I had thought about going the overhead-projector route...until I found this
site:
http://www.lumenlab.com/
(I'm not affiliated with this site, just a paying customer)

It's $20 for the guide, but that also gets you into the protected forums
which is more than worth the price
for all the info contained in there.  You can check out the un-protected
"project gallery" forum without purchasing
to take a look at what some of the members have been building.

The overhead projector design seems to me more of a short-term solution
(held together with packing tape?)
While the Lumenlab design is meant to be a bit more sturdy in it's
construction.
I guess it depends on how much time you want to put into it and what you'll
be using it for.
Don't get me wrong...the overhead-projector will work, but for how long?
Bend one of those FFC edge connectors on the
LCD (that they've got taped in place) too far and that panel is done for.

Check out both sites if anyone's interested in the subject.:-)

(Just for the record, I haven't had the time/cash to build either one
yet...I guess you could say I'm in the
pre-pre-design phase.)

(RVC)  I'm about to go outside and fix the rear brakes on my Vanagon.  This
is one DIY project that needs to
be finished sooner-than-later.

'till later...

display screen - $300

This is a do-it-yourself project that caught my attention. Thought there
might be some list members that might be interested as well.
There is a free how-to  video that can be down loaded.
