Well after my first 2 projectors failed, well the 2nd works but lcd broke, then i fixed it and didnt want to put it back in projector.

So time for the 15" route :smash:

Please bare with the text as i post on many forums and tend to just copy it across :) lol

So then I will start with fan controllers, everyone must have seen the zalman fan mate, with its vairable controller. I have brought the components to make 5 of these to control the fans.

The fans i have now (dont know if i will be using them all):

4x 120mm ebuyer fans
8x 92mm ebuyer fans
5x 80mm ebuyer fans

Should be enouth to cool my projector nice and quietly

Theres around £15 worth of fans there i would say.

I won some thin aluminium off ebay for £20.50 delivered which will be used to line the wood around the light up to the rear fresnel lens, this will all be sprayed black which is heatproof (more on this when i get round to it)

As for the general presentation of my projector I plan on celing mounting it and painting it white so it blends (yea right) into the celing, so i ordered 6x drop down lights (the ones that fit into celing) to mount 2 or 4 on the diagnal sides of the projector and maybe 2 or 4 over seating
So I am going to have a nice home cinema

I want a 4:3 LCD 15" so i have been thinking of the benq fp567 v2 which quin used and the results are very impressive and 16ms refresh which will be good for gaming and xbox etc
Seen the LCD for £100 on ebay so I might go for that but nothing on that is 100% yet

Ordered some fresnel lenss from www.lumenlab.com and they cost £35
I already have there object lens so that saves me $30 or what ever it is on there site

I will be using my 400w bulb as its nice and bright

Now the ballast (transformer type thing) generates alot of heat and is quite noisy, i dont want to splash out on a electronic one so i need some ideas, what about mounting it on rubber? for heat i will make some kind of heatsink with the aluminium i have ordered

Need options on the noise of the ballast as its quite anoying, not very loud but noticable./

Now to find a lcd, order wood, yes wood cant aford 100% alu, and brackets and paint then i think i have everything but a kvm switch

Next day:

Well another day has passed and I couldnt let it go by without spending some money. So today I have ordered some stuff which should be useful

3x Flat aluminium 20mm x 1.5mm x 1m - £9.45
4x 5mm Threaded Rod 1m - £3.92
A bag of 100 5mm hax nuts for the threaded rod, but i already had 100 of the bolts so now i have 200! Dont think they will be used somehow - £1.92
8x Right angled brackets for holding the wooden frame together, i almost decided on a aluminium frame but that would have been another £20 - £3.84
2x Aluminium vents - £7.96 :| would have got maybe 2 more but at that price I didnt want to.

So thats around £27 spent.

I also ordered a dremel off ebay for £13.50 + £8 pp hope its good as i need to cut the fresnels down to the right size.

NExt:

My Maplin order came through today:

1x AC Euro Plug
1x Lead free solder
5x Min pot Lin 1k
10x MF Risistor 680
10x 2 way vertical t block
5x 7805 transistor
1x red rocker for light
1x normal for all power

I ordered some 15pin plugs thinking they were vga type ones, but there standard 15 pin plugs! so i have to order some more now Need to order some knobs anyway for the fresnel adjustment so no worries

[IMGHTTPDEAD]http://www.x1desk.com/images/15pj/2_elec.jpg[/IMGHTTPDEAD]

Fan controller finished without heatsinks (will add them when i get the metal)

[IMGHTTPDEAD]http://www.x1desk.com/images/15pj/3_control.jpg[/IMGHTTPDEAD]

Now i have got this far, i need lcd, wood, paint

My plan is to make a IR remote to turn the projector on off and control the lcd but this will take some time

More on this later :)

Loki047: I have my light box built already as i am using the one from my last projector, and to mount it i put 4 bolts through the back panel of the wood, if i want to adjust it i have to turn it off, move the bolts and tighten them not the best way but i cant think of a other way


ancorp: Thanks :) should be some updates later
 
Another update:

LCD Frame with no supports just the threaded rod for adjusting it

[IMGDEAD]http://www.x1desk.com/images/15pj/39_lcdf.jpg[/IMGDEAD]

The back of the box (not i have only sprayed the metal and some of the frame work the mdf is still in progress thats why its white ;)

[IMGDEAD]http://www.x1desk.com/images/15pj/40_back.jpg[/IMGDEAD]

As i had a problem with the original front fresnel mount i had to extend the existing one's

[IMGDEAD]http://www.x1desk.com/images/15pj/41_fres.jpg[/IMGDEAD]

In place and its out! and it overlaps so this needs work still

[IMGDEAD]http://www.x1desk.com/images/15pj/42_place.jpg[/IMGDEAD]

:smash:

I am researching into making a ir decoder for the projector so i can turn it on off etc and control the lcd :D
