Premium Members Sarah Thompson Posted July 17, 2012 Premium Members Report Share Posted July 17, 2012 Hi folks, I've been experimenting recently with an Atomos Ninja HD recorder. Seems to work really nicely, I'm happy with the results, and going straight to Prores is really nifty. However, its out-of-the-box power solution is kind of nasty. It has two Sony NP-F style battery mounts on the back and no other power connectors. The standard (small) batteries supplied with it are just giving about an hour of record time each running ProRes HQ, which (duh) isn't remotely enough to be useful. It can accept larger NP-F style batteries, but since I'm trying to move my rig to AB gold mount for everything, I'd rather power it from that. Thing is, I can find gadgetry that will let me hook an AB battery to it, as if I was powering a camcorder, but I'd rather be able to power it from the same battery as the camera (which might be on a steadicam rig or mounted to the rail system with a cheese plate if I'm using sticks). My Google-fu is failing me -- does anyone know of a suitable adapter (i.e., 12V in, fake 7.4V NP-F battery out)? If it was not for the weirdness of needing a fake battery rather than a plug, I'd probably have just built my own little power regulator, but...

Premium Members Eric Fletcher S.O.C. Posted July 17, 2012 Premium Members Report Share Posted July 17, 2012 They are making a d and p tap adapter for it. I'll have the first one to test in a few days with a samurai which we are testing trying to solve a record flag issue with the Alexa Quote Link to comment Share on other sites More sharing options...
Premium Members William Demeritt Posted July 17, 2012 Premium Members Report Share Posted July 17, 2012 Eric: any day would be nice. I can't believe how long it's taken them. Quote Link to comment Share on other sites More sharing options...
Premium Members Sarah Thompson Posted July 17, 2012 Author Premium Members Report Share Posted July 17, 2012 Hi Eric, Who is making the adapter? Atomos or AB? Thanks, Sarah Quote Link to comment Share on other sites More sharing options...
Premium Members Benjamin Treplin Posted July 18, 2012 Premium Members Report Share Posted July 18, 2012 Build my own one. Lemo 0B-306 to Samurai. Sony PC-100 batteries can be of use. Quote Link to comment Share on other sites More sharing options...
Premium Members Sarah Thompson Posted July 20, 2012 Author Premium Members Report Share Posted July 20, 2012 I just bought a used Sony clamshell monitor that happened to use the same batteries. It came with a power supply/charger with a fake battery. I popped it onto the Ninja, and it powered it just fine, so I therefore have a mains power solution. I'll probably modify the cable and build an 8V regulator which should make it possible to power it from about 10V to 25V. I don't know if the Sony parts are still available, but I can dig out the part numbers if anyone wants them. Quote Link to comment Share on other sites More sharing options...
Premium Members Benjamin Treplin Posted July 26, 2012 Premium Members Report Share Posted July 26, 2012 Surprise! Guess what was in my letter box today.... Quote Link to comment Share on other sites More sharing options...
Premium Members William Demeritt Posted July 26, 2012 Premium Members Report Share Posted July 26, 2012 Really? That's it!? Just as large as the batteries, but with a Dtap plug on top? I mean, that's good for hiding the voltage regulator, but I was hoping for something less bulky. Does it include a male-to-male Dtap?

Premium Members Benjamin Treplin Posted July 26, 2012 Premium Members Report Share Posted July 26, 2012 Nope, just the adapter. They added two longer mini BNC to BNC cables. Quote Link to comment Share on other sites More sharing options...
