Questions
How big is the Spark inducer PCB?
It measures 233.3 × 128.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Spark inducer use?
116 parts, built around the TL072HID and APT3216EC. 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 Spark inducer KiCad files?
From the 30350n/spark-inducer repository on GitHub, at the commit this page was made from: the board is spark-inducer/spark-inducer.kicad_pcb and its schematic helper-jack/helper-jack.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Spark inducer design in my own project?
Its repository publishes it under the CERN-OHL-W-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
