My Next Project

[Barry_White]

My 20" GE (15 years old) just stopped powering up today and I ran into this thread.

I keep my 19"and 21" crt monitors around for watching dvd movies thru my PCs.

The crt movie quality compared to the lcd is so excellent its scary.

I love my command post of 4 19" LCDs on a single computer that I use to run various business ventures from my home office.

The footprint of 4 lcds compared to the footprint of the crt is rediculous.

Is the key to this project the "pass thru" light projecting from behind the lcd screen?

Specifically, has anyone, or could I, use my 21" crt to project from?

The thought being the starting quality would be so much better.

Hi Barry

As you say; Is the key to this project the "pass thru" light projecting from behind the lcd screen? Yes.

Specifically, has anyone, or could I, use my 21" crt to project from? No

There is on the net some where some one who has built a box to magnify a normal TV or CRT screen but the result is absolute crap.

The basis of the projector is to look for high quality LCD computer screens especially one with quick refresh rates as this makes watching fast moving pictures easy to watch.

The results are ideal watching of movies and TV and as I may have said before the quality out of the projector project is equivelant to a $7000 to $8000 commercial projector.

Hi Barry
After coming across this thread by chance and being in the process of doing a home extension, I must say after the last few days reading this thread and your projector project, I am Hooked on the idea so much I am now sidetracked I making my own projector. To fit some where in the new extension. Or should I say built the extension around the projector.

I have joined up to Lumenlab and they have certainly got a lot of information.

So Im busy planning my projector. and working on sourcing the parts on the cheap if avaliable.

I would like to ask you did you get your frensels + lense from Lumenlab and if so did it take long to arrive?

Cheers John

p.s. I will be back with some pictures when I get underway.

I have been a member of LL for quite some time now and i built my projector. search "swiftden" there . I am now building a HAAS style projector.

Not tryin gto sound rud eor anything but what you build and how its built is ment to stay within the paying community of that forum . that is how it survives.

Happy building and keep that in mind when you pass on info from the plans etc .

So how is the word meant to be spread on LL if someone like Barry dosn't rave about it to joes like us which will encourage us to fork out our hard earned to join in the fun at LL? If Barry wasn't as detailed as he was on here, I certainly wouldn't have forked out!

Hi Allan

As Shane Watson said how would other people know about building projectors if others weren't made aware of the Lumen Lab forum. If you have a look, at no time did I post the instructions that I purchased from LumenLab all that I did was show what I did with mine.

The people that are part of this forum would have higher skills to produce excellent projectors far better than 75% of the members of the Lumen Lab forum and if they posted them on Lumen Lab they would be an inspiration to many of the members of Lumen Lab.

How do you think I found about Lumen Lab because if I hadn't found it I would have ended up buying a commercial projector and would not have got the satisfaction of building it. My grandson told me about Lumen Lab and that is how most people find out about it is by word of mouth or "Word of Internet".

I would consider that I would have been inspirational of getting 3 or 4 of the members of Ubeaut forums to build one. So those people would have purchased the plans and the lenses and perhaps the ballasts from Lumen Lab and I don't remember getting a cheque for commission from Lumen Lab for the sales.

And who knows how many guests on this forum have seen the post and gone to the Lumen Lab forum to build projectors.

If you have a look through all the posts on "My Project" at all times I have directed any one who has inquired to go to Lumen Lab and buy the guide to find out how to build one.

I don't usually let things get up my nose and have a pretty thick skin and if I am in the wrong I will take the heat but I consider you are out of line here and your apology will be gratefully accepted when it is forthcoming.

BTW I joined the Lumen Lab probably the same month as you.

Added Comments after reading the above two posts.
And as you can see there are two members in the two posts above that have joined Lumen Lab so perhaps you should tell them to send me my commission.

Hi John

I did purchase my fresnels and lenses from LL and they took 6 days to be delivered to my door and I live 55klms from the nearest major town out in the bush.

If you search through the Australian Members Forum on LL there is a member who's acting as an agent for LL and I think he is in Sydney. If you can't find him post a message and I will have search for you.

Maybe because Swiftden seems to know so much maybe he can tell you.

Hi Barry
I have ordered my lenses and a new pro reflector from LL hope to see them in 6 days and Ill be wrapped.

Cheers

After Ive been browsing through the forums on LL for the last few days I did find in the Lumenlab news thread on page 3 some interesting reading about how the guide for the 15 inch box is now avaliable free to the general public because they what more ppl to be interested in it?

