A Practical LCD Writing Tablet

An anonymous reader passes along a word about an innovative LCD writing tablet. The Boogie Board costs $30, can be written on with a stylus or a fingernail, and uses no power in the act of writing. Only erasing consumes power — from a watch battery, which lasts for 50,000 erases. The total cost per "page" comes out to only 1/15th that of steno paper. The writing surface is pressure-sensitive and "highly responsive to variable amounts of pressure," so you can make thick and thin lines.

Automatic erasing etch-a-sketch

There's no way to save whatever you've drawn onto the tablet, so it's the LCD equivalent of carrying around a small blackboard and an infinite supply of chalk. Or a whiteboard with an infinite supply of ink (of only one colour). At only $30, it's reasonably priced enough that it can cater to the niche of "I want to jot down a small note that I can hardcopy later for posterity, but I don't ever want to need to worry about my pen running out of ink, as long as I remember to change the battery occasionally".

Why oh why can I not save the screen?

The thing would be awesome if I could save the screen. As it is I don't really see why I would choose it over paper since I can't save paper either, but at least paper I could store for later and write on more paper.

But it IS pretty cool.

Yeah, I would easily pay $100 if I could save things to a memory card and recall pages from thumbnails. Double that or more if it did some basic diagram aid (draw a rough rectangle, have it neatened). I've been searching for the ideal "electronic graph paper" and I have yet to find anything. It doesn't need to play movies or browse the web or send email... ok, it could have basic wifi and be able to email diagrams... but still. A few functions for drawing and writing and diagramming, some storage and searching, and that's all it needs.

That said this looks like this product probably can't even address pixels. It's probably lucky to just get enough current to the whole panel so that it clears. I doubt that requires even half the electronics of a 4-function calculator, but then I'm not an EE.
