Requirements
Problem statement - drills are throwaway devices. They break and you can't fix them readily because they are not appropriate technology. Here we design the world's first appropriate technology cordless drill.
The goal is to select an appropriate @Depth of Modularity to make any cordless drill motor, battery, speed trigger, gear set, and Chuck interoperable with any other.
This converts any drill to one about 10-100 times cheaper (lifetime extends from 1 to 100 years, and cost drops from 100 to about 25 for the initial purchase, so all things considered, the open source version is about 100x cheaper over the lifetime.
