AAAA: dns record and battery*
@quad this is fake news
@pea pretty sure there's A batteries too, but they're completely dead. Unlike AAAA batteries which still exist in some weird corners
@quad @pea the Wacom Bamboo Ink pen and some of their iPad pressure sensitive pens use AAAA batteries. I had to order them from shady shops with probably shady DNS records so it all comes around.
@lastfuture @quad @pea You can also pry open a 9 Volts block battery. Good chance to harvest six AAAA batteries, although with soldering lugs. https://blog.xkcd.com/2007/08/20/testing-the-9v-battery-hack-or-assault-on-battery/
