Cheap bread board jumper wire!!

by whiskey on Sat Feb 20, 2010 9:52 pm

If your looking to save a few dollars you can always pick up some CAT3/CAT5 (ethernet,phone) wire from your local hardware store for just over a $1.00 per foot. The good thing is that it consists of 8 pieces/different colours/8 feet in total of AWG22/24? wire perfect for bread boarding :D

I also recommend picking it up in small lengths (around a foot) because the wire is wrapped in pairs of two so it's going to take a little elbow grease and patience to get them unwrapped but what else you got planned for the day!

Great idea! I use this myself and it is pretty cheap.

One thing to beware of: some CAT-5 comes in stranded-core format. The solid core is great, but stranded-core and proto-boards do not play well together.

Something else that I like is using male pins from DB-xx type plugs. Crimp one of these on each end of your jumper wire, and then use a short piece of shrink-wrap tubing on the crimp part of each pin; walla! instant professional proto wires. These are much more durable and will last much longer.

Scrap wire can be useful in places, but you need to be careful not to damage your breadboard or break off a wire inside one of the holes, especially if you bend solid wire too sharply or too many times.

The adafruit breadboard jumper wire kit for $6 which has the pins on it already seems like a modest enough investment. It looks like the Arduino starter kit and experimenter's pack include them too.

When I was a kid, I got a lot of my hookup wire supply from a 30+ ft piece of 25 pair telephone cable that had been discarded. it was a project to break out all of the pairs and roll them up but you get a lot of different colored pairs.

Discarded cat 5 patch cables (because the tab on the RJ-45 connector has broken off) can be a good source of stranded hookup wire. Not for breakboarding though.

we also used to use telephone wire, but those wire bundles are nice for the first 'run' of prototyping (which is why we snapped them up!) usually for a proto we start with 'em but then move to 22awg to get nice small jumpers that are less messy

Not a bad idea, I think I will try that. Currently I've been using 22 ga solid wire from radioshack, works very well and is relatively cheap: http://www.radioshack.com/product/index ... Id=2049742
