Found a good source for micro size wire.


If you look at an IDE or floppy drive cable (any ribbon cable for that matter) you'll find 20 or more lengths of very fine stranded wire of high quality. You can pick these ribbon cables up for pennies at small computer shops, or pay a bit more and find them at CompUSA or the like. Hope this helps, I've been searching and searching for fine stranded wire for Li-poly hook up wire and the like, this stuff works pretty well.

another old classic is to use wire from old mice. Quite good stuff

Jim,
If you find the newer version of IDE cable, EIDE, the wires are even smaller, well at least the ones I've found.

Great idea guys! I'm a computer geek and have tons of that stuff! That wire would probably make a perfect RFFS-100 antenna.

Philip,

Besides trying to judge the size of the wires, is there a way to identify the EIDE from the IDE cables?

Dave,

The EIDE will have blue connectors while the IDE will have black. The stuff works pretty good, I've been using it for over 2 years now. Pretty flexible, but doesn't like heat too much so be careful with the iron. I usually will pre-tin the wire first.

Philip,

Thanks, every time I buy a replacement hard drive it comes with a new cable that I never use...probably have a bunch around somewhere.

How much current with these wires carry?

I'm thinking that this might be a good source to replace wires in the servos to lighten them.

Thanks


Thanks for the tip. I just wired up my RFFS for the first time and thought more flexible wire and stranded wire would be an improvement. The first two strands would be color coded, as well.

Good idea on the mouse wire Graham, there is some good long wires in there, and they can be found DIRT cheap. Fill: I'm still in the stone age and don't have any EIDE cables, are those the new 100 pin cables that I see now? Sounds like an even better source thanks!

I don't know how much current these wires can carry, but would be pretty confident in rewiring a servo with the wire. The GWS picos come with wire that is very nearly the same gauge. The only thing that you'll need to be careful about is wire color since the majority of the wires will be grey. The simple fix is to get a sharpie or two and color the ends of the wires.

Telephone cords have nice small wire inside, usually colored red, green, black, yellow. These are the wires from the phone to the wall, or the Modem to wall cords (everyone probably has a couple in the drawer by the computer). Small stranded very flexable!
The other suggestions got me thinking and cut open some spare cords laying around......

One consideration for those interested in saving the most weight possible is that plastic insulated wire is always significantly heavier than the same size conductor insulated with an enamel coating (technically some of these "enamels" are actually plastics but for clarity I'm refering to those wires with typically shiny ultrathin coatings that are removed by sanding, scraping, or in some cases, soldering).

One wire I'm having good recent results with is AWG 36 wire with a single polyester insulation coat. It weighs 2.95 mg/in and has no problem with currents of 200 mA (and quite possibly more) over our micro sized lengths (< 10"). Comparable plastic insulated wire can weigh several times as much.

Jim,
The actual connector is the exact same, but I think on the older IDE not all the pins are used. I'm looking at both cables right now, and my IDE says 28awg while my EIDE is 30awg.

another source for some (I think) 40awg wire is guitar pickups. There is a TON of it on the bobbins.
