GlowBlaster Uses 405 Nm Laser To Make Its Mark

June 4, 2024 by 25 Comments

Ever wish you could do a little target shooting in a galaxy far, far away? Well then you’re in luck, as the Star Wars inspired GlowBlaster designed by [Louis Abbott] can help you realize those dreams with a real-life laser pistol — albeit a much weaker one than you’d want to carry into a Mos Eisley cantina.

Inside the 3D printed frame of the GlowBlaster is a 5 mW 405 nm module, an Arduino Nano, a speaker, a vibration motor, and a 9 V battery. When you pull the trigger, it pushes down on a 12 mm tactile button which causes the Arduino to fire the laser and sprinkle in a bit of theatrics by way of the speaker and vibration motor. There’s also a second button on the side of the blaster that lets you pick between firing modes.

Open-Source Laser Shooting Simulator

November 20, 2014 by 43 Comments

Looking to practice your marksmanship skills at home? Check out the homeLESS (Home LasEr Shooting Simulator), an open-source tool for marksmanship practice. [Laabicz] developed this system as a cheaper alternative to commercial laser shooting simulators, which are just as simple but very expensive.

[Laabicz]’s simulator primarily uses modified airsoft pistols that are fitted with batteries (installed in the magazine) and a laser in the chamber. Any gun can be used with the system as long as you can figure out how to attach a laser and trigger switch. To power the laser, a small capacitor is charged from batteries when the trigger switch is off. Once the trigger is pressed, the capacitor discharges through the laser and makes a short pulse of light.

The simulator is written in Processing and requires a projector and a webcam. The Processing sketch projects configurable moving targets on a screen or wall, and the webcam detects when a laser is triggered over any of the targets. The software supports multiple target types (including moving targets) and is quite configurable. Check out the video after the break to see the system in use.
