Chapter 26 - Let’s make our own PCB #

[TODO]

  • Make it work
  • Make it not emit a ton of RF or go to shit when around it (everything is an antenna)
  • Make it pretty
    • ref that weird russian autorouter as limits on this
  • Make it repairable
  • Know when to do a PCB or a Perma-Proto
  • Assuming parts will only be available for so long

First things first, we’re going to be using Kicad, so you’ll want to go grab that from the repos. While that’s downloading and installing give this a watch to get the basics down:

Chapter 26.1 - PCB Components #

[TODO] Antennas (2.4ghz mostly), Spark gaps, coils, PCB capacitor, distributed element filters, flexible PCB as connectors

and technically resistors and fuses, albeit … eh.

0-ohm resistors to keep 1-sidded
