Portrait of Sean Conway

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.

Coil Gun

Demo video

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

Stop-motion video

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
