Hashmi.
Mechanical Engineering and Computer Science student at Binghamton University. I build things that move: aerodynamic wings, autonomous vehicles, electric go-karts. Then I document every step, so somebody else can build them too.
Right now that means aerodynamics on the Binghamton Motorsports SAE team, running the 3D printers at the MakerLab, and turning this site into a proper open engineering resource rather than a portfolio.
Before that: flipping and rebuilding cars, antweight combat robotics, and quantitative trading competitions.
What I've been doing.
Four things running at once, which is roughly the normal state of affairs. The dates are start dates; everything here is still going.
Running the lab's FDM machines for student-submitted parts, and keeping print quality, dimensional accuracy and material use where they should be.
- Maintain and troubleshoot the printers through routine calibration and preventative work.
- Use laser scanning and digital fabrication for reverse engineering and prototyping.
- Manage the print queue, tracking status and prioritising for fast turnaround.
- Help students get their CAD ready to print, and suggest changes that make parts stronger.
- Develop custom airfoils in Fusion 360 and Ansys Fluent CFD.
- Build meshes and calculate drag and lift coefficients across conditions, iterating on the results.
- Produce 3D-printed female moulds and lay up parts in 3K and 12K carbon, vacuum bagged and cured.
- Contribute weekly to design and fabrication on an electric go-kart platform.
- Merge individual parts into a master assembly in Fusion 360 and validate fit.
- Build fabrication capability through MIG welding, notching, surface prep and printed fit-check mockups.
Design, build and compete with antweight-class one-pound combat robots in a team of three.
- Design regulation-compliant parts in Fusion 360 and improve structural integrity.
- Print, machine and assemble successive iterations, validating tolerances and function each cycle.
- Solder and integrate drive motors, radio systems, batteries and weapon motors to combat standards.
- Refine designs against stress and performance data while staying inside competition rules.
An end-to-end custom hardware brand, covering demand generation, build operations and getting the thing to the customer.
- Lead build scoping, component planning and quality control.
- Coordinate timelines and deliverables across a small team.
- Track sales, inventory and margins.
What I know how to use.
Tools I have actually built something with, rather than everything I have ever opened.
