[edit] Summary
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.
- Two 5-Watt 30-ohm resistors on the left limit the current from the MOSFET.
- Switch on top-left switches audio source between ATTiny (which generates sound effects) and the mp3 player (which plays audio "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.
