Live video to overhead

I’m sure the brain-trust here has an easy and relatively inexpensive way to get a live video camera feed to an overhead projector for our fly tying classes.
At a fly fishing show we were told the system they use goes for about 8 grand. Way too rich for our non-profit blood!
Best Buy told me it is near impossible to do. I find this hard to believe or an opportunity for the inventive types.
My first thought is to use the webcam on my laptop but I have concerns of frame delay, focal area and field of view.
A videa camera seems to be more flexible in use and seamless as far as frame lag.
We hold classes at a Gander Mountain which has a room with a big screen and overhead projector. Our guest speakers have no problem using this system through their laptops to show their power points and slide shows.
I just need a smooth way to feed live video to it.
‘Lil help?
Thanks.Jack,
As a lecturer and one who travels extensively for various venues, I can tell you I’ve seen it all.
I tied and gave a PowerPoint presentation at the club meeting for the Upper Snake River Fly Fishers in Rexburg, ID two weeks ago and they had just purchased a cool little camera that they hooked up to the laptop and then sent it through the system at the Library where we were meeting. The live feed was next to perfect and the projected image on the wall was very clear and made it possible for all in attendance to view from the cheap seats!
Hi
A few years back I gave a fly tying demo in the context of a trade/fly fishing seminar show
We used a Canon ZR vid cam trained on the vise and that was ported out via a S- vid cable to the digital projector . As I remember things it went very well – no jittery vid and a decent/good/very readable
They used to make LCD panels to fit on top of an overhead projector. Here’s an example that claims to meet the VGA specification, but it might be too old (slow response time/low resolution) to be effective for displaying video.
Am I ever glad Neil didn’t have the final answer!
Kelly, did you use the camera for showing your tying and if so was the depth of field?
I’m just a tad concerned being that it states that it is a document camera with possibly a DOF too narrow for tying by focusing on just a thin slice of fly!Thanks
Maybe I’m missing something, but I assume you’re talking about a regular digital projector and not the old-fashioned transparency projector?
You’re right Curtis, I read too quickly and saw that he wanted to display video on an “overhead projector” and I instantly assume he’s talking about the old fashioned kind, when what he was really concerned about was latency and camera quality.

Jack, the DOF was perfect for fly tying applications. Like I said, they set it up for the first time and we were under way in a matter of minutes. Excellent pic quality as projected through the overhead projector the library provided. Very, very simple as compared to some of the answers you’ve received. I was impressed enough that I’m buying one to showcase my own tying for presentations and such when I’m on the road.
Sometimes just a simple solution may be the best option…
Kelly.
The IPEVO did the trick!
As was stated, it was pretty much plug-n-play. Load the cd, plug in the USB cable and away she went.
Tonight at our club meeting I set the camera up last-minute as our speaker was sorting through his tying material.
Everything came through, not production quality, but certainly well enough considering the low price of the camera and the lack of set up headaches.
Thanks for the tip, Kelly and everyone else who answered.
