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
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 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.
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.
