For this project, I designed a FULLY-3D Printed contra-rotating propeller system. The goal of this project was to test the limts of PETG filament and test how it would behave in high RPM applications.
This specific design utilizes a differential with a pass-through shaft to reverse the direction of one of the propellers while the other one is directly connected to a 2400kv drone motor. The propellor blades themselves are also from a regular quadcopter drone.
Created a model Arc Reactor inspired by the Marvel Iron man movies. All of the parts are 3D printed and a few of them are spray painted different colors to closely match the actual Arc Reactor. The lights are powered using a Adafruit Circuit playground express along with a 24 led RGB Neopixel ring. The Rings are made of Copper wire wrapped around and over the base piece to resemble the copper on the actual Arc Reactor
I designed this custom F1 steering system for an RC F1 Car project I am still working on. It features the classic parallel wishbone layout with an L-shaped linkage controlled by a 9g micro servo. The wheels, vertical rods, and springs were salvaged from a Ferrari FXX 2005 RC car.
Using the XIAO ESP32C6 Dev Board from Seeed Studio, a salvaged motor from a servo module, and a spare 3.7v LIPO battery, I converted a simple Hot Wheels model of an ND Mazda Miata (modified) into a basic RC Car that could be controlled using a web server with basic inputs. I initially tested the system using a simple Arduino nano controller since it was already pre-configured to be run with Arduino IDE. The Steering linkages are not the most stable as they are basically microscopic however they still work as intended.
I used some standard addressable RGB strips connected to a Seed Studio XIAO esp32c3 microcontroller and wired it to the 12v socket using a voltage buck converter on my 2022 Miata to be used as a 3rd taillight for nighttime driving, as well as a colorful display for car shows and more.
