Wesley Pereira de Souza, a 15-year old boy from Tocantins, Brazil, has a great future as an engineer. He built this hydraulic excavator arm using just plastic tubes, wood and syringes.
I saw this video floating around the internet a couple of weeks ago, but couldn’t find any corroboration of its authenticity. Now we have photos of the arm and more information courtesy of Core77.
That is a thing of beauty.
