The parts are in place and the generic passives are configured as through-hole. I’m wiring the 555 astable now: ~1.06 Hz with a 1kΩ/680kΩ/1µF timing network.
The schematic is now wired. I’m verifying the netlist and ERC checks, including the 555 mandatory reset, control bypass, and supply decoupling connections.
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.

Demo Complete
The demo is finished. It didn't use any ACUs. You can now continue working with this project like normal.
