Open-Source Laser Shooting Simulator

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.
