Overview
Solder PCB is an open-source printed circuit board by angle-mad, from the angle-mad/Pumpkin_PCB repository on GitHub. It is a 2-layer board of 90.3 × 99.2 mm with 14 parts on 9 nets, routed with 63 tracks and 0 vias.
Its parts include 6 resistors, 3 diodes, 1 transistor and 1 switch.

I made a PCB in the shape of a Pumpkin.

Falstad Simulation
I made a test circuit of the PCB on Falstad but with a potentiometer to simulate a photoresistor.
Onshape
I used Onshape do to create to edge cuts for the pumpkin PCB. After sketching the area in Onshape I can export the sketch as DXF and import it into KiCad. I did this to make the edge cuts as well as some of the silkscreens and outline for the FR4 art.
Krita
I used Krita to make silkscreen art of my Initials
Features
- When the photoresistor is subject to the dark the 2 LEDs in the eyes will turn on and when not the LEDs should stay turned off
- When push button is held down the LED in the mouth will turn on until not held down
- PCB has custom made silkscreen art on front and back
- Pumpkin stem on PCB has exposed FR4 to differentiate it from the pumpkin body and I made a hole through it in order to make it a keychain

Questions
How big is the Solder PCB PCB?
It measures 90.3 × 99.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Solder PCB use?
14 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 Solder PCB KiCad files?
From the angle-mad/Pumpkin_PCB repository on GitHub, at the commit this page was made from: the board is KiCad-Files/Solder_PCB.kicad_pcb and its schematic KiCad-Files/Solder_PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Solder PCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask angle-mad before reusing the design.
