Show off your Laser projector !

Wow, that's a lot of free space ...

**frito** · 09-17-2009, 02:14

Hey thanks i know that some don't like the idea of the pelican case because it gets hot inside. But im putting 4 strong brush less fans so it should keep the inside cool. Hey Laserjock i really like your set up it looks very clean. is that like some type of disfraction glass you have there, well i really like it . i cant wait till i finish mine, it is hard for me to aligned my diodes w/ the dichros and scanners i been trying for the past 2 days. If i cant do it i guess im going to have to find some one local that i can pay for them to do it i know it sux but im tired and also i dont have any eye protection.

**Lazerjock** · 09-17-2009, 07:21

Frito,
I think you should be fine as long as you keep air moving. My projector has 2 high volume fans blowing across the electronics.

The disk to the right of the scanners is a Lumia wheel. It's just a piece or textured glass mounted to a slow turning motor. It gives you a 3D moving nebula type effect. The black rectangular boxes are GM-20's. They are used to steer the beam to different effects like Lumia. The second GM-20 is to select my Machita diffraction grating. It creates hundreds of beams side by side. I didn't have it installed at the time I took the picture.

Thank You for the compliments.

Hi People

Here is a photo of my little collection of Projectors I have amassed together.

Attachment 9520

On the left is Little Stan with one of the Green twins sat on top. On the right is Old Jem with the other Green twin.

The spec of them are as followed.

Little Stan.
750mW RGB.
Red : 400mW 650nm Laserwave
Green : 200mW 532nm Laserwave
Blue : 150mW 473nm Laserwave
DT40 Pro scanners

Old Jem.
700mW RGB.
Red : 200mW 642nm Laserwave + 250 mW 671nm CNI
Green : 150mW 532nm CNI
Blue : 100mW 473nm CNI
DT40 Pro scanners

The Twins.
532 nm Greens with DT25s. One has a CNI 150mW doing 250mW+ and the other has a 300mW Laserwave. The CNI for some reason seams to outperform the Laserwave.

Enjoy

Not sure how much current you're drawing with your rig,but you might want to figure-8 coil your feeder cable. knocks out the inductance.

other than that, yes, I am very jealous.

**Misebeam** · 09-21-2009, 00:38

Hey thanks for the info on the Distro, I pull about 24 amps at full current single phase. I always take all of the cable out of the case when run it. I ran across "issues" the first time I ran it

lots of heat!

Anyhow THANKS!

**Mr.Coffee** · 09-21-2009, 10:09

yeah, that's from the inductance. if you figure 8 your cable, that'll cancel out and you won't have issues. a small figure 8 infront of your cable box will look nice and will keep the casters in place so it doesn't run around on you.

Also, pulling the cable out every time you use it is good practice anyway, it makes it easier to notice damage (should there be any).

**frito** · 09-22-2009, 02:01

hi guys im almost done with my project it took me a long time to adjust the diodes but its finally done. need to go buy more fans and fan grills. but im not that satisfied its still not giving me a solid white... what do you guys suggest i do, should i get a stronger blue like a 150mW 473nm?
Dont make fun i know is I-Show! IM A NOOB...

300mW 650nm Red
150mW 532nm Green
80mW 473nm Blue

This is my DIY laser projector. Galvos Laserworld LW-50, laser 150mw 532nm, sound card DAC.

That's a cute little projector.

**Things** · 09-25-2009, 09:12

What's with the SLA batteries?

Is it portable? What did you use for an inverter?

Bridge, I absolutely LOVE that plexiglass case, I want one!

**sopkis** · 09-25-2009, 09:27

Yes, this scanner is portable, it can run from batteries, or from 220v. When it run from 220v, it charge the batteries. The power stage is - 2x 12V 7Ah SLA batteries, Titan 75W power inverter (12V to 220V), battery charging circuit (14V 0.8A mc34063), original LW power supply to galvo drivers (+24V 1.5A(used to charging battery when working from 220V), -24V 1A).

