- Fuse selection before the smokeFast-blow versus slow-blow matters when your weekend build decides to pull three times its nominal current. Pick the fuse that protects the board, not your assumptions.
- Inrush current limiting you won't regret at 3 a.m.Your bench supply clicks off when the project powers up, and suddenly Saturday is a troubleshooting session. A few cents of NTC thermistor or series resistance can save the evening.
- Decoupling caps where the datasheet actually wants themBypass capacitors aren't optional decoration. Place them right or watch your rails bounce when the load steps.
- Linear regulators when switching feels like overkillWeekend projects don't need buck converters. Sometimes a quiet 7805 and proper heat management are exactly enough.
- Power the weekend like it mattersA fragile rail is not a character trait. It is unfinished work.
