MCGoL
MCGoL ist ein modulares Open-Source-Platinendesign für Conway's Game of Life, das als kollaborative Aufgabe in einzelnen Modulen aufgebaut und zusammengesetzt werden kann.
Was ist Conway's Game of Life?
Conway's Game of Life ist ein zellulärer Automat auf einem Raster aus Zellen. Jede Zelle ist entweder „lebendig“ oder „tot“. In jedem Schritt wird der nächste Zustand ausschließlich aus den Nachbarzellen berechnet – dadurch entstehen aus einfachen Regeln komplexe, oft überraschende Muster.
Technischer Ansatz von MCGoL
Die Matrix ist ausschließlich aus diskreten Logikbausteinen aufgebaut. Dazu gehören unter anderem:
- 4-Bit-Addierer
- Schmitt-Trigger
- Triple-AND-Gatter
- Flip-Flops
In der Matrix selbst werden keine Mikrocontroller eingesetzt.

Questions
How big is the CWOLv2 PCB?
It measures 80 × 80 mm and has 2 copper layers, 1.6 mm thick.
What parts does the CWOLv2 use?
43 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 CWOLv2 KiCad files?
From the EmilAltmann/mcgol repository on GitHub, at the commit this page was made from: the board is hardware/pcb/CWOLv2.kicad_pcb and its schematic hardware/pcb/CWOLv2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CWOLv2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask EmilAltmann before reusing the design.
