Simple 'power on' switch?
-
@Zigurana Hi Zigurana, when you say similar, what changes did you make? This looks a perfect solution for what I am thinking of. Thanks

I also run a pi3, my solution is to put a momentary contact switch across the "run" header.(on pi2 it's called pin6) when my pi is in lower powermode this brings it back with the press of a button. i cut a small hole in my case and superglued the switch in place.
for permanent use i've added 2 pins through the holes for the run header, this way i can pop open the case and unplug anything attached to the top half.
difficulty easy 5minute job.
required tools/parts,
soldering iron, dremel(or a sharp knife)
one moumentary contact switch(i harvested mine from an old pc case reset button) with wires/jumper
2 pins for the run header(de soldtered from an old motherboard) -
@Graboid my script looks a little different, is all. No functional difference.

@Zigurana said in Simple 'power on' switch?:
I use something very similar to what is described here.
This requires only a single button, two wires, and a single script to monitor the pin.
It will allow you to shut down the pi (or at least go to minimal power mode) and turn it back on again.Okay, so, using the advice posted by @Zigurana, I purchased a simple momentary switch.
I went ahead and got some jumper cables and used a couple for COM and NO.Given the nature of this kind of switch, I knew it didn't matter which cable went into which terminal of the switch, and I simply had to connect to pin 5 and 6 on my RPi 3.
This definitely did the trick. I can now simply press this button when the RPi3 is in its low power state, and it'll come right on. This is exactly what I need, and it works great.
Given that making the script and using the full function of the post @Zigurana linked would be pretty easy, I went ahead and got that script written up and working too. I can't say I use the switch for powering down, as I simply 'shutdown' from emulation station, but it's good to know it's there if I need it.
Thanks for the input everyone.

I also want to ask.....I have the USB with the switch built in...
Can I just put the code in for a power off and then use my switch? I have seen people using wires across pins...paperclips and with the code, they say its fine?
thanks

@pc4life0427, using this switch is the same thing as pulling the plug.
-
@Zigurana yes I know that.. that is why I was asking about the code.. if I add the right code will that work? I am looking at doing a switch from GPIO.. but if I can run the code then shutdown from start menu etc..
-
@pc4life0427 I do not understand your question. Do you mean to use two buttons, one on the usb cable, and one on the gpio's?
-
@Zigurana I want to stop using the USB.. yes.. that is why I was asking about GPIO...
But I have seen code for proper shutting down.. then I can use the USB switch I have to then turn off completely
-
@pc4life0427 Yes. For that you can use the script I linked to above.
Regarding using the cable switch as well, unless you are operating on battery power, I dont see the point. The remaining <1 Watt (120mA @ 5V) (source) is negligible otherwise. -

@Zigurana thanks..

@Brewskii yes I am subbed to him.. he makes great videos...I watched it.. being in Japan it's hard to get cheap switches... I did find this one on Amazon.. was thinking about putting on top of case..

Hi fellow Gaijin.
Old topic I know but regarding the switch. Here a couple sites that sell all kinds of switches and parts here in Japan.
I thought I leave this here for others to find. -
@FlyingTomahawk thanks! 👍🏻

@SloTayHolmes I second the Power Block (new version of the Control Block I am using). Not only does it do what the OP is asking for powering up the Pi, but it's great when something goes wrong and you can't exit an emulator or need to shut down but can't get to emulatorstation.

pc4life0427 i'm getting the switch you posted a picture of soon how do you attach the button to the raspberry pi 3 because I have a Pi 3 in a Tinytendo64 case, with a red status LED replacing the already 3D printed red part. How do you use the button and where do you put it in the case. Also, how do you put a script to the button to serve as a safe On/Off switch?
-
@raider2747 sorry I never installed. I bought a Nespi case and used code to shut down from forums
-
Try following this video tutorial. Worked wonders for me.
-
Nah I'm not going to get that case and LED and the power button I'm getting the Element14 Pi Desktop case now it has a safe shutdown power button u should get it watch the ETA Prime video on it
