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.| — | cosma,

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. |

Electronic ones are heavily baked by now. Is there anyone here who does not know about multi-touch white boards? |

Now that we have IPv6, I am very much looking forward to realization of your suggestion, [jasper]. Since netbooks are cheaper than phones, and have their hard drives in hundreds of gigabytes, I don't see why every blackboard in Lithuania wouldn't have a memory of its lectures, available for anyone to download. |
|
| |
And now, I suppose, in the air and VR glasses? |
|

Why am I thinking luxury bed ends. Messages of love. |

I spent the last two days in an office at a law firm. It was all glass and steel and swishness, yet their whiteboard was the usual tacky-tinny white gloss-painted, aluminium-framed arrangement. They could have done with one of these. |

Yes, well, sooner or later your family's idiosyncratic version of "hide and seek" is going to get one of you into serious trouble. We recall the Intercalary's brief yet incident-packed sojourn at Whipsnade Zoo - his choice of both location and disguise were singularly ill-chosen, given that it was the height of the mating season. |
|
| |
I agree, whiteboards as they stand are dreadful, and
shockingly expensive. Getting a marker that works at all is
never easy, getting a couple of colors is asking an awful lot.
I think a nice milky polypropylene with RGB LEDs behind
would work well. Then you can write on it with red green
and blue pens and selectively make certain colors stand
out/disappear. |
|
| |
//ill-chosen// We thought so too, until we noticed the smile on his face. |
|
| |
We Buchanans have, over the generations, elevated Hide & Seek to a level where we are considering petitioning to have it included in the olympics. We have quite a comprehensive if rather baroque system of scores and penalties, and I personally consider myself something of a semi-pro. |
|
| |
It is my foolish dream to one day surpass the score of Finbarr Goyles-Goyles de Bucque-Annan (one of our more distant relations with some unfortunate genes). He was the first player ever to get over 100 points, back in 1776. By the time we find him, it's quite possible that his score will be into four digits. |
|

(It was claimed, of course, that captain Guiles Buchanan, of the Westford branch of the family, had scored a "double round" of 980 points by remaining unfound throughout the 1800's without ever leaving the Old Library. This would have been an astonishing feat of concealment - especially as the Old Library was burned down in 1871. However, his score was discounted when a careful check of the family tree revealed that there had never been a Guiles Buchanan in the first place.) |
