Tools, writing, and eventually hardware. Built for the gap between hobbyist boards and bare-metal toolchains. One engineer, in public, with a slow but strong cadence.
For engineers who've outgrown Arduino but don't want to buy a $300 dev kit and a Keil licence to do real firmware. Proper SWD, sensible defaults, footprints that survive reflow, hobbyist price.
Build log opens on Catalyst once the schematic is locked.

Catalyst is the long-form publication side of Solarware. Build logs, hardware deep-dives, and decisions written up with their post-mortems. First posts go up alongside the dev board schematic review.
