Lord... Yeah, app or, no matter what device you're on, just go to google and type in "6m in feet", and it will convert for you.

We've had this convo before regarding screen height. Your room is atypically tall compared to most in the US, which are only 2.5-3m - sometimes less. That helps significantly with your heat gain. My room is barely 2.5m tall, so any heat is noticeable much more quickly.
Regardless, 2000 BTU isn't trivial. That's approximately the same heat output as the 600w low setting on my space heater. For comparison, humans at rest dissipate about 100w or 350BTU. So, my G70 was almost like six bodies in a small space. With six people in there, it was a double-whammy.

That's nice for you, but for the other 95% of people here, they have to pay for the electricity to run the projector, and for the electricity to cool the room. The projector is a relatively trivial cost in the grand scheme, but the A/C is not. It's not a big deal, but it's something to consider in the "this is cheaper, this isn't" comparison.

Amen to the last part luckily for me my viewing room stays a constant temp and my Ecp barely makes much of a difference in temp(unlike it would be having four to six people in the same room with the projector running)
But it is true not all of us have the luxeury of having our house ran by solar(plan on doing it with my work building though it I can)
Ecrabb I own(and use) mostly apple product(except my media machine/dvr pc in my bedroom) but there is a app for conversion on my laptop so no need to search the web for it
Case ecrabb has a point about your room size I am lucky to have the 10 foot diagonal screen I have do I wish I could go bigger yes I do but I am limited to the room size and the projectors(and its lens) ability to work with the the screen(almost at the limits of the lens adjustment on my Ecp as is)now my nec has a bit more wiggle room on the lens adjustment for a larger screen(not that I can or want to go larger anyway right now)

I paid for the solar, it certainly wasn't free!! But in taking such initiative, I can now use what I like without the fear of being charged for it.
Electricity prices in QLD ( which is the state I reside in Australia ) are about to rise from 27 cents to 30 cents per kWh, im lead to believe that is considerably more than you pay for it in the USA. Ofcourse there is a heap of people complaining it is people like me with solar installations that are causing the higher prices "cause we get it all free" that fail to take into account the fact that we outlaid a substantial amount of money to install the solar systems in the first place. I outlaid the money because it is very obvious what inflation will do to coal power generation sell prices, and im over half way to having my initial outlay returned to me in just 3 years, not taking into account I use as much power as I like now instead of being conservative with it.
So while you're right and it is nice for me, I also work 2 jobs and saved hard, then spent a lot of money to ensure I don't need to worry about future rises.
I can also run my air conditioning system on full power in the hottest part of summer when temps here can hit 45*c and more, knowing that im not using the power from the grid that others may require for their use.
I would say my average daily export to the grid would be around 13-14 kWh and has been as high as 23 kWh, average daily import from the grid would be 3-4 kWh this year due mostly to poor whether requiring me to boost the hotwater system most days. Last half of last year I got down as low as 4 kWh per day consumption, which is quite low considering I have on-site waste water treatment systems that run 24 hrs a day. I intend to hit 30 kWh export in one day in the next summer period when I add another 3kW of panels to the current installation.
As for the room size, yes I do remember discussing this with you some time ago Crabb, however this was simply to indicate to Big E the size of the room. 9ft ceilings are quite common in Australia, I live in a steel shed on 7 acres of land so I can have whatever I like

There is more you can do to save energy than just solar power, lots of places you can save especially when building a new place.

I know how soler panel systems work the electic company pays you(the soler panel owner) for what you produce but don't use that gets put back in the grid(there is some soler panel owners in the us.

Also I am planning to also do a battery bank with the soler panels and have my work shop building completely off the grid

You dont want to do that, itll cost you far more than youll ever save. Youre gonna need alot more batteries than you think.

After posting my post it made me think of the dead ups that need batteries(it changed my mind real quick) but it wouldn't hurt on the lights(useing led bulbs) should the power fail at night and I am putting a computer together
I didn't have my morning caffeine when I posted(go figure)

The cost of the LED lamps to get ones with decent brightness and colour rendition is quite outrageous compared to fluro lighting, however depending on the inverter you use you will probably need to use dimmable electronic ballasts instead of iron core units. In my experience, domestic LED lighting doesn't go the distance either.

Back to thread... I know Case you have big hopes in this Cine max, but at least you will have the NEC also, so if you'll be disapointed you still can put the tubes in the XG

Oooh you don't have to get the yokes on, they probably match in impedance (if not you'll make it to match) just have to solder new connectors at the end

I'll happily trade the cold beer for a plane ticket, otherwise agreed

heh, why not throw a PG-party.
We'll all just take our PGs as hand luggage in the airplane and build a mega-blendstack

Well if you can convince Aussie_Al, he can bring four more PGs, and be here within an hour!!

led is better then what it used to be(can't say the same for the fluorescent lighting)but i have led lighting in the track light for my home theater and they are pretty close to matching the old style bulbs in brightness(aka lumens)which would be a par 20 halogen bulb
the rest of the room has been changed over as the cfl bulbs turned part of my screen yellow  that is a odd thing to have happen but it did and i had to redo my screen because of it it wasn't hard as my screen "floats" so to say (suspended by small cables which disappear in low light)above my equipment and center speaker
don't ask how i leveled it up like that but i did i have been thinking of doing a black felt border but haven't had the time to take the screen down and not sure if i want to put it on the screen and it suspended (it takes two people to work with it)

now that i would want to see a pic of  both of the sets and the screen shot with the results
i will try and get a screen shot of my ecp and nec 10pg as soon as i get the later one fixed and replace the failing high voltage power supply in my ecp(which has stopped arcing for now but dims the tubes when bright images are shown at least it isn't scaring the crap out me like this  )
fuchs explain how you be able to lug a projector onto a plane as hand luggage i can image peoples faces now as they see your machine(considering most people has no clue what a crt projector is  )

While i do agree for the most, fluros have become somewhat less reliable, they are still a better lamp for the cost involved, at least here. They should always have a UV blocking diffuser fitted. Part of my training as an electrician here in Australia is lighting, and where i work a decent share of time is given to lighting, and selection there of. Having tested more than 100 LED solutions in just the past 12 months and more than double that since i started testing 4 years ago, im pretty confident in my opinions of them and their performance. I have only managed to get 2 of all the units tested to last more than their rated 30,000 hours, both were Philips, and both were expensive. Not one single LED i have tested had satisfactory dimming capability. They also all ran quite warm, had poor colour rendition, and despite being very bright on paper, were not capable of lighting the room evenly due to a number of factors.
I too would like to know how Onkel plans to carry such a heavy object onto a plane, but more so, how he plans to lift it over his head to store it in the overhead compartments!!

So far the one in my track light hasn't failed but I have had a few of the others fail within the stores return policy(thank goodness) but lately haven't had any to fail
But the led bulb is getting better or gm wouldn't use them as headlights on the Cadillac escalade suv(can be got with either hid or led headlights I prefer the hid due to brightness and color rendering most I have seen seems dim and yellow(maybe I am just being picky ))
