Built the schematic for a hand-solderable 9V NE555 red LED blinker and renamed the project 1 Hz 555 LED Blinker. It uses a 9V battery holder, SPST slide switch, DIP-8 NE555, through-hole LED, axial resistors, and leaded capacitors; ERC/review checks show no open warnings or errors.
Open items:
- PCB placement/routing has not been done yet.
- Blink rate is nominally ~0.99 Hz; electrolytic capacitor tolerance will shift the exact timing.
Docs created:
Suggested next steps:
- Place the through-hole parts on a simple PCB.
- Route the board.
- Add silkscreen labels for battery polarity, switch ON direction, LED polarity, and 555 orientation.
