README
README.mdcamplight
camplight is a little camping warning light with neopixels. it is powered by an ATtiny85, which can be powered by a li-po battery under the pcb. the camplight would be put together using glue and some double sided tape to attach the pcb to the case, as I can't think of a better way to do it.
the pcb
the pcb files can be found in the pcb folder. it is made with kicad and you can get production files at pcb/production.
the casing
the case consists of 4 components which are the main base, the top, the button and an acrylic piece. you can find them in the models folder! (respectively, camplight-mainbase, camplight-topcover, camplight-button and camplight top cut.dxf for acrylic)
bill of materials
for some of them i got 100 because the total is cheaper

Questions
How big is the Camplight PCB?
It measures 76.1 × 25.4 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Camplight use?
36 parts, built around the ATTINY85-20PU, AMS1117-5.0, DW01A and FS8205A. 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 Camplight KiCad files?
From the codingkatty/camplight repository on GitHub, at the commit this page was made from: the board is pcb/pcb.kicad_pcb and its schematic pcb/pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Camplight design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