I'll remember that if you ask for free advice on THIS forum.

My wife and I were speaking of projectors yesterday, and I was enthusiastic about LL based SOLELY on Barry's post, and the follow-up thread.

I will pay the fee for the plans and the forum-its close to the price of a foreign wood working magazine, so good value. I think that an apology to Barry would be nice.

Like Greg above, I have also discussed this with my wife and it is a project for later this year perhaps. I would not have known about it unless Barry had placed it here. There is insufficient information to just copy what he has posted. I will also pay for the plans if I go ahead with it. If someone does copy it, and lets assume someone does, LL would seem to still be out in front.

I haven't browsed through Lumen Lab for a while and I was just browsing through that link you posted above and looked at the results from the new Pro Lenses. Like the owner of Lumen Lab "Brain" says the results of the new lenses is "Freakin Awsome". If anyone wants to look at the results of a good projector it's on page three of the post.

I may have to think about building a projector with the pro lense kit and sell my first projector.

[Tankstand]

And a huge thank you to Barry for pricking my ears up!

If you go to the above link and go to page three, have a read of post#43!

Here's the link to the "open source" basic guide! Here

[John99]

Hi Barry
Yeh I think the new Pro lenses are awsome to but for my first box I`ll stick to the triplet lense, but after having done helps more reseach into the project I`m already planning my second one!
Using a folded design to see how many folds i can put in it and how small I can go.

Cheers John

[Barry_White]

Seeing that so many seem to be interested in this project I am happy to offer any assistance to anyone that is going to build a projector.

Although there is excellent help on the forum there are a few issues here in Australia that have to be overcome. I had a look at the current guide and even that has been improved since I purchased it.

I believe because this forum is made up of woodworkers and potential woodworkers some excellent projector cases will be made. By going through the LumenLab forum there are some excellent designs posted there and as they say the greatest form of flattery is to copy some one else and improve on it as you go.

You have to bear in mind dollar figures quoted are $US and vary a bit in Australia.

hello barry, im madmarvin and im a newbie, i wish i had good woodworking skills, your projector box is excellent, i think i will do a lot of reading here and get some tips on joining timber, im in the process of making my own projector and i just bought my 250 watt light and ballast yesterday, unfortunately the salespeople would not give me a hint on how to wire everything together, (to cover themselves they told me to get an electrician) i have searched on the net for most of the day when i came across a reference to your project on this site, i read your wiring diagrams and i think i now have an understanding of what needs to be done, but i was wondering if you could confirm some things for me ????



in this photo you will see that i have painted in an arrow pointing to a white square, in that square you will see 2 connections with 2 screws each, judging by the diagram on the actual ballast, am i right in thinking that i have one live wire going into the connection on the left, and then have an outcoming wire on the right ???
(does this mean that although there are 3 wires coming directly from the wall socket, that only one wire [the live one] will be utilised through the actual ballast, and the neutral wire will connect to both the ignitor and the lamp itself, )..........



in this photo of the ignitor i see that the "outcoming" wire from the ballast connects to both the ignitor and lamp, because i dont understand how ignitors work, to me it just looks like the ignotor is bypassed............

also, which colour wire is the "live wire" ??? i saw in your diagram that the "L" live wire was green, but i thought green was the "earth" or ground, is the earth wire actually the "neutral wire ??? ........ plus, on my capacitor, i have two wires one is blue and the other is a brown wire, which one is connected to the "live wire" ???

i hope you dont mind me asking too many questions at once.........

i have read a bit from lumenlabs, but i have not joined them, i read a lot of information from another site called diyprojectors i also look at diyaudio forums where they have a projector section, and just for a bit of added info, if anyone needs to get FFC extensions, you can find them online here in australia at farnellinone this link actually shows the extension that i am now waiting on..........

i noticed in an earlier post that someone asked how big the lcd's are in the commercial projectors, apparently they are only 1 inch big, i know that because i was told it by people from "diyprojectors" i had bought an lcd projection lens on ebay that had come from a sony commercial projector, and asked them how good it would be, pity i didnt ask them before i had bought it.......

anyway, any info would be greatly appreciated, hopefully i will be watching 7 foot wide movies tomorrow night.........(with just a bit of the lcd electronic board in the way, till i get the FFC extension that is)
