Probably this weekend. Need to find a green tube, but if nothing else, the bracket will go up.

I don't see an issue on the screen from 10' back, so for now I'm leaving it, but definitely, reducing the output amp gain would solve that issue, no question.

Fired the set up from a cold start last night, it's pretty damn stable. Didn't have it on long enough to check to see if the little drifting comes back in line, but it's well under a test pattern line thickness, so I can live with that.

I'm involved in a computer programming course all week long, may post in the audio section about it. Very specialized, very commercial audio oriented, and should make me a key player in the commercial audio industry locally within a couple of years.. I hope! Now it's all about marketing!

Ive done abit of Media Matrix here at work, but not trained officially, i was wingin it Wink

the latest versions have integration with Ipads and Iphones! No extra hardware needed.. sign in with a browser to the IP address of the Mediamatrix unit, and away you go.

The one distributor went bankrupt a couple of years back, so I bought an entry level Nion unit. 8 inputs, 8 outputs. I wondered last year why the heck I bought it, but I'm now inheriting a really high end client with 140,000 square feet that has 2 of them, with 64 channels of amplification. I need to get up to speed, as I'll need to rewrite the software next year. I'll have my system set up this weekend.

I will have to go and have a look at this setup to see what we have here, its got Windows 2000 on it if i remember right, but channels wise i think its 32, there is four BOBs there, but it is spread across two locations, not sure if theyre both intergrated or seperate now, its been a long time since i played around with it.

Yeah, it's a totally different beast now. you can run 448 channels of audio over 1 CAT 5 cable!

In other news, the second 909 has been retubed, and is ready for the ceiling. Actually, not quite, I'll do the astig magnets tomorrow night while it's still on the bench. Found a near mint 2000 hour green tube with green C element installed that I dropped in. Should have less wear than the one on the ceiling now, and that's pretty damn good. Smile

Do you find the astig magnets a bit of a pain to do on these since you cant really rotate them 360° around the neck? I found that with mine, wasnt really an issue, but its abit less exciting reaching in there the way that second board with the two big resistors spans over the top of them!! Not sure what sort of voltages are around there, i threw my "live switch board work" 1000v insulated rubber mat down to do mine though...

I used one hand and a brand new tight fitting rubber washing up glove 1/3rd of the way up my forearm (different projector though). Isn't that worthwhile at all times?

Always wondered if there was some better advice beyond just using one hand and making sure not to earth yourself?

Im not so sure about the dielectric properties of washing up gloves, but the rubber mat i use is for working on live commercial switch boards, its a safe enough bet you wont be earthed through your feet anyway

Steve,
I just looked up the new material from Seymour. It looks promising and for the price would be a great option. It is to late now as Curt jumped in without asking the pros, but maybe down the road. Razz

I've been zapped so many times, I can't feel 110 volts, and sometimes stick a finger in a live light socket to freak out the girlies. Very Happy

it does vary from person to person though. My first installer back in 1988 was so sensitive to AC shocks, that he'd be out for the day if he even got a little tingle. I don't turn off power to change AC switches or outlets, rewired my whole house to Decora without one flying spark. Got nailed twice though!

As for the AT material, does it have a bit of stretch to it to fasten it?

I still use that myself (watered down with floetrol) and I'm now on a JVC digital. I love my screen (painted curtain blackout material). It's perfect, no hotspotting, colour shift, or anything else odd. Comparing with commercial samples it's about 1.1 gain, maybe 1.2.

The painting instructions I followed I ended up reposting here: http://www.curtpalme.com/Building_a_Screen5.shtm

I've seen lots of painted screens, many of them absolute crap because the person who make it either wasn't very handy or didn't know what they were doing, or both.

Seymour's new Center Stage UF material is only $14/foot for an 84-inch roll width. So, for 11 feet of material, you're only talking about $154. Grommets would probably be another $50 or so, so about $200 all-in. Not sure it makes a whole lot of sense to go buy shade material when for the same price you can get a supported product from an industry guy.

Definitely. Stuff's obviously gotten so cheap it's a no-brainer. I actually had no idea that Seymour's gotten that cheap however, and that's for an AT screen. That's great!

When I painted mine (in 2000), it's because the only other option that was good was a $2000 Stewart screen. I actually painted my screen as a temporary measure until I could afford the Stewart, but when I found out how good the quality was I've been using it ever since.

'Nother question:

I am using an Onkyo TX-SR605 as my main receiver. Picked up from the recycler. Tried the HDMI inputs for 5 minutes, and they work fine, but who knows long term. I also have a Lumagen HDP with super low hours that I won at Cliff's place 5 years ago.

Do I simply use the internal scaling on the Onkyo, or run the HDMI via the Lumagen? Have a feeler out for the new Moome Barco cards, but for now I'll be running into a Moome external box to an RGBHV splitter into the two projectors.

How bad is the Onkyo scaling compared to the Lumagen? The Onkyo makes it easy with one remote (will be Irule down the road), but if the scaling in the Lumagen is that much better, I'll use it instead.

Is the Onkyo using a Faroudja DCDi? Both my Harman/Kardons have that, and having tried it i found it to be more capable than the LiMo PRO, but less capable than the PC, so id say itd be a fair bet the Lumagen will be abit better than the Onkyo.

Ive had some pretty serious boots from mains here with varied side affects, but mains here is 230/400 and will pass through the body a bit easier than 110.

Some people are affected worse than others due to the amount of moisture and minerals in your skin and body affecting overall resistance, but it can take as little as 120mA to bring on cardiac arrest, so its never a good risk to take!!

There was a case that came up during my appreneship where a bloke copped a boot of a building site, although he was not feeling well continued to work, and died from irregular heart beat 2 days after the shock.

Always remember, the biggest reason for safety in the workplace has nothing to do with work!!! You go out and work to enable you a better standard of living, which you wont get if you injure yourself on the job Wink

Ive done a few at work by spraying the screen rather than rolling it, and the results have been somewhat better.

The most recent screen i made at work in the sports bar was large sheet of custom board, five coats of Dulux satin white enamel, no edges or boarders, the projected image fills the screen right to the edges and appears to float in mid air, looks rather impressive like that. Gives a very nice image, considering the ambient lighting conditions i was able to get quite good colour and nice contrast from that, where i had issues with the screen i removed ( which was a glass bead, and formerly home to a Sony VPH-1001 QM CRT many moons ago )

But inside the Barco all voltages are the same. But is there really a risk when turning the astig? The video out board is behind a metal part. Ok in a fault condition that metal part could carry a voltage I guess? Perhaps if you don't connect the ground wires? Good tips.

Deinterlacer with Faroudja DCDi Edge™ so it seems it has DCDi

But wouldn't it be best to do

sources - onkyo - lumagen - moome

or possibly

sources - onkyo - dhcp removing splitter - lumagen and analog to the projector.

HD sound and HDMI splitting using the reciever but having the lumagen to tweak the timings!
