Shayna : PCB Artwork Hack Chat starting soon, everybody!
Shayna : Post your questions in the discussion on this page :) https://hackaday.io/event/112119-pcb-artwork-and-photo-conversions
Just was looking at some of my really old PCB art... :-D

Shayna : Hey @Andrew Sowa !
Shayna : Thanks for joining us for this Hack Chat today
Shayna : We'll get started in around 10 mins or so
Wahoo, I'm looking forward to this one!
Shayna : Before we get rolling, would you like to tell us a little about yourself @Andrew Sowa ?
I'm a electrical engineer from Chicago and for my day job I make LED light fixtures. I am a contributor to the Supply Frame Hardware blog and
got start with PCB art stuff by making the Benchoff Nickel after a long night on Kicad layout for a crowdfunding project I was working on
Since then I have evolved that into my signature style for lack of a better phrase of turning photos into pcbs.
Shayna : awesome!
Shayna : Mind if we get started on the questions?
Shayna : Please also feel free to share any images/projects you'd like folks to take a look at, too
Shayna : I think I know that person :)
This is my latest project. It was requested that the hair needs to be pink so I have been working with halftones to make the contrast while also back lighting the bare FR4
where does the pink come from?
Shayna : Very cool
Shayna : Alright, first up from @zakqwy : "I do a good bit of Inkscape --> KiCad graphics work and am by and large happy with the process. However, a lot of my custom graphics also function as electrical elements, usually ground planes or touch sensors. Any thoughts on making custom footprints that KiCad actually recognizes as such for routing and fill purposes? Right now wiring graphic bits up to a circuit is a process that can't take advantage of KiCad's excellent on-the-fly DRC bits, making the technique prone to errors."
I just figured out how to do this while still keeping the DRC working this morning
ah awesome! share your secrets!
i would love push 'n shove to route around my copper graphics
In Kicad 4.0 you could only do specific shapes for footprints so any polygon gets put in but not processed properly from a DRC perspective. There is also an isssue where the edge cuts also don't get caught with DRC
i like when you can integrate your artwork witht he electrical connections
with 5.0 the edge cut thing is fixed but they also added arbitrary shapes for footprints
can i still import 'em via bitmap2component from an *.svg file (or elsewhere)? or do i have to make the footprint itself in kicad?
You can use the bitmap converter to get all the points you need to put into the text file and use this new formatting to get it to process correctly. This is a little hard to explain in text but I'll try my best
What's the edge cut thing?
