Remember I made a simple homemade DIY green projector?  Well you can buy one at Brando gadgets for about $80.

How to Make a Green Laser Projector

Since I have been playing with green lasers for about a year, I never saw any good use for them except to point them to the sky or buildings.

Since the green laser has a lot of power, especially the one DragonLasers sent me recently, I decided it was time to make a simple green laser projector without me spending days to build one.

This simpler green laser projector was made so I could use it for my next party and I always wanted to make this. Although this laser projector only does one animation, 2 whirpools, I planned to improve upon after making this very basic version.

When the motor is stopped, it also displays a bunch of green laser stars like this:

Step 1

First, you will need a green laser. I recommend anything 125mW and above.

For this DIY, Frank from DragonLasers.com sponsored me a Spartan 250mW green laser. (Thanks Frank!)

You also need a diffractive glass that will distribute the green laser beams. I was lucky that the Spartan comes with it. You could probably use those cheap diffractive glasses from 3D glasses too.

Second, you will need a plastic epoxy. (In the video, I say you need two but you just really need the plastic epoxy as it works really good for everything.)

Third, you need bunch of pipes. I went to home depot and got bunch of cheap galvanized pipes for about $10 total.

Step 2

You need to drill a hole in the center of the diffractive glass, then epoxy it to the motor. Now, I accidently broke the glass and had to epoxy everything. Just make sure to use a real thin drill and go slow so you don’t make the same mistakes that I did.

Then, also epoxy the bottom end of the motor to the 90 degree pipe arm. (Make sure to solder on 2 wires to the motor!)

(Sorry, I forgot to take pictures while doing that…)

Step 3

Build your green laser projector using the pipes and pipe parts sorta like below.

Put all the wires through the pipes so it comes out the other end. (Sorry again, I forgot to take pictures of this step…) Then assemble everything. You can fit the green laser through the T-pipe piece. (For the T-pipe piece, I used a bigger size then used electrical tape around the pipes to stabilize it.)

Step 4

Now you have two wires coming out the other side of pipe. Simply connect that to a 1.5V battery OR you can use a DC adaptor.

Step 5

Once you get the motor running, simply align your green laser and there you go, a simple green laser projector.

You should get nice set of two whirpools of green laser beams.

Now, you could probably add another axis and another motor to get even better animated effects.

I plan to add a microcontroller like CUBLOC or Basic Stamp in the future so stay tuned and subscribe to Zedomax.com.

This DIY was made to experiment with the green laser, so don’t shoot me if it’s not super high tech. It’s supposed to be simple enough so any regular joe can make one. But I promise next time it will be more high tech…

One of our long-time readers and a winner of a free Green Laser, Brian Gaut from Schwippy, has made a new website explaining how to make the Emergency Party Button and transform your livingroom into an automated “Jame Bond style” party room.

As seen in the video, this is a great way to transform your livingroom into a party dance club.

Once Brian presses on the emergency party button, the curtain closes automatically, light dim out, then all the party lights, music, laser, steam, and strobe lights start coming out.

Really neat, great job Brian for finally documenting your party invention!

Basically, it is exactly what it sounds like; a button that instantly launches a party. When pressed, the blinds to my apartment close, the kitchen, hallway, dining room, and living room lights dim, the stereo starts blasting Haddaway - What Is Love, black lights turn on, laser lights start moving to the music, a strobe light goes on, and the fog machine starts up.

With another press of the button, the party is gone as easily as it started.

It may not be the most hi-tech thing in the world, but people sure as hell love it when they come over.

The parts are pretty discrete so if you live with your parents, you might even use this method to “hide” your weekend parties while your parents are gone.

Yey, Laser Christmas tree!  It’d be great if you had a Christmas Rave in your house.
