article imageTwelve-year-old boy builds Braille printer from LEGO set

By Mike White     Feb 24, 2014 in Science
A 12-year-old seventh grade boy in California has built a Braille printer from a $350 LEGO set. The same type of printer would normally cost around $2,000.
According to Gawker, Shubham Banerjee calls his invention Braigo. The printer is still in the earliest stages and is slower than a traditional printer. It does work, however.
Banerjee said he would one day like to be an "engineer, surgeon, or scientist," but would probably prefer the career of an engineer. There is a Facebook page with updates for the invention.
According to Canoe, Banerjee bought the LEGO set at a Home Depot store.
Banerjee created his printer by using a basic, pre-existing pattern and reworking it with new software. He also used hardware enhancements to be able print letters in Braille.
According to GigaOm, the printer Banerjee created uses calculator paper. The printer uses robotic arms to move a module with a push pin. The pin pushes down on the paper to form bumps, then a letter. A letter can be printed in five to seven seconds.
