AMPTR 3D Printer
I built a 3D Printer for my 3D Printing
course. Wire management was a
challenge for the moving components.
My group and I decided to put the
control panel at an angle in order to
make it easily readable from a
standing position. The entire system
was controlled by an Arduino with
open source software, Repetier.
Mr. Roboto, the Music Teacher
This was a robot that could play
a children’s piano based on a
preset song. Paint chips were
put on each key so that the robot
would look for a specific color
for each note. It was controlled
by an Arduino and sensed color
via a Parallax ColorPal.
Balloon Air Demo
At Enventys, I led the interns in
making a demonstration of how
a system of wood sealing is
noticeably better than the
standard methods. This was the
air test, similar to wind against a
building, with the intent to be
presented at trade shows.

e-NABLE Hand Test Rig
I originally worked on this project as an
Independent Study in association with e-NABLE
Lab at RIT. The apparatus compared input force
versus output force in order to quantify the
efficiency of the 3D printed prosthetic hands
developed by e-NABLE. The data would be used
by developers to compare designs and methods.
e-NABLE Hand Test Rig
I continued working with a team of
engineers for our Multidisciplinary
Senior Design project to further my
work and develop the next version of
the testing device. It was able to test
more e-NABLE hand models and sizes,
compare wrist angle to force output,
and transfer the data live via Arduino
to Microsoft Excel.
