Kenyon Gyros. The cables that send them their power seem pretty small. Is there a minimum AWG rating to send this power down? 115v at 30watts and 400 Hz

Is there any reason (interference) why this cannot go down my coiled cable inside my sled?

I want to send one of these down the AR connector in my MK-V sled. I like having a Gyro on top of the camera and one at the bottom of the sled. Sure I could just have a front cable but this is an interesting idea.

Thanks

Hi Thomas,
I wouldnt do that if i were you.
There is enough interference without adding 115v right next to video cables in the AR coily cord wiring.... probably best to keep it external...

The only time AC and DC play nice together is when Angus swings the guitar and Brian is at the microphone...

The reason that gyros run on AC is the fact that the units were originally designed for the US military (okay actually for naval applications as Ted Kenyon was an avid sailer and to stabilize his binoculars on his sailboat he converted a gyro that he used for instruments he was building for planes, AC is safer and more efficient) to be used to stabilize binoculars, sextants, cameras and to an extend film cameras for reconecance missions and the current used in Planes and Helicopters is AC, yes there is a DC circuit but is not used as it's low draw.

Anyhow

You want to keep them separate. Larry Mcconkey would be a great person to talk about that as he did just that or at least used to have that. But not in the same cable. He is using an Ultra. The center post "cable" is actually 'Individual Cables' that are bungied together, so adding an additional cable is fairly straight forward. But it's not in the same cable but in a separate cable going down beside the main center post cable.

And on an AR for sure as the cables are already under sized as it is. I see a nice meltdown happening there. If you really have to have an internal cable pull a separate cable running beside your original Center Post cable and isolated it properly...

Cables, cable... cable... enough...

Wait a minute...
You have an AR... what do you need the Gyros for???


Anyhow,

Good Luck,

Erwin

Thanks guys, I'll scrap that idea and send the one gyro up over the front (back of the monitor) as I do already. Nope, I have not got an AR but I do have lots of sockets and plugs for one.
