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
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 (parts.digikey.com) 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.
