Making a Lego Clockwork Pendulum Generator

Well it’s that time again to make yet another wildly impractical generator using Lego Technic. For this iteration, I was interested in building a mechanism to allow a slow release of electrical energy so that we can power a small LED light for an extended period of time. The principle is simple: a wind-up motor stores some energy, which is then released via a clock-like escapement mechanism which drives a pendulum. And the pendulum weight consists of some large neodymium magnets which swing between a pair of copper coils, generating a small trickle of electricity over time. This Lego generator doesn’t produce much power, but it’s enough to power a small ‘night light’ for a couple of minutes. And I personally enjoy the satisfying tick-tock noise it makes as it runs. Please let me know if you can think of any other applications that require a small amount of power over a period of several minutes! #lego #generator #energy #power #gadgets
