World Domination Part Two - Making a Cable
My first attempt, a headphone 1/4" jack. It is a cheap one out of Maplins. I have used some speaker cable pulled apart to make up the three cables needed for the signal, return and earth. The jack when taken apart has the connection with little tabs with holes in them. The aim is to solder cables to each tab ensuring there is no contact with any other part or else there will be shorts. There is a plastic tube protector and then the cover with a spring inside which acts a strain relief for larger cables.
Firstly I tin the ends of the cables and then using pliers make a little hook and thread that through each tab hole. Make sure you put the case on first!
Then I soldered each wire in turn onto its tab
Since I am using thin cable I pinched the two end tabs for strain relief as the spring will not hold the cables
Then slide the plastic case into place
Then screw on the metal part of the case
Finally, one cable! Well it just a practice! Next, I will use a mini - jack.
Please note that some of the terminology is made up as I do not know the correct words. I also intend to get a volt meter to check that each wire is carrying a signal when it comes to the real thing. With electricity you have to be safe
