It took a bit of LEGO and some dirt-cheap hardware to fashion together the world’s first truly affordable Braille printer. At a stroke, Shubham Banerjee’s open-source ‘Braigo’ (from ‘braille’ and ‘LEGO’) cuts the cost of braille printers, from $2,000 to just $350.  Not bad for a 12-year-old.

‘Assistive technologies are either too expensive or difficult to obtain for normal people,’ says the Californian high-school student, who has been dubbed a boy genius and tipped as the next Steve Jobs or Bill Gates by CNN.

He was inspired to make the machine when he saw a charity leaflet fundraising for a printer. After seven attempts prototyping, using a basic, pre-existing pattern, he’d built a machine and software programme that could render the six dots that make up the tactile writing code – using a standard LEGO Mindstorms EV3 robotics kit, printing onto standard calculator paper and with a thumbtack as its primitive printer head.

‘I’ve been building my whole life,’ said Banerjee, whose father is an engineer. ‘When I learned how many people can’t afford to buy a braille printer, I realised I could probably build a solution... [and] thought it would be cool to make [it] completely out of LEGO.’

The prototype is slower than commercial models – taking five seconds to print a character. But Banerjee is tweaking the model to speed it up, and incorporate other elements such as text-to-speech software.

The invention was Editors Choice at Maker Faire’s flagship Bay Area Faire 2014, and Banerjee was among delegates to the first ever White House Maker Faire this summer.
