Saga of the "Old Vic" - Page 29

post #841 of 1144
Hi Moggie.

What an amazing experience it has been reading through your entire thread. Your level of commitment to this project just astounds me. But better yet you have given me some great ideas for my future HT - star ceiling, DIY masking system, LED light in columns and many more! You really deserve many great hours down there with your family reaping the fruits of your labor.

In the meantime though, how's it coming along with that movie of yours?

Cheers.

Thanks Chris. It's been a journey for sure! I'm glad I've inspired you over there in Denmark, I've certainly been inspired by many of the builds here a couple of years prior to starting on my own.

My home "making of" movie ... well, I have to completely finish the build first My nature is to finish what I've started so it will get done at some point. I'm not sure how many people it will interest outside of you and my friends and family though.

Moggie, I LOVE your theater and I always look forward to your updates. Stay with it, man! We're watching, even if we don't post often!

Some progress to report -- last week I received my Prismasonic HD-6000R lens which I believe to be one of the first batch to arrive in the US. Unfortunately the lift mechanism didn't work. I must say that the Primasonic support was incredible and after an PM exchange on Monday night I had replacement electronics in my hand on Thursday all the way from Finland!



I was going to finish off the hush box and lens mount this weekend but I got side tracked trying to get the columns finished...

I didn't want to have a large support in front of the surround speakers so I decided to make the columns panels in three sections. The top and bottom curved to follow the contour of the walnut sides and the center a box plug to surround the speakers.



Rather than use 3/4" wood for the front support I use some 3/8" aluminum angle and epoxied in some wood triangles to increase the stiffness. It worked out great -- stiff and very thin.

Then all the frames and curved panels we sprayed black and covered with GOM FR701.



I manged to get the upper two panels fitted (with Velcro) before collapsing after a very long weekend.



One other extra detail I'm working on is way to improve the way the columns meet the floor. I wasn't happy with the way they terminated at the carpet so I made some little feet. Still need to get the finish on them but I thought they were cute.



In case you are wondering I'm now at 70 hours on the projector so am finding time to enjoy the theater..

Yeah, I love walnut too. Probably one of my favorite woods too although I wish it wasn't so expensive.

I cant wait to hear your review on the lens. I got on the waiting list but really wanted to hear some real reviews before I take the plunge.

Scott, yeah I'll definitely post comments. I'm actually just about to go down to the shop for a couple of hours to work on the hush box .. fitting both the lens and projector is turning out to be quite a challenge and I need the box in order to hang the lens correctly..

I still have access to it via the hatch to my star ceiling illuminator. I would need to check code before doing this. The final option are these special dimmers for LED's that work very differently from a simple power supply and will guarantee smooth dimming and immediate turn on. The problem is that I need to know the exact quantity of LED lights to size the supply correctly. Stay tuned.

Hi Moggie. I am looking at the Elemental LED strips for step lights on my riser lip. I've been unable to get confirmation that it will work with a Grafik Eye from Lutron or Elemental tech support (see post on the GE thread here).

I was looking at the Elemental dimmable 20W power supply (I will only be using ~6 LEDs total). The ROAL model you referenced above is MUCH less expensive ($28 vs. $110)!

Did you end up with an Elemental setup that is Grafik Eye dimmable, and if so can you provide the final details?

Thanks!

Hi Dan (I presume). Yes, I did go with the ROAL power modules. For low voltage LED's it is the power supply that allows for dimming, not the LED's themselves. You do need to make sure you get the right rating if you want the LED's to dim correctly. Specifically you need to work out the total wattage of your LED's and get the power supply of the closest, but greater, rating.

The only thing to watch for is the minimum per circuit load required for the GE to work. I believe that is 20W but you should check Lutron's doc. If you are larger than this you shouldn't have any problems. My LED's dim just fine although of course, they do suffer from the "pop on/pop off" problem common to all LED's -- i.e. they only dim to about 10% brightness then cut off, and similarly don't come on to a similar value. From 10% to 100% they are perfect.

Hope this helps.

Confirmation of a working setup helps tremendously, thanks!

The minimum load for a single zone with Lutron GE QS is 25W (from install doc). I'll be using 3 LEDs (2") over each of four steps, so the total load will be under 1.44W (Elemental LED is 1.44W per foot). So I'll need the LUT-LBX synthetic minimum load.

At 15W, the ROAL power supply is closer to the actual wattage than the Elemental dimmable power supply (20W). Although the ROAL supply price increased from $28 to $32 over the past two day, it is still much less expensive (Elemental is $110)!