^^^ what he said ^^^

Are those bounce mirrors servo'd or do you set them manually?

I didn't have a chance to look through all of your pics, although I have see those albums before. Do you have beam shots by any chance, I dont think I have ever seen any!

Also, your label says that the Maxyz module is 680nm, however, if memory serves me correctly its 658nm... 680nm would be almost invisible. Just something I figured I would bring to your attention.

Best regards,
Max

**mliptack** · 10-26-2009, 13:00

Liteglow, if you don't mind (and you still have the link) you should link these guys to the projector you based the idea off of. I think its a great idea personally.

**liteglow** · 10-26-2009, 18:42

Hi,

Here is some more photos (of the build)

http://liteglow.vox.com/library/photos/page/1/

And my gallery with some other photos:

http://s468.photobucket.com/albums/r...low2000/Laser/

Yes the idea was from the Award Winning ShowLaser:

http://www.lasernet.com/whatsnew-200...amraider-award

I thought the idea of have a special laser sounds fun

And to create crossover patterns with only one set of galvo is a good idea!

I want to complete my laser, but sadly I`m out of money...
And because my maXy RED laser died, the RGB have been under the dust the last 1-2 years now

**mliptack** · 10-26-2009, 19:11

Even though you said the funds are gone.. I just wanted to alert you to the fact that I have an almost never used (saying even 10 hours on the diodes would be a generous estimate) Dual Maxyz unit that I might be putting up for sale in the next few days/weeks.

Due to its excellent condition, I am hoping to get close to what I paid for it.

**mliptack** · 10-26-2009, 19:13

LiteGlow, whats with the laminar flow water jets in the blog, if you dont mind me asking?

Thanx for the reply

The water jet is a project I have been working on all summer\winter .
And it will be finished summer 2010 i hope!
It will includes 2-3 Jumping Laminar jets with fullcolor water beams.
And with cutter included.
They will jump into a pond in my garden, and in the pond I will place a tiny little beautiful fountain (damn now I remember where all my money have gone)

You can se my video on my YouTube http://www.youtube.com/watch?v=x-zgt...er_profilepage

And many more videos

And if you are interested, you can see my project on the laminar forum that I did create: http://laminar.forumotion.com/lamina...g-jets-t57.htm
It`s all homemade :-)

Btw, because of the failed mAxy modules I had, i think I will uppgrade to something bigger next time (when I got the money) !
I need 500mW+ (i had 400mW and the red was not so visible in the clubs)

Haha that GREEN 1.5W outdoor photos is something I did long time ago (have more photos) !
It was more like an see_what_I_Can_Do_photo that I did post on CPF :P
Just because some dude was banned of posting a outdoor picture of an green laser pen into the sky, and the admin have rules that NO photo of an laser into the sky haha..

And after that the PHOTONLEXICON forum was created

and i can almost guarantee you yours is built better, they got a lasernet projector at the Miami museum of science, paid $50000 for it, and its the biggest piece of crap... all the lasers are out of alignment, the scanners can BARELY do 24kpps (the ILDA pattern doesn't look "OK" till about 12kpps) the reds look like spotlights, the blue jellybeans worse than any other blue Ive ever seen, and even their green jellybeans!

ANYWAY

here is a link to my projector worklog

eventually it should look like this

**c4r0** · 11-03-2009, 15:48

This is my first post so ... Hi everyone

I don't have any projector that is compact, mobile and packed in a casing because I'm still working on something with setup

So the thing I can show you here is my recent achievement which is a small (35mW) RGV laser projector that I put together on my desk

The lasers are DVD-RW diode, Xbox360 HD DVD diode and 50mW green pointer. Galvos are GSI G100PD. I'm planning to build something more powerful in near future, so maybe I will post in this topic onece again someday

LASERJOCK Thanks!

Almost finish Guys!
