DIY wire-wrapping tool

Wire-wrapping is a very handy way to connect wires to PCB pins, especially in two scenarios:

  1. As an alternative to soldering, in order to be able to easily recycle the components.
  2. As an alternative to female jumper wires, in order to save some vertical space (sometimes jumper wire connectors are just too long).
