DIY Laser Tag Project Does It In Style

October 26, 2024 by Donald Papp 21 Comments

This DIY lasertag project designed by [Nii], which he brought to Tokyo Maker Faire back in September, is a treasure trove. It’s all in Japanese and you’ll need to visit X (formerly Twitter) to see it, but the images do a fine job of getting the essentials across and your favorite translator tool will do a fair job of the rest.

There’s a whole lot to admire in this project. The swing-out transparent OLED display is super slick, the electronics are housed on a single PCB, the back half of the grip is in fact a portable USB power bank that slots directly in to provide power, and there’s a really smart use of a short RGB LED strip for effects.

The optical elements show some inspired design, as well. An infrared LED points forward, and with the help of a lens, focuses the beam tightly enough to make aiming meaningful. For detecting hits, the top of the pistol conceals a custom-made reflector that directs any IR downward into a receiver, making it omnidirectional in terms of hit sensing but only needing a single sensor.

Want to know more? Check out [Nii]’s earlier prototypes on his website. It’s clear this has been in the works for a while, so if you like seeing how a project develops, you’re in for a treat.

As for the choice of transparent OLED displays? They are certainly cool, and we remember how wild it looks to have several stacked together.

DIY Laser Tag System Comes With All The Bells And Whistles

January 7, 2021 by Danie Conradie 29 Comments

While VR is becoming really immersive, it still can’t compete with a game of good old laser tag to get the blood pumping and spending quality time with friends. [Xasin] has been working on a DIY laser tag system for a while now, and it has grown to include an impressive array of features and customizability.

Named LZRTag, the project started back in 2018 with simple ATmega328 based prototypes on breadboards. It has since evolved to a fully-featured system with ESP32s in the 3D printed pistol communicating with a Raspberry Pi/Linux game server over MQTT. Each pistol also features an accelerometer, I2S audio amp and speaker for game sounds, and WS2812 RGP LEDs for light effects. IR Lasers are used as emitters to target wearable IR receivers with more RGB LEDs wired to the pistol.

A Ruby server on a Linux machine takes care of all the communications, game management, shot validation, and scoring. It can handle up to 255 players and is designed to be extremely customizable for game modes, weapons classes, or any other feature you would like to have. [Xasin] has also created IR beacons to add even more possibilities, such as capture the flag, safe zones, and revive zones.

We really like the flexibility of the system, and it would make an awesome group project for a hackerspace. You could also add a shock module to motivate players a bit more to avoid getting shot.

Custom Laser Tag Rifle Packs A Sonic Punch

February 6, 2020 by Lewin Day 33 Comments

Laser tag is rarely (if ever) referred to as “The Sport of Kings”, but is a fun pastime nonetheless. While some are content to play with off-the-shelf toys, others prefer to make their own gear to suit their needs. [Heine Nielsen] is just one such builder, creating a fully-featured laser rifle loaded with features.

As far as hardware goes, [Heine]’s laser rifle is packed to the gills. There are two ESP32s running the show, along with a meaty 6S lithium battery to provide plenty of juice for long combat sessions. A 40W audio amp is hooked up to a speaker mounted in a faux-grenade launcher, aping the design of the M203 – and is able to deliver ear-splitting sound for that realistic touch.

Knowing the popularity of modern FPS games, [Heine] cribbed a lot from titles like PUBG and CS:GO. Grabbing sound effects from various weapons was just one step, with the ultimate goal being to replicate advanced game modes from these games. To help keep the player aware of the game state, there’s even a HUD on the gun, thanks to a 2.8″ TFT screen tucked into the scope.

It’s a serious build for playing serious laser tag, and we’d love to head out to the field for a match with gear like this. We’ve seen other hyper-realistic builds before too, like this one that uses actual blanks. Video after the break.

Firing Blanks With Laser Tag

June 2, 2014 by Brian Benchoff 37 Comments

glock Last year, [Tony] was asked to develop a lasertag system with ultimate realism. This meant a system that used a blank firing replica gun, and a system to detect blank rounds being fired. Very cool, and the way he went about it includes some interesting electronics.

Because the system requires a blank to be fired before shooting a laser at a target, the entire system must be able to detect a blank being fired. [Tony]’s first attempt used a piezo sensor to detect the shock from being fired. This system had a lot of noise and was ditched for a much better solution: a magnet mounted to the slide, and a hall effect sensor mounted to a 3D printed frame that turns this replica into a carbine.

A little bit of tweaking in software was required to inhibit the laser when the operator cocks the gun, but it looks – and sounds – really good. It’s also very, very realistic: the only way to shoot an opponent is to physically reload. Video below.

Hacking Laser Tag And Building Custom Guns

August 8, 2012 by Brian Benchoff 12 Comments

As [Brad] over at the LVL1 hackerspace watched his friend build a Laser tag/tazer mashup for Makerfaire Detroit 2012, he noticed these new laser tag guns were really cool. These Light Strike guns have an impressive array of electronics for a $30 toy, but there was still much to be desired. [Brad] decided to reverse engineer these guns and work on a drop-in replacement for the game’s electronics so people like his friend can hurt themselves more easily.

The Wowwee Light Strike guns operate with IR LEDs, so the obvious solution for decoding the laser tag protocol would be the Arduino IR remote library. [Brad] had a bit of trouble getting his Teensy to read the IR data correctly, but after connecting everything up to a logic analyzer he had the data format figured out.

Now [Brad] has the Light Strike data format figured out and is theoretically able to make his own guns that are compatible with the off-the-shelf laser tag system. It’s also possible for [Brad] to extend the capabilities of this laser tag system by using the ‘health’ function to create a medi gun, or build a gun with a larger magazine for a laser tag mini gun.

If you’d like to build your own version of laser tag compatible with the Wowwee Light Strike, you can grab all the code on [Brad]’s git.

Robot Laser Tag

[Shay] and his friend built some battling robots for a school project. Instead of destroying each other’s robots with saws or torches, they are playing laser tag. Each robot sports an eeePC, a laser pointer on a movable arm, and some photoresistors. The goal is to get your laser to hit the other robot’s photoresistor to lower its health towards a kill. A server keeps track of the bout, monitoring shot fired because you won’t find unlimited ammo in this game. As for piloting the rig, the netbook webcam is streamed to a control station with an Xbox 360 controller for motion, aiming, and firing. Check it out after the break.

Warthog Laser Tag

April 12, 2010 by Mike Szczys 11 Comments

The Warthog from Halo is one of the most beloved video game vehicles. [Tim Higgins] brings the fun to life with his laser tag Warthog game. It uses Barbie Power Wheels toys as a base and adds laser tag weaponry. Xbox 360 controllers are used but just like in Halo, you can’t control the gun and the vehicle at the same time. We’ve encountered [Tim’s] love for water-based amusement before and this did originally start out with a water cannon powered by a wind-shield washer reservoir.

Take a look at the videos after the break as well as his recent post for information about the hardware. His choices for controller circuitry are way overpowered, sourcing an Eee PC to do the heavy lifting. This is because the choices he made were for easy development and not economy of components. A PC has no problem connecting to Xbox 360 controllers, and the modular control boards mean no complicated circuit design or arduous soldering were necessary. In the end, this looks like a ton of fun and we give him bonus points for repainting the pretty pink plastic that comes standard with these models of children’s toys.
