The iPod battery unplugged (NOTHING wrong with your iPod that you can’t fix yourself).
Another glimpse from the past: pre-MAKE (and tru vintage) Modern Mechanix. On of the reasons I like those old DIY magazines is because good artists (that was long before color photography, best beloved) like Boris Artzybasheff drawed nice pictures there. (So I’m not surprised to see that boingboing has a lot of posts about Mr Artzybasheff).
Here’s the Joule thief. It’s like an open PCB torch that will take either an AA or AAA battery in the holder and use whatever power is left in the battery to light a white LED. The amazing thing about this circuit is that it will run right down to about 0.35V if left running continuously, and will often provide a week of continuous low level light from a battery that would normally be considered dead. The level of light is initially quite high but gradually reduces as the battery voltage goes lower. However, it can still be used for reading in a dark room, even when the battery is almost completely drained. (via)
