coax wire
« on: December 05, 2016, 07:53:23 PM »
After trying out a few different types of coax wire (Cooner is expensive, and didn't even have the suggested wire), this is pretty much the thinnest wire I've been able to get to work (and only at lengths around 5ft.):
https://www.digikey.com/product-detail/en/alpha-wire/9438-WH033/A9438W-10-ND/6003378

It's pretty cheap at $13/10ft.
Even this wire has unreliable connection (DAQ software goes redscreen soon) at 10ft, but 5ft seems stable (on desk- haven't tried on mouse).

Any other favorite wire suggestions?

I too tested a bunch of wires and independently found this wire works well. Very light, cheap, and still solder-able.

Also, the ST450 is a handy tool for stripping the wire.

Have you tested the mouser wire that is suggested on the miniscope excel sheet?

http://www.mouser.com/ProductDetail/Temp-Flex/50MCX-37/?qs=E6DKRd2RbT838FMsx%2Fl87Q%3D%3D

I bought it but haven't tried it yet, however it seems awfully frail and a tenth of the price. Is this not a good option?

I received the wire, but couldn't think of a way to reliably strip it, let alone solder it. 42 AWG is tiny. The tool I linked to cannot go smaller, and I don't know of any other hand tools. There are machines that strip to that size, but cursory glance was $5k/machine.

You *may* be able to burn off the insulation with fire. May be able to use a razor, too, but good luck.

And after it is stripped, the heat from soldering will probably damage the insulation, so even after all that, you could short it soldering it on.

I consider myself pretty compliant with these micro electronics, but just don't see the need for this level of headache that has too much chance for failure.
