List of unexplained sounds

Upsweep[edit] Spectrogram of the Upsweep sound Upsweep is an unidentified sound detected on the American National Oceanic and Atmospheric Administration's equatorial autonomous hydrophone arrays. The sound appears to be seasonal, generally reaching peaks in Spring and Autumn, but it is unclear whether this is due to changes in the source or seasonal changes in the propagation environment.

The Tesla Gun

The War of the Currents was well underway. At stake: the future of electrical power distribution on planet Earth. With the financial backing of George Westinghouse, Tesla’s AC polyphase system competed for market dominance with Edison’s established (but less efficient) DC system, in one of the ugliest and most epic tales of technological competition of the modern age. More than a hundred years after the dust settled, Matt Fraction and Steven Sanders published The Five Fists of Science: a rollicking graphical retelling of what really happened at the turn of the last century.

(Get yourself a copy and read it immediately, unless you’re allergic to AWESOME). See that dapper fellow in front? Yep. As I read this fantastic story, gentle reader, certain irrevocable processes were set in motion. The Tesla Gun is a hand-held, battery powered lightning machine.

Mac Power Adapter + Beer Bottle = Apple's Secret Church Key. KegDroid : une tireuse à bière sous Android. KegDroid : une tireuse à bière sous Android Un certain Paul Carff s’est lancé dans la conception artisanale d’une tireuse à bière Android (certains d’entre-vous ont déjà les yeux qui brillent).

KegDroid : une tireuse à bière sous Android

Reprenant la forme de Bugdroid, celle-ci est dotée d’un système Arduino et d’une tablette Xoom (tournant sous ICS) qui vous permettra de sélectionner la bière et la quantité que vous souhaitez. Pour interagir avec cette charmante tireuse nommée Betsy, notez qu’il vous faudra avant tout vous munir d’une puce NFC qui gérera vos crédits. Démonstration en vidéo dans la suite !
