Spy edition of the open-smartwatch by @uvwxy
Osw spy is an open-source printed circuit board by akinbender, from the akinbender/open-smartwatch-spy repository on GitHub, published under the GPL-3.0 licence. It is a 4-layer board of 32.7 × 7.6 mm with 61 parts on 66 nets, routed with 691 tracks and 66 vias.
It is built around the CH340E, BMA400 and DS3231MZ/V+, with the MCP73831T-2ACI/OT-HXY and TPS2115APW among its other parts. Its parts include 23 capacitors, 17 resistors, 12 ICs, 4 switches and 3 connectors.
Based on the open source smartwatch project Open-Smartwatch by Paul's 3D Things. The rugged box is designed after this thingiverse project Check out my twitter thread about the build.
Check out Paul's instagram page, he has designed an awesome new watch. Ultimately and hopefully, I will also switch to the new board design. I dont know which changes are going to be included when, but I have some plans.
Currently there is a fully plastic test dart, and one that can be fashioned out of a M3 allen key. Depending on multiple build desicions, you can really end up hurting someone with the metal dart. This should go without saying, but I (and Paul) obviously do not accept any responsibility, I never do..
Also going to visit a local magic shop for guidance about trick darts. Magic is all about deception, most spygear too.. So maybe I might build some pyro, flash or smoke darts. Can also build an injector dart. I looked closely to my Covid vaccine injector, it can fit inside the chamber but there is no way that it can be useful.

It measures 32.7 × 7.6 mm and has 4 copper layers, 1.6 mm thick.
61 parts, built around the CH340E, BMA400, DS3231MZ/V+ and MCP73831T-2ACI/OT-HXY. 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.
From the akinbender/open-smartwatch-spy repository on GitHub, at the commit this page was made from: the board is osw-spy.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
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).
