Maker mods his NERF blaster into a fully-functional Halo 5 MA5D


A DIY weapon for Humans vs. Zombies — with an ammo counter, scope and all!


Jeremy Chang is a big fan of Humans vs. Zombies (HvZ), a live-action game where players try to survive a post-apocalyptic world using soft toys like socks and foam dart guns. Well, in this case, the Maker decided to do something a little different and add another layer of roleplaying to his HvZ experience by modding his NERF blaster to resemble a Halo MA5D assault rifle.

This device boasts a number of impressive features, which range from a digital ammo counter to a functional scope. Based on the fictional United Nations Space Command weapon, the 3D-printed replica certainly looks ready to obliterate zombies.

In order to get the iconic shape of the MA5D, Chang used some 3D-printed part to upgrade his blaster. On the inside, Chang employed an Arduino Nano (ATmega328) to detect trigger pulls, a few reed switches in the chamber to determine the current ammo count and an Adafruit 128×64 OLED lit with a NeoPixel LED. (The color on the screen change as the percentage of ammunition goes to zero.) The display even has a functional mission timer and will reveal if the clip is not fully closed. Aside from all that, a 5V scope adds a nice finishing touch to the MA5D prop.
