I lay out circuit boards and write the firmware that runs on them. The board in the photo is a drone flight controller I designed in KiCad and soldered myself.

My flight controller after hotplate reflow. It's in the airframe now, and it flips the moment it lifts off. Read the build log

About me

Ethan Suttor
Senior at UofL's J.B. Speed School of Engineering

I'm a senior electrical engineering student at the University of Louisville's Speed School, where most of my coursework has pulled me toward the hardware side: embedded systems, FPGA design, and VLSI physical layout.

The flight controller started as a test: could I take an embedded system from a blank schematic to something that actually flies? It doesn't fly yet. The build log has everything that went wrong along the way, including the parts that make me look bad.

Bench test: one motor at full throttle from the FlySky transmitter

Custom Drone Flight Controller PCB

An STM32F405 flight controller for a 4S FPV quad, running Betaflight on a target I wrote (ETHANF405). The gyro gets its own LDO so logic noise stays off its rail, and a TPS5450 buck makes 5 V straight from the pack. Solder jumpers split the power tree, so I could bring the board up one stage at a time.

ATmega328PB Door Lock Hardware Prototype

Class project · Microcontrollers

Dual-Factor Hardware Security System

A door lock that asks for two things: a 4-digit code on a keypad, then a password over UART. Bare-metal C on an ATmega328PB, with Timer1 PWM driving the servo.

Basys3 FPGA Production Board

Class capstone · Digital design

FPGA Hierarchical ALU & 7‑Segment Display Controller

A 0 to 1000 up/down counter in VHDL on a Basys3. The debouncer, counter, BCD converter and 7‑segment driver each got their own testbench before I wired them together. The whole thing fits in 117 of the Artix-7's 20,800 slices.

Experience

  1. Work · May 2026 to now

    Engineering co-op, now project engineer (part-time)

    Gaylor Electric · Sellersburg, IN

    I started as an engineering co-op on active electrical construction jobs and stayed on part-time as a project engineer. The work is proposal budgets, material procurement and jobsite safety tracking.

    • Started a safety and performance token program that tracks and rewards jobsite safety
    • Built internal automation tools in Microsoft Copilot Studio

  2. Work · Jan 2026 to May 2026

    Student worker, electrical bench tech

    Speed Center for Innovation · University of Louisville

    I helped students debug their embedded projects and bring up their PCBs, kept the test equipment running, and helped people pick parts.

  3. Leadership · Feb 2025 to Aug 2026

    Executive officer

    IEEE Student Chapter · University of Louisville

    Ran the chapter's PCB assembly lab for a group of 15+ students, organized hardware design workshops, and held everyone's soldering to IPC standards.

  4. Leadership · Jan 2025 to now

    Peer mentor

    Engineering Living-Learning Community · University of Louisville

    Mentor to 40 first-year engineering students in the residential program. I also planned two community events, each with about 20 people.

  5. Internship · Aug 2022 to May 2023

    Industrial engineering intern

    Nifco Americas · Shelbyville, KY

    My first engineering job, at a Tier 1 automotive supplier. I learned the design process from the engineers there.

    • Modeled parts in SolidWorks for machine conversions and conveyor upgrades
    • Kept the hardware engineering database current across several plants
    • Updated specs and drawings for global suppliers
    • Saw injection molding and 5S lean practices up close

Build log

A running diary of the flight controller build, mistakes included. Status: airframe built, flips on liftoff.

  1. The flash chip was fine the whole timeThe quad flips as soon as it lifts off, so I finally went back to the blackbox flash. Two days of blaming the chip and one night of thinking I'd killed the board, and it ended up being a missing line in Betaflight.
  2. One motor at full throttle, and a dead flash chipPack and USB live at the same time, throttle up, and the motor just ran. The blackbox flash, on the other hand, is dead.
  3. Bring-up, and a day lost to the ADCStaged bring-up through the solder jumpers, one rail at a time. Everything passed except the two ADC channels I needed most.
