In Pi Wars, there are a lot of puzzles and problems to solve. Some are hard, some are easier, but they are all fun, an opportunity to learn, experiment, do something crazy – that’s the whole point! But there is always one (or two!) completely new problem that turns up totally unexpected, usually at the worst possible time, and messes up all your plans. The famous unknown unknowns… These are usually not much fun.

This was an easy and reliable solution to avoid any interference from electrical noise generated by DC motors. But it’s not very efficient: the batteries will not discharge at the same rate – and just two would probably provide enough total capacity anyway. This time we want to reduce the weight and also save some space.
