Magic smoke

Old electronics joke: components work because they contain magic smoke. When the smoke escapes, they stop working. In EUC context, it means your control board burned something - MOSFETs, capacitors, traces - and now you have a very expensive paperweight.

Why it matters beyond the joke

The joke carries real weight in firmware debates. Conservative firmware limits (nannies) exist specifically to keep the magic smoke inside. The manufacturer would rather tiltback you into annoyance than let you push current levels that fry the board.

The trade-off riders argue about

Some firmware approaches prioritize protecting components: cut power before the board burns, even if that means the rider goes down. Others prioritize rider safety: deliver all available power and let the board take damage if needed. Neither is objectively correct. Both have consequences.

555 take

The magic smoke is funny until it’s your board. Respect the thermal and current limits of your wheel. Those “annoying” firmware restrictions are the difference between a board that works tomorrow and one that doesn’t.
