Introduction: Make a Mini Prototyping Breadboard
I often find myself needing to do some quick tests on my electrical components or just try out a small schematic. My breadboard works well, but is a bit big for my liking. Because of this, I made myself a smaller one from old computer IDE cables. It works great for when I go on trips because it is so small I can take it anywhere. T
Step 1: Gather Your Materials and Tools
You will need:
- 2 to 4 IDE cables
- some small gauge wire
- soldering iron
- a knife
Step 2: Cut the Heads Off
The first task is to remove the wires from the IDE cables. It helps to put the cables in a vice for this step. If you look at the ends of your cables, you will notice a small piece of plastic holding the wires down. To remove this, you can try to pry off the little triangles on the sides, but I find it is much easier to make two small cuts on each side that let the holder piece slide right out. (the pictures will show you what I mean) Next, you should be able to just peel the wires off from the head. You can save them for another project, but you won't need them again for this one.
Step 3: Begin the Somewhat Tedious Work
It's a good idea to break off the little bump that some cables have on them. It works well to just crush them with a pair of pliers. Now your task is to solder all the little pins together that you want on one "rail". I chose to make them go across the cable head, but I left the last two on one side of each row of pins alone for power rails. I found it was easiest to put the wire in first, solder the very first and very last pins to the wire, and then solder all the other ones. Do the same on the other side then repeat on the other three cable heads.
Step 4: Put Them Together
The next step is to glue the four cable heads together. Once you have done this, you can solder on the rails that will go perpendicular to the others you made. (in my case, the rails I will be using for my power rails) The process is the same as before only the wire has to go in a sort of zig-zag because of how the pins are offset.
Step 5: Finishing Touches
Finally, cut a a small piece of cardboard to glue to the bottom of your build. I also painted on a white line to identify where my ground rails were. It works really well to attach a 9 volt battery to the bottom of your board and then run some wires to it.
