A simple little PCB toy designed for Hack Club's Solder YSWS.
This little design uses an NPN transistor, a photoresistor, and a SPST switch to bother all your friends endlessly. When switched on and placed in an environment with low light (like your friend's bag) it'll buzz utilizing the vibrating motor until turned off or brought into light. The light sensitivity can be adjusted using the potentiometer.

Questions
How big is the GuacSolder PCB?
It measures 44.9 × 60.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the GuacSolder use?
8 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 GuacSolder KiCad files?
From the scherepi/bothertoken repository on GitHub, at the commit this page was made from: the board is GuacSolder.kicad_pcb and its schematic GuacSolder.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the GuacSolder design in my own project?
Its repository states no licence, so its author keeps all rights: ask scherepi before reusing the design.
