Practical & Fast Way for Making Jumper Wires for Breadboard in Few Easy Steps




How many times you build your electronic circuit on a breadboard to test it before making the PCB or just learning electronics by building circuits on breadboard then it didn't work and you think it might be a burned IC or a bad transistor or maybe that electrolytic capacitor stayed on the shelf for too long and no longer working properly and after a long time of testing and trying things you discovered it's just a wire is not touching contact points of the happened to me a lot but when I tried this idea of making jumper wires from " Map Push Pins " my breadboard circuit worked from first trial so if you don't have ready made male to male jumper wires in your country to buy or you can't afford them or you just have an hour of free time then why not make them yourself.

Step 1: Tools & Materials

Tools :
1- Wire cuter .
2- Wire stripper .
3- Flat nose pliers .
4- Soldering iron and solder .

Materials :
1- Map push pins ( 4 mm diameter plastic head or less , 15 mm shaft length )

2- Solid core small diameter roll of wires .

Step 2: Preparation:

A- Cutting the Wires :

Cut wires to desired lengths ( I suggest short , medium , long & extra long like the standard ) .

So I made 16 , 19 , 23 , 29 cm so after taking 2 cm from each end to wrap it around the pin we will have 12 , 15 , 19 , 25 cm (standard for commercial male to male jumper wires ) which is good for a large breadboard

B- Stripping Wires :
Strip each wire 2 cm from both ends .

C- Twisting The Wires :

Turn the end of the wire twice around the first 1/3 of the push pin (from the head) and use a nose pliers to twist it tight

D- Soldering :

Just solder the wire to the pin.

Step 3: Safety

1- When using soldering iron be careful of electric shock or fire .
2- Lead is a poisonous material so wash hands after soldering .
3- When soldering there is bad fumes so use good ventilation .

Step 4: Hints & Tips

1- You can use alligator heat sink between pin head and the place of soldering so the heat won't affect plastic head. If you wish ( I didn't)
2- Some pins won't fit to breadboard cause pin shaft diameter larger than breadboard holes so before buying pins try it.
3- Don't buy pins that have shaft length more than 15 mm cause there might be accidentally electric short with other nearby pins.
4- Colored heads pins are good thing for terminal that needs polarity (battery clips , voltmeter clips ) but not necessary and also good to distinguish same color wires from each other when they are on the breadboard.
5- Larger pin head diameter than approximately 4 mm will prevent using near by holes on the breadboard.
6- A good way to store those pin jumper wires is to pin them on a flat rectangle piece of thick cardboard or Styrofoam.
7- If some wire's insulation got some shrinking cause of heat (near the solder area ) you can use a small piece of electrical tape or temporary just turn it around the pin when using it on breadboard.

Step 5: Additional Thought

You can use "map push pins" not only for jumper wires but also to :

- Speaker terminals .
- Battery clips.
- Audio in (attached to 3.5 mm jack ) .
- Alligator clips ( to clip voltmeter with it ) .

and keep them to be used on a breadboard projects .

Amazing idea! Really simple and practical!

Had a lot of wiring from an unused telephone patch panel and with this I just put it to use ;3

Thank you for sharing this!

Thank you very much and its a good idea to use copper wires from any source you can find to make jumper wires .

Take care

I prefer to buy pre-made breadboard jumpers myself but I've used push-pins like this as well to make quick-and-dirty tie-points for wires that lead off the board to a remote sensor, lamp, or whatever.
