this is the guy talking who's programming the "beamer sound to light" program - get the 0.5 version without some main features of the upcoming (free) release there. the main point of his posting is: "there are more things to code than i've planned. it's done when it's done" @jake fielder: no i am not "martin fricke". i'm just on the same forum (there: "fox"). on the youtube account of "klomeister123" (martin fricke) you can see a video of a projector in action while there are scanners being used at the same time.

The thing about projectors is that you have to spend big money to get anything remotely decent. Sure there are a lot of cheap projectors now but if you look at the usual suspects Sanyo Xtra standard, their still about the same price. There's no point sticking in a brighter bulb if you don't have the optics or chips to do them justice. I've recently seen my old Sanyo 800 lumen projector show up a Cheapish 4k. There was no contest and the extra 3.2k just seemed to go into washing out the image lol.
PS - Decent projectors might be cheaper to initially buy than decent lasers but don't forget about replacement bulbs... usually around £300-600 a pop and different lenses (if needed). That said you'll never properly emulate a decent laser. I have a mate that used to build his own 1 and 2 watt lasers which were fully programmable by machine and nothing I saw came close to them apart from the really big laser shows. He was based in Stratford though. |

I can't help thinking that peeople are seeing this from the wrong angle, it's not about emulating a laser - just using a projector in a different way as another light effect. Something different for the sake of it! Obviously if you want a laser you buy a laser.
As an aside I bought a new bulb for my LCD projector the other month, cost me £200 as a I found one reduced from £300. I was pleased. |

Sometimes if I'm low on lights I use the big projector + itunes' new visualiser that's reactive to the built in mic, looks beautiful.

The thing with lasers is that realistically you want to use them for about 10 mins every hour or so to give that 'woo' factor over the night. However promoters have often shelled out lots of money on hiring them in if it's any good, and so every time they walk into the room and see no lasers it's like 'WHY IS THERE NO f**kING LASER??! IT'S COSTING ME A f**kING FORTUNE I WANT TO GET MY MONEYS WORTH' And all the time the laser is on it means the lighting guy has to watch what he does so as not to white out the laser.
Dunno if anyone saw Robbie Williams at roundhous ethe other night but they obviously spent money on some lasers, but used them appropriately for a single song as far as I could see. Exactly as intended, a special effect. You don't see many gigs with 10 hours of solid pyro now do you...

Heres one for you
My 12k Christies can store presets for zoom and focus so I can Project onto a front screen behind the stange and the other one I did exactly the same at the other end of the room.
then for 1 of the bands songs we hit preset 2 on the wired remote on the back projector it zoomed right out and refocused for the haze at stage end and then through arkaos did a lazer effect - Yeah Norty anything less than 5k and it would look pooh - didnt get any photo's as was a man down due to an empty promise from the client (yeah I will have loads of bodies to help) My arse....
but will get some footage so I can put on the website....

Uummmm,
Have I missed the point somewhere here.
Most if not all projectors can and will connect staright to a PC, either as a monitor or via USB. So why does the laser sim program convert DMX to the projector. I went to the laser sim page and was expecting a bit of PC software with patterns already created that you could drag and drop into a timeline to create a show. Just a PC and a projector. I would have downloaded it and been having fun right now. But DMX, why. You have frightended me off. I've got a PC and I've got a projector, its simple. I want a PC program to make pretty patterns so I can blow my mind with a smoke machine and my projector. Why did you have to bring DMX to the party.
Best laser I ever saw was in 1991 at the Academy in union street Plymouth. Opus supplied the sound system and I was standing on the balcony taking a break when this large red ovulating circle appeard infront of me. Then a yellow triangle appeared and slowly zoomed in and out of the circle. Then followed a blue box that also zoomed in and out and also started bouncing off the yellow triangle. This went on untill there were 6 objects of differnet colours all dancing, zooming and forming new patterns within the ovulating circle. My mind was totally blown away and I just couldn't leave from where I was. Talk about engaging. And I wasn't even on any drugs.
So yeah, the fact that I remember that night means a well programed laser can be about the best mind altering effect money can buy.

They were the Martin RGB1.6 lasers
Nice units, but needed a little more time in the R&D dept in my opinion.

Nice units but WAAAY overpriced for the spec. Getting 1.6watts of decent RGB white is only going to cost £5k or so, plus decent scanners max another £1k, plus assorted safety boards, case etc Didn't Martin want somewhere in the region of £40k when these came out? Have a look at the Kvants and tell me they aren't very similar units |
