Description: My PCB is very simple. There is a button that turns the LED on and a button that turns the LED off. I used a capacitor to store the charge provided by the battery through the push button and used 2 NPN transistors to amplify the current (so the capacitor doesn't discharge quickly).
Bill: 1x red LED, 4x 4.7k resistor, 2x NPN transistor, 1x capacitor, 2x push button, 2x battery cell,

Questions
How big is the Memory PCB?
It measures 55 × 51 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Memory use?
12 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 Memory KiCad files?
From the chikaskas/solder2 repository on GitHub, at the commit this page was made from: the board is source/memory.kicad_pcb and its schematic source/memory.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Memory design in my own project?
Its repository states no licence, so its author keeps all rights: ask chikaskas before reusing the design.
