Have you or anyone heard of this http://www.ebay.com/itm/IR-Remote-Control-Switch-Module-Power-Button-Module-for-Raspberry-Pi-3-2-Model-B-/222412691189?hash=item33c8d456f5:g:CaQAAOSwTuJYprud.
It looks like it should work, anyone know if it needs script? Or does anthing you do need script? Thanks again

How to set it up

Remove your TF card and connect it to your PC or laptop with TF card adapter.
Modify /boot/config.txt file as following, for example, my pi is Raspberry Pi 3 model B:
device_tree=bcm2710-rpi-3-b.dtb
dtoverlay=power-off,gpiopin=26
dtoverlay=pi3-act-led,gpio=21
NOTE: device_tree=PARAMETER is depends on your Raspberry Pi's model.
more info please access this link:
[Device Tree| https://www.raspberrypi.org/documentation/configuration/device-tree.md]
Raspberry Pi model Device_Tree Info
Raspberry Pi B : device_tree=bcm2708-rpi-b.dtb
Raspberry Pi 2B : device_tree=bcm2709-rpi-2-b.dtb
Raspberry Pi B+ : device_tree=bcm2708-rpi-b-plus.dtb
Raspberry Pi 3 B: device_tree=bcm2710-rpi-3-b.dtb
Install the library of wiringPi and Download shell script to check the GPIO pin's status:
sudo apt-get install -y wiringPi
cd ~
git clone https://github.com/yoyojacky/powerbutton.git
cd ~/powerbutton
sudo mv ~/powerbutton/gpioshutdown /etc/init.d/
sudo chmod +x /etc/init.d/gpioshutdown
Edit the initialized file in /etc/rc.local :
sudo nano /etc/rc.local
Add those three lines before exit 0
sudo /etc/init.d/gpioshutdown
gpio mode 25 out
gpio write 25 1
After edit this file, Press "Ctrl + X" to save this file and Press "Y“ to save it.
Reboot your Raspberry Pi and plug power button on your RPi, press the button to test.
Have fun.

That looks awesome! It looks like the power on-off switch will work with a momentary switch! Thats amazing, the powerblock needs an always on toggle, this could REVOLUTIONLIZE my atari builds, hahaha. I'm going to order one and try it out.

Capeman

... But i will need to desolder that IR sensor and put it on a wire, what an odd placement, You'd think that would come as a separately mounted piece. But still, this excites me! If it works, this will be my replacement for the powerblock, and the price is right too!

Here's a no-drill option:

@KillerQ
no drill...but solder...i dont know....on a permanent intallation, maybe, but i use my Pi for all kind of stuff....

Capeman

Agreed, the cheap power HAT or the script/button/standby option in the earlier video seem like much less permanent options.

Re: Power on and off
I had a go with the last video, that with borkin button by Etaprime. It's relatively easy to solder and it doesn't need the script to power on, because it probes a pin that awakes Rpi by design. You only need the script to shutdown the Pi, but I don't think it's much needed since almost every distro, uses a safe shutdown method anyway.

That's if you don't need the analog A/V out of course and you don't want to drill the case.

KillerQ

@zupi

Thanks for the compliment. That button is my idea, that's why it's named after me. Glad you're getting use out of it!!

The audio and video out still works if you remove the button.

Enjoy!

It's one single wire soldered completely beneath ge board. It's totally out of the way. Give it a shot!

zupi

@KillerQ Your idea?! Well done pal! Actually I always wanted to add a power (ON at least) button but was afraid to drill the case and break any or end up with something ugly. A few days ago I saw the video and when a nearby store dropped the price of those jacks to 2€ I grabbed one to test if was working... And it did!
Good job everyone involved.

Although i don't use the A/V and the button is beautifully hardly noticeable, I still wonder if a jack splitter, although ugly, may give both power ON flexibility and A/V out but I doubt I will soon test it.

Thanks for the positive feedback, I appreciate it.

If I can get around to it, I'll try and test the splitter. If you get to it first, report your findings back here.

Thanks again!

I found a splitter. I'll test it out this evening.

Is there an easy way to hook up a Super Nintendo Power button to a Raspberry Pi? I know nothing about soldering.

space cadet

Soldering is simple. Try it out on some junk components first. The worst thing that will happen is you try again. Trust me trying out a new skill is rewarding! You can pick up a simple soldering iron cheap.

A Former User

Meh, I don't know. I'm really not old enough yet to solder by myself, and I don't think anyone I know knows how to solder.

space cadet

You could learn in less than an hour including research. It's fun and easy! Your choice and not trying to be pushy. I just like to try new things for myself to learn .

A Former User

Huh. Might try it.

zupi

@KillerQ Nope... Two stereo audio splitters I tried didn't do anything. Possibly a 4 segment mini jack Y splitter might do but it seems there are only 1 or 2 in the entire universe from a not so toughtful Google search. Like this one maybe:

Blimey...

Yea, no luck here either.

BUT, anytime you insert or remove any type of 3.5mm jack, it triggers the button sequence because it bridges the circuit.

So, to shutdown, just remove the jack. To turn on, plug the jack back in. It was always this way.

Hopefully that helps your situation
