For this category I decided to build a parallel plate capacitor. Parallel plate capacitors are rarely used in technology because coiled capacitors are much more space efficient, but they are great tools for teaching physics. My bookend design is based off a parallel plate capacitor from the early 1900's, with positionable plates and a wooden base.
The metal plates are able to hold an electric charge, and then discharge it into a circuit. They discharge faster than batteries, making capacitors useful for things like camera flashes where you need lots of power quickly.
The base must be non-conducting, hence wood is used here. Since a parallel plate capacitor stores power, and they say knowledge is power, I thought it a fitting build for the category. Additionally, since paper has a higher dielectric constant than air, if you store books between the plates of a capacitor you'll actually increase the charge it can hold.
The back. Reversing the direction of the studs for the side edge panels took some messing around in the internals, but allowed me to keep the back panels as thin as the door piece used.
Nice work Luke! Really like both the build and the story behind what you were trying to replicate in Lego. The use of those Star Wars turret thingamabob pieces works exceptionally well, especially when coupled with the well textured wooden blocks. Another fine piece of Lego work, keep it up! God bless, ~Promar~
Great work on this - as a big nerd myself I can appreciate this. They also remind me of landing struts on a spaceship or something. A Sci-Fi book in the middle perhaps. Anyway since this is both out of the box in both look and subject matter chosen for a book end - you have won my vote! Good Luck with the other judges.
