Apparently, our student was strong enough to break the prototype for the bow hand, which is actually a good sign! In order to allow him to get more leverage and allow the bow to flex while playing, the student team got together and produced this next version this past weekend. Off to testing!
The CA student team is meeting with Cesar and his teacher Cynthia this coming Friday/Saturday to make a series of incremental upgrades to the current prototype. While it worked well during the summer festival, the connection between the bow and the prosthetic was still a work-in-progress and to our surprise the structure has degraded significantly. We think this is a positive sign though, that Cesar is able to exert that much force using the arm and draw a big sound on his instrument...now we have to make it stronger!
