Heavy executive whiteboards,
milky glass held gingerly in mahagony frames,
for use in front of window office walls.
Electronic Ink

Very small two-color balls embedded in a flexible material with electronic control of which side faces out; "e-paper" [cosma, Dec 23 1998]
Zombieboard:

Smart camera images whiteboard. Has a URL, also drawing on board controls scanning camera. [rmutt, Dec 23 1998]
White Tint

You'd have to add your own wood frame. [reensure, Dec 23 1998]

I saw a whiteboard that has a printer attached. The whiteboard drawing surface is a big belt that wraps around the back of the board, with a roller at each side. When you want to keep the drawing, you press a button, and the whiteboard belt is drawn past sensors, and the printer outputs a date stamped, condensed image of the whiteboard on paper. |
|
| |
Also, the blackboard seems to be almost completely gone, the same way that the CD vanquished the LP record. |
|
| |
Let's make it easy. All whiteboards should have URLs. |
|
| |
If there was any way to create a read-write "smart paper", that would be great. I hate the smell of whiteboard pens and cleaner. A stylus would be better, and the fidelity of the e-transcript would be exact. |

E-paper (a la Electronic Ink; see link)
behind a touch-sensitive surface
should do the trick. Need to make sure
the e-paper is thin and flexible enough,
of course.

Why not make giant versions of those magnetic "Magic Slate" drawing things that children have?
(Damn! Children have all the best toys!) |
|
| |
I use a small "magic slate" to take quick notes with my Palm/Pilot stylus when Graffiti(tm) would be too slow. The problem is that each slate is only good for a couple of weeks before the wax gets too rutted. |
|

Back to the original... I'd pay a lot for a whiteboard that wiped off perfectly every time, no matter how long it had been, without having to use liquids. If it looked pretty, that would be a nice bonus. |

egnor: One useful tip for erasing stuff that's been left up too long is to scribble on top of it and then erase. The new scribbling contains solvents which cause the old ink to flow and thus be erasable. |
|
| |
Yes. Also, some brands of markers erase better than others, and even within a brand individual colors often exhibit different degrees of "stickiness". Some cleansers tend to degrade the board surface over time... |

Good reason to use the technique I described. |
|
| |
Eeyore: Try putting the 'magic slate' under a towel or a couple of paper towels or something and ironing it lightly. Should reflow the wax enough to help. |
|

hopefully this isn't too off the subject, but does anyone remember that toy that Nickelodeon came out with that flashed a green light that made the wall glow for about a minute? They were marketing it as a sort of "silhouette maker." Maybe it was radioactive.. |

Some friends kids had one of these and we spent a night playing with it. The screen was just glow in the dark, and the 'pen' had a flashlight bulb and a camera flash. A strobe puts out enough energy to light the whole screen up dimly, and the flashlight puts enough in to light it up brightly in a localized area. |
