im working on a robot project for a friend.he wants me to install the laser behind a hole in the robots face.the robots head moves and it makes sound using a remote control.its 8ft tall. my question is he wants to use this at his backyard parties. how can i use this laser and keep it safe from any bouncing beams of if it shoots into a neighbors yard? can i use a filter or flasher so it turns on and off every second? i dont want anyone looking direct into the beam and thought of diffusing it somehow so its safe.any ideas would be great.thank you.
