A Song of Ice and Fire
The “Smart Mitten” went through various stages of development. Our team had moments of jubilation and defeat. Transistor after transistor went up in smoke, voltage regulators fell like flies, even our PCB design crumbled before our eyes. With tears streaming down our cheeks we pushed on through the early hours of the morning fighting against the impending deadlines. We faced challenge after challenge as we debugged our glove trying to make it smarter and smarter.
Our initial PCB design created the most issues for us. Hours went into diagnosing issues and attempting to work around shortcomings in the design. Ultimately, we had to give up on our design, we were too ambitious in what we thought we could achieve. With no time left to re-order a new PCB design we had to get creative. We scrounged some spare relays and threw together a new design. With a laser jet printer, youtube, some ferric chloride, and an fr-4 board we got to work. After some dangerous ironing and a few slices of pizza we had a new board that worked like a dream after a few hours of tweaking.
The final issue that turned our working “Smart Mitten” into a brick was sadly beyond our control. At some point leading up to the expo we shorted the MSP432. Slowly, the chip heated up more and functionality of the glove started dropping off. With dejected, bleary eyes we sadly watched our glove die until it was reduced to a shadow of its former self. Though our original board did not survive, the code lives on.
Once transferred to a new and healthy board, the spirit of our glove lived on and we found success again. The warm glow of the heating elements comforted our sadness at losing board #1.
