littleBits recently had the pleasure of hosting Bilal Ghalib, a hacker aficionado and founder of both GEMSI (Global Entrepreneurship and Maker Space Initiative) and pocketfactory.org at our offices in New York City. We asked Bilal to come spend time with us at littleBits and make the craziest project he could think of.
Check out this mind-blowing project in action with an explanation from Bilal about making music with littleBits modules, an Excel spreadsheet, iPad apps and light tricks.

Adeptos de Engenhocas, e Aparelhagens Antigas, etc. eis algo que vos vai agradar, como restaurar aquelas Peças em Baquelite, esse Antepassado dos Plásticos modernos:



Restore Bakelite to Original Finish

Bakelite is an early plastic, developed at the start of the 20th century.  It was one of the first synthetic plastics ever to be produced.   All those beautiful old radios that you see for sale in antique stores are most likely made from Bakelite.   Also made from Bakelite was a lot of electrical appliances such as light switches, telephones, and also wire insulation.  The reason why it worked so well was it's high resistance - not only to electricity, but to heat and chemical action.

Ok - enough of the history lesson.   This Instructable is about how to restore Bakelite to its original shine and lustre.  Over time Bakelite starts to oxidise due to sunlight and over time will become dull.  The surface has a thin layer of oxidised material which can be removed with some careful cleaning.
