Main components

README.mdFalloutTimer
The FalloutTimer™ is a simple timer that uses an RTC, A pi Pico, Some buttons, and some cheap 7 segment displays to tell you how much time is left in Hack club fallout! (Can be used for other things as well)
Assembly
Assembly is relatively simple, Solder the pico, buttons, caps, and RTC, into the spots they appear on the pcb/zine. look at the zine for info about how to solder the 7-seg display, then flash the firmware by holding down the boot button on the pico while plugging it in. then compile the code and drop the uf2 into the pico's flash. it should reboot and work. Thats really all you need.
Usage
Simply set the time via the buttons on the bottom. left button controls days and hrs, left controls mins. seconds are always set to zero for simplicity. if you click the left button it will change hrs, if u hold it down, then it will change days. Thats basically it.
Why?
I decided to make it because i need more time for fallout and it seemed like a simple project i could do to increase my amount of approved hours. also it looks cool as wall deco. ill probably bring it to fallout to show the amount of time left It displays the time left in fallout with Day,Hour,Minutes,Seconds, similar to the fallout website. also i might get it to check streaks too maybe? <- no wifi so probably not. u would need a pico w aswell.

Questions
How big is the FalloutTimer PCB?
It measures 53 × 56.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the FalloutTimer use?
12 parts, built around the DS3231MZ+. 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 FalloutTimer KiCad files?
From the Broseph9972/FalloutTimer repository on GitHub, at the commit this page was made from: the board is Kicad/FalloutTimer.kicad_pcb and its schematic Kicad/FalloutTimer.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the FalloutTimer design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
