README
README.mdAnalogical
This is Analogical; a project I've made for chipless.hackclub.com, The main goal of this project was to learn analog and not use a microcontroller!
It is a 6 node transistor only signal network where each block drives, perturbs and destabalises the next creating a really chaotic annalog behaviour which cannot be replicated with a MCU
I have used the cheapest shipping options and it comes to a total off: $22.48

Questions
How big is the Chipless PCB?
It measures 59.2 × 74.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Chipless use?
61 parts, built around the AMS1117-3.3 and 1N4148W. 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 Chipless KiCad files?
From the Rohan317685/Anological repository on GitHub, at the commit this page was made from: the board is src/Chipless.kicad_pcb and its schematic src/Chipless.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Chipless 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).
