View Full Version : Power on at AC plug ( without pressing Power button )

08-05-2013, 11:11 AM
I would like to start my console automatically when then console is powered on through AC Adaptor ( without using power on button ).
Do you have ideas on how could this be accomplished ?
Thank your.

That would work great if you were building an Ouya into a mini arcade cabinet or something. I can see how this would be handy. I don't think we will see a concrete, easy way to do this until we get a custom ROM running though. I'm sure someone with more technical prowess will post in here at some point though. :)

I found a solution : blocking the power button on pressed position.

Wouldn't blocking it cause it to pull up the power menu in-game later. Good idea, but simply wouldn't work. I do have an idea though. You need to find the two power connectors on either side of the power button. It should be visible, but if you cant determine which two it is, use a current detector, and it should detect current when you hold the button down. Once you have found the two connectors, you can solder two wires to them, separate wires. After you get these two wires on (sometimes just bending them tightly around the connector will work). you need some other form of switch. Any switch will work, just connect the two wires to it, and TADA. There are some wireless switches out there, you just have to find one that is only connected while you hold down whatever button it is. Otherwise you will get the same problem as just holding it down.

It would take some testing with a current detector, but it could be done. You would flip the switch on, once the ouya is powered on, switch it off. As if "On" is you holding the button down.

So you;d have to turn it on, wait, then off for this too.

Another thing I was thinking of is making some sort of circuit with a 555 timer. When the 12VDC is applied, have it do one quick cycle connecting either side of the switch and then stop. There may be another way and that may not even work. I'm not that great with actual circuitry but looking into it might be a good alternative.

I have no idea how, or why you would do this unless you're making an OUYA cabinet as DP said.

With StockPlus Rom (https://plus.google.com/111642288177726387415/posts/UNeY5rBUHie) I know that when I click "y" to power off it sleeps both the console and tuns controller off and to wake just turn controller on. Works really well. Its not like it wates any power even when its on let alone idle/sleep. Less then an alarm clock. Works just like an xbox would only no boot needing to load.

Hi there,

I'm also looking for a similar solution. I'd like to install OUYA in the car and would like it to power itself on automatically when I start the car.

1. Is there any Software mode available for that ?

2. Will permanent 'shorting' of a power switch work properly or it is not a good idea ?

Thank you!

Try this: It may get you where you want to go, simply solder the two noted points. (https://drive.google.com/file/d/0B1qN94HXTKpHc2lwQS1mam9KcFk/edit?usp=sharing)
The two points are what gets short-circuited when you press the power button.

To test this, simply unplug your OUYA and hold down the power button and then plug in the OUYA. I did this test and it seems to work just fine. So if you solder the two points noted in the link above, you should be good to go.
