Hey Builder I just ordered a 250w HQI ballest light and endcaps from www.yellertwoproducts.com and it came within 3 days and was packaged really well I would recomend them. it was 159.00 plus shipping, hope that helps.

i will...

as soon as i find the time to take this apart... with pictures hopefully...

$159.99 is way too much for a lightsource that will be installed in a DIY projector, is it not?

i am watching a few ballasts on ebay and i am not planning to pay more than 60 for both ballast and the bulb. SO far i got a 250W MH bulb for $20 from ebay, brand new, 22000 lumens, 4200K. so that leaves me with $40 for ballast.

good luck all

Slize,

Yes, please let me know how that NEC 1525 comes apart.

Guys, I would REALY appreciate some help here. I tried using a Samsung Syncmaster 15" AND a NEC 1555v also 15" and they both had a dang ribbon cable conecting two cards behind the freaking screen I cannot use either one as it covers up too much of the screen. btw the Samsung is a bad **** lil monitor (the best screen I have seen, as far as all of it goes). But please help me on this (as I am driving myself mad, lol) and let me know of any type of LCD monitor displays you guys have used (that were easy to work with once taken apart and are still for sale, stores or e-bay) I would very much appreciate it. Thanx to all in advance.

I don't know anyone in Ohio that uses the word "****".

I have had great success with the NEC 1545V. What is the LG model number on the internal TFT module on the 1555V?

Mav,

Dunno. My friend is the one doing it (I bought the stuff and I am doing most of the research, but I have never used soder for anything) yes, I use "****" all the time, lol. btw, I can't find a NEC 1545 for sell anywhere (even ebay) do you know of any others for sure that work?

Hello all.

Just stumbled into this forum and thread a few days back.

Interesting ideas here. This subject has been of interest to me, on and off...for some time now...but I must admit...I haven't yet tried to build my own, due to excessive cost.

Anyway.....

After reading most of the individual postings here, I thought I'd add my two pennies worth.

Some info and items readers here might find of interest:

Scientific Americian Magazine, March 1991, vol 264, #3
page 76 "Non-Imaging Optics - Funnels for Light can concentrate solar energy to supersolar intensity"

The principals might help with light collecting problems I see mentioned here...


Scientific Americian, "Amateur Telescope Making, vols 1, 2, & 3", Albert G Ingall Editor
- it's not just about telescope making...good optics info, theory and DIY how-tos -- no ISBN number


and finally...

IBM made a Thinkpad laptop, models 755CV & 755CDV.

These particular models are designed to be used as normal laptops, but also can fold open flat, after removing the LCD panel back cover...for use in an OHP.
Downside...640x480 pxls...low colour palatte...and 486/Pentium classic (upgrades) CPUs. Obsolete.


Hope this info proves useful.
