Drawing with lasers is really fun especially if you set your digital camera in stealth, long exposure mode.

How to use a laser pointer to draw, to write and to record it? I think it is a very interesting thing. With the help of a camera with the function which could set longer exposure time,you could easily record what you draw and write with the laser pointers.The laser pointers include 405 nm blu-ray laser pointer, 532 nm green laser pointer, 473 nm blue laser pointer, 593.5 nm orange laser pointer.

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 in it.
Here’s how the projector works:
The green laser bounces off a mirror then through a green beam splitter, the beam is then separated (The reason for this is later I added a second beam turret projector which did not work well so I removed it and also the beam splitter  The Green beam then bounces off a red dichroic filter and into the Scanners. The red laser passes through the red dichroic filter this allows you to mix the two colors into one beam or into dual images if the alignment is off.
(Most all of the video uses the red laser because the green was too bright for the video camera)
Here is some information on my laser system and where you can find the parts.

Laser controller and software I use is from

This is a great package and costs a fraction of any other laser software about $400.00″

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 construction as simple as possible for two reasons. One, electrical engineering is far from my speciality and I didn’t want to kill myself/ruin a laser I could only afford one of. Two, I always hated seeing incredibly awesome projects on the internet that I never had any hope of building due to funds and bizarre parts. That’s not to say you don’t need some basic soldering and construction skills, as well as a healthy respect for the power of laser light, but it’s definitely doable if you put your mind to it.

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 eBay. Besides, where’s the fun in that?

There are plenty of examples of homebrew laser scanners on the internet. Many people have wired up a pair of loudspeakers, hard disk actuators, or other readily available mechanisms to an amplifier and used them for simple laser graphics. This will make some pretty wiggly patterns on the wall, but it isn’t a real vector graphics display. The best example I know of for a totally built-from-scratch laser projector (not using commercial galvo actuators) actually uses custom hand-wound galvanometers. Very nice.

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:

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 friends come over, they are hogging me to get them a free green laser. It’s really something you don’t need but once you see one in real life, you need it.

Hi all,

This is a special review of giant green lasers on the market today.

Since I was getting tired of my little measly 125mW green laser from DragonLasers, I was going to go on shopping for a super-giagantic laser that will fulfill my dreams. (So I can burn stuff from miles away from my 12th floor apartment without getting caught…)
