Freeform "SevenSeg" Bot Workshop with special guest Mohit Bhoite


On April 25th, we had the privilege to host a workshop by Mohit Bhoite on building free-form circuit sculptures. During the workshop, Mohit walked us through a small project and covered planning, materials, methods and tips. By the end of the event we each had started our own "SevenSeg" bot.

You can make fun things while you're stuck at home!
Jenn reached out to Mohit Bhoite, an electronics engineer at Particle who makes freeform circuit sculptures for fun. He agreed and was excited about teaching a workshop to us!
He partnered with MTRAS to do a Zoom webinar workshop, building his SevenSeg bot design on April 25, which was National Sculpture Day! Jenn also worked hard to get and deliver kits before. Despite vendor and shipping delays due to supply chain issues in this era of COVID-19, she was able to help produce a fantastic event!

We are also very thankful to Mohit for agreeing to share his knowledge with us. To learn more about what he does you can view our recording of the event below. You can also view his gallery of projects on his website:
