OK -jumping into this.
I have been reading and I "think" I have the #'s down. But I would appreciate if somebody can look them over.
I am going to start simple with a 15in HDTV that is a very easy to remove. But I plan on grabbing from the local flea-market any 15in LCD to "play with". I ultimately want to do a ceiling mounted Haas design, but will start with your basic box to get the measurements down.
Here are the parts I am about to order….
Element 15.4" FLX-1510 LCD TV
S15 Projection Lens Triplet 320mm
220mm Fresnel
317mm Fresnel
LL/Vue 400w eBallast
65K T15 Bulb
The room I have is not very large –the screen I plan on projectring to is only 5ft wide. My brother who is very good at woodworking will have different dimensions. He’s interested on making one so we will do them together. So we plan on your basic box then refine the measurements and go for a Haas design with the ballast outside.
The figures I got from FocalCalc are
LCD 15.40 mm
Fresnel Gap 25.40 mm
Fresnel FL 317.00 mm
LCD Distance 392.19 mm
Triplet FL 320.00 mm
Screen Distance 5.57 in
Screen Size 72.00 in
So before I start burning a hole in my credit card……let me know if I’m goofing up somewhere.
Thanks in advance
