DIY Arduino and Breadboard Jumper Cables From Scrap Electronics




About: Maker, hacker, DIY guy who is really good at improvising. In case of apocalypse, i will be weapon maker! :D

This is my first instructable and here i'll show you how to make breadboard jumper cable out of some scrap electronics that you can find anywhere (in old printers, telephones, computers etc.). It's easy, cheap and affordable to anyone, and you'll recycle old stuff instead of just throwing them...

Teachers! Did you use this instructable in your classroom?

Step 1: Tools and Materials

From materials you need:

-Old scrap electronic boards (in this instructable I'll use old computer motherboard)

-Jumper cables from various devices (printers, telephones...look for smd electronics, I'm sure you'll find what you need)

-Heatshrink tubes (mine was 2.0mm, they are smallest that you can find, i think)

-Soldering flux and solder

From tools you need:

-Soldering iron

-Small screwdriver


-wire cutter, pocket knife...

Step 2: Female Ending (if You Dont Need It, Just Ignore This Step)

First, you must remove female jumper pins from plastic housing, for that you'll need small screwdriver or sharp pocket knife, gentle press tin contact trough hole, untill you bend small tooth that hold it in housing...or lift small plastic tooth that hold pins in housing, its all depend on wich type of jumper you find, after you done that, pins will just pop out of housing...just look at pictures, you'll figure out. DO NOT CUT WIRES FROM PINS.

Step 3: Male Jumper Pins

You'll find it on old motherboards and pcb's, you'll just need to look..after you find them, first remove plastic holder that hold them toghether, untill you have just pins on board, but be carefull, you dont want bended pins. When you remove plastic holder, you can desolder them from motherboard easily

Step 4: Making Jumper Cable Male End

Firstly, you'll need to remove plastic from end of a wire, about 5-6mm, then wrap cable around desodered pin you desoldered from motherboard, apply some flux and solder them again for cable witch other end has female end. When you done that, cut some piece of heatshirnk tube, and apply it for that end.

Step 5: Secure Female End of Jumper

Put female pins on board, like is shown on picture, than put heatshirnk tube and heat it untill is wrapped around must firstly connect them toghether, because male pin will prevent heatshrink tube to hold it too tight...

Step 6: Final Product

CONGRULATIONS! You make your first DIY jumper cable, you can experiment with both male or both female endings, depend on your needing...thanks for reading this instructable, and sorry for my bad english, i'm hoping you'll understand this :))

    Great idea! Thanks for sharing. I've run short on male pins for my "pigrrl" project. I was thinking I could cut a metal paper clip? Could this work?

    Great idea,never crossed my mind,ive thrown thousends of them away over the years,not now i wont, great thing about this i can make longer ones that you just cant buy,i think the market for these jumper wires is poor.

    I find it realy hard to buy these in the lenghts you want they allways make you buy a bundle of wires and you only seem to get the ones you all ready have hundreds of and never many of the long ones,while on the subject any one know of a good place to where i could perchase these in lenghts i want and the quantitys allthough i can make them its nice to have "pro" looking wires lol

    I done my own jumper cables before (ISP cable) but I didn't thought of adding those pins (and I have a few dozen of them). I just twisted the ends firmly and applied solder... man, I feel dumb right now ;)

    Also, great close-ups, they describe what you did very well. The pictures made further away are sadly a bit blurry, try to solve that issue next time. Otherwise it's a great (first, congratulations!) instructable, simple, helpful and well documented instructable. Thumbs up, dude!

    PS: Don't worry about your english. As long as you try your best (and use punctuation and start sentence with a capital letter) it's easy to understand. I've read waaaaay worse stuff written by native speakers ;)

    Thank you very much! :) I took pictures with my android phone, and I know they are blurry, but when I take close up pics, I taped some lens with small piece of ducktape to the camera, and I took close up pictures just like that :)) Hope I buying better cammera soon :)
