Progress update

I have finally been paid this month and first step is to buy the new PC. I have decided to use my current PC (P4, 3.6GHz with nVidia 7800 GTX) for the SimRoom and get a new machine for other use. I will be getting the Intel Quad Core 6600 as soon as they release it with proper stepping technology to preserve some voltage and heat (should I decide to overclock it).

Air Motion Seat

A friend of mine found this article on TechEBlog about the Air Motion Seat that looks like a nifty invention. I've also embedded the video below:



I haven't found any details on pricing about this one yet, but it will probably not fit within my budget I'm sure :)

DIY H-Shifter

The H-Shifter that I have put on my shopping list will set me back 2270 SEK and in an attempt to reallocate some funds in my budget I am looking at some DIY H-Shifter projects on the net to see if this is something I should also attempt.

It seems like some handy work along with a cheap USB GamePad and the ALShift utility by Act-Labs would go quite far in putting your own shifter together.

I've found some web-pages where people have posted their H-shifters and it will be useful for knowledge, tips and tricks and inspiration:
H-Shifter Project - 8 gears with modification plates for 4+R, 5+R and 6+R plus Sequential Mod
H-Shitfer Project - 6 gear project
Project Web H-Shifer - 6+R project

While looking at these DIY projects I also realised that I haven't really considered the Act-Labs products before. They have a H-shifter that costs $106USD which is a lot cheaper than the one from FrexGP. It comes with 4 extra shifter-plates:

2.35:1 Ratio Anamorphic Lens

Being a bit odd, I was dreaming about the SimRoom last night and I thought it would be interesting to have an even wider screen as in racing sims it's quite important to see what is happening on the sides rather than what is going on above your car or under the bonnet/hood (leave that to the virtual mechanics!). As far as I know there aren't many manufacturers of projectors capable of displaying 2.35:1 ratio screens so I had a look for lenses and there seem to be quiet a few lenses on the market for this purpose. Amongst others I came across Prismasonic and their cheapest lens for this purpose is the H400-series and it will do just this for you. They also have a calculator on their site that allows you to have a look how the lens will adjust projected image dimensions for a number of projectors.

So far, both the calculators I've found for optional lens and for calculating throw distance and screens sizes have the Sanyo PLV-Z5 which is supporting my case of buying that particular projector. It would probably have been nice to increase the resolution to a 1920x1080 projector - but they cost a lot more than 1280x720 projectors and hopefully the latter resolution is sufficient for this project.

The cheapest Prismasonic lens still costs over 5000 SEK so again, this will be beyond my budget and it is probably aimed at the home cinema boys that also spend more on speaker cables alone than I have allocated for this entire project :)

Curved Screen - Additional Thoughts

I am literally bending my mind around the idea of bending or curving my projector screen. If you look at how an image is projected it is actually pincushioned which means that if the screen is flat, it would be distorted slightly towards the sides of the screen. This is because the light has to travel further in order to reach the side of the screen in comparison to the middle.

I used Projector Calculator Pro to calculate throw distance and screen sizes, an excellent tool for saving time when playing with distances, zooming and different models of projectors.

The Sanyo PLV-Z5 projector is capable of displaying a 90" screen at a throw distance of 2.7 meters. It is also capable of lens-shifting the image so you can place the projector up to half of the height of the screen above the top end of the screen. By bending the screen making the distance 2.7 meters to all areas of the screen, and by placing the screen 1.5 meters in front of the driver position, my calculations (that may very well be wrong) tells me that I'll get a representation field of view of 70.3 degrees. The naked human eye has a field of view around 160 degrees, but most of the peripheral field can probably be disregarded here.

Below is an illustration of my ideas in a visual form (click to enlarge)

If I instead move the driver seat forward to 1 meter from the screen, the field of view increases to nearly 94 degrees - but I need to test how being so close to the screen will affect things such as image quality and motion sickness etc.

Live for Speed with with FOV set to 94 degrees (click to enlarge)

As you can see above, the image dimensions and proportions are the same in the two screenshots, but the second image with FOV at 94 degrees contains more visual information on the sides. I will soon post another note on the blog that discusses FOV and how it affects distortion, perception of speed and so forth. But now it is 4:43am so I'm signing off :)

SimRoom Shopping List established.

I have spent more time reviewing the hardware and come up with the following shopping list for my SimRoom project.

The list also excludes the simulation computer (it will be a dual core Intel machine with a nVidia 8800GTS/GTX graphics card - I also have most of these parts already) as well as decorative stuff, cables, mini-fridge and sound proofing material :) I hope shipping isn't too expensive because it only leaves around 11'000 of my budget minus shipping charges. But, hey, I am sure I can convince wife that decorative design of the room shouldn't be part of that budget as it is in her best interest that it looks nice as she walks past the room!

Samsung 52" LCD

I was in an electronics shop here in Sweden yesterday and as I reached the TV-section of the shop I saw something so beautiful that I nearly went into shock. After a few moments I wiped the little tear out of my right I and realized that I was witnessing the Samsung LE37M87BD 52" LCD TV!

This amazing creation is the best TV I have ever seen so far, and these words are coming out of the mouth (and into the blog) by someone who is a sworn plasma-lover when it comes to TVs. I currently have a 42" Samsung Plasma (1024x768) since a couple of years back and was aiming for the 50" Pioneer HD Plasma (1920x1080) - but it cost a whopping 50'000 SEK so I haven't got it yet, the cost being the one and only reason. Now, however, I am pleased I didn't buy that plasma because this 52" LCD has something new - namely ClearView! This eliminates the single most problem that I've never liked LCD-TVs before - the backlight! I am not sure if I am using the term backlight properly, but what I am refering to is the gray shiny areas of a traditional LCD screen you get around the edges when the display is show dark images. With ClearView you get a slight increase of reflectiveness of the display - but in return you get pitch black when it's supposed to be black and contrast is great. I might add that I had the opportunity in the shop to see this TV next to a Pioneer 1024x768 plasma, a samsung 1024x768 plasma and a Sharp 46" LCD (without ClearView) - and in my opinion the overall image quality was best in the ClearView LCDs, then the plasmas and finally the Sharp LCD coming in last.

This TV has changed my view in the Plasma vs. LCD battle, and not only does it look huge and amazingly great - it has 3 HDMI inputs (finally!) and it supports 1080p - true HD-resolution.

I won't be getting this TV for my SimRoom - but this fabulous creation had to be mentioned here if anyone is in the hunt for a great display for a simulator room with a higher budget than mine. It costs around 30'000 SEK by the way - a very fair price I might add. You can get it in the sizes 37", 40", 46" and 52". Run out and buy one now :)
