Wire soldering
From DP
Of course before soldering anything you need to get the tools and suppies:
[*] Total expenses
In addition, you will need the following stuff, could be bought locally:
1) Stainless steel high quality scissors
2) Ruler - to measure the length of wire
3) Permanent marker - to mark the cut points
4) A4 paper sheets - to use as disposable surface
5) Lighter - better with a hole to refill it later
6) Toilet paper roll - for technical use only ;)
Now, after you got all this, you noticed that 20 cm copper wires are too long for you: decreasing the signal quality or just a little bit inconvenient... This manual below (with nice pictures included!) will help you to learn some basic soldering, giving an example of:
.
=== How to reduce the length of 1P copper wire from 20 cm to 10 cm ===
.
So you got this 20 cm copper wire. Look at the picture above, isn't it nice?
Measure about 5.5 cm from both ends of wire and mark these points
Now cut a wire at these points
Although the isolation could be removed by something sharp (scissors or knife) it is inconvenient for 1P wires - too easy to cut some of the wire's hair-thin strands! Here is the alternative way:
1) prepare some toilet paper near you, make sure that you can take and use it very quickly
2) set fire to the wire's end using a lighter and let it burn for one second
3) quickly (!) : blow out the fire, take a toilet paper and through a toilet paper (to avoid burning the fingers) pull the burned insulation from the end of wire before it cools down!
4) if you did 2)-3) not good enough you may need to repeat these steps
5) remove the tiny remains of insulation from the end of wire - using your nails
^^^ you will be able to do that in less than a minute after some practice
Get a shrinking tube of good diameter and length. From a set that I linked in previous article, this is a half of 1mm shrinking tube. Then put it on a wire
Prepare the soldering equipment. Place some A4 paper sheets below it to use as disposable surface (later you will roll them and throw away with some tiny remains of soldering supplies)
