It all started about 20 years ago when i visited a local Swiss Disco called Crystal Palace.
This was the first time i saw a Lasershow.Beside the beamshow my favourite part was the graphic show Walk Like An Egyptian.
In 1990 i could buy 2 second hand Melles Griot red HeNe lasers with a estimated output of 10 mW.
Then i purchased a Jem Fogger and all the toys from the German ELV company.(LA90 + LSI 7000 , LS90 + LMI 7000 , LI90)
A year later i visited the Laserium at Griffith for the first time.I was blown away!
The 6 more holidays i did spend in the Us the following decade always started with a direct flight Zurich to LA.
After the hotel check in the first thing to do was to enjoy a evening show in the Laserium.
I saw a lot of other great lasershows in Vegas,San Francisco,Orlando,London,Planetarium Munich in Germany
and in eastern Europe,but appart from some aggressive beamshows into the audience i liked the Laserium shows the most.
So i was very disappointed in my last holiday in the US in 2002 when Griffith Observatory was closed for renovations
and even if they reopen there will be no more lasershows.
So my question is if there are other places in the Us or elswhere with such lasershows??
My last relapse was 3 weeks ago when i got a good deal for a Laserworld RGB Projector with 300mW 660nm, 150mW 532nm
and 100mW 473nm.
I already read in this and other forums ,so i knew that i don't buy a Roll Royce and there is a lack of blue and red.
But since i'm using it in a small room of 9,5 x 4,5 meters and it comes with analogue modulation,USB interface and software
for 4100 US$ including costs for shipping and custom,i couldn't resist.
I used it for about 15 hours and it complies mostly with my expectations. I'm sitting 6 meters awayand the green is
a bit aggressive.So i reduced the intensity of the green laser and now also the RGB balance is good for me.
For beamshows i create figures that come close around me but don't hit my eyes.For Graphics i have a silk like fabric.
One thing is still bothering me a bit and that's the beamshape of the red diode laser.I knew it's different to the DPSS models.
I drilled a 2,5 mm hole in a plate and placed it in front of the red laser.For beamshows it's okay but for graphics it's still disturbing.
So if I stay a longer time with this hobby i could replace it with a red DPSS or if a desire for more power appears
( usualy only a question of time) i could upgrade to 200 or 300 mW Blue
or maybe build a second projector myself.
At the moment i'm still busy with learning to use all the features of the software.But i'm sure there will be more questions
where i'm glad to get some good advice from the members of this forum.
