The Jumpers... while waiting for delivery...

It's too bad that the board delivery is delayed... well, rather than be saddened with it, might as well start something...

As mentioned earlier, I wanted to make special jumpers to go with the new board... here it is... the material required are the pin headers, the mating socket, wires and heat shrinkable tubes...

Bend the sockets on the strip 90 degrees and hold it as in the photo... By tilting the socket backward, melted solder will not flow into the socket making it useless... solder at the center wings and crimp the wire after that... doing it on the strip is much easier than holding single socket...

Do the same on the other ends to the pin headers... just be careful because the plastic can easily melt...

The pin header end after soldering and heat shrink tube applied...

The final result... plug the pin into the socket to test for functionality...

Some of you might ask why all this trouble, so here's the reasoning...
  • The pin header will plug snug into the prototyping board and the socket will form reliable connections to the IDC headers on the development board
  • The heat shrink cover will do two things; prevent shorts and acting as strain relief thus, if properly made, the jumpers will last you a loooong time.
  • These jumpers are meant to bring the signal from the IDC headers to the prototyping board... on the board itself, a normal hookup wires is enough...