With the Lutron synthetic load you won't have any problems.

Intermixed with 4th July celebrations I was able to just about finish my hush box this weekend. I still need to make and fit some trim along the seams but it's 95% of the way there. I also encountered a problem with the a-lens lift...

I had built the basic box about 9 months ago when I built the soffits. Now I have finalized choice of projector and a-lens I tried to stuff everything into a rather tight fitting box. It would have been nice to have had a bit more space but I was backed into a corner so I had to hack and slash the original shape and mold it to the unusual profile of the Primsmasonic HD-6000R lens and lift. I tried to keep the maple and walnut theme and after playing at the table saw and router for a few hours I came up with this:



After another day and a half of finishing and mounting here is how it looks now. The lens porthole is designed to take a piece of optical glass if I decide to seal it off. I would only do this for dust reasons because the projector was already quite and is now completely silent.



The lid it held close with a couple of draw clasps (like a trunk) and the air intake filters were obtained from McMasterCarr.com and embedded into the maple.





Note that I used up the remains of my insulation covered with scraps of GOM in the lid to help absorb the noise. I also routed in a seal around the lid to improve sound isolation and venting. Behind the projector is also a baffle to prevent short-circuiting of the cold air to the return. I'll take a picture of inside the hush box when I remove the projector to fit the a-lens.

Those of you looking closely at the pics will see that there is no a-lens in place! The Primsmasonic lens looks really nice, but I am having my fair share of problems. First it was a dead remote control, now after mounting and running the lens up and down a couple of times, one of the drive motors looks like it stripped a thread.

I had made a mount that would allowed the lens to be suspended directly from my ceiling (roof of hush box) -- the HD-6000R is designed to be mounted on a shelf or with custom attachment to the projector mount. It seems to me that it would be a good idea if Prismasonic supplied mounts similar to mine with the base unit -- they would be extremely cheap to produce.




Anyway, after a couple of lifts up and down I was about to set up the focus when I heard a crunch and the lens froze. Back an forth movement would not free it so having just mounted everything I tore it all down and dismantled the lens. You can see the one side where the motor no longer can hold the weight of the lens.



I've pinged Anssi at Prismasonic to see how he wants to handle this, but I'm really bummed right now since I'm back to 16:9 and cannot zoom anymore since the hush box porthole is not big enough. I'll review the lens and mount just as soon as I can, but at this point I would say that the lens looks solid but I'm not so sure about the lift...

Brilliant stuff moggie!

Do you have a couple small fans connected to the grills at the back?

Cheers,

Thanks Simon! No fans -- just passive fan covers. They are both 6" diameter and located near to the projector inlet fans so there is plenty of air flow. After running the projector for a couple of hours today I opened the box and it was surprisingly cool.

Moggie,
Bummer on the lens mechanism. As for that hush box - excellent engineering and finish work
post #861 of 1144
Moggie i'm pretty excited to hear your review. I have been zooming and know that a lens will put my setup over the top.
post #862 of 1144
Schweeet Hush Box Moggie!! The router work on the Mahogany looks Great.

Thats a bummer for the lens motor.. Hope they resolve it in a timely fashion.

I have the previous HD5000R for ~ a year, fortunately no issues .. the cardboard box its in has just sat in the corner and not casued any problems yet

Thanks Brad. You know, components rarely fail inside their cardboard box! That said, didn't you say you have your hush box and projector mounted? You haven't mounted the lens yet?
post #864 of 1144
Yup.. The box is hung, the projector and lens were in for long enough to find out I needed to cut the front lip off of the box, then I packed the lens back up for safe keeping until........

Getting the "port hole" right for the box is not as easy as it sounds. I only just squeaked in and I thought that I had measured everything three times. The only limit I have now is not being able to zoom beyond 16:9 since the projector is set back and the corner of the image clips the opening. If I had made the opening any larger I don't think it would have looked right. I guess I'll just have to wait for the lens.. eta middle of next week.

Ummm.. Let me get back to you on that

Question for ya.. I had read that the AR glass for the porthole should be at a 7-15 degree angle to keep reflections from degrading contrast/image sharpness.. Do you have any concerns with this or does your projector angle enough to aviod the issues if you put the glass in the porthole?

Moggie, one important thing I forgot to ask... can you confirm that you are using the Roal driver "directly" connected to the Grafik Eye (i.e no extra interface), and which GE output channel setting you are using?
