I had a few questions concerning the type of power inlet that the xbox uses, often referred to as a shaver lead or figure of 8 connector, I'm just wondering how it is possible that the connector can be plugged in either way, The power connector consists of 2 pin holes, I'm guessing Neutral and Live which are wired to set pins on the plug, how can the PSU be powered with the connector either way around, surely this would be switching the Neutral/Live.

That brings me on to my next question, is there a certain order in which a figure of 8 power inlet should be soldered to the xbox PSU, which pin takes the blue and which the brown cable, I'm referring to the colour of the small piece of wire that connected the PSU PCB to the original xbox power inlet.


btw the power inlet that Im wiring up is one that mounts to the backplate of the DVD player case my xbox is being rehoused in, its slightly different from the original power inlet instead of two rounded pin holes one is rounded and one square, the socket still has the same Amp and Volt rating, why the difference?

thanks in advance

There are two types of current; AC and DC.

With DC, you have one positive wire and one negative wire (the current always travels one way).

With AC, you still have two wires, but the current changes direction (according to a sine wave, by memory).

Most electronic devices use DC power, though what comes out of the wall is AC. Hence the need for a PSU (such as you'll find in an X-Box or PC): it handles the conversion.

Because AC alternates anyway it doesn't matter which way round you plug the cable. When wiring up a power point in the wall I think the wires should go a certain way (doesn't matter inside the X-Box), but I can't recall how or why...

so any power inlet pin solders to either point on the mobo PSU

any idea whats with that connector I described? is it ok to use in place of a figure of 8

So long as it doesn't have any power converters etc built into the cable (they'd be hard to miss), it should be fine.

I need some advice about drilling screw holes for mobo standoffs, I'm using these plastic standoffs.

Says screw type 6-32, I dont have a tap and die kit so I've resorted to drilling plain holes for the standoffs, they fit ok but do not lock, Tried drilling a few holes I only have 2mm/2.5mm HSS drill bits so I ended up widening the hole more with a dremel diamond wheel. What exact size drill bit will I need to drill a hole for these standoffs.

Does anyone have a pinout diagram that shows how to connect a scart socket to Xbox A/V socket, the only guide I can find is this and its a bit of a hassle to work out which pins of the male connector equate to the pins on the underside of the PCB that the female scart connector is soldered to.

thanks
