DIY Spectrometry, Mind-Controlled Drones, Javascript Games, and Open Source Font

  1. DIY Spectrometry KitThis open hardware kit costs only $35, but has a range of more than 400-900 nanometers, and a resolution of as high as 3 nm. A spectrometer is essentially a tool to measure the colors absorbed by a material. You can construct this one yourself from a piece of a DVD-R, black paper, a VHS box, and an HD USB webcam.
  2. Mind-Controlled Drones — Chinese demo of EEG to Bluetooth to laptop to wifi to UAV.
  3. Pac-Man in Javascript — in-browser loving recreation of a bunch of original Pac-Man games, with source on github. Cf this article on building Atari Arcade in CreateJS. (via Javascript Weekly)
  4. Source Sans — Adobe’s first open source typeface.
