Liz from Blitz City DIY wrote about the process of designing a PCB ornament:
As the holidays approached this year, I felt a need to create a DIY gift for my family and friends. I struggled at first to find a medium. Should I 3D print something? Should I knit? But then it hit me: everyone loves blinky LEDs and I want to keep getting better at PCB design. I’ll do a PCB ornament!
If you don’t have a traditional electronics background PCB design can seem scary, overwhelming and something that’s meant for more experienced people that have “real skills”. If you start simple and slowly add-in new methods and design features to your boards you’ll soon realize it isn’t so scary and that much like everything else in life it just takes practice and patience to learn. And once you have your first project on a custom PCB instead of a piece of perf board you’ll be hooked.
From a cockroach filled with LEDs, to an impressively dense 576 RGB LED display, and even a hunk of carpet, our final installment of the unofficial hardware badges at DEF CON 26 are beyond impressive. I tried to see every badge and speak to every badge maker this year. So far we’ve covered a ton…

KiCad presentation by Andrew Sowa at Teardown 2018:
While most PCBs can be simple rectangles, sometimes the design requires more complex geometry. EDA tools don’t always make this simple, so we will go over a few KiCad tips to make it easier. In this talk you will learn how to import unique board shapes from Fusion 360, create arbitrary fill zones using images, and embed high-frequency RF filters. We will use multiple software packages to enhance KiCad’s performance beyond its obvious use.
From John Baichtal on Hackaday:
[jg] recently passed some damaged Braille signs and took on the challenge of repairing them. Informed by his recent work on PCB lapel pins, [jg] immediately thought of using circuit boards for this project. He’d noticed that round solder pads made for uniform hills of solder, and this reminded him of the bumps in Braille.
He began by reading up on the standards of the Braille Authority of North America, which stipulates a dot height of 0.6mm. He loaded up the PharmaBraille font system and laid it out the dots in photoshop, then and imported it into KiCad and laid out the boards. When the PCBs had arrived from OSH Park, [jg] soldering up the pads (lead free, but of course) to see if he could get the hills to 0.6mm. He’s experimenting with different methods of melting the solder to try to get more even results
JinGen Lim created this beautiful project:
I had little experience with fabric, but building a lapel out of PCB seemed like something that might just work. PCBs are typically built with extremely high tolerances for its copper and mask layers and still acceptably accurate for the silkscreen.
