Chris, have you tested your battery pack to find out which of the pins is ground and which 12V?

Once you find that out, building new battery packs is rather easy. I recelled myself all of the batteries I received when I bought my camera.

Well, I haven't got any experience with steadicams, but if the batteries do give out 12V, you definitely can run Eclair ACL from that. You'll only need a power cable with the 4-pin jaeger male connector on the ACL side.

 

Building such a cable is easy, sourcing the jaeger connector might not be. Easiest solution might be to source an ACL power cable and then replace the battery end connector with a new one for the steadicam use.

How much work would it be to replace the Jaeger on the body to a XLR? Since i know people have done it.

I have done it. It isn't that much work, but in order to do it you have to remove the motor first (carefully), then open the camera base and de-solder the connector. As there is no space for a XLR connector in the ACL 1.5 base, you'd need to have a cable "tail" come out of the camera with the XLR connector in its end and then also find a way to block the opening left by the removal of the Jaeger connector -- then secure the wires inside so that you don't accidentally (by pulling the XLR connector) tear the wires out. This was the more time consuming part of the hack. I can tell the details how I did it if you are interested.

Seems like if I stock up on Jaeger connectors I would be better off. Not I just want my ACL to get some hours of shooting.

Maybe the easiest way is just to get or make a short cable with 4 pin XLR at one end and Lemo or whatever you choose at the other.

Best option, agreed.

Yeah but I still have Jaeger on my body, so XLR does not really make sense...

4 pin XLR is the usual power connection on 16mm film cameras. but there's no reason why you have to convert you camera if you don;t want to. It's pretty standard on batteries (unless you're going to use a  video camera battery), so worth having one on your battery. Also worth having two power cables, since they can break at inconvenient times.

Before the ACL II it was Jaeger on the camera and 4 pin XLR on the batteries,  then with ACL II it was reversed with 4 pin XLR on the camera.  So the same power cables work for both.  I assumed that Carl had a standard ACL power cable with a 4 pin XLR on the batt end,  but maybe he does not.  Worth picking one up,  will be cheap used.  Maybe someone on the forum has a spare...There were long spiral cables in the earlier days,  then short straight ones came for the onboard batteries.

I actually have 2 cables with jaeger contacts. And Jaeger batteries. Not XLR.

But if any 12v will work, my cable guy can probably make a jaeger to D-tap cable.

I thought I'd add to this discussion, I have got one of these batteries; It's 12 volts, it's small and light, I bought it off ebay, it works pretty well for my ACL II.

My plan is to go from D-tap from V-mount to Cannon 4 pin. I'm either going to use the original camera mount that runs along side the mad or devise something else.

The standard on board mount, IMO puts a lot of stress on screws for that little casting at the back of the camera, which may not matter, not sure, but I never liked the idea. If you can customise something, for example just lets you velcrose a light battery against the mag or mount the battery on the side of the rod base etc, I think it's a good idea....

 

EDIT: Shedding the onboard battery is a good idea, just having it on a belt or a sling over your shoulder. Makes the camera lighter. The ACL II is getting heavy, so it helps..

Anyone knows if technically you could run the ACL of a Anton Bauer VCLX battery?

I am thinking of making my Eclair a production camera for a short in the spring, and together with a video assist, that could be a killer idea. Only problem would be running a lot of it.

I am open to attaching a gold mount / V-mount as well to run it, but I am not sure it will work as good.
