Introduction: HOW TO MAKE ADVANCED LASER PROJECTOR

Picture of HOW TO MAKE ADVANCED LASER PROJECTOR

Hello there!

Today we make for you very nice and awesome laser projector from lasers, motors and mirrors. If you like our video, please subscribe! :)

For making this awesome projector you need:

  • Cardboard
  • 3 Lasers
  • 5 Electric Motors 6V
  • 5 Mirrors
  • Ice Cream Sticks
  • Wires
  • Contacts
  • Hot Glue
  • Batteries
  • Transistors
  • Variable Resistors
  • Voltage Regulators
  • Power Slot
  • Buttons
  • Power Supply 6V

First of all look the video instruction ->

Let's go!

Step 1: Mirrors

Make a platform of ice cream sticks.

Install the electric motor and glue the mirror.

Step 2: Speed Regulator

It is necessary to have a variable resistor of 0-4.7 kΩ and a transistor.

Solder the transistor to the resistor as in the picture. To the middle leg we connect plus from a food. To the left leg, we attach a plus to the electric motor.

Step 3: Lasers

We connect the lasers to the external power supply and the switch.

In this way, the laser can be turned on from the outside.

Step 4: Install

Install mirrors and lasers on the platform.

I made such a scheme. But you can set it on your own.

Step 5: Power Supply

Connect power.

Plus goes to the middle leg of the resistor. We take the minus from the electric motors.

Step 6: Assemble the Box

I cut out my hole for each mirror regulator.

Also the switch of each laser.

Step 7: Enjoy

I made a similar device a couple years ago using an arduino and a 4 channel motor control shield. The arduino generated random motor speeds to generate random patterns. If you time the switching to music, it makes a really cool show.
