The Basics

​Join us for Maker Summer School! In this summer series, you can learn how to design your own printed circuit board using the free open source (FOSS) software package KiCad.

  • ​Over four evening sessions, we'll take you on a gentle dive into the typically hidden-world of everyday electronics and help you start to make your own.
  • All sessions takes place from 18:30 in the 42 auditorium
  • The first session is a general intro to the topic, to see if it's your thing
  • If you like it join the "learning pact" for the next 3 weeks to design and send for your own board
  • The best finished boards will be sponsored by the school

From LED 'blinky' badges to, mini-keyboards and games-consoles, circuit-board jewelry and synthesisers - we'll take a look at a series of example projects that we’ve produced over the last year and use those as jumping-off points for your own designs. So whether you're a budding hardware engineer or an artist looking explore a new fabrication technique - you'll find the practical tools you need here.

​And of course we’ll learn some electronics too as a side effect :)

Questions

What parts does the WeevilEyeMod use?

8 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 WeevilEyeMod KiCad files?

From the fablabnk/PCB-SummerSchool repository on GitHub, at the commit this page was made from: the board is Project2_WeevilEyeMod/WeevilEyeMod.kicad_pcb and its schematic Project1_BlinkyPartsUnicorn/unicorn.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the WeevilEyeMod design in my own project?

Its repository states no licence, so its author keeps all rights: ask fablabnk before reusing the design.
