robloxley Posted February 9, 2004 Share Posted February 9, 2004 A scroller with cinefoil in it seems to pop up quite a bit, and is often pretty cost effective. Link to comment Share on other sites More sharing options...
James Posted February 9, 2004 Share Posted February 9, 2004 cheers for that guys: next thing, is there a toy that excists that works like a shutter in front of the lense to create a proper blackout? cheersI can't remember who but someone sugested a great little way of doing this recently on RATS. Take an old possibly even defunct PC CD drive, cover the tray in blackwrap and remote it to a battery and switch in the wings. Quick google later, and it was Mark Mcn to thank for that one.

nickb12345 Posted February 10, 2004 Share Posted February 10, 2004 Hi To put be able to feed a PC output and a Video output into the projector and be able to fade between them live you would need a PC with a Composite/S-Video output (standard on most new graphics cards), a 2 channel or greaver vision mixer and a VCR. If you dont want to do fade live you would record the video into the PC and create a Movie Squence on there which contains the PC based footage and the VCR footage with a fade between - then output this live to the projector. A good program to do this in would be FlashMX if you can afford it because you can create good custom effects and make interactive functions - ie make it do the fade when you push a button on the keyboard.

Suzette Posted February 10, 2004 Share Posted February 10, 2004 We have just built a shutter blackout device for our projector which works a treat!! We have taken the CD tray out of a busted CD player (but the open/close still works) - Filled in the hole in the tray with a thin sheet of ply painted black.Mount the tray on the front of the projector cradle, which is hung from the centre of LX1 to project onto the cyc (basically a tatty bit of off-white cloth - but its the best we have!)Then make up a new cable which extends the control for the open/close.The old CD box sits on the side of the stage together with the video player.Press open/close on the CD player and the shutter moves to one side, press play on the video and picture appears! Projector is a Sanyo PROxtraX multiverse Projector. Model : PLC XW20A (with zoom and keystone), which works fine for our theatre. Distance to cyc approx 9m. Can run video or computer through it, and cuts through our (mainly 1kw) rig fine, but we do tend to run projector with dimmed LX state on stage. We use a 15m multicore run (with S-VHS cable, mains supply and control for shutter) with, so far, no problems. HTH Link to comment Share on other sites More sharing options...
robloxley Posted February 10, 2004 Share Posted February 10, 2004 Filled in the hole in the tray with a thin sheet of ply painted black.I know that not much light comes out of the front of a projector when it is 'black', but the general idea of using wooden things to block light isn't the best. Managed to cause a piece of wood to smoulder very nicely with a knocked-over 60W desklamp once... Link to comment Share on other sites More sharing options...
Techno_Monkey Posted February 14, 2004 Share Posted February 14, 2004 next thing, is there a toy that excists that works like a shutter in front of the lense to create a proper blackout? We had a show that came to our venue last October and they had a CD drive that they placed in front of the projector with an object covering the gap in the tray, and they had managed to DMX it somehow. Not the most attractive solution but rather funky. P.S. does anyone have any ideas on how to do this!? Link to comment Share on other sites More sharing options...
