Raspberry Pi - PSU

Add a soft-power switch to your Raspberry Pi

Similar projects worth following
This project allows the Raspberry Pi to be powered ON or OFF from an external power button similar to the XBOX's own soft-power button. It's all through-hole components to make it easier for people to populate on their own.

Enjoy this project?

@matt If you don't need a lot of precision, you could use the R3 (the board above) by reprogramming the uC.

In the new design, both the RTC and uC talk to the RPi through I2C, I guess I could tie in the alarm to the uC and make your wish come true. ;)

RTC would be great, with an alarm function on the RTC to wake the PI, and a pin from the Pi to initiate shutdown. That way a PI could go to sleep for an hour, wake up, do 10 minutes work and then sleep again.
I'd be interested in helping out with that.

The 5V adapter also powers the Pi itself, no need USB power. I'm working in a new version of this board that has an integrated RTC and it's all relatively simple to solder SMD components (i.e. much smaller).

This could definitely be helpful for well integrating RPis into stuff. Does this board take 5V and provide it to the Pi, or do you still plug the USB power in on the Pi itself?
