bread board jumper wire pins
« on: January 11, 2010, 09:28:20 am »
I'm going to make my own jumper wires for breadboards, but I'm stuck for where to get the pin from that goes on the end of the wire..... where can I get them, I have a suspicion they won't come as: "breadboard wire pins" but what do I look for ? they should be approx 0.5 mm in diameter

They might be heatshrink end caps, never seen any that small though. they're a bit like the nipples used on TOS links for dust protection too.

i've seen the ones you mean on the pins from makezine and seeedstudio etc, i just use the 3m jumper wire kit which is just preformed bare end wire.

some people use the SIL idc type pins but they're can be too big and damage the contacts in the breadboard (depending on bb etc)

Making your own is a waste of time and likely costs you more than premade:

THINK AGAIN I have those and you know what ? THEY ARE GARBAGE ! the "protective bead" on the end is about 2.5mm in diameter and putting them next to each other is not fun as is trying to modify a setup, ever tried plugging one in between another two ? the wire is very thin. I cope with them but would rather have some better ones, I can get good ones from Maplin (the con artists) but they are hugely exspensive and do actually make it worth my while buying a real of wire and slapping some pins on the end.

THINK AGAIN

No, why should I? I know my numbers and the effort to do this. But I guess everyone needs to make his own experience. So have fun with these

£283.01 crimp tool http://uk.mouser.com/ProductDetail/Tyco-Electronics/58641-1/?qs=ZDXmSm13590PrmoGQBoEmA%3d%3d
£0.162 pin http://uk.mouser.com/ProductDetail/Tyco-Electronics/5-102107-3/?qs=My3Ssfv80AfRRM1SbQCMKg%3d%3d
£0.594 housing http://uk.mouser.com/ProductDetail/Tyco-Electronics/7-87499-2/?qs=HSGlLeu24BPSxiwgAnztQw%3d%3d

If we forget about the £283.01 crimp tool (no tool == more time wasted fiddling with the connectors), that is already £1.22 per jumper wire. Good luck beating commercial offers.

I use these...

http://www.allelectronics.com/make-a-store/item/JWM-100/100MM-BREADBOARD-JUMPERS-MACHINE-PINS-10PCS/1.html

...and they work fine. They're smaller than 0.1" wide (measured them 0.07" at widest just now) so they fit next to each other on a breadboard just fine. They have different lengths as well.

not sure what the links are for the crimp tool I guess was one but the picture was missing, the pin will be a peice of stiff wire and the wire comes at about £ 1/m I'll solder the wire on and put some shrink over it which is also cheap, its just a case of the time but if i consider the time and anoyance of using bad wires (at one point I could not see that I had missed a wire because the damn things are so flipping wide) then it's well worth it.

I tried your technique simon, and it worked out well.

At first I just put heatshrink on solid 22ga wire ends. But that felt kinda cheap, the nice thing about premium wires is they are flexible don't get all bent out of shape.

So I tried 22ga stranded for the wire. The pins are just the core from 22ga solid wire. Stripped the stranded wire about 1/2", then wrapped that around the solid pin, soldered, and shrink wrapped w/ about 1/2" of shrink wrap. I'd probably rather have 24ga stranded wire so it's more flexible.

Nice cheap solution, I'm not sure how fast one could crank these out though. I'll post a photo later.

There are 350 wires in that box, its ?21.57 + shipping.

cost wise it take me maybe an hour or so to cut, trim and sort those wires + the multicoloured wire + box to store them in, i don't think i could beat their price.
