Nice. I'd heard of the idea but didn't know it made such nice, neat wires. Good ida for when you don't have ribbon around. But I'm not sure I'd want to try it with the 2-3" lengths of wire I tend to work with on my robots :)
Who doesn't have ribbon cable around? Seriously!


not the multicoloured kind anyway

I ordered my first reel of coloured ribbon cable on Saturday night. Having seen in Oddbot's pics I just couldn't resist spend three times as much as for plain grey ribbon cable.

I learned the twisty trick from my grandfather about 40 years ago using a pump-action mechanical device that twisted metal sack ties. The second part of the trick, is not to twist the wires too tightly. If you do, there's a danger that you'll break the metal wire inside the insulation.

To safely make short lengths of the fancy twisted cables, I think you could just make an extra long twisted cable. Then you can cut the long cable to the short length you want, and spare your fingers.
we do about 200 ft at a time in work the same way with 3 colors. Thanks for letting us in on the idea.

yesterday i have used this tip to double the gauge of a chopper wire


you have a very nice face ctc :D

Cat 5/6 network cable (the blue one) contains 4 or 5 of those twisted solid core wire pairs.

Cat 5 UTP (unshielded twisted pair) has 4 pairs of wires. They come in both solid core and softcore/messy core (what do you call it) versions.

CAT 6 UTP looks and feels the same and basically is the same. The only difference is the quality of the cables (sometimes not even that), the shielding characteristics of the connectors and of course....the price.

It's been some years since I last looked at the specs for Cat5 and Cat6, but I seem to remember that cat 5 shielding is around the bundle of eight wires, where as Cat6 has shielding around each of the four pairs. This makes Cat6 mechanically stiffer than Cat5 - the minimum curve radius is larger and so it's harder to rewire old buildings with Cat6.
