I've seen a lot of hacks lately for making a USB DS power cable or an emergency powerpack and all of them have one thing in common-
you hack up a DS power supply.
I have an old SP headphone/power adapter I picked up for $2 that I'd much rather sacrafice.
Problem is I have no idea which pins are the power and ground. I have some guesses but I'd rather ask people who know.
Thanks.
My DS power supply has the pins labelled on a little diagram. I'd be surprised if the SP wasn't the same way.
Ah, so it does. I didn't think to check my power supply.
Thanks.
And as I'm still new to working electronics, a couple people really tried to impart to me "ground doesn't always equal negative".
I'm 99.99% sure that I'd be safe in running my usb ground wire to my ds negative wire. This sound correct?
That .01% is enough for me to openly admit ignorance in the attempts to save my $150 DS, which I'm rather fond of.
Thanks again.
In this case you can safely equate - with GND. GND is, technically, zero volts. You can have negative voltage (JAMMA for example uses -5v) as well as positive. Typically a battery has a negative and positive terminal, instead of + and GND.
But yeah.
