I'm currently setting up tests with few break-board mounted chips from SparkFun (color sensor & motor driver). The ultimate idea is to make a robot as a summer project with the kids. The typical breakboards come with spaced holes for headers/soldering. I like to avoid soldering during the initial quick-prototyping phase, when I mostly want to try the functionality with the Arduino, loading libraries, reading values, etc...
In this prototyping mode, I usually fold some solid core cable into a little pin that fits tight in the small breakboard hole. The thing is that often those solid core cables pull themselves out of the board, making testing unrealiable on the physical plane. (--> read frustrating :-)
Are there off-the-shelf connectors/cables that can offer a good connection to the breakboard perforations? I'm thinking of some sort of small spring-loaded tip that would let you easy attaching/detaching to the breakboard contacts/holes?
