Breadboard / Banana Jack Cable

In this Instructable, we'll be looking at making a very useful component for anyone who makes a lot of test circuits on a breadboard. The Breadboard / Banana Jack Cable is very quick and easy to make, not to mention cost effective. (Forgive the less than perfect quality photos, my cellphone is of terrible quality)

Step 1: Gathering Your Tools / Materials

The following is a list of what you'll need to build this; all of which are fairly easy to come by:

Wire Cutters / Strippers
Wire Crimpers
Soldering Iron / Solder
Electrical Tape or Shrink Wrap (Your Preference)

Hookup Wire (I took my wire from a scrap ATX power supply; It's pretty good quality and works well for this project)
Banana Jack Plugs
D-Sub Pins (I had to take a photo from ( since my camera couldn't take a decent picture of one - These pins can be found with most D-Sub connector kits found at Radioshack / The Source)

Step 2: Preparing the Wire

Start by Stripping about 1/4 Inch off each of the ends of the wire you've chosen. Make sure that each wire you've chosen is the same length as the other.

Step 3: The Banana Jack Plugs

Now we're going to attach the Banana Jack Plugs to one end of the wire.

Start by taking off the plastic cover from the Banana Plug (First Photo).

Now you'll want to take the naked Banana Plug and  (depending on the type of plug you bought)
crimp or solder it to one end of the wire.

Make sure you don't forget to put the plastic cover through the wire so that you can easily connect it to the Banana Plug once you've finished crimping it.

Step 4: The D-Sub Pin

After attaching the Banana Plug, we're now going to attach the D-Sub Pin to the other end of the wire. I suggest using "Helping Hands" to do this otherwise it may be difficult. Other than that, this step is straight forward; Simply solder the connector to the wire and either wrap the soldered area in electrical tape or shrink wrap.

Step 5: You're Done!

So now you have a versatile connector for many applications!

This connector works great with my Shelf Panel Power Supply or any other Banana Jack Compatible Power Supply and work well with most Digital Multi-Meters to test circuits directly on the breadboard.

    i was just looking at the instructable mentioned below about freindly multimeter, Then i thought well why not just make breadboard freindly test leads. excellent write up also another thing i will be adding to my list soon.

    Yesterday, Sunday, I was bored so I went surfing Instructables.
    I found an Instructable called Breadboard-friendly Multimeter and I thought, what a great idea but too much hassle compared to what I created myself.

    What I have are Multimeter leads with breadboard wire pins attached to the ends.
    I thought that maybe I should create an Instructable showing mine as an alternative.
    Then ten minutes surfing later I found this Instructable.

    While slightly different, it does exactly the same job.

    So rather than create an Instructable myself I thought that I would endorse this one.
    I made my first set years ago and have proved invaluable, so this is a brilliant Instructable to help all breadboard users.

    I have also modified one pair of Multimeter leads with crocodile clips, and another pair of leads connected to a two pin connector so that I can monitor the power lines on the breadboard. All part of my everyday electronics toolkit.

    Often a piece of hookup wire and an alligator clip and I'm done myself. Not to say that I haven't done what this Instructable describes plenty of times too!

    Here's some prior art:

    Wow, nice massive breadboard layout. Do you ever use all of it?

    Its a bit more crowded today.

    But no, so far I've never been at a loss for tie points on it yet.

    Good use for all those old D-sub pins I have laying around from aprevious life.   Nice!
