It all started in Physics class. Harpo and I had just finished our AP Physics B and our AP Calculus BC tests. Although we still had over a month left of school, two entire classes were now free periods. Our class discussed options; some of us decided to chill and/or pass high school, or others, such as my associate and me, decided to figure out some stellar project. We considered many things and often defaulted to pyrotechnics or the Arduino, but found that we often came back to LEGO®. Harpo and I, as well as our buddy Lyle, all used to be really into Legos. All of us had an interest in creating a two-speed transmission from them, simply because that was a task that none of us had not been able to tackle.
