He also explains something I didn't know about the 3 volt Lithium button batteries: what the numbers mean!
Take the CR2032 for example...
This can be read as:
CR - 20 (Diameter) 32 (3.2mm thick)
Ace!
If he could get some E-Ink display - I bet he could get it thinner than 2mm.
Ahha! 1mm : http://www.pervasivedisplay.com/FAQRetrieve.aspx?ID=43351 |
