USB tomfoolery

Postby heiowge » Sun Sep 19, 2010 11:51 am

I need 4 USB male to female cables no more than 3 inches in length. The smaller the better. Or instructions on how to de-solder ports and attach cables.

Basically I have a hub with the ports soldered to the board. What I need is the ability to position the ports how I like.

Ok. I'll come clean...

I want to put this:

Into this:

With the ports in the centres and the cables coming out the back.

I've removed the casing and got a triangular board with the ports soldered on.

Any advice?

30 cm long. I've done business with the Dutch branch several times now.

Looks impressive, but since posting I've had a look see. I don't think I'll even have room for the 4 cables inside the cube. I'll be better de-soldering the USB femail sockets from the board and extending.

I haven't done anything like that in years. Any hints?

Google is your friend :P (you're not getting fishy-like, aren't you? :roll: :evil: )

Anyway: http://pinouts.ru/Slots/USB_pinout.shtml Connectors: Conrad, presumably Maplins too.

Ok. Google wasn't my friend that much! :cry: Thanks for that guide, but it doesn't help me when I'm more of a novice than that. Sorry. But I am. I am planning on buying my first soldering iron since 1990 at the weekend. That's how out of date I am.

I have this:

Image

I need to add about 3 inches of cable between the hub and the female ports, and I'm pretty sure I won't have the space to extend them using male - female leads.

Option 1: De-solder the female port and solder cables inbetween the board and female ports.

Option 2: Buy 3 male - female leads and cut them at 3 inch mark. Replace the female ports with wires from the female port leads.

I'd prefer option 1. It'd be cheaper.

Anyone fancy helping me through it? :)

OK, I see. Well, I don't know how good you are at soldering, but here's a few tips:

* Wait for the iron to heat up. Use some solder to melt a thin layer on the first 5-7 mm of the tip. More isn't a problem, you just waste some solder, no big deal.
* Heat the joints properly before applying solder. Molten solder will go towards the heat source!
* Don't move the joint until the solder has turned solid again. The joint should be hollow (unless you've applied too much solder ;))

* To de-solder, use a manual suction pump, made for this purpose. If the Maplins attendants are worth their salt, they can advise you which one would do the job and don't cost a fortune. Heat the joint, then suck away as much solder as you can. Sometimes it helps to add just a bit of fresh solder. Wiggle the component loose gently while heating the pins. But most of all: take your time!

Thanks. What colour wires are standard for the USB? Any particular order?

Maplins have started taking Paypal!!! :D :D :D

So it means I can use some of my cube sale funds to buy some stuff.

I ordered a new soldering iron, some solder and some of that solder soaking up ribbony stuff (I couldn't stretch the budget as far as a pump), and some heat shrink cable wrap. I'll slice up an old USB lead for the wires.
