Six pieces of brand collateral built on the same engineer's-notebook tokens as the website: industrial yellow #F7B500 against a deep charcoal bench, Manrope for narrative type, JetBrains Mono for metadata and part numbers, and a strict 24-grid silkscreen.
Dark surfaces drive every screen; paper variants kick in on print. Industrial yellow is the only accent — used sparingly to draw the eye, never used decoratively.
Verified engineering reference for embedded systems. Every tutorial bench-tested against a logic analyzer, a power profiler, and an oscilloscope.

Front is a clean lockup with name + role; back becomes a quiet spec sheet. Both sides print in single-color black + an amber spot — no gradients, no varnish.
Hi Adafruit,
I run Circuit Essentials, an electronics-education site with one rule: every tutorial is bench-tested before it's published — verified code, real scope measurements, and named gotchas. I'm writing to apply to the Adafruit affiliate program for the part links in my parts-list tables.
Happy to send a list of upcoming articles. Thanks for considering.
