Does anyone have a good reference for how to make connecting wires for Arduinos?  I am having a lot of problems with buying male connectors that are very flimsy and break off in the socket after just a little bit of use.  So, I thought I would try making mine own.

hi @starnovice,

I typically just solder the pins on the wire and heat-shrink them,  I have a crimper that's ok and works, but I find it fiddly to use and I can solder them just as fast and it will be a better connection. I also find the DuPont plastic ends very shotty.

I recommend some heatsink, male and female pins, nice wire (I have silicon 22awg), and an iron. I use a pointy conical tip for putting the wire and solder in the pins.  Use enough but not too much solder.  You can shrink it tightly with just the iron edge, but a heat gun if you have it.  I have one and for wire making, I usually skip and just use the iron.

@triform Thanks for your suggestion.  That is the same crimper I have and it does seem to destroy the small pins. I need to make some male pins that fit in the sockets on the Arduino.

Fit in the 2.54mm female headers? For that, I some times use male 2.54mm break-offs and do the same HS job.  Some of the ones pictured are that way.
