Q. I am planning to solve math problems on a piece of paper, record it and post it to the web for my students to view. What kind of camera should I buy?
A. It would cost in excess of $3500 to get a HD camcorder that could equal the video Quality of a $300 MiniDV tape camcorder.
Consumer level HD camcorders have 3 problems. 1) Blurry, fuzzy, out of focus areas closely around people in videos taken by consumer level HD camcorders. 2) Any movement, even a wave or lifting an arm, while in front of a recording consumer level HD camcorder, results in screen ghosts and artifacts being left on the video track, following the movement. Makes for bad video, sports videos are unwatchable. 3) Mandatory maximum record times - 1 hour, 30 minutes, 8 minutes, 3 minutes - all times advertised as maximum record time for some consumer level HD camcorders. No event i have aver been to is that short. Either take multiple camcorders or pack up with out getting the end of the event on video.
With a MiniDV tape camcorder, record 60 or 90 minutes ( camcorder settings), 90 second or less to change a tape and record for 60 or 90 more and repeat till you run out of tapes.
You can get a Canon ZR960 for $250. It is a MiniDV tape camcorder, has a Mic jack. You need a firewire (IEEE1394) card ($25 to 30) for the computer and a firewire cable (less than 10) to be able to transfer video to your computer.

Flip camera: will it video record my lecture if I use a double board?
Q. How wide of a space can it capture? Will I have to manually move it when I switch from one board to the other?
A. Most likely yes. the best thing to do is get a wide angle lense to get the best coverage, and this will also allow you to get the camera as close to you as possible to pick up the sound better. Not many Flips have the wide angle option but the one I put in the resource box does have a wide angle lense available and its not expensive at all.

What is a cheapest microphone attachment that I can buy from Amazon that will allow me to record lectures?
Q. I need one that can attach via 3.5 mm jack to a digital voice recorder
A. Try looking for a video camera shotgun mic. They usually have a 3.5mm plug, and will capture audio from a certain direction.
