README
readme.mdAnnoying Little Shit hardware
This repository contains the KiCAD design files for the Annoying Little Shit (ALS) device, which is an AVR ATTiny13-based device which wakes up at random intervals and beeps loudly. It is designed to be annoying.
The buzzer is rated at 80 dB @ 4 kHz, and testing has found it to be loud enough!
The firmware for the device can be found here!

Questions
How big is the Annoying little shit PCB?
It measures 33 × 23 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Annoying little shit use?
15 parts, built around the ATTINY13V-10SU, MMBT3904 and SI2319CDS. 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 Annoying little shit KiCad files?
From the frippertronics/als-hardware repository on GitHub, at the commit this page was made from: the board is annoying_little_shit.kicad_pcb and its schematic annoying_little_shit.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Annoying little shit design in my own project?
Its repository states no licence, so its author keeps all rights: ask frippertronics before reusing the design.
