Introduction: HOW TO MAKE ADVANCED LASER PROJECTOR

About: Welcome to the Delta Hack Channel! Here you will find interesting and awesome life hacks and tricks! Subscribe! ;)

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.

    Great Instructable. Could you please add circuit diagram.
