9V LED Blinker
Worked for 2 mins 57 sec
Implemented the 9V hand-solderable red LED blinker schematic using a TI NE555P DIP-8, through-hole LED, slide switch, PP3 9V battery holder, axial resistors, and through-hole capacitors. The 555 astable is set to about 1.06 Hz with ~50% duty cycle, so the LED blinks roughly once per second; electrical connectivity checks are clean.
Open items:
- PCB layout/routing is not done yet, so airwire DRC errors are expected.
- Generic passives have through-hole packages and values, but not exact manufacturer part numbers yet.
Suggested next steps:
- Assign exact MPNs for the generic resistors/capacitors if you want a manufacturable BOM.
- Move into PCB layout: size the board, place the battery holder/switch/LED, then route.
- Add silkscreen labels for battery polarity, switch ON/OFF, and LED orientation.
Assign exact passive MPNs, then move into PCB layout and route the board.
Thought for 3 sec
The schematic is complete with a DIP-8 NE555, red through-hole LED, slide switch, 9V battery holder, and through-hole passives configured for approximately 1.06 Hz blinking.
I couldn’t assign exact passive MPNs or begin PCB placement/routing because the account currently has no available ACUs. Remaining work is to select orderable axial resistors and radial capacitors, define the board outline, place components, route all nets, and run final DRC checks.
