Any interesting power supply options?

Post by WillAdams » Tue Mar 31, 2015 1:25 pm

Asked after this on Twitter and the most interesting idea was to use an XBox 360 power supply, which is certainly inexpensive and easy to source.

Esp. interesting to me is that it affords both 12V and 5V if I understand things correctly?

also both a pc and xbox power supply have a 5v "always on" line in addition to the regular 5v line. meaning if it plugged in it provide 5v even when off. in pc PSU this is 2-3amps on the always on line on newer ones as far as i can tell. no clue how much xbox would provide tho

Maybe a stupid question but what is the advantage of the 5v 'always on? I was looking at one of those 24v enclosed PSUs but I know I have both of these lying around somewhere

as long as psu is plugged in you can power anything that run on 5v and less than 3A (on most newer pc psu's) without having to turn it on and power motors or whatever you run on 12v. and it seperate from the "powered on" 5v line that has the higher amperage available. so lights, microcontroller, webcam, fan, whatever u can think of that u might want running with out using seperate power supply or powering up motors when u just want a light to help see as u make calibration adjustments or examine what you made or something.

or project for any uber geeks....
make a motion activated welcome message for when u approach your shapeoko that always on

edit: was talking about PC psu only. no clue what amperage xbox one provides on always on 5v but doubt it 3A
