Clap Detector Circuit

Build a complete schematic and PCB layout for an automatic clap detector circuit powered by a 5V battery.
It must include exactly these 3 blocks connected via a "Wake" signal:
  1. An electret microphone with an LM358 op-amp that sends a 5V pulse to the "Wake" line when a clap is detected.
  2. A 555 timer configured as a retriggerable monostable. It must use an IRF9530N P-MOSFET for power gating, so the 555 turns on for 5 seconds after a clap and shuts down completely during silence to achieve zero-power standby. Add a yellow LED in parallel to indicate when the 555 is active.
  3. A toggle flip-flop switch using a second LM358 op-amp that turns a separate yellow LED on with one clap and off with the next. Use a 100nF capacitor on the non-inverting input so this LED always starts OFF when power is connected.
Place a solid ground plane on the bottom layer.

No schematic or PCB changes were made; the project remains empty with 0 components and 0 nets. The requested design still requires circuit-level review—particularly the claimed zero-power standby, 555 retriggering/power-gating topology, and LM358-based toggle implementation—followed by schematic capture, verification, PCB placement/routing, and a bottom-layer ground plane.
Execution stopped because your ACUs ran out.
