MaciNap is a small PCB which shuts down the analog board and slows down PWM fans when the screen is blanked.

Screensavers prevent CRT burn-in, but won't save your analog board or flyback transformer.

Whether you're taking a break from Tetris, struggling with writer's block or have your SE/30 set up as a server, giving your analog board a rest will extend its life and save power until you return.

MaciNap monitors the video signal and shuts down the analog board once the display has been blank for about three seconds. When resuming from sleep mode, the video signal is suppressed until the sweep circuitry stabilizes, to avoid bright lines on the CRT. A single amber LED on the board indicates status.

MaciNap generates two fan PWM signals which have a duty cycle of 100% when video is active. During sleep mode, they're reduced to 50% and 75% duty cycle, reducing airflow and noise.
