[altusmetrum] wires

If you like to attached stranded wire to screw terminals you should crimp
the ends in a ferrule. Tin soldering is not a good idea since the thin is
pretty soft and flowable which might lose the connection.

Betreff: Re: [altusmetrum] wires

 

I have always steered away from the solid core.  Most of the time where
space isnt critical ive used machine tool wire, but doesnt work with the
"smallness" of the Altus Metrum products.(16ga).  I bought some smaller 26ga
stranded, becuase another altimeter i have, the MFG suggest 26ga stranded as
the "smallest" wire that would be safe.  this was after I discovered blue
color on the copper of the ematch leads. (now i suspect chemical reaction of
the bare copper, oily fingers, and BP residue.) Oddly its almost too big for
the TM i have.

 

I have never tinned the ends of my wires, but the belkin cable i cut up the
other day suprised me that the wires were stranded copper, and seemed
suitable for this. I always envisioned they were like old telephone cable
with that fiberstuff, that would be unsuitable.  Maybe with this small of a
gage i should solder tin the ends for added reliablity?  
I have litterally hundreds of feet of the stuff, and would be a "freebe" for
the rest of my av-building life.

I guess thats why we test!

My only worry would be that solid core wire doesn't like vibration very much
but stranded wire doesn't do well in screw terminals. I would think it could
definitely handle the voltage, especially since its such low duty cycle.

Anyone use cat5e cable for thier avionics bay?

Making a small launcher for the kids, i noticed the 4 twisted pair i
have would be a good match for my bay?

Its good for things like telephones and data signal, but what about
ematch voltage?
thinking the sheething and twisted pair may be good at RF shielding?
