It never needed external validation of its accuracy anyway. Just like me.

Identifying rhetorical situations, including audiences, has been an important step to take before writing.

When we lacked parts, I dismantled old machines; when we couldn't afford physical testing, I trained members in computer modeling.

I needed a high-quality audio device that everyone could fit and afford. I would have to make my own.

After the hackathon chaos, I immediately redesigned a proper servo driver shield - PD3.1 power delivery, Pico coprocessor, and 24A buck converters. Sometimes you just need to build the tool you wish you had.
