Arya Goutam and Alec Vercruysse
This work, completed as a final project for E155 at Harvey Mudd College, takes in music input via a 3.5mm audio jack, and syncs a diffraction-grating based laser light show to respond to percussive elements in the song. Read our final report for a description of the design and algorithm.
Due to the requirements of the project for the class, all SystemVerilog code, including that for the FFT, was written from scratch.
fpga/contains the SystemVerilog code used to interface with the PCM1808 ADC, the FFT module, and the beat tracking algorithm. It also includes the python files used to generate the twiddle and hann windowing look up tables.mcu/contains the code for the microcontroller, which was responsible for selecting patterns, driving the servo, and controlling the relays.adc/contains the design files for the PCB developed to interface the ADC with the development platform we used for the classpapers/contains the initial project proposal and final reportsim/contains the jupyter notebooks used to prototype different parts of the design.

Questions
How big is the Adc PCB?
It measures 72.4 × 55.9 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Adc use?
15 parts, built around the PCM1808PW, RCJ-2123 and SJ-3523-SMT-TR. 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 Adc KiCad files?
From the AlecVercruysse/ATLAS repository on GitHub, at the commit this page was made from: the board is adc/adc.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Adc design in my own project?
Its repository states no licence, so its author keeps all rights: ask AlecVercruysse before reusing the design.
