Re: [Olpc-Haiti] Need in Haiti: inexpensive portable projectors forOLPC/XO classrooms
I have not seen the XO, but I think we should be rather thinking about these new cheap netbooks for these other tasks and use the XO for what it is designed. I am now evaluating a netbook I bought on Ebay for $79 and another that is priced at $139 on Ebay. These types of machines can be configured for Administrative use and to do these other things.

Aside from this wonderful home-made prototype, that unfortunately overheats, what's achievable? http://blog.laptop.org/2008/11/16/hardware-hacking-first-pass-at-an-xo-projector/ Is the following (control/display your XO-computer from a non-XO PC or Mac or Linux box) the most viable approach? http://wiki.laptop.org/go/Remote_display Could hacking an on-board VGA port realistic for XO-1's (to an external VGA monitor or projector) be made into something more than a gimmick -- with broad(er) classroom potential? Even if presumably impossible with upcoming XO-1.5 laptops? What software approaches preferred Sugar Activities make kids/teachers project presentations shine?

Agreed. There's a new breed of extremely miniature projectors which might be well-suited, for example: http://www.google.com/search?q=miniature+projector http://blog.laptopmag.com/mini-projector-face-off-3m-mpro110-vs-dell-m109s These are priced at about 1.5x the cost of an XO, and combined with the VGA output from a schoolserver, would probably make excellent accessories for a classroom. There's no real need to use the new ultra-mini projectors in most classroom situations, something like http://www.amazon.com/Torpedo-Entertainment-Game-Projector-BLACK/dp/B0033M5NXQ/ might work as well. Note that the primary expense for a projector is likely to be replacement bulbs. I also wonder if http://www.amazon.com/Porta-Trace-Mini-Sketch-5x-Opaque-Projector/dp/B000A3E2T2 might work, if just placed on an XO screen. There might still be heat issues, but it's cheap enough that an experiment might be warranted. --scott -- ( http://cscott.net/ ) ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Needs to be larger though - the XO's screen is 6.0x4.5 inches, and this one only sees 3.5x3.5. The middle one (5x5) is still to small, the big one (7x7) would fit but is already close to the XO's price itself. Worth a try though ... http://www.gagneinc.com/PortaTraceTrace-master.html - Bert - ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
