I was going to suggest that too . . . I use
a drill motor to create lengths of twisted
pairs for later incorporation into a project.
You can capture on end of the pair in
a vise; the other end in your drill
chuck. Run the drill until you get about
1/2" per turn pitch on the twisted
assembly. Release the rotary tension
carefully . . . some wires will react
rather amazingly to become a snarled
tangle if allowed to freely 'relax'.
If your drill runs both directions,
you can drive it 'backwards' enough
to reduce the rotary tension before
you take it out of the chuck.
I've fabricated twisted pairs of 10 feet or
more with this method.

Please tell me more about calving sheds in Tasmania (https://bisonconstructions.com.au/steel-buildings/dairy-buildings/calving-loafing-barn),
how well they are
built, which technologies are used (and which technologies are needed?). Maybe
timings are also important - if, for example, they build it too fast, it may
affect the quality badly? As experienced farmers say "calving sheds should
be those good to want live there yourself) Wish I can succeed in this business.

Yeah . . . as we write, I'm loading the
truck to go put up lights on the
poles over some calving pens. First
time in 6mo that bucket truck,
weather and people all came together
on same day.
The work site is 25 miles out of town out
in the Gyp Hills . . . one of those
jobs where you load up with everything
you know you will need and as much
stuff as you think you might need!

If you do this with all your wires, invest in multicolored wire.=C2- If
you've got runs to three different devices, each with a ground, you can hav
e white/black, green/black, and red/black.=C2- It isn't absolutely necess
ary for functionality, but when it comes time to troubleshooting/adding/rem
oving/replacing devices, you'll love it.
Also, if you have four spools of wire, build a box with a rod through it an
d hang the spools side by side.=C2- Then you can spin them together as Bo
b suggests straight from the spools, and spin off exactly the length you ne
ed each time.

Hi All
Whats a nice way to finish (say) a free 12 run of just two cores of 22awg w
ire?
For instance to the bulb of a flight instrument.

Bob, you are too kind. Thank you for your offer and I acceptjavascript:emoticon(':D')
. And I'm happy to cover any expense on my behalf.
Eyebeam Mini Specs are here: http://www.aveoengineering.com/eyebeam-mini/
Aveo EMI Filters: https://tinyurl.com/y3epopac
Aveo suggested remedy: Attached
They also suggested multiple loops around the ferrite cores. Haven't tried that
yet.
Original request to Aveo:
Request:
Technical help please. I have installed an EyeBeam mini in my composite airframe.
The shielded, twisted pair power and ground wire cable parallel unshielded,
untwisted wires to the cabin speaker for a distance of about 5' . At that point
the cabin speaker pair becomes a twisted and shielded cable. The two cables
parallel each other for an addittional 12'. The shield for the speaker is grounded
at the audio panel and the shield for the EB is grounded at the ship's single
point ground bus. The problem: When I key the microphone, the EB turns on.
If I key it again, the EB begins flashing uncontrollably. It is unresponsive
to the dimming control and the on/off switch. The only way to stop the flashing
is to disconnect the EB from power. The EB works fine when connected to battery
power independent of the ship's electrical system. Attempts at a solution:
Thinking that the the magnetic field of the speaker magnet may causing the
problem, the speaker was disconnected and the mic was keyed. The EB exhibited
the same uncontrollable flashing upon keying the microphone. I recognize that
the problem does not lie with the EB. But I'm hoping that your design engineers,
knowing what the EB's vulnerabilities are, can look at this and determine how
to remedy it. Thank you, John Burnaby

found a better manual that called out
0.2A at full bright on 12v . . .

These are wAAaayyyy to beefy . . , but
they might work. What I'm going to send
you is much smaller.

that works . . . someone also
reminded me that I've suggested
shielded wire for things like
compass lights, etc.
use shield for one side, center
conductor for the other.
