Thank you very much for the lamp defocusing tip, thats excellent!

Hi, going to try and post a picture now....

[wylie-cayote]

Shows the 4K-23B with Panny Blu Ray DVB-C tuner for the cable TV, a temp mounted Kaleidescape player, the rack in the rear has the old Bryston amps and Lexicon processor and Kaleidescape server, loads more to add and change over.
Projector pic is cut off a bit by fuse board on right, the ventilation fan in this pic mounted on ceiling with the exhaust tubes doing torturous route, but has already been replaced with a new fan unit that sits on top of the PJ with a stainless exhaust going straight into ceiling void where the hot air is exhausted through ceilings by other fan. The port window is being replaced (not in pic) and the wall plastered again!

Still stunned by calibrated picture quality of the Barco.

The mass of purple CAT 5 behind the rear Middle Atlantic rack was once a Netstreams home audio distribution system. Room is still a bit messy but added new LED down lights and bits and bobs.

Under the projector table is the UPS for the systems power, hard to see.
We are controlling everything via an AMX NI-3100 processor and iPad. Timing is critical.
The PJ systems power comes from the output of the UPS through a 230v / 12v triggered relay. So "on"sequence is : Switch systems relay on / wait 240 secs - allows time for all PJ systems to boot - display on iPad "system starting up- please wait - IP command to PJ select preset 1 (or whichever icon was pressed on iPad) this fires up source macro, triggers curtains to open, lights to dim (level depending of source selected), sets Screen curtain (16.9 / 2.35) via RS232,  Lexicon preamp RS232 command on and preset volume level, the Lexicon auto triggers via inbuilt relay the Bryston amps,  and finally dowser opens (sequence on macro).
We originally had a 480second delay on start up, but having tested time and time again, the systems processor is always ready within 150-200 seconds, so added a wee bit for safety! Also the 480 seconds took for ever, well 480 seconds - boring looking at a curtain for that time!
Took a lot of time on AMX programming (not me, but my programmer) as essential that if someone closes the iPad program or its battery drops that when it is reinitiated that the program knows where it is at any given point. So page tracking, interpret feedback from PJ as to current status etc, this needs particular attention or a complete reboot is required of all systems - not nice and time consuming.
On switch off, iPad displays, "are you sure you want to switch off?" if "yes" is pressed, then "system shutting down" -sound, pj off etc with a countdown timer on iPad, and this sequence takes 1300 seconds before you can reinitiate - this is to ensure that if the PJ has been on for several hours that adequate cooling takes place - a bummer if you remember that the rugby is going to start in ten minutes!
Hope this isn't boring!
The lamp power supply constant obviously.

Looking good. What brand projection cart are you using, they are common over seas but rare here in the states, I like those. Congrats on the control system. Converting something not meant to be controlled with a typical IR remote into something user friendly for the consumer is important and not easy to do. I need to tackle next for myself..

I am curious if we will see a Laser retro kit in the future for the Barco. Not that there is any immediate need rec 2020 & HDR does interest me.

Keep us posted on your progress you have an already top system.

I built the cart myself, bought some 19" racking bars from a manufacturer in north of Portugal, the vented side panels (not in pic) were pressed by a mate of mine in his factory in Holland. The top is 25mm thick MDF screwed into the steel box frame and sprayed black. It doesn't have wheels but does have adjustable levellers on each corner. The Barco cart retails at €2000, this cost me €380 in materials plus some time in my workshop.

Good work on the cart.

I just heard from industry insider who attended Cinemacon a Blue Phosphor Laser retro is coming for the Barco. 11000 lumens.
