The printer, dubbed Braigo (short for Braille with Lego), was created from the Lego Mindstorms EV3 set, which retails for $349. Banerjee also added $5-worth of additional materials, which means the finished product costs about $350. This makes Braigo much more affordable than other Braille printers, which can retail for more than $2,000, according to Banerjee.
The set will let kids take on the roles of paleontologist, astronomer and chemist, using three female figures. It might also satisfy some of the demands set forth earlier this year by Charlotte Benjamin, a 7-year-old who wrote a scathing letter to the company accusing its female characters of being boring.
"I love Legos," Charlotte wrote. But, she continued, there aren't enough girls — and the ones the company has made just "sit at home, go to the beach, and shop," while the boy characters "saved people, had jobs, even swam with sharks!"
The girl's letter attracted widespread attention — and within a week, Lego responded, saying "we have been very focused on including more female characters and themes that invite even more girls to build."
