Well, after such a long time lurking, I've finally decided to get started on a projector.

This projector will be more of a learning kind of thing, you know, to get me ready for a 15" project.

Anyway, since I've already gotten started a while ago, I'm going to state what I've done so far.

Soooo here we go


A while ago, I build a portable TV (well, only AV input). Pretty easy rewiring and stuff, but I (really) suck at building things, so it looked like crud.

I used the Hip Gear PS2 controller screen:

Luckly got it for $20 years ago at futureshop. Sadly it's now impossible to find.

Taking it apart, I took the LCD out and removed the backlight.

On the front of the screen is a layer of anti-glare.

After 4 hours of soaking, I was able to remove it with no problems, and now allowed much more light in.

Then I noticed there was another layer on the other side, so I attempted to remove that side's anti-glare as well.

WELL, bad news was that I got impatient and only waited 2 hours this time. I had some trouble taking the anti-glare off this time and only got half off, and needed to try prying it off from the otherside, but since I couldn't get a good prying angle, I had to take the screen of its casing (which it was glued to) and I ended up cracking the thing.

Poof, vamoose lost a screen. The sad thing is, turns out there wasn't much of a difference between the side with both AG off and the side with only one AG off!

Now I'm in the process of finding a replacement one.

Here's the PSU enclosure that I'll be using:

And the fan + heatsink I'll be using to keep my led lighting cool:

And finally the lighting I'll be using:

It's 20W and 800 lumens, but I'm thinking of buying a 1000 lumens one off ebay.

I decided to use the fan from the PSU rather than the one from the heatsink. In order to get things to fit, I had to cut off the clips on the edges of the heatsink.

In order to get everything to fit, I had to attach the fan to the outside of the PSU rather than the inside.

I'll cut off those ends of the screws later.

Here's a model made from cardboard of what I'm gonna do (partly)

Finally here's how I'd like things to work:

But problems/questions I'm having are

- finding fresnel lens with the focal lengths I need
- do I need to use a cold mirror? or would that be a hot mirror?
- do I need another fan?
- do I need a UV Filter?
- I most definitely can't use a camera lens can I?
- AC conversion

Since I need
- a new screen
- fresnel lens
- projector lens
- LED

before I can go any further, this project will probably be on hold of a month. See you guys then!

Another question.

For my design, would it be better to get an LED with a Viewing Angle of 140 degrees, or 160 degrees?

Since the first fresnel lens is very close to the LED, I'm thinking a larger angle one would be better?

So how are things going? I have started a OHP build but my time is limited so things are going slow

This is an interesting project. You will need a front side mirror, so that the image is clear and ghost free. I you will need two Fresnel lens and collimating and a focusing. I don't know if you will have enough distance though. You cannot use a camera lens, you should try to find a projection triplet or maby even a rptv trip. I have a standard lumenlab triplet if you are interested for 10 bucks. Good luck with your project.
