We will be making a laser show that involves mirrors, speakers, and lasers!
Step 1: Gather Materials!
For this project you will need:
- small mirrors
- a <5mW laser (for the best effect)
- a base ( a wood, metal or plastic sheet to mount all the items
- a small computer speaker set
- a music source (phone, mp3 player)
- a screwdriver
- double-sided tape
- glue gun
- metal clip ( to hold laser)
optional: small metal clips ( to mount extra mirrors)
Step 2: Ready the Speakers
establish a clean base, make sure there is nothing sticking out of the piece of plastic, metal or wood. Get the computer speaker set and if there is any mesh or covers on it, using a screw driver take out the screws holding the cover of the two speakers. You will then see the inside of the speakers, it will look sort of like the outside of a sub woofer. Test out the speakers and see if they still work. As the music plays touch the circular speaker and see if they vibrate. If they do, we are ready to go!
Step 3: Mount the Mirrors
Acquire the small mirrors. Using a small piece of double sided tape, take a small square mirror and mount it on the cone, slightly under the direct center. Repeat this process for the second speaker as well. Make sure the mirrors are properly placed.
Step 4: Set Up the Project
Now take the base and mount the two speakers in the top left hand corner of the base using a glue gun or tape. now using one or two lasers. mount the lasers. You can mount the laser using the metal clips, place the laser in the clip and you can even let the laser stay on by putting the clip over the on button.
Step 5: Final Touches
Now turn on the lasers and try to position them so they directly hit the mirror on the speaker and bounce off to hit a wall. You will want to move the clip or the speakers so they will be positioned exactly to hit the tiny mirror.
Now hook up the speakers to the music source and play some really cool music that has a lot of different sounds (I recommend dubstep music). Keeping the lasers on, play the music and watch the really cool figures the laser make on the wall!
Step 7: Additional Step
If you want to make your project even cooler. you can also add extra mirrors on your base for the lasers to bounce off of before reaching the mirror on the speaker. It looks really cool after you do this!
Step 8: Additional Tips
For the best effects you should use a fog machine so you will clearly be able to see the laser beam!
