I'm an engineering student with a passion for making and design. The MakerSpace has been a great opportunity for me to work on projects ranging from musical electronics, to robotics, to medical devices. I love the fact that the space is open to people from all departments and majors. I've definitely learned more from the unique perspectives of our users than I ever could have on my own. Right now, I'm working on writing a library for generating different geometric patterns on the laser cutter, improving my team's biopsy punch design, outfitting more of our marching band with sound reactive lights, and a visually driven drum synthesizer.

The automated biopsy punch solves the problem of the currently time consuming and inconsistent process of taking a punch biopsy for the diagnosis of melanoma and carcinoma. The CMDX Biopsy Team (Sydney Chestler, Ryan Fishel, Perri Levine, and Ben Lewson) have been developing this technology since 2014, for both the Tulane University Novel Technology Challenge and their respective Senior Team Design projects.

Holy expletive, we won! I'm incredibly grateful for the opportunity to have worked with such creative and talented engineers. I truly can't wait to work with these guys in the future.

The Sunflower is a modular Solar Electric Propulsion (SEP) Tug system designed to transfer cargo from Low Earth Orbit (LEO) to Lunar Distant Retrograde Orbit (LDRO) economically and efficiently.

  • Deployment
  • Initial Unfolding
  • Unfolded half-array
  • Fully Assembled in LEO
    • Automated Biopsy Punch

    The automated biopsy punch solves the problem of the currently time consuming and inconsistent process of taking a punch biopsy for the diagnosis of melanoma and carcinoma. The CMDX Biopsy Team (Sydney Chestler, Ryan Fishel, Perri Levine, and Ben Lewson) have been developing this technology since 2014, for both the Tulane University Novel Technology Challenge and their respective Senior Team Design projects.

    • Bearing fit on DLP print (Looks good!)
    • DLP printed helical drive mechanism
    • Helix drive mechanism overview
    • 4 Axis CAM Toolpath for helical drive
    • Deflection Analysis of prototype case under typical load
    • Gear motor mounted in 3D printed casing
    • Needle bearing press-fit into housing
    • Test blade in manually driven rotating housing

    • Cross Section of full CAD model
    • Laser Engraver
    Videos: Motion Test Sample File Engraving Test

    This is what happens when information about the GRBL embedded CNC controller, the discovery that reasonably high-wattage laser diodes are available cheaply on Amazon, and a few hundred dollars all fell into my lap at the same time. It was a really interesting project that taught me quite a bit about CNC control workflows, powering laser diodes, and the joys of 80-20 aluminum extrusion.

    • The first successful engraving-a simple geometric pattern in wood
    • The X-axis carriage of the engraver-Driven by toothed belt and pulley
    • All the components of the engraver-Motion is functional at this point
    • The X and Y axis with motors mounted-Wires have yet to be sleeved and cut to length
    • Stepper driver board with 1 driver installed
    • Sound Reactive Drum Lights

    As a proud member of the Tulane University Marching Band from 2014 to 2016, I was incredibly excited for the chance to add sound reactive lighting to our drumline to make our Mardi Gras parades a little more exciting and possibly disorientating.

    • Lighting array mid performance. The battery is holding up!
    • Semi-complete boards for version 2.
    • Infinity Table

    For when you need a side table for your dorm room, but you have a pathological obsession with blinking lights and haven't heard of addressable LED strips yet.

    • All of the light segments powered on for the first time
    • All segments placed in frame for fit check and reflection test. Looks good!

    Maker Skills:

    • 3D Printing
    • Laser Cutter
    • CNC Mill
    • Analog Electronics
    • Microcontrollers
    • Machining
    • Design for Manufacture
