i'm playing with a gravity bike project and i've put a spin mag on the front. i don't want to try attatching the computer pickup to it, so i was gonna try setting it up on the back wheel.

the lead for the pickup sensor is a little too short though. can i splice in some wire without affecting it's accuracy, or weather it works at all? it's a cheap schwinn labeled computer from walmart in case that matters. haven't cut it yet so i'm also wondering if it's just one conductor or shielded or something?

not interested in wireless, at least not for this bike. it's a cheap for fun project and actually the computer was amoung most expensive pieces i got for it (a whopping $12). thanks for any help.

There's probably 2 wires in there. Splicing in some added length shouldn't be too hard. Make sure you insulate the splice joints individually afterwards.

Yes, I have done it. Use solder and heat shrink. I actually soldered in a plug, and six extra inches to make my folding bike quicker to pack and un-pack.

Here is a pic of my work...

It will be easier if it is a twin wire, if it is a shielded core type cable (like co-ax) it is still possible to splice or add plugs, just not as easy (depending on the connectors available to you.

thanks all. i've stripped back a little of the insulation and now see two of the tiniest strands of wire i think i've ever seen. at first i thought it was strands of one conductor and still though it was tiny.

i'm hunting around the house for another old computer wire i thought i had to match up the size as best i can, but if i can't find it i guess i'll go with whatever i can find that's pretty small. thanks again.

How about cutting up an old set of headphones? They often use ridiculously skinny wires. It is hard to strip and solder wires that thin, but it's doable. You can actually use any size of wire for this application, but I can see why you might want to go thin for aesthetics or flexibility. As mentioned above, heat shrink tubing makes the whole thing a little neater than electrical tape.
