sorry about this late question and how noob it is but what's the psu box do and is it just made out of cardboard? sorry if it's obvious or it's already been asked but I had to ask.

hehehe i believe im making a projector and not a jiffy fire lighter lol, ok sorry just a quick joke, the psu box is like a power supply in a comp, it breaks down the the power from the wall to be able to be used for the lcd, ballast and fans, there are 2 power supplies in this psu box, 1 is for the lcd and the mods, the other is for the fans and for another modd that im thinking in doing, that extra modd is a small circut to power a electronic screen that will go up and down when i turn the projector on and off via the remote, the other thing in the psu box is the ignightor and capacitor, also the main power relay, the box is also made out of aluminium wich is strong and wont burst into flames unlike cardboard lol, ill have more pics of it up soon, im missing a power unit that needs to go inside as the postal system right now is very slow, also i still dont have my frensels or my mylar! but the psu box is nearly done.

Merry Christmas

did you absolutely had to solder anything to make the lcd free so light can shine through, or is that something you just wanted to do?

hmm not sure what u mean but the only thing i solderd is wires lol the light will go through the lcd after u modd the white plastic backing on the lcd, u cut that out with a trimming knife ( removed from lcd ofcourse)

trev, i think he means did you have to fix any ribbon cables or ground any wires after taking the thing apart...

Heya verbose, hope u had a great christmas buddy, ok for all of those who want to know if there are any cables to lengthen on the lilliput lcd, there are none to lengthen, there is a small card that is atached to the lcd that gets folded out at a right angle and thats it, u also dont need to ground anything, the modds i did was for my own purpose and to also take away the front buttons pcb as its a pain and not realy of any use being in a projector.

Since a few weeks I am following this forum and a few others. I am still learing whats important in a projector. I like to make one myself but I don't know what to choose. I have seen you have chosen the Lilliput 7" screen.

- Now my question is, could you send me a picture of a projection with the Lilliput? So I could see if its a good screen...
(you can send a pic to adrianvanourti@hotmail.com) :angel:

- I have read that a small screen (7") cannot have a large projection with good quality. Is that true?


Good you luck with this nice design!

i think retail projectors answer that for you, the lcd's in retail projectors are 1.3inch, there is more then just to go on size, there is resolution, screen door size and contrast, as for a pic of my projected image, well my projector isnt finnished yet thanks to the $%&^%$#@$^% postman being on holidays lol but i have projected it in a testing phase, its about 2-3x clearer then my tv at a projected size of 140inches, a couple of posts back i have said that my cam is broken and wont take a screen shot, im still trying to figure out why but even if i take a shot of just the light bulb when on it wont take it properly so im thinking its not the cam but the frequency that the light is operating at, so maybe there is a conflict with my cam and light, ill try to borrow a cam soon or try out my web cam, at the moment im more worried about getting it finnished before next christmas comes.

lol thanks guys for the explanation, some of those explanations are quite funny, ok not much to update u guys with because of the postal system down here and im waiting on parts so i thought id take a few pics of the psu box and how its comming along. In these pics it may look a little rough as some of its just sitting together and its not totally finnished, ( ie the lid just sitting on, and ac wirers not cable tied into position). In this first angle u can see the wires coming out, the 2 white colour are for the lamp, the black is for the lcd power and the red with thge white plug is for the relay pulse that pluggs into the lcd, this isnt all of the wires, i have another 6 -7 to come out of there yet. This psu box wasnt that easy to make, having that said ill still put it in the plans, if your going to use different gear from mine, make sure u change sizes to acomodate your gear and not mine on the plan! that will be the only problem with the plans but u will have the layout, plan and guide to build your own so it wont be too much of a problem.

ok here is pic 2, this is more of a frontal angle, the fan will go to the side of the outer side wall while the power pug and fuse to the back. Those 2 blue wires are just poking out of the fan to get them out of the way for now, they dont go there for obvious reasons.

ok and here is an underside shot, i have rubber feet on the bottom of everything including the lcd unit, this is to help decrease noise from fans, heat on the plexi, and to help aid cooling, also for looks, through each feet there will be a screw that will screw into the plexi holding each unit down.

ok and here is an inside shot, it is very compact inside this unit, i didnt waste any space for anything, but its also placed at a safe distance from each other, ive also double insulated all solder joins with 2 layers of heat shrink and insulated the underside of pcb's with some 1.5mm plexi i had laying around, there are 10 mains wires in there, 2 go to the main power relay being the input power while 8 come from the relay powering all of the gear, u can see the relay if u look closly, its to the far right, then next to that there is the first psu for the lcd, that is a standby power psu wich means its on all of the time, next to that will be the ignightor and cap unit, and then to the front center there will be another psu that will power the fans, other then the 10 mians wires in there, there will be 3 from the ballast, 2 for the lamp, 3 sets of fan power wires, a power wire for the lcd and then the relay power wire, as u know some of those are already in there. This power supply box will draw a total of 180watts, thus being the projectors total power draw at full load, and the psu unit will weigh in at about 1kg.
