3. Braigo
Braigo is the name of a Braille printer design. Braigo version 1.0 uses a Lego Mindstorms EV3 kit, which includes a microprocessor with assorted components such as electric motors, sensors and actuators. Braigo v1.0 was designed by 13-year-old Shubham Banerjee in January 2014, as an entry in 7th grade school science fair project. The cost was said to be about 350 USD or 250 Euros for the Lego Mindstorms EV3 kit and some extra commonly used hardware whereas a conventional Braille printer retails starting from about 1,900 USD. Over the summer[vague] of 2014, Banerjee reported about working on ‘Braigo v2.0’ which promises to be a consumer version of a braille printer/embosser.
