Challenge Center Unleashes Inner Engineers

This article appeared in the January 23, 2015 edition of the Davis Enterprise.

What’s the coolest thing you’ve ever made out of Legos? A doll house? Maybe a toy car? What about a sofa you can actually sit on? Or how about a fully functional record player or chain saw?


People are using the ubiquitous child’s toy to make all kinds of useful things, but last year a seventh-grade science fair project may have topped them all. Twelve-year-old Shubham Banerjee used a Lego Mindstorms kit to build a Braille typewriter.


After learning that typical Braille typewriters, used to create print material that can be tactilely read by the blind and visually impaired, cost upwards of $2000, Banerjee wondered if he could use more familiar materials to design a less costly one. Cheaper Braille typewriters could make the written word more widely accessible, especially in the developing world.


So Banerjee adapted an existing printer design with some hardware and software modifications, a keyboard and a thumbtack to punch the bumps into the paper. That’s how the Braigo machine was born.


But Banerjee hasn’t stopped there. He’s continued to upgrade his design by adapting traditional desktop printers to make the Braigo more efficient and even more affordable.


He’s now thirteen and has started his own company, Braigo Labs, to hopefully perfect the design and begin mass-producing them. His ingenuity has paid off by attracting the attention of tech companies like Intel that have invested in Braigo Labs to help Banerjee hire a team of engineers.


Beyond the commercial success that looks like it’s coming Banerjee’s way, the Braigo machine has the potential to change the world in a positive way. At Explorit Science Center, we encourage the kind of thoughtful innovation that isn’t satisfied with the status quo. And we’re big believers in using everyday materials to do extraordinary things.


That’s the whole philosophy behind our Challenge Center, an engineering and design lab open to the public where you can tackle a design challenge such as building a bridge or constructing a catapult with recycled materials.


Maybe you’ll find some toilet paper tubes or yogurt cups. Maybe there will be cereal boxes and produce baskets. These plus scissors, masking tape and your imagination could be the raw materials for something amazing.


The Challenge Center is open Wednesdays, Saturdays and Sundays, 1:00 p.m. to 5:00 p.m. and Fridays, 3:00 p.m. to 6:00 p.m. alongside our museum exhibition, and is free with paid admission to the museum. Check it out at your next visit and discover what you can create!


Explorit’s coming events:


  • Explorit’s Beautiful World: Science and Art exhibition is open to the public every Wednesday, Saturday and Sunday, 1:00-5:00 p.m. and every Friday, 3:00-6:00 p.m.  Admission is $5.00 per person; Explorit members, teachers and children 2 and under are free.
