Hello boys and girls I'm very new at this. So please excuse the stupid and basic question!
Would there be a problem with making jumper wires from old  S.C.A.R.T leads.   
Thanks Simon

Hi scart leads are a conection between TV DVD player and so on

I think he is asking about using them for the white prototyping boards ( forget what they
are called ). The ones you poke the parts and wires into.
I suspect most of these cables are made with stranded wire.
This is not useful for the prototyping boards. Check with someone that does phone cables
in building. The wire they uses makes good jumpers. They usually just toss the end cutoffs or
send it to the recycler if they have enough to make it worth the time.

Thanks phone cable seems to be a good idea. 
As for the scart leads yes they are stranded  I was going to solder a pice of stiff wire on the end.

Not cable, wire. Most housed cable are stranded.
Most wiring in building it done with twisted pair single strand
wire or double twisted pair.
It is not cable.

Get yourself a piece of ethernet cable (you know, the [usually] blue network cable), CAT5, CAT5e, etc... they are all great!

Inside them there are 8 individually insulated, solid wires, color coded, and that are perfect for using on breadboards. That is how I get most of my jumper cables.

Ethernet cable is extremely cheap, and large pieces of it can often be found in dumpsters. I have 50+ meters of old ethernet cable that was taken from an old office when my company was moving in. The whole floor was being remodelled and none of the existing cabling would be reused, so I got several meters for myself, to be used as jumper cables. Over 5km of CAT5e ethernet cable was disposed of (actually Furukawa made a disposal arrangement for us).

I don't spare them: I cut to length on each project! It makes my breadboards look beatiful!

Keep in mind, however, that they are horrible for soldering, since solder don't stick to them and their insulation is not resistant to high temperature.

I personally think the wire in CAT5 cable and the wire used in phone lines is a bit too thin to work reliably in many breadboards.

I have lots of phone wire but I gave up using it with breadboards because of all the connection problems it caused.

On the breadboards I use (all of them form DX), I get a tight fit with CAT5 cables. Again, the fact that they are color coded is a huge advantage.

The only breadboard that isn't ok is a very old, Brazilian-made breadboard I've had for 20 years. I've abused it so much with thick pin inductors, potentiometers, HV diodes and the like, that most of its holes are expanded. Even commercial jumper cables will fit loosely on it.

That's good to hear. My breadboard must have been past its prime. I'll try my phone wire again sometime when I have a fresh breadboard.

Wow thanks. I found some crimp on male and female pins on ebay which are very useful.

Why not to prefer these pre-made jumper wires bro?
