aは実際にここにある 示すDIYをハードディスクレーザー走査器を造る方法を冷却しなさい 古いハードディスクの束から作られる。

私の最も最近のtinkeryハードウェアおよび埋め込まれたシステム・プロジェクトはhomebrewレーザー走査器である。 、速い壁でレーザ光線を実際に掃除するためにあなたがプラネタリウムで見る種類知りベクトルグラフィックを引く。 商業レーザー走査器は長年に渡って今あったが、完全なシステムを買うことはまだeBayで実際にpricy、である。 その上、楽しみはどこにそれにあるか。

沢山のインターネットのhomebrewレーザー走査器の例がある。 多くの人々は組の拡声器、ハードディスクのアクチュエーター、またはアンプに他のすぐに利用できるメカニズムの上でワイヤーで縛り、簡単なレーザーのグラフィックのためにそれらを使用した。 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…)
