NEW GUIDE: John Park’s Overwatch Prop Gun Lucio’s Blaster pt.1 @adafruit @johnedgarpark

luciothumbnail_853

Build a prop blaster from the hit video game Overwatch! Check out the behind-the-scenes process as I make Lucio’s gun from scratch. This guide is part 1 of a multi-part series, in which I design and test each light, music, and sound effect function.

Learn how to build your own Overwatch prop blaster with this multi-part guide! This 3D printed prop gun will include lights, sound effects, and background music, all played through a 20 watt amp and four speakers.

In part 1 we’ll design the electronic functions and overall circuit design, and then build the individual functions as working prototypes.

I like to test out each subsystem in isolation before deciding how to combine and optimize. Clockwise from the left: NeoPixels, background music, sound effects trigger.

This is my rough schematic drawing of the parts and functions.

Keeping things organized with parts bins (labeled by my very helpful daughter).

A small-scale 3D printing test of the gun. I’ll detail this process in a later guide as I remodel this as multiple parts that fit all of the electronics.


Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
