README
README.mdMAGIC FROG'S LIGHTSABER
This is a PCB lightsaber controlled by a gyroscope and accelerometer that I designed. I created it originally for The Trail, an event organized by Hack Club.
Project Overview
I initially designed the entire board with a ATmeag32U4 chip, and you can find the schematic and PCB design in the main branch. I also added some lighthouse-themed silkscreens as my original idea was to make it a desk lamp. I encountered a lot of problems along way and decided to use an Ardunio Nano instead. I used my PCB board as a base and connected the Ardunio Nano.
Features
Dynamic LED Control: LEDs light up based on movement detected by the gyroscope and acceleromenter.
- The faster you accelerate, the more LEDs illuminate.
- Each axis (x, y, z) on the gyroscope control a different LED color: red, blue, or green.
Components
- Ardunio Nano Microcontroller
- MPU-6050 Gyroscope and Accelerometer
- NeoPixel LED Strip
- 6V Battery

Here are some really cool long-exposure light photos I took with the lightsaber in action!

Questions
How big is the Lighthouse PCB?
It measures 82.5 × 178.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Lighthouse use?
94 parts, built around the 74AHCT125D, MCP73831, MIC5219YMM and MPU-6050. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Lighthouse KiCad files?
From the themagicfrog/lightsaber repository on GitHub, at the commit this page was made from: the board is lighthouse.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lighthouse design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
