Working on a breadboard, one can get used to the benefits of being able to readily plug and unplug jumper wires to reconfigure a project. One could only dream of doing so with PCBs, right? Wrong! [Stewart Russell] recently shared a tip on Twitter on how to do just that, with the help of a little fishing wire.
The trick is simple: on any old development board that uses 0.1″ pitch headers, simply weave some fishing line through the plated through-holes in the PCB. Then, regular jumper wires can be inserted just like on a breadboard. The fishing wire has just enough give to allow the jumper wires to be jammed in, holding them steady and in good contact, while still allowing them to be easily removed.
[Hackspace Magazine] has raved about the trick, noting great success using 0.38 mm fishing line. Alternative methods involve using toothpicks, though we suspect solution is likely messier and less reliable.
