Unconventional Switch: Novelty Letter Opener

 After going through a number of wildly different concepts and being squashed by material limitations, my partner and I came up with the idea of using this novelty letter opener to connect our circuit! Most of the circuit is cut and dry: 9-Volt battery charging 2 red LED's through 3 100 Ω resistors, connected by 2 ends of copper tape running through the helmet and completed by the sword itself.

The plan was initially to drill into the helmet and tape the LED’s in such a way that the light shines through the eye holes of the helmet, but the sword itself would’ve interfered with the potential path of it.

Thank you!
