Lab & beyond
Sometimes words are not enough. Here is what the work actually looks like.
Measurement Setup
I designed both the LED holder and sample stage in Fusion 360 and 3D-printed them in-house. The fixed geometry eliminates variable contact resistance that made earlier free-hand setups unreliable. This rendering was made in Blender for the research paper figure.
Device Under Test
A 5 × 5 mm² silicon wafer coated with a CdSe:GQD composite thin film. The silver paint contacts are applied by hand under a microscope — each contact placed to ensure flat, repeatable electrical connection across every measurement run.
Hardware Build
A custom-built automatic temperature-controlled fan system. The control unit features toggle switches for resistor and thermistor inputs, housed in a clean enclosure. The fan itself is mounted on an articulated 3D-printed arm, showcasing a practical integration of electronics and mechanical design.
Software Build
A zero-code mobile frontend built with Google AppSheet to triage events extracted from my inbox. A background Google Apps Script uses Mistral AI to parse emails and log actionable events into a Google Sheet database. This app lets me quickly review and approve events with a swipe, pushing them directly to my Google Calendar.
More images will be added as the work progresses. Every photograph here is from a real experimental session — not stock.
