Here's a simple one:

I'd like to convert my Kinect 360 to use standard USB following this as it's currently a non-standard USB connector and device requires additional 12v. But I'd like to add a diode to add a bit of protection in case someone attaches a wrong polarity PSU plug.

Can I add a diode inline on the 12v line? If so, what type and value do you recommend?



Thanks.

 

If the data & clock and the 5V from the Kinectside are USB compatible, apart from the 12V then, yes, I can't see any issues with putting a diode in line with 12V input.

The diode current specs depend on how hungry Kinect is, a 1N4007 can take 1A max.

Yes, the wiring for the wires other than 12v rail are standard usb. Its recommend to use a 12V 2A psu for the kinect 360, I'm not sure 1N4007 is enough. Would a 1N4008 be ok as it looks like theyre rated for 3A?

 

Hello,

I never heard of an 1N4008. It could be a rebranded chinese fake.
Have a look at the following tables for 1A and 3A diodes:


I hae also attached the full datasheets.

I asked Bing AI. Maybe it just made it up! Others it recommended was 1N5400 or 1N5402.

Looks like the 5400 from your tables looks ok to use.
