The electronics of the Krieger Dreamer Peeper, with very ad-hoc construction.

- The switch on the lower-right turns the Peeper on.

- ATTiny85 is on bottom-middle. It generates science-fiction sound effects and flashes the lights.

- LM7805 voltage regulator is above ATTiny

- Logic-level MOSFET on the left amplifies the audio signal from the ATTiny

- Switch on top-left switches audio source between ATTiny (sound effects) and the mp3 player (human voice "extracted from dreams")

- Logic-level MOSFET out of view on the right powers 20 10-watt LEDs

- Capacitor on top-left prevents brownout when LEDs are flashed

- 120-Watt speaker on top-left plays sound effects

All parts were scavenged from the parts bins in Bloominglabs.
