Josef Prusa has published a short article on a recent hack that he has done to a Netbook battery. He added a USB socket to the battery to allow him to charge devices such as i-phones independently of the PC. His Acer Wind in fact is surplus to requirements these days so this is an interesting way to recycle the old parts.
Be warned however, you can’t just wire up the USB socket to the batteries, notebook batteries output 12v or more.
