This is a hobby project of building an ALU, CPU, computer, or whatever it ends up as before I tire of it, from basic components. Think of it as a learning and art project more than anything practically useful.
Inspirations include:
- That ALU built in minecraft
- Boldport Club for sending me beautiful, fun, whimsical and/or useful kits to assemble; and for its community of other tinkerers showing off their projects
- Crash Course Computer Science for making me think "that should be fun, how hard could it be?"
- The MOnSter 6502 and Megaprocessor
Special thanks also to the Boldport Club community for providing newbie help as I try to figure these things out!

Questions
What parts does the Full adder exploded use?
27 parts. 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 Full adder exploded KiCad files?
From the emlun/octobot repository on GitHub, at the commit this page was made from: the board is 8-bit-adder/full-adder-exploded.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Full adder exploded design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
