README.mdSODApressed
Percussive Enveloping Noise Generator
Features:
-555 driven envelope
-Triggerable by almost anything, at any length+
-Attack cannot be retriggered until decay starts (this can make for some interesting half time hits if trigger is faster than attack time)
-Transistor Noise generator
-Beginner style DIY build
-It's mostly analog!
Notes on building: If you want a longer attack and decay, swap the capacitor on C5 from 4.7uF to 10uF (16V or larger)! Experiment! Have Fun!

Questions
How big is the Sodapressedrev4.1 PCB?
It measures 29.4 × 110 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Sodapressedrev4.1 use?
51 parts, built around the WQP-WQP518MA and MJ-3502N. 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 Sodapressedrev4.1 KiCad files?
From the djdoughy/SODApressed repository on GitHub, at the commit this page was made from: the board is sodapressedrev4.1.kicad_pcb and its schematic sodapressedrev4.1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sodapressedrev4.1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask djdoughy before reusing the design.
