Hi Piclisters, I often use 0.1 male headers, female sockets and pins to make interconnects, jumpers and other wiring connections between boards or between boards and i/o devices. I like them because they fit on breadboards during prototyping, they are flexible (Make ok board connectors for example) and cheap. Lately though, I have been making a lot of them for various experiments and it's starting to be a real pain to attach the wires to the pins. In the past I ignored this because I never made more than 1 or 2 at a time. At the moment, I need to build quite a few and my failure rate is too high. It's also taking me *WAY* too long to build simple 3 and 4 wire interconnects. My current technique is to carefully strip my wire, crimp the connector to the insulation then solder the wire. If I am not *VERY* careful, the pin does not fit the female socket. The pins tend to stick, twist or fall out. If it matters, I generally use cat5 network cable - I pull out as many conductors as I need, cut to length and attach my connectors. I use the cat5 for two reasons: I have a 1000' spool (that's the big reason :) ) and I find that it's a versatile hookup wire in general. I have been looking for a tool, techniques or maybe a better brand of pins so I can make my life easier. I would appreciate any suggestions. If you have the current Jameco catalog, see page 126 for the headers and pins I use. A typical part number is 108337 (header) and 675850 (housing) and a variety of pins. I would really like to get a proper tool to do the job but would like to avoid being locked into a specific brand of connector or a very expensive tool. Appreciate your help!
