Hardware & Embedded Systems Engineer
Sean Conway
Howdy! I'm Sean, a hardware and embedded systems engineer with a passion for building things that move, sense, and communicate. I enjoy taking ideas from concept to prototype to production, and I love learning new technologies along the way.
Projects
RefRemote
Developed by iteration — from a perfboard prototype through three PCB revisions.
[Description: what this first prototype was built to prove out, key components/architecture, and what you learned that shaped Rev 1.]
[Description: first PCB revision — what moved off perfboard, design decisions, and issues found in this rev.]
[Description: adding the enclosure — mechanical constraints, fit/finish decisions, connector placement, and any changes carried back into the PCB.]
[Description: latest/current revision — what's final about this design, remaining known issues, next steps.]
Capstone
[One-line summary of the capstone project.]
[Description: what the capstone project was, your role, the problem it solved, technologies used, and outcomes/results.]
SmartTin
[One-line summary of the SmartTin project.]
[Description: what SmartTin is, the problem it solves, key components/ architecture, and outcomes/results.]
FitnessSlot
[One-line summary of the FitnessSlot project.]
[Description: what FitnessSlot is, the problem it solves, key components/ architecture, and outcomes/results.]
Coil Gun
A fun little physics demo project I built in college. The coil gun is a simple electromagnetic projectile launcher that uses a coil to accelerate a ferromagnetic projectile down a barrel. It uses 4 9V batteries to charge a bank of 8 4700uF capacitors, before quickly releasing their energy through a coil to induce a magnetic field that propels the projectile. The gun is operated by a 3 position switch which toggles between idle, chargining, and firing states and feaures an LED indicator which lights up when charging begins and gradually dims as the capacitor bank is charged, going dark when the gun is ready to fire. Credit: This project was inspired by the book "15 Dangetously Mad Projects for the Evil Genius" by Simon Monk.
MMA Stop-Motion
A stop motion demonstration of a number of mixed martial arts techniques. Uses 3D printed Dummy 13 figures to demonstate the biomechanics of various techniques. I used FILM (Frame Interpolation for Large Motion) python library to interpolate frames between the stop-motion frames to create a smoother video accepting the tradeoff of some visual artifacts. Just something I had fun putting together and like to share. Techniques demonstrated: 1. Counter Cross, 2. Osoto Gari (Major Outside Reap), 3. Overhand right single leg entry -> golf swing finish, 4. Lead leg teep -> tomahawk elbow -> left hook, 5. Front Kick, 6. Superman Punch, 7. Roundhouse Head Kick, 8. High-C -> Run the pipe -> lift, 9. Wheel Kick, 10. Taio Toshi (body drop), 11. Flying Knee, 12. Body lock -> Suplex, 13. Tornado Kick
