Display Free Flash Drive Space with eInk
I’ve been following the [tag]CES[/tag] show with interest and jealousy and have set the resolution that this is the last time I’ll not be there. One of the exhibits on show was a [tag]Lexar[/tag] [tag]USB flash drive[/tag] with an eInk display to show how much disc space is currently free.
I think this is a really cool and useful use to eInk and am surprised nobody else thought of it using a more conventional display. The thing that makes eInk ideal for this use is the fact it doesn’t need constant power to keep the display, it just uses a small amount of power to change the display. As the amount of free space can only ever change when it’s plugged into a USB port it can draw the small amount of required power from there.
It’s pretty cool stuff and yet another reason why I’ll certainly be at CES next year
