stress of Aluminum 7075 of 503 MPa.
At 50g RMs of random vibration, the maximum stress is 30.7 MPa, still small compared to the yield stress of Aluminum 7075 of 503 MPa.
Added improved mounting features, and an o-ring for better sealing.
The final design, with separate seal screws from the mounting screws, a heat sink to cool the microchip, better mounting features, ribs and fillets.
