    Here we see some moves on the new software, the items positions are programmed (using "target") in and then the tracking 'just happens' - Im not concerned about focus at this point.

    Wow! Looking good Sam. I have no expertise when it comes to the software side so you are miles ahead of what i do. I'm more on the mechanical side. Are you building to maybe sell or just for your own use? I have a few photos of rigs i built over the years including my little crane, but all use either DragonFrame or Mantis. Is what you are building realtime or more for Stopmotion? Or for both?
    When i got into this it was back when i heard DF had a motion control interface included and then i found that they gave you all the scripts for the Arduino! Nice. Then i found Mantis and that is pretty much what i use. It can run on its own as a stopmotion software or it can interface with DF in various ways.
    Good luck with your project and if you need any advice on mechanics maybe i can help.
    Cheers.

    Hi guys, Hey Doug, so glad to hear from you, I'll send you a a private e-mail with some details of the latest-greatest I've been working on for your feedback. Glad the Facebook site is back! Doug, your work is inspirational, and I've also gotten lots of ideas from the Kazakhstan group with their Ankl system. Those guys are the master of "next level" DIY...

    Sam, fantastic and very cool! That's a lot of effort on the software side for sure.

    I've been finishing a new pan/tilt/roll/focus head designed for attaching over or under slung on a moco crane... I've been spending more time on the focus side of the work...

    It's currently bolted to my worktable, so I can only shoot what's around the room. I just did a few focus tests I can share, all with a 50mm Nikkor AI-S at f 1.8 on an APS-C sized sensor...

    Here it is hitting 11 focus marks over the shot...

    And here is a similar shot, but with multiple passes to allow dissolves...

    I'm trying to make the most of our universally crappy situation and do some things that I enjoy. Top of that list is DIY moco!

    I dont think it is robust enough to sell - even though it cost $000s and took a couple of years its very much v1 and I dont understand vibration and backlash enough for this to be saleable. Also the core gearbox was quite a thing on the lathe

    Its a commercial venture though as I will shoot iwth it for money.

    Its time, not realtime, I can use various motor configurations from an ungeared neema23 (v fast) to a 100:1 neema 17 (v v slow)

    So that can be from Phantom through to timelapse (with or without stops) but stop motion would imply a stop of n as you move the puppet, which I cant do with complex moves.

    Sorry guys, I have to remember to come over here to check on things. Anyway, yeah, the old basement studio/workshop. How i miss that. Even though it was very cold in the winter and probably not to healthy due to lots of dust. Im going to re-upload the vintage motion control pics sometime in the next few days. Right now i am doing a Busking FB page to entertain friends and family. Just me and my geetar. Hope everybody out there is staying healthy and sane!

    Cheers guys.

    How are things coming along with the rig? Would love to see anything new you have shot on it. Recently started working on some motion control rigs during the covid downtime. Was able to turn an old pvc tripod dolly into a motorized setup that could also be put on a dana dolly.

    and clean up some wiring to get my 6 axis mini arm up and running. Still need to tighten an axis and add some encoders to the motors:

    Hi
    Completion of the software was to some extenet completion of the device.
    As for testing and new material ive realised the need for decent af to do tricks I have not done before.
    The old tricks are here http://framedogs.com/motion-control-camera-bristol/

    As it happens ive now got an af camera coming today (nikon z6) and Im feeling more confident to visit the studio which I have not done since C19 has been in town.
