Mechanical / Mechatronics • R&D Portfolio

Prototypes, tests, and iteration — documented like R&D.

I build real hardware: CAD → wiring → embedded firmware → testing. This site is structured as scrollable “pages” so each project reads like a short case study.

What I want

Target: R&D / Product Dev

An R&D role where I can build prototypes, validate them with data, and improve them fast. I care about reliability, clean integration, and measurable results.

Mechatronics integration Instrumentation & calibration Prototype → test → iterate Documentation-first

How to read this

Newer → Earlier

Newer projects show current capability: integration, testing, polish.
Earlier projects show growth: modeling, basics, learning trajectory.
Each project uses an R&D-style format: Problem / Approach / Results / Tools.

Scroll: one project = one page • Goal: make it easy for a hiring manager to say “yes”

Newer project

MIDI Controller + Audio Level Bars

Embedded • UI • Prototyping

A tactile controller built for real workflow: knobs/faders + visual audio feedback (level bars). Designed to feel like a finished product, not a breadboard demo.

Photo / demo (add later)

Drop a hero photo or a short demo GIF here later.
Recommended: one clean top-down shot.

At a glance

Inputs: faders / encoders Output: MIDI UI: audio bars Focus: usability

Problem: physical controls + clear visual feedback for audio mixing.
Approach: modular firmware + simple UI states.
Results: (add) latency, update rate, stability notes.

Engineering decisions

IO strategy for smooth fader/encoder reads (debounce + filtering).
UI behavior designed around fast “at-a-glance” understanding.
Mechanical layout optimized for hand feel and spacing.

What to add later

1 wiring photo + 1 enclosure photo
Short spec list (power, update rate, number of controls)
1-minute demo video

Newer project

Thermocouple Temperature Controller (PID Test Rig)

Controls • Test • Safety

Temperature control setup for repeatable heating tests. Built to measure performance, tune response, and document repeatability like a real lab rig.

Photo / plot (add later)

Add a setpoint vs measured plot here later.
This is hiring-manager gold.

R&D framing

Problem: stable, safe temperature control with measurable performance.
Approach: thermocouple sensing → PID → SSR/driver → heater.
Results: (add) overshoot, settling time, steady-state error.

Thermocouple PID tuning SSR / power stage Repeatable tests

What I learned

How noise & sampling affect control stability.
How to tune for “fast but not sloppy.”
How to document results so they’re credible.

Next milestone

Add logged data export (CSV) + plotting.
Define safety limits and fault behavior.
Write a 1-page test report (spec → results).

Newer project

Smart IV Bag / IV Pole System

Mechatronics • Medical-style device thinking

A mechatronics concept focused on practical usability: sensing + controls + a clear UI. Structured as a product-like system: requirements, constraints, and validation plan.

CAD / prototype photo (add later)

Add a CAD render or prototype photo here later.

System overview

Problem: improve monitoring + usability.
Approach: load sensing + actuator concept + UI.
Results: (add) accuracy, repeatability, user workflow.

Load sensing Motorized mechanism UI + alerts Design constraints

Design constraints

Stability and safe motion (limit switches / stops).
Battery life + charging considerations.
Calibration and drift over time.

Validation plan

Bench test load readings across multiple weights.
Repeatability tests (same weight, multiple trials).
Motion cycle test (wear / reliability).

Newer project

Autonomous Drone Build

Systems • Integration • Iteration

Drone platform work focused on real-world reliability: component integration, tuning, packaging, and a test-driven approach to improving flight behavior.

Flight / build photo (add later)

Add one clean build photo + one flight clip thumbnail later.

What matters for R&D

Problem: stable flight + repeatable performance changes.
Approach: tune parameters, log changes, validate with flights.
Results: (add) “before/after” behavior and settings summary.

Integration Tuning workflow Packaging Testing

Highlights

Repeatable tuning process (changes tracked + validated).
Wiring and mechanical packaging improvements.
Focus on “works every time,” not “works once.”

Add later

Short checklist: build, setup, tuning steps.
Table: change → expected effect → observed effect.

Earlier project

Automotive Trim Piece (Design + 3D Print)

CAD • Fitment • Iteration

Practical CAD-to-physical part workflow: measure, model, print, test fit, revise. This project shows early “real-world constraints” thinking.

Before/after (add later)

Add a “broken/stock” photo and your printed part installed.

Process

Problem: replacement / improvement part that fits and holds up.
Approach: measure → CAD → prototype prints → revise.
Results: (add) fitment notes + print settings/material.

Measurement CAD revision FDM printing Fit testing

Growth point

This is where I learned iteration discipline (small changes, retest).
Fitment taught tolerance and real-world variability.

Upgrade later

Add a dimensioned drawing snapshot.
Add a “rev history” note (Rev A, B, C improvements).

Earlier project

3D Modeled Water Pump

CAD • Mechanisms • Learning fundamentals

A modeling-heavy project that shows fundamentals: part breakdown, assemblies, and mechanical reasoning. Great for demonstrating growth from CAD skill → integrated mechatronics later.

Render (add later)

Add 1 clean render + exploded view if you have it.

What it demonstrates

Understanding of components and assembly relationships.
Better modeling practices over time (naming, constraints, structure).
Add: what you’d do differently today (DFM, tolerances, sealing).

Assemblies Mechanisms CAD discipline

Lessons learned

How to structure assemblies cleanly.
How to think about motion constraints and interfaces.

Make it stronger later

Add a simple section view or interface detail.
Add a short “requirements” paragraph retroactively.

Earlier work

Early CAD Models (Growth)

Show progression

A curated set of earlier models to show growth over time. Keep this section selective: 4–8 items max, each with one sentence.

Gallery placeholder

Later: add a simple grid of images.
Best format: 2×3 grid with short captions.

How to present growth (do this)

Label each: Year / Context (class, personal, client).
One line: what you learned (constraints, tolerances, assembly).
End with: “What I do differently now.”

Example entries (replace later)

Bracket model — learned constraints & clean sketches.
Assembly practice — learned mates and motion planning.
Fitment part — learned tolerances and iteration.

Why this helps hiring

Shows trajectory, not just isolated wins.
Signals coachability and learning speed.
