Carnegie Mellon Silicon Valley Solar Controls and Diagnostics Testbed.
We won a DoE grant to model and predict failures in solar arrays. After spending about six months helping build MATLAB simulations, I was tasked with designing a solar array for the roof of the CMU-SV lab. A task that started out overwhelming, but is probably my proudest work: our 24-panel, pole-mounted 1.2kW array, instrumented with 900+ temperature sensors and a weather station, wired in four parallel strings of six panels each.
I learned not only about photovoltaic modeling and simulation, but also how to use Google SketchUp, how to work with high voltage wiring, electrical code, contactors, wirenuts, disconnect switch boxes, programmable electronic loads, I-V curve tracers, DS18b20 digital temperature sensors, and that your feet will get sunburned if you spend all your time in flip-flops on the roof.
Array, and data from the array, was also used as part of a bi-coastal Photovoltaics course in Spring 2013 at Carnegie Mellon.
We also flew a 1/8th scale Piper Cub nicknamed "Bumblebee", and for one summer, sailed a radio controlled sailboat.
Even now, looking back - this was such an amazing job. So much of my confidence with hardware and integration, I learned from Corey, Vince, Ritchie, and Mark. I was hired on to do electrical design, but because we were such a small team, I also got to work on everything else - software, simulation, drilling, gluing, soldering, checklists, calling vendors, data analysis, you name it. The custom avionics box was my project, and unfortunately I never got to see it fly.
We test flew out at the Moffett Field runways for the EAV.
We were also part of the inter-governmental-agency team that deployed robotic sensing and analysis robot
and software to assist Santa Clara County District Attorney's office in cold-case murder investigation in 2010.
Stanford OSA Laser Harp and the Piezoflower Garden
Laser Harp (not shown): Designed, built, and presented Arduino-powered Laser Harp for
booth at San Mateo Maker Faire, May 2013; displayed again May 2014.
Piezoflower Garden: Interactive Sound art installation: a bouquet of metal flowers built around piezoelectric disks that sits
quietly until a passerby taps or plucks the petals, which produce unexpectedly powerful sounds. Produced for Music
250B: Interactive Sound Art, Winter 2013.

Stanford DroneGames 2013
Placed first out of 40+ teams in a 12-hour hackathon, designing and programming
an autonomous camera-guided quadcopter drone that would track and pop color-coded balloons.
