Yet again, using inkscape and the svg2shenzhen extension to create a sort of artisy PCB. Just a cute blinky wearable shaped as a cat because we like cats.
Inkscape layers
The design suite is KiCad, this is a really simple circuit the IC controlling the LED has 2 NPN transistors. Just like our cat badge but using 1 LED.
RC circuit
We wanted the pin to have a smooth look on top so we had exposed copper with HASL finish and did all the routing on bottom.
Routing on bottom
We ordered from JLCPCB and the components from LCSC. Very few components so is easy to hand solder, and the LED is placed upside down.

This is a video of me wearing it with on my coat.
Cats cats cats!
