Fire Fist
Creating a practical effect for an impossible ability.

I got to take my [now wife!] to San Diego Comic Con 2019. She went all-in, and wanted to cosplay as Carol Danvers (aka: Captain Marvel). So I embarked on the challenge of bringing a digital-screen effect to life.
Through prototyping, iteration, and interaction design, I successfully recreated the mesmerizing "fire fist" from Captain Marvel. It was a rewarding experience, diving into the realm of visual effects and captivating cosplay enthusiasts
Power(ful) lessons
The initial challenge was designing and constructing a functional circuit to recreate the "fire fist" effect. This involved sourcing suitable components for generating harmless smoke and properly illuminating it to create a realistic "fire" effect.
During the initial stages, I encountered a challenge when integrating the mini smoke machine into my circuit design. I had overlooked the need for a start-up or inrush current required by the smoke machine, causing it to malfunction.
After extensive research and hours of troubleshooting, I discovered this crucial variable and modified the circuit to provide sufficient current flow, successfully enabling the smoke machine motor to initialize and operate seamlessly.
This project introduced me to the intricacies of powering a physical system : how to read component specs, calculate power requirements, and troubleshoot shorts or issues that arose. It enhanced my problem-solving skills and ability to adapt to new technologies.
(Super) Human Factors
The challenge of creating a functional circuit for the "fire fist" effect extended to addressing user concerns about safety. Having a circuit that was always "on" made the user nervous. So we worked together to find a solution that would provide a strong sense of control and trust.
Through discussions and experiments, we came to a solution: dual power controls. One to break the circuit at the power supply and another to activate the "fire fist" effect. This iterative approach ensured that the user felt confident and in control of the device.
Final thoughts
For me, this experience reinforced the significance of user trust and control in interaction design. It showcased the value of empathizing with user concerns and iteratively refining the product to enhance safety and user experience. By designing for trust, I created a compelling and user-centric product that resonated with cosplay enthusiasts, while prioritizing their peace of mind.
