Everything that deals with my Lucid Dreaming project
Lucid is an open-source printed circuit board by breadboardbasics, from the breadboardbasics/Lucid repository on GitHub, published under the MIT licence. It is a 2-layer board of 63.5 × 31.8 mm with 41 parts on 36 nets, routed with 401 tracks and 55 vias.
It is built around the ATMEGA328P-AU, LM358 and ICL7660N, with the LM1117-3.3, MCP41010-E/P and PCF8563 among its other parts. Its parts include 13 resistors, 10 capacitors, 7 ICs, 3 diodes and 2 connectors. It belongs with the AVR (ATmega, ATtiny) boards of this library.
This is a repository for my Hackaday project here: http://hackaday.io/project/3715-tacs-lucid-dreaming-device
Thanks for checking out my project! To make everything easier just click the download zip button on the right side of the main page of this repository. Then extract everthing to a folder. Next you should be able to view the board and schematic files with KiCad or you can just view the schematic with the pdf that I included.
All code that is used in this project will also be posted in this repository and will be updated as I progress through the project.
Also for those wondering RevA (Revision A) is what I am calling the first version of the hardware. It is still a work in progress but is almost complete and ready for testing.
Disclaimer - I am not responsible for any damages or injury related to this project The project is very safe. It is battery powered and has a maximum of about 18v present on the board. Do not attempt to use the headset when it is connected to mains (the wall) in any way ex. you are powereing it with the programmer which is connected a desktop computer ect.

It measures 63.5 × 31.8 mm and has 2 copper layers, 1.6 mm thick.
41 parts, built around the ATMEGA328P-AU, LM358, ICL7660N and LM1117-3.3. 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.
From the breadboardbasics/Lucid repository on GitHub, at the commit this page was made from: the board is RevA.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
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).
