Couple years back, I had my attempt (I like to call it Poor Man’s attempt btw) at making a simple laser projector. Well, I’ve seen better ones including this lego laser projector that uses diffraction grating to literally shoot laser beams into abysmal pit of awesomeness!

Wow, check out this green/red laser projector which can do animations.
This is one of my experimental Dance/Trance songs from 2000. I build laser systems for fun so I have put together pictures and clips from assembly to a full working system to go with the song. I know the song gets really annoying after awhile sorry. Iv’e been getting a lot of email asking how the projector works and what parts are i

Remember my Green Laser Projectr DIY? Well, here’s a similar DIY project except it uses a speaker to send vibrating pulses to the end-results beams instead of a motor.
So how does one go about making one of these things? Well, I made every effort to make con
Here’s a really cool DIY showing you how to build a hard disk laser scanner made from bunch of old hard disks.
My latest tinkery hardware and embedded systems project is a homebrew laser scanner. You know, the kind you see at planetariums- sweep a laser beam around on the wall really fast, and draw vector graphics. Commercial laser scanners have been around for decades now, but buying a complete system is still really pricy, even on
Remember I made a simple homemade DIY green projector? Well you can buy one at Brando gadgets for about $80.

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 spe

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 las

Remember I did a review on a 125mW Viper green laser last year?
Well Frank from DragonLasers sent me a Spartan GW 250mW green laser so I can show you guys how cool it is. The beam is much bigger this time and as you can see in the video, it’s WAY more powerful. Everytime my fr
Check out this cool laser projector using AVR. WOw.
Motor spins drum with 16 mirrors around at about 20-30 rev/second. The mirrors are tilted differently, so that they draw one line each on the screen. Rotation time is measured by the reading fork and divided by 16*32=512. This is the pixel clock. When the reading fork senses that the wire attached to the mirror drum passes, a new frame starts, and the pixel clock starts. For each pixel, the las
