Bench log
Every filed sheet — soldering, robots, circuits, controls, and field notes.
- PID tuning without the spreadsheet theaterStop guessing gains from blog posts. A disciplined step-response test and three coefficients you measure yourself will outperform any magic number you found online.
- Ground your boards before you ground yourselfStatic discharge kills components silently. A proper ESD workflow costs less than replacing one microcontroller and takes thirty seconds to build into habit.
- Voltage dividers you can trust in productionSimple resistor networks fail when the load changes or temperature swings. Here's how to spec dividers that stay stable across real conditions.
- Sensor calibration you'll actually run twiceMost calibration routines gather dust in a comment block. Here's how to build the kind you'll invoke before every demo without groaning.
- The README is a jointIf the next person cannot reflow your project from the docs, the craft is incomplete.
- Power the weekend like it mattersA fragile rail is not a character trait. It is unfinished work.
- Knobs that feel honestIf the detent lies about the value, the whole device starts lying.
- Closed-loop or cosplayIf the robot cannot sense the thing it claims to control, it is performing robotics.
- Flux before confidenceA cold joint is usually a story you told yourself about being done.
