Re: Basic automatic power supply

You might be ok with a Rev A board - as they will use less current.

I would say you are pushing it a bit for a Rev B board though.

I guess you could always use a 750ma rated power supply - then you should never go over, but you might under power your Pi under heavy usage.

Re: Basic automatic power supply

No problem! Glad to hear it inspired another project. I would say your circuit is too basic to be safe...some resistors would be helpful as mentioned. The relay used in mine is nice because it has an audible click. The max current you mentioned yours can take is 800ma...I would say that is too low t...

Re: Will this harm the RasPi or SD card ?

You could have a button located nearby that connects to gpio and shutsdown the pi safely before cutting the power.

As stated before with a relay and a battery backup power supply this would even be possible without a separate switch.

Or alternatively as stated above a read only SD card.
