How to make an on/off button with intel nuc

[davidgilmour]

I have an intel nuc and this is the power button on the mobo. I want to attach a regular joystick button with some wire to it so when I push that button the NUC will turn on (or off).

It is the green button in this picture.



How do I attach the wire?

I also want to accomplish this Dave.  The beat I can figure is I have to find out what kind of button it is, remove the button and solder one in its place.  I am setting up a Intel Nuc 3 inside a NES (like DaOldMans Pi-tendo) and I want the Nintendo power button to operate the NUC itself.  If I had better soldering skills I would risk it but as of right now I am in limbo until I can find someone who will fo it for me.

Just solder wires directly to the button legs. I bet only one pair of the legs is actually used for switch purposes and the other is for support.



good day.

^This --- Just cut a piece of wire and remove the jacket from both ends -- hold one end to one of the 4 button legs - then while holding it there touch the other end to each of the three other button legs one at a time and see when the thing starts -- You now know which 2 legs are used to start the machine so solder a wire to each of those 2 legs and attach to a button and you're set.

Thanks, this worked. If you look at the photo it it is the bottom leg on the left side and the top leg on the right side, those 2 together did the job.

If you do this you will need to modify the button on the NES.  It is a latching switch and you want a momentary switch for your purpose.

Did this without solder on my Super Playchoice project. (Link in sig)

Don't solder the button

[ChanceKJ]

Just to elaborate. If you turn your NUC motherboard over there is a small set of header pins, some of them have colours painted at the base of the pin on the black plastic header holding them to the board. A pair of those control the same function as your little switch on the other side.

Depending on your motherboard model number they make look like these hidden in by the blue connector.

I dont know if you can modify that NES power button to be a momentary button (you might be able to), but another alternative is to find another set of buttons and unsolder the reset button from the second set and unsolder the power button from the first set. Then solder the reset button back onto the first set. Again, Im not sure, but it looks like the caps might pry off, so you can swap the old power button cap with the new reset cap. You then will have power and reset labels with both buttons momentary.
Another option is to rig up a small momentary button and glue the power cap on to it.
Im interested to see what you will do.
It would be neat to have power and reset buttons both work, since it will be easy to hook both to that board.
If you need someone to solder it, send me all the parts and I will do it for you. (not real sure about adding a different type button though as in last option, that would take some serious planning).
One other option is to use a capacitor to supply a pulse when you switch on the power button, but this may be a problem when turning the computer off, unless you be sure to turn off power button before shutting down.

Yeah, some nucs have the classic small pc buttons (mini atx) but mine doesn't have it, it has the one shown in the Opening thread. A bit more work but managable.
