I have had my RTMotion system since early 2014 and it has been indispensable, especially for gimbal and handheld work. The new Latitude modules are pretty dope too.

A couple months back, I sketched out an idea for an integrated monitor mount system. Eventually, it became the prototype you see here. There’s only a few minor tweaks left to do and then it's off to the machinist.

I am still working out pricing, but if you are interested in a pre-order, I would love to hear from you - please indicate your interest below with the type of power cable you would need (mini-XLR4 for TVLogic, dummy LPE6 for SmallHD 502/501 or dummy L-series for TVLogic's with attached batt plate or SmallHD Focus).

FYI, the ones you see here are resin and nylon prototypes. The production version will be CNC'd from Aluminum 6061 and type III anodized in black.

BASE UNIT
- screws to rear of hand controller
- locking L-series battery plate
- sends power to monitor and wireless video receiver via included Power Y-Cable
- powers hand controller via dummy LPE6
- houses control circuit for powering LED arm
- thin light profile, with styling to match hand controller

SIDE MOUNT
- Arri rosette for attaching left grip
- rosette axis matched to focus knob axis for weight distribution

PIN-ROSETTE ADAPTER **NEW**
- attaches to side mount
- mounts to regular light stand's 5/8" baby-pin

FRONT HARNESS PLATE **NEW**
- features tactical-style swivel stud for hooking on lanyard or neck-strap

TOP MOUNT
- Arri rosette for attaching monitor/rx mount
- ratchet-style M6 knob

MONITOR/RX MOUNT
- viewer angle adjustable via rosette
- supports monitor and wireless video receiver
- captive 1/4-20 screws (5/32 and slotted)
- removable anti-rotation pins for SmallHD monitors
- anti-slip rubber pads

LED ARM
- Bright White or Tactical Red illuminationation modes
- connects with Lemo and locks via captive screw

Shout out to Mike Gailing @ Teradek, Jin Lee @ TVLogic and Jon Walsh @ Anton Bauer for helping me with this project. And to Rich Hawkes @ RTMotion for the demo unit while you repaired my screen.

I'm in for use with a SHD702 (LP6 battery killer) and Paralinx Tomahawk RX (2 pin Lemo) and / or Latitude M. Thank you!

 

[Patrick Tresch]

Interested.

 

[Oscar Stegland]

Very interested. Are the cables removable? It looks like there's 2 Lemo out. Is that right? Also, is there any way you could check compatability with Boxx Atom? I believe they use Hirose connectors for power.

 

[Eric Oh]

Totally interested but would prefer to keep it monitor agnostic if possible as in my situation ACs would provide the monitor of their choice. Is that possible? As for the wireless I’m currently still using my Paralinx Arrow Plus as I’m waiting for Teradek to release their DSMC2 integrated Bolt transmitter.

 

[Bernard Jallet]

Interested !

 

[Linda Barzini]

Any chance of another version for Bartech?

 

[Patrick Tresch]

Could you make a plate for this battery? It's a really good one (small and powerfull).

 

[Kris Bird]

Holy crap, that’s really good!

 

[Patrick Tresch]

could the left handgrip be closer to the RThandset? So the left hand could also be usefull.

Liking what I see, personally would use it with a SmallHD 702.

I'm in for use with a SHD702 (LP6 battery killer) and Paralinx Tomahawk RX (2 pin Lemo) and / or Latitude M. Thank you!

Liking what I see, personally would use it with a SmallHD 702.

I originally hesitated on the 702 as I believed the rig would be too top heavy. However, I just tested it and it works fine. The 702 is actually a little lighter than a 58W with its heatsink. I’ll add the 702 to the compatibility list.

Regarding the Tomahawk R2, I will track one down and test it out. (Know anyone who could lend me one?) You’d think running a 702 and T2 will drain the L-series battery faster than a smaller monitor/rx combo. Couldn’t find the power consumption of a T2 rx online, but for reference, a 702 is 11W and the Anton Bauer NP-F976 used in the example photos is rated at 47Wh.

For the Latitude-M, I plan to add horizontal 1/4-20 threads so it will attach vertically behind the monitor, but this might interfere too much if you already have an rx attached? Would screwing it to the side hole of the 702 be sufficient? I will figure out some more options and get back to you. Also, I would do you a 3-tail power cable for powering monitor, rx and latitude.

Are the cables removable? It looks like there's 2 Lemo out. Is that right? Also, is there any way you could check compatability with Boxx Atom? I believe they use Hirose connectors for power.

The power cable is detachable and plugs in via an S-series 2-pin Lemo. This feeds power to your monitor and receiver. The other Lemo is for attaching the LED arm. The dummy LPE6 cable that powers the controller is hard-wired in.

Regarding the Boxx Atom receiver, that requires a minimum 9V supply. Currently my system passes through the L-series battery voltage. I have toyed with the idea of including a voltage step-up circuit to provide a 12V output, but I will want to see what the demand is on that before I decide to include it. An alternative for you would be to purchase Media Blackout’s L-series wedge plate which will give you a 12V P-Tap port.

As for the wireless I’m currently still using my Paralinx Arrow Plus as I’m waiting for Teradek to release their DSMC2 integrated Bolt transmitter.

Yes, my goal it to get the mount plates to work with as many monitors and receivers as possible so it could be an agnostic system. You may want to have a few different power cables to cover the range of possible monitors.

I plan to add extra 1/4-20 holes so you can attach a Paralinx Arrow in a vertical position.

Any chance of another version for Bartech?

If there is enough demand and someone can lend me their unit for a while (Bartech?), I would be more than happy to see if there is a way to do it.

Could you make a plate for this battery? It's a really good one (small and powerfull).

Interesting idea. A quick fix would be to use this adapter cable with a dummy L-series on the end. However, this means finding a place to secure the battery and my LED circuit will need a beefier regulator chip. The Anton Bauer battery shown in my photos is 47Wh, so only 2Wh away from your suggestion. At $60 each, it's not a crazy amount of money to invest with L-series. Nevertheless, I will look into how this could be done with the Hi-Q.

Holy crap, that’s really good!

Thanks, Kris. That means a lot to come from you.

This question came up during my design process. Originally, I was not looking at a rosette-based grip and was thinking of a 15mm rod wooden grip like this SmallRig type. Even though the grip could be flush to the controller, it couldn't rotate and I thought the ability to adjust your hand position was better suited and more comfortable. However, you asking this has made me want to reinvestigate this option. In case it helps, here is a photo of me using the rosette grip and my thumb still has good access to the zoom control.

 

[Nicholas Wise]

Trying out a heavier combo. Everything is working great.

 

[Nicholas Wise]

Question via email:

Ist their a option to mount it on a C-stand or or other stand for long studio days?

Yes, I am working on one. More info to follow.

 

[PC Greene]

Brilliant thank you very much! I'd be up for shipping our Tomahawk RX to you for sizing / testing. Perhaps we can talk ergonomics and Latitude as well?

If you allow for a baby pin to be put on the back so that i can mount it to a c-stand at times. i will take one.

Working on that exact idea. Would people prefer a male pin or a female 5/8 hole with side locking screw?
