The year end project for second year MECH was to build a hovercraft within a team and compete through various circuits. Constraints were placed on the type and number of batteries we were allowed to use. In addition, we only had two weeks to prepare. My team consisted of six members and we placed 3rd out of 20 teams.
Skills used:
programmed a ATtiny85 DIP to receive data from an RC receiver and variably control LEDs based on throttle input
conducted experiments to determine RPM of motor paired with different propellers
soldered circuit for microcontroller on a perfboard to reduce volume and mass
3D-printed parts for prototyping different skirt designs
used multimeter to determine the relationship between voltage and motor RPM
Differential Steering (Concept) Circuit
Differential Steering (Concept) Logic
Circuit for LEDs
Second year Mechanical Engineering project to gain experience with different tools.
Skills used:
press brake to bend sheet metal
drill press to deburr holes and drill various holes
lathe to machine the cylindrical block holding coil
mill to machine the block holding PCB
hand tools such as files, screw drivers, saws
tapped holes for screws
soldered components to PCB
followed engineering drawings and machined parts within tolerances
Skills used:
C programming for Arduino to activate servo motor when ultrasonic sensor returns a set distance
prototyping
followed design process and performed iterations to improve design
analytically conducted risk assessments
As part of first year course APSC101, we were tasked to create a claw retrieval system to pickup various objects. The claw had to be made from cardboard and other readily available materials such as pencils, paper clips, popsicle sticks, etc. Below are pictures of my final design:
