这真正地a 冷却显示您如何的DIY修造硬盘激光扫描器 由束老硬盘做。

我的最新的tinkery硬件和嵌入系统项目是homebrew激光扫描器。 您知道，您在墙壁上看见在天文馆清扫激光真正地快速的种类，并且画向量图形。 商业激光扫描器现在数十年，但买一个完整系统仍然是真正地高价，甚而在eBay。 其外，在哪里乐趣由于？

有大量homebrew激光扫描器的例子在互联网。 许多人架线了一个对扩音器、硬盘作动器，或者其他欣然可利用的机制到放大器并且为简单的laser图表使用了他们。 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…)

Now this may be considered good by some people and really bad by others, but whatever the general consensus of opinion this thing is out and no doubt somebody somewhere is using this to spy on someone else.

This device uses the lobster vision, which is exactly what they say it is. It uses the same principle of vision as a lobster would to find its way through the murky waters.

But there are issues here too, the devices uses a type of x ray, which I believe could be extremely dangerous in the wrong hands or even the right hands, so should this device be available to just anyone? I hope not!

The long awaited return of Knightrider will soon be upon us, but the star of the show has always been the car named KITT rather than the star named “The Hoff”.

Some of the features of the new KITT are the following:

Laser weapons system,
Nanotech cloaking,
Laser-guided missile defence,
3D heads-up display,
Military-grade GPS,
Holographic projection
And even a Mini-KITT reconnaissance drone (whatever that may be?)

Which is ok, but what about the jet thrusters?
