Halo | Firebender

Punch-activated flamethrower.

Inspired by Avatar: The Last Airbender.

Publicity stunt for the startup Halo where I worked Summer 2025

*Disclaimer: this was sold as a consumer device in a limited run.

Features

Industrial Design

The 3D-printed PETG parts were designed mainly by in Fusion 360. Inspired by the Portal Gun aesthetic from Valve.

Render made by me in Light Tracer.

While similar to prior attempts by people to make something similar (eg. Allen Pan), this version was intended to have a limited consumer run and was therefore designed more user-friendly and safe.

This was done through multiple safety mechanisms including a pressure sensors, redundant solenoids, and butane release valves.

Is it a flamethrower?

Technically, yes it's a punch-activated flamethrower aiming to give one a sense of firebending.

Legally though, because the flames are less than 10ft, it's an arm-mounted extendable camping stove..

Electrical System

The system ran off of a XIAO NRF52840 BLE Sense, Relays, Arc Lighter, Solenoids, and Butane.

Shoutout also to Cael, my fellow intern and collaborator in this project.
