NORBERGFESTIVAL !!!

Hey! Do you know this guy?

I am not the one to answer questions about making your own solid state lasers. I've never done it. But there are others on this forum who have. Forum member drlava makes a tiny device that provides the correct power to these laser diodes. It has the analog modulation you need. You can use this with any of the red diodes, the BluRay diode or the IR pump diode that makes a green DPSS laser light.

If you choose to make your own lasers, he can tell you a lot more about it.

well enough for today. sleep is to take place. but i will write back as soon as possible with further questions.
thanks for the answers they help!

[James]

Do you know dar303 from above linked post?

I'm sure he can tell you a lot!

James. 

[johannesgj]

yeah i think i know him.
if i do then the name dar303 must be short for
daniel arraya 303 . 303 refers to the campingstage.
camp 303 has this hell of a big smoke machine and then he uses his homebuild projector to blow out some wicked beams.

its always a pleasure to visit norberg festivallen and now im even a part of the board.
yeah will just ask him now.

btw we just got asnwers from the youthhouse and they say there is enough money to buy the solid states. but only if the solid states maches the circa prices written here:

Green laser: $150
AL Baseplate: $20-$50

for starters and then to go RGB:
Dichros and mounts: $100-$150
Blu Ray laser: $60-120
Red Laser-$60-$120

again a short question. and sorry if i keep scrolling around the same circle. the lasers have build in controller boards and so does the galvos if you choose. and these controller boards just need to be connected to the soundcard?

thanks

[johannesgj]

by the way.
im totally blown away by the 3d effects these projectors can create . on a black background you even get tricked into beleiving it is actual 3d. another thing. as i see this nice 3d effect would if be possible to port some old games like astroids or something to output using the lb format? or is it impossible to output using the lb format without first compressing it in this format.
or dais shortly can you project live video or is it only preformatted material?

and again
these laser beams are WICKED

[drlava]

you will probably have to do a little assembly to reach a few of those prices, but it can be done.  Yes, the lasers will have controller boards and the galvos will also so they get connected directly to the sound card DAC.

There is already an asteroids (laseroids) program written and with my EzAudDac driver you can play it with your sound card DAC.  There is pong, also

[BlinkenLights]

and if you know how to use mame (an emulation program) you can play tailgunner and other Atari vector classics

[johannesgj]

well thats just even nicer
i have been playing mame arcade games for some years so it shouldnt be hard to implement. and you say there is a specific driver to use with atari vector games. well thats just incredible.

i think that i now have enough knowledge to begin using the allready made strings on subjects like dac's and lasers.
thanks for giving me the initial understanding see you on other strings

and btw. when i start i will document the process plus put up a whole page on the build at my site. and of course also here

I what I wanted you to see!

I knew it was Alfa Romeo who posted the pictures, but I couldn't remember where they were.

Check out the whole thread. He's got some fantastic pictures of his own home made projector.

These pictures should explain a lot about many of the things you are asking.

James. 

[johannesgj]

thanks! :-)

[johannesgj]

hey again. thought this was a good thread so i started it up again.
well my question is that i found those nice looking galvos here:
http://lasershowparts.com/store/index.php?_a=viewProd&productId=7
and here a review:
http://www.photonlexicon.com/forums/showthread.php/4962-Review-of-ScanPro20-scanners-from-LaserShowParts-com
its about the scanpro 20 gavlo kit.
ive had a hard time finding cheap and good galvos and this is by far the cheapest option i could find. well all in all it is a normal set of galvos with some dmx control board connected to them. well
the problem is that it says it is not ilda compatible.

another thing is that as i see it i dont need the dmx board as i am going to connect them galvos to some diy or laserboy forum promoted controller. well
any thoughts are welcomed !!!

[johannesgj]

btw is this a good buy?
http://global.ebay.com/ILDA_Breakout_Broad_with_Laser_Galvo_Scanning_20Kpps_/120502784660/item
its the scanpro 20 in a package with an ilda breakout board all for 150 dollars.
well i desperatley need to know what the prices on this kind of hardware is supposed to be.

thanks
