The goal of this project was simple: I’m planning to attend an upcoming Comic Con event in Gurugram, and I wanted to create a quick, wearable gauntlet-style prop. I won’t be wearing the full suit—just the gauntlet—and the Mega Buster is something I’ve always wanted to build. I used to play Mega Man X on my Windows 98 PC years ago. The game was brutally hard, but it was a big part of my childhood, and I wanted to bring a piece of that nostalgia into the real world. That’s why I chose the Mega Buster.
Here's how it works: inside the Mega Buster, there’s a push button used to trigger the firing sequence. When the button is pressed and held, the blaster begins charging and plays a charging sound effect. Once the button is released, the front red LED flickers, simulating the firing of a plasma beam.
The plasma beam remains active for the duration of the button press; the longer the button is held, the longer the beam fires. After firing, the effect slowly fades out and turns off.
On the side of the blaster, there’s a six-bar power indicator that acts like an ammo meter. Each time the plasma beam is fired, one bar is depleted. Once all six bars are empty, the side indicator, front blaster LED, and speaker all blink red for 10 seconds, indicating a cooldown period. After the cooldown finishes, the device resets and power is fully restored.
This article covers the complete build process of the project from design to electronics and final assembly.
Let’s get started.
MEGAMAN
For anyone unfamiliar, Mega Man, also known as Rockman in Japan, is a classic action-platformer franchise created by Capcom. The series follows a humanoid robot named Mega Man, originally called Rock, who battles rogue robots using special weapons acquired from defeated enemies. One of the most iconic elements of the franchise is the Mega Buster, an arm-mounted energy cannon capable of firing charged energy shots.
Since its debut in the late 1980s, the Mega Man franchise has become known for its tight controls, memorable music, and challenging gameplay, earning a dedicated fan base across multiple generations.
My introduction to the Mega Man universe came through Mega Man X. Unlike the original Mega Man series, Mega Man X does not focus on the original Mega Man (Rock). Instead, the main protagonist is X, a new-generation robot created by Dr. Light. X is designed with the ability to think, feel, and make moral decisions, which gives the Mega Man X series a darker and more mature tone compared to the classic games.
Another major difference introduced in the Mega Man X series is Zero. Zero is a powerful ally and sometimes rival who uses a beam saber instead of an arm cannon. While early Mega Man X games focus mainly on X, later titles allow players to switch between X and Zero, each offering distinct fighting styles, abilities, and upgrades.
Now that the basics are covered, let’s move on to the project.

DESIGN
We start the 3D model-making process by first getting a reference image of the Rock Buster from the internet. We import the image into Fusion 360 through the canvas option, then use the calibration function to set the length of the whole gauntlet to 330 mm.
The whole gauntlet is symmetrical, so we can easily make this using the revolve function. To do this, we trace the outline of the gauntlet and then use the revolve function to make a solid gauntlet body.
For the engineering process, we first divide the body into three main sections. The front part is the blaster section, the middle body is a hollow part in which we add the handle grip that is used to hold the whole gauntlet, and inside this section we also add the main control circuit. The third part is the back section, which contains a cushion that supports our arm.
The middle body, or main body, on the left side contains a replica of the yellow power bar. This part is basically a slot...
